The first-generation Trooper, introduced in September 1981, was available as a three-door wagon or a soft top with independent front suspension. The soft-top model sold slowly and did not last long. In the Japanese market, the car was originally introduced as the "Isuzu Rodeo Bighorn", but the "Rodeo" part of the name was soon dropped.{{citation needed|date=August 2023}} Early engines included a 1.95-liter gasoline and a {{cvt|73|PS|0}} 2.2-liter diesel, lightly powered even by early-1980s standards for the vehicle's {{cvt|3700|lb|0}} empty weight. The four-wheel-drive system was engaged by operating a three-position shifter adjacent to the transmission shifter. Both Aisin manual-locking and Isuzu's own auto-locking hubs were employed.

In 1983, Isuzu introduced the five-door version and the 4ZD1 four-cylinder engine {{cvt|97|PS|kW hp|0}} 2.3-liter petrol engine. Apart from higher power, changes to the previous engine included a Kevlar timing belt replacing the previous chain, and a larger two-barrel carburetor. Also available only for 1986 in the US was the {{cvt|87|PS|0}} 2.2-liter C223T turbocharged diesel engine, using a Garrett turbocharger. It was not a popular option, and Isuzu North America changed to the larger 4ZE1 four-cylinder petrol unit for 1988, then used the standard 2.8-liter GM V6 for 1989 until their own new V6 engines could be manufactured.

In 1987, the rectangular headlights were introduced, and LS trim was available for the five doors. For 1988, the 4ZD1 (2.3-liter) engine was upgraded to 110 hp, and introduced a {{cvt|120|hp|kW|0}} 2.6-liter (4ZE1) I-TEC fuel-injected engine for the US market. In 1989, an optional General Motors 2.8-liter pushrod V6 borrowed from the Chevrolet S-10 pickup was also available. Later first-generation models offered an optional four-speed automatic transmission, with 4 cylinder vehicles fitted with an Aisin A340H and V6s a GM 4L30E. Models from 1988 to 1991 were equipped with live rear axles and four-wheel disc brakes.

Overseas model engines included the inline 4 Isuzu C223 (2,238 cc), C223T (a turbocharged version of the same) and in the late 1980s naturally aspirated and turbocharged 2.8-liter I-4 4JB1 diesels. In Japan, a limited series of 100 "Bighorn Irmscher R" models was offered, which received cosmetic and interior upgrades by the German tuning house Irmscher.{{citation | url = https://www.caranddriver.com/news/a27091853/isuzu-trooper-bighorn-irmscher-r-auction/ | archive-url = https://web.archive.org/web/20230820114230/https://www.caranddriver.com/news/a27091853/isuzu-trooper-bighorn-irmscher-r-auction/ | archive-date = 2023-08-20 | first = Andrew | last = Wendler | title = Museum Quality Irmscher-R Tuned 1989 Isuzu Trooper Bighorn Sold for $22,500 | date = 2019-04-19 | work = Car and Driver }}

The turbocharged 2.8-liter originally produced {{cvt|95|PS|0}}, not much more than the {{cvt|87|PS|0}} of the considerably smaller C223T due to new stricter emissions standards. Later versions with intercoolers fitted offered as much as {{cvt|115|PS|0}}.{{cite book |title=Quattroruote: Tutte le Auto del Mondo 1990 |editor=Mastrostefano, Raffaele |publisher=Editoriale Domus S.p.A |year=1990 |pages=1255–1256 |language=it |location=Milano}}

In 1989 only, a short-wheelbase (90-inch) 2-door Isuzu Trooper was imported to the US market as the Trooper RS. All of these short wheelbase Troopers were equipped with 2.6-liter fuel-injected inline-four engines, 4.77:1 differential gears and 15×7-inch aluminium alloy "snowflake" pattern wheels. Automatic and manual transmissions were offered.

In Central America, Troopers were offered with removable roofs and a higher wheel clearance. Powertrain options included the Isuzu 2.8-liter turbo diesel. In Venezuela, the Trooper was known as Caribe 442. It was assembled locally to meet import restrictions in Venezuela; local parts content reached 35 percent by weight.

In Indonesia, where it was locally assembled by PT Garmak Motors, it was sold as the Chevrolet Trooper.{{cite web | url = https://jip.gridoto.com/read/261716197/perjalanan-chevrolet-trooper-di-indonesia-cuma-satu-generasi?page=2 | archive-url = https://web.archive.org/web/20230826205155/https://jip.gridoto.com/read/261716197/perjalanan-chevrolet-trooper-di-indonesia-cuma-satu-generasi?page=2 | archive-date = 2023-08-26 | language = id | title = Perjalanan Chevrolet Trooper di Indonesia, Cuma Satu Generasi | trans-title = The journey of the Chevrolet Trooper in Indonesia; only a single generation | date = 2019-05-12 | first = Dwi Wahyu | last = Raharjo | work = GridOto.com }}{{sfnp|Fourie|2016|p=1132}} Around 1987, a two-wheel-drive version called the Chevrolet Stallion was developed there; it has the Trooper's body on the chassis of a rear-wheel-drive Chevrolet LUV. It also has a rigid front axle instead of the Trooper's independent design. There was also a locally developed SUV model of the Isuzu Pickups built in the early 1980s called the Holden Lincah and Holden Raider. While similar to a Trooper in many ways it was a simpler vehicle and has bodywork partially made of fibreglass.

The Chevrolet Trooper name was also used in South America, except for Venezuela.{{sfnp|Fourie|2016|p=1236-1237}}

The Trooper was sold in Australia and New Zealand as the Holden Jackaroo,{{sfnp|Fourie|2016|p=1236}} named after the Australian term for a young man working on a sheep or cattle station. The standard Trooper was also sold under the Isuzu nameplate in New Zealand only.{{Cite web |title=Five not-so-fine HSVs |url=https://www.carsales.com.au/editorial/details/five-not-so-fine-hsvs-110395/ |access-date=2025-06-10 |website=carsales.com.au |language=en-AU}}

In November 1988, sales started for the Subaru Bighorn, which was only available with an Irmscher finish.{{cite web | url = https://www.yamaguchi-subaru.co.jp/archives/blog12/9071 | archive-url = https://web.archive.org/web/20220702022034/https://www.yamaguchi-subaru.co.jp/archives/blog12/9071 | archive-date = 2022-07-02 | title = 名車？迷車？ | trans-title = A famous car?

Sales were stopped in February 1992.

In November 1988, SsangYong Motors started licensed production of the Isuzu Trooper with their own bodywork and sold it as the Korando Family ({{Korean|코란도 훼미리|hanja=|rr=Kolando Hwemili}}).{{cite web | url = https://techzle.com/new-ssangyong-korando-is-nothing-like-the-one-from-25-years-ago | archive-url = https://web.archive.org/web/20230820120604/https://techzle.com/new-ssangyong-korando-is-nothing-like-the-one-from-25-years-ago | archive-date = 2023-08-20 | first = Diego | last = Meadows | date = 2022-01-23 | title = New SsangYong Korando is nothing like the one from 25 years ago | work = Techzle }}{{cite web | url = https://www.motoya.co.kr/news/articleView.html?idxno=30048 | archive-url = https://web.archive.org/web/20230826133330/https://www.motoya.co.kr/news/articleView.html?idxno=30048 | archive-date = 2023-08-26 | work = Motoya | title = [특별했던차]쌍용자동차 코란도훼미리 | trans-title = Special car: Ssangyong Motor Korando Family | language = ko | date = 2019-10-15 | last = Park | first = Byeong-ha }} A concept model known as the KR-600 had first been shown in public at the Seoul International Trade Fair in 1984, after Keohwa Motors began plans to develop it in 1982. In 1984, Keohwa was taken over by Dong-A Motors who continued development until SsangYong took over in 1987 and went on to market the Korando Family under their own name. Korando means Korea Can Do or Korea Can Do It.{{cite web | url = https://www.news2day.co.kr/article/20111226001966 | archive-url = https://web.archive.org/web/20230826133324/https://www.news2day.co.kr/article/20111226001966 | archive-date = 2023-08-26 | title = 쌍용, 대한민국 SUV의 선구자 | trans-title = SsangYong, Korea's SUV pioneer | date = 2011-12-26 | language = ko | work = news2day | last = Jeong | first = Seung-won }} Other meanings given include Korea Land Over and Korean Land Dominator.

It was only marketed in South Korea, Scandinavia, Southeast Asia, and to a lesser degree South America.

Initially, it used the Trooper's 2.2-liter diesel engine (Korean-built units being called "DC23" rather than C223), but in September 1991 the Peugeot 2.5-liter XD3P diesel engine became available. Isuzu's fuel injected 2.6-liter petrol engine was also installed, beginning in July 1991. Other changes included the addition of translucent headlamps and a chrome radiator grille. The KF had a 5-speed manual transmission.

The New Korando Family ({{Korean|뉴 코란도는 훼미리|hanja=|rr=Nyu Kolando Hwemili}}) was launched in August 1994.{{cite web | url = http://www.smotor.com/en/overview/history_1.jsp | archive-url = https://web.archive.org/web/20060517204003/http://www.smotor.com/en/overview/history_1.jsp | archive-date = 2006-05-17 | title = History: Five decades of Leadership and Innovation: 2001–2004 | publisher = SsangYong Motor Company }} All previous engine options were replaced by a 2.3-liter Mercedes-Benz OM601 diesel engine.

The SsangYong Korando ("New Korando") was launched in July 1996, replacing the KF after it debuted at the 1995 Frankfurt Motor Show.{{cite web | url = https://v.daum.net/v/LM4IwCsFNx | archive-url = https://web.archive.org/web/20231016183114/https://v.daum.net/v/LM4IwCsFNx | archive-date = 2023-10-16 | title = 특별했던차]쌍용자동차 코란도 | trans-title = Special car: Ssangyong Motors Korando | language = ko | date = 2017-11-28 | publisher = Kakao Corp. | work = Motoya }}

By 1997, around 30,000 Mekong Stars had been produced. Production ended that year as the supply of necessary parts dried up after Ssangyong changed over to producing the New Korando.

In December 1991 for the 1992 model year, Isuzu completely redesigned the Trooper to keep pace with changes in the SUV marketplace, making it larger, more powerful, and more luxurious. Originally only the long wheelbase, five-door model was on offer, but in March 1992 the shorter three-door model was added. These {{cvt|4155|lb}} vehicles used a 3.2 L {{cvt|177|PS|kW hp|0}} (SOHC) petrol engine or 3.2-liter dual overhead cam (DOHC) version rated at {{cvt|193|PS|kW hp|0}}. A SOHC 3.2-liter engine producing {{cvt|193|PS|kW hp|0}} was introduced in 1996, replacing the earlier DOHC engine in selected export markets. Most models still used a part-time four-wheel-drive system, which required stopping the vehicle to engage and disengage the front axle. Starting in the 1996 model year, some Troopers came with a "shift-on-the-fly" engagement system.

The UBS series was also available with a pushrod overhead valve (OHV) 3.1-liter inline-four engine intercooled turbo diesel (designated "4JG2") producing {{cvt|114|PS|kW hp|0}} at 3,600 rpm, and {{cvt|260|Nm|lbft|0}} at 2,000 rpm. Japanese-market diesels have a claimed maximum power of {{cvt|125|PS|kW hp|0}} and {{cvt|275|Nm|lbft|0}} of torque at the same engine speeds. It was offered as a more rugged and fuel-efficient option for towing and heavy-duty operation, relative to the standard 3.2-liter petrol. The diesel-powered Jackaroo was available with a five-speed manual transmission and manual front hubs only coupled to a part-time four-wheel drive system with open front and limited slip rear differentials. The 3.2-liter V6 petrol engine version was also available with an optional four-speed automatic transmission with automatic locking front hubs. The same diesel engine was also available in the UK and other markets with a belt-driven overhead camshaft, which developed slightly more power. After 1998, and the introduction of the "4JX1" 3.0-liter diesel engine, a four-speed automatic transmission was made available in addition to the five-speed manual transmission.

Around the same period, General Motors, Isuzu and Honda established a working relationship.{{cite web |url=https://global.honda/newsroom/worldnews/1998/4980319a.html |title=Upgrades to the Horizon Series |work=Press Release |publisher=Honda |location=Tokyo |date=19 March 1998 |access-date=30 November 2008}} Under this partnership, the Trooper was thus sold in Japan as the Honda Horizon (1994 to 1999), in Europe as the Opel Monterey, in the United Kingdom as the Vauxhall Monterey (1994{{En dash}}1998), in Australia as the Holden Jackaroo (1998{{En dash}}2002), and in the United States as the Acura SLX (1996 to 1999). The Trooper received a mid-life facelift in 1998 with new grille, bumper, headlamps, and front fenders. The rear received a body-colored, hard spare-tire cover.{{Cite web|url=https://www.motortrend.com/reviews/1998-isuzu-trooper/|title=1998 Isuzu Trooper - Motor Trend Magazine|date=February 1998}}

The 1998 Australasian and US-spec Trooper became equipped with the DOHC 3.5-liter engine from the Isuzu/Holden Rodeo producing {{cvt|215|hp|kW PS|0}}. European and Asian buyers could opt for the diesel engine option of the 4JG2 3.1-liter (later superseded by the 4JX1 3.0-liter of {{cvt|159|PS|0|disp=or}}). A Borg-Warner torque-on-demand ("TOD") all-wheel-drive system was introduced, along with freshened styling. The grille was redesigned again for the 2000 model year.

Transmission options included a five-speed manual transmission, the Aisin AR5{{cite web |url=http://onlyrepairmanuals.com/holden/holden-jackaroo |title=Holden Jackaroo Service Repair Manuals |publisher=Onlyrepairmanuals.com |access-date=28 October 2012 |archive-date=25 August 2017 |archive-url=https://web.archive.org/web/20170825023459/http://onlyrepairmanuals.com/holden/holden-jackaroo/ |url-status=dead }} and the electronically controlled 4L30E four-speed automatic. The 4L30E was fitted with both a "power" shift feature allowing the gearbox to take better advantage of the engine's power by adjusting the shifting nature and a "winter" mode permitting third gear starts for added stability in slippery conditions.{{cite web |url=http://www.unofficialbmw.com/images/BMW_Automatic_4L30E.pdf |title=Technical specifications for GM 4L30-E |access-date=27 August 2011}} The 2000 to 2002 Trooper included a feature called "Grade Logic" which allowed the transmission to automatically downshift on steep grades in order to slow the vehicle down.

The suspension consisted of a fully independent torsion bar front suspension, and a multilink coil sprung rear suspension integrated with a solid rear axle.

While US-spec Troopers came only equipped with five seats, elsewhere in the world a seven-seater version was also offered. Optional on all models was a rear limited slip differential. In the US the three-door RS model was sold only from 1993 to 1995. The Trooper LS and S models offered {{cvt|117.8|cuft|L|-1}} cargo space, while Limited models had {{cvt|112.3|cuft|L|-1}}.

In April 2004, New Zealand issued recalls for Isuzu Troopers manufactured in 1992 and 1995 due to the warning from the National Highway Traffic Safety Administration that the SUV's accelerator can stick.https://www.nzherald.co.nz/nz/isuzu-troopers-recalled-to-fix-accelerator-fault/GF5NTTXDPAY5PX2JDJCH7AOJEU/

The Acura SLX was a lightly upgraded and rebadged Isuzu Trooper sold by the Acura division of Honda from 1995 to 1999, as 1996 to 1999 year models.{{cite press release | url = https://beta.acuranews.com/en-US/releases/release-f4edc3dad3cd75874df636c4e7083501-acuras-super-rare-first-suv-reimagined-with-super-handling-all-wheel-drive | archive-url = https://web.archive.org/web/20230929125617/https://beta.acuranews.com/en-US/releases/release-f4edc3dad3cd75874df636c4e7083501-acuras-super-rare-first-suv-reimagined-with-super-handling-all-wheel-drive | archive-date = 2023-09-29 | title = Acura's Super Rare First SUV Reimagined with Super Handling All-Wheel Drive | date = 2019-12-05 | work = Acura: Newsroom }}{{cite web | url = https://hondanews.com/en-US/releases/release-6cd08e1213f4f2aca52228004c34c087-acura-model-chronology | archive-url = https://web.archive.org/web/20230927063018/https://hondanews.com/en-US/releases/release-6cd08e1213f4f2aca52228004c34c087-acura-model-chronology | archive-date = 2023-09-27 | title = Acura Model Chronology | date = November 2014 | publisher = American Honda Motor Co., Inc }} Sold only in the United States, the SLX was later replaced by the Acura MDX in 2001.

The SLX omitted some of the options available on Troopers from concurrent model years, including the manual transmission and certain engines. From 1996 to 1997 the SLX was only available with the 3.2-liter SOHC or DOHC V6 engine,{{cite press release | url = https://hondanews.com/en-US/releases/release-fca5672643f189d994de02004c34c9d6-1996-acura-slx-specifications | archive-url = https://web.archive.org/web/20230927063015/https://hondanews.com/en-US/releases/release-fca5672643f189d994de02004c34c9d6-1996-acura-slx-specifications | archive-date = 2023-09-27 | title = 1996 Acura SLX- Specifications | date = 1995-12-05 | work = Media Newsroom | publisher = American Honda Motor Co., Inc. }} switching to the new 3.5-liter DOHC V6 engine in 1998.{{cite press release | url = https://hondanews.com/en-US/releases/release-a5377968e8f2897bc43b55004c34c966-1998-acura-slx-specifications | archive-url = https://web.archive.org/web/20230927063020/https://hondanews.com/en-US/releases/release-a5377968e8f2897bc43b55004c34c966-1998-acura-slx-specificationss | archive-date = 2023-09-27 | title = 1998 Acura SLX- Specifications | date = 1997-04-29 | work = Media Newsroom | publisher = American Honda Motor Co., Inc. }} The SLX received a restyled front end for the 1998 model year, but continued to sell poorly and was ultimately discontinued after 1999. It is said that sales were affected by bad press when the 1996 to 1997 models were rated "Not Acceptable" by Consumer Reports for their tendency to roll over during testing (see Rollover Controversy, below).{{cite web | url = https://www.autoweek.com/car-life/a2156851/upgraded-acura-slx-means-yep-were-restomodding-90s-cars-now/ | archive-url = https://web.archive.org/web/20230822091850/https://www.autoweek.com/car-life/a2156851/upgraded-acura-slx-means-yep-were-restomodding-90s-cars-now/ | archive-date = 2023-08-22 | title = This Upgraded Acura SLX Means That, Yep, We’re Restomodding '90s Cars Now | work = AutoWeek | first = Graham | last = Kozak | date = 2019-12-06 | publisher = Hearst Autos, Inc.}} Autotrader says it has a 3-star safety rating (Front and Passenger) and the base entry price was $36,300.

On December 5, 2019, Acura presented a 1997 SLX outfitted with a modern turbo, four-cylinder engine, 10-speed automatic transmission and an SH-AWD system used by the RDX.{{cite magazine | url = https://www.caranddriver.com/news/a30124926/acura-slx-90s-suv-radwood/ | archive-url = https://web.archive.org/web/20211206213815/https://www.caranddriver.com/news/a30124926/acura-slx-90s-suv-radwood/ | archive-date = 2021-12-06 | title = Acura SLX, Company's First SUV, Gets Restomodded for ’90s-Themed Radwood Show | first = Clifford | last = Atiyeh | magazine = Car and Driver | date = 2019-12-05 | publisher = Hearst Autos }} It was placed on display at the Radwood show in Orange County, California.

The Australian version of the UBS-series was sold as the Holden Jackaroo/Monterey. Originally known as the Jackaroo, Holden introduced the "Monterey" as the top equipment level (V6 only) in 1994.{{cite magazine | url = https://www.tradeuniquecars.com.au/news/1709/1994-holden-jackaroo-hsv-tempter | archive-url = https://web.archive.org/web/20221104140910/https://www.tradeuniquecars.com.au/news/1709/1994-holden-jackaroo-hsv-tempter | archive-date = 2022-11-04 | title = 1994 Holden Jackaroo HSV – Today's Oddball Tempter | first = James | last = Robinson | magazine = Unique Cars magazine | publisher = Prime Creative Media | date = 2017-09-02 }} Later, Holden Monterey became a standalone name for the more luxurious part of the range. In July 1993, Holden Special Vehicles launched the sporting HSV Jackaroo model, followed by a second HSV run under the Jackaroo SE badge. 79 of the HSV Jackaroo were built, followed by 234 of the Jackaroo SE. Both were cosmetic upgrades to the Holden donor and powered by the same 3.2-liter {{cvt|177|PS|kW hp|0}} (SOHC) petrol engine. The Jackaroo SE had the HSV badging optional.

Holden issued recall orders for the Jackaroo and Monterey due to bad earthing connections within the main engine wiring harness, which would lead to an unintentional increase in speed if the engine was left idle.{{cite web | url = https://www.vehiclerecalls.gov.au/recalls/rec-000471 | archive-url = https://web.archive.org/web/20231016163308/https://www.vehiclerecalls.gov.au/recalls/rec-000471 | archive-date = 2023-10-16 | title = GM Holden Ltd - Holden Jackaroo, Monterey | id = REC-000471 | publisher = Australian Government: Department of Infrastructure, Transport, Regional Development, Communications and the Arts | work = Vehicle Recalls | date = 2011-06-06 }}

In 1996, HSV briefly explored the idea of fitting a Holden 5.0L V8 engine into both the Jackaroo and the Rodeo, but this concept was abandoned due to concerns that it would negatively impact sales of the SS Commodore. The project did not progress beyond early discussions.https://hsvjackaroo.com/blog/the-v8-hsv-jackaroo-and-rodeo-a-missed-opportunity.html

The 2001 Holden Jack8 concept was an innovative reinterpretation of the Jackaroo 4x4, created to reinvigorate interest in the aging model as it marked its twentieth anniversary in the Australian market. The concept debuted at the National 4x4 Show in Melbourne and featured dramatic modifications, including a removed roof, extended front doors, and a heavily modified rear end. The design drew inspiration from V8 desert racing rigs, with the vehicle receiving a 50mm body lift, heavy-duty suspension, and a Gen III 5.7L V8 engine.

The Jack8 was equipped with custom wheels, a reinforced roll cage, side-exit exhausts, and a range of other off-road modifications, including Mickey Thompson Baja Claw tyres and a heavy-duty suspension system. Inside, it featured Monaro-style bucket seats, a high-end audio system, and advanced GPS technology.

Although it was a running, driving concept and even registered in Victoria, the Jack8 did not significantly boost Jackaroo sales. The Jackaroo was discontinued in 2003, replaced by the Commodore-based AWD Adventra. Despite this, the Jack8 remains a symbol of Holden's design ambitions and was recently preserved in the Holden Heritage Collection.https://www.just4x4s.com.au/news-and-reviews/flashback-2001-holden-jack8-concept/892644

The Honda Horizon was retailed in Japan with either a 3.2-liter V6 gasoline engine or a 3.1-liter turbo diesel engine.{{cite press release | url = https://www.honda.co.jp/news/1994/4940210.html | archive-url = https://web.archive.org/web/20091211184630/https://www.honda.co.jp/news/1994/4940210.html | archive-date = 2009-12-11 | title = ゆとりのボディサイズと動力性能を誇るRV「ホライゾン」を発売 | trans-title = Launch of the "Horizon" RV, boasting a spacious body and powerful performance | language = ja | publisher = Honda Motor Co., Ltd. }} On March 19, 1998, the Horizon (and the Bighorn/Trooper) was updated to a direct-injection 3.0-liter engine with {{cvt|160|PS|kW|0}}, equipped for low noise and cleaner exhaust.{{cite press release | url = https://global.honda/newsroom/worldnews/1998/4980319a.html | archive-url = https://web.archive.org/web/20230821092310/https://global.honda/newsroom/worldnews/1998/4980319a.html | archive-date = 2023-08-21 | title = Upgrades to the Horizon Series | date = 1998-03-19 | publisher = Honda Motor Co., Ltd. }}

It was sold from 1994 to 1999.https://gazoo.com/catalog/maker/HONDA/HORIZON/199402/ The difference between the Horizon and the Trooper/Big Horn was the use of a 5-door body instead of a 3-door body instead of changes on the logo and grille.https://motor-fan.jp/weboption/article/132994/media/1 The grades consist of Lotus and SE.

In Europe, the Trooper/Big Horn was sold as the Opel Monterey from 1992 to 1999.{{cite web | url = https://www.autobild.de/artikel/opel-monterey-isuzu-trooper-ii-1992-2003--46909.html | archive-url = https://web.archive.org/web/20131108112922/https://www.autobild.de/artikel/opel-monterey-isuzu-trooper-ii-1992-2003--46909.html | archive-date = 2013-11-08 | title = Ein teurer Spaß | trans-title = Expensive fun | date = 2004-09-14 | work = AutoBild | language = de }} It received a light facelift for 1996, now with a honeycomb grille rather than the original design with vertical elements. Twin airbags were also new. The Monterey underwent a more thorough facelift and diesel engine changes for 1998, same as for the Trooper/Bighorn elsewhere. The Monterey nameplate lasted until 1999, after which sales were picked up by Isuzu's dealership network as the Trooper.{{cite press release | url = https://www.media.stellantis.com/em-en/opel/press/30th-birthday-opel-monterey-the-off-roader-for-discerning-buyers | archive-url = https://web.archive.org/web/20231016195434/https://www.media.stellantis.com/em-en/opel/press/30th-birthday-opel-monterey-the-off-roader-for-discerning-buyers | archive-date = 2023-10-16 | title = 30th Birthday Opel Monterey: The Off-Roader for Discerning Buyers | work = Opel Heritage | publisher = Stellantis | date = 2022-06-02 }} The Trooper remained on sale in Europe until 2003.

From 1994 to 1998, the Trooper/Big Horn was sold in the UK as the Vauxhall Monterey, but with no other changes.{{cite web | url = https://www.hagerty.co.uk/articles/automotive-history/cars-that-time-forgot-vauxhall-monterey/ | archive-url = https://web.archive.org/web/20221107141102/https://www.hagerty.co.uk/articles/automotive-history/cars-that-time-forgot-vauxhall-monterey/ | archive-date = 2022-11-07 | title = Cars That Time Forgot: Vauxhall Monterey | first = Richard | last = Dredge | work = Hagerty UK | publisher = The Hagerty Group, LLC | date = 2022-11-07 }} However, it was not a strong seller and was withdrawn from sale a year before the Opel version.

In 1992, Subaru sold the Subaru Bighorn with a 3.2-liter V6 gasoline engine and a 3.1-liter, inline-four cylinder turbodiesel engine made available with a four-speed automatic or five-speed manual transmission.{{cite web | url = https://ucar.subaru.jp/php/catalog/model.php?car_cd=10452501&getyear=199202 | archive-url = https://web.archive.org/web/20230926181150/https://ucar.subaru.jp/php/catalog/model.php?car_cd=10452501&getyear=199202 | archive-date = 2023-09-26 | title = 発売モデル ビッグホーンのモデル一覧: 1992年2月 | trans-title = Bighorn model list: February 1992 | work = SUGDAS | publisher = Subaru Corporation | language = ja }} In mid-1994, Subaru discontinued further sales since the OEM contract signed by Subaru and Isuzu was expiring. The only model available was the "Long Handling by Lotus", with either a four-speed automatic transmission or a five-speed manual (turbodiesel only). Subaru reported the transmission was worked on with the assistance of Lotus.{{cite web | url = https://www.automesseweb.jp/2017/12/25/37667 | archive-url = https://web.archive.org/web/20231016153501/https://www.automesseweb.jp/2017/12/25/37667 | archive-date = 2023-10-16 | title = SUBARUでも販売された悲劇のOEMモデル「ビッグホーン」 | trans-title = The tragic tale of Subaru's OEM deal to also sell the Bighorn | first = Shinya | last = Yamamoto | work = Auto Messe Web | publisher = Kotsu Times Sha Co., Ltd. | date = 2017-12-25 }}

The second-generation Trooper received negative press in the United States when the 1995–1997 models were rated "Not Acceptable" by Consumer Reports for an alleged tendency to roll over under testing.{{cite news |url=https://www.latimes.com/archives/la-xpm-1997-jul-26-mn-16538-story.html |work=Los Angeles Times |date=26 July 1997 |title=Agency Finds Isuzu Trooper Defect-Free}}

In response to a petition from the publication's publisher, Consumers Union, the National Highway Traffic Administration conducted its own tests and found no issue that could lead to a need for a recall. However, Isuzu suggested that the magazine's claims had hurt sales of the vehicle.{{cite news |work=St. Petersburg Times |date=3 November 1996 |title=Trooper report trips up sale |page=6H}}

After the release of the NHTSA report, Isuzu filed a lawsuit against Consumers Union seeking $242 million in damages, claiming that during Consumer Reports's tests the steering wheel had been twisted more sharply than "a driver is willing or able to make in response to an unexpected event.{{cite news |work=The Daily Courier |date=1 August 1997 |title=Isuzu sues Consumers Union over report on Trooper |page=2A}}

The judge in the suit, Richard Paez, determined that because Isuzu had engaged in an extensive public relations campaign to refute the claims prior to filing suit, it was considered a public figure, raising the standard for defamation from a simple preponderance of evidence that the report was false to "clear and convincing evidence" that Consumer Reports published the article knowing it was false or with reckless disregard for whether it was true or false.{{cite news |url=https://www.washingtonpost.com/wp-srv/WPcap/2000-02/09/042r-020900-idx.html |title=Consumer Reports Defamation Trial Starts |newspaper=The Washington Post |date=9 February 2000}}

The defamation suit went to a jury, which found that eight of the 17 statements in the report questioned by Isuzu were false, with one displaying "reckless disregard" for the truth on the part of Consumer Reports magazine, but that Isuzu was not damaged by that statement.{{cite news |work=Daily Union |date=7 April 2000 |title=Jury clears Consumers Union |page=3}}{{cite news |url=https://www.nytimes.com/2000/04/07/business/isuzu-is-denied-damages-in-a-lawsuit-against-consumer-reports.html |work=The New York Times |first=Andrew |last=Pollack |title=Isuzu Is Denied Damages in a Lawsuit Against Consumer Reports |date=7 April 2000}} Two of the ten jurors on the panel did not believe the magazine believed that the other seven statements were untruthful when they published them. Consequently, the full jury panel did not award Isuzu monetary damages for the alleged damage to its reputation and lost sales.

Isuzu calculated the total cost of the Consumer Reports claims at $244 million.{{cite web |first1=Dee-Ann | last1 = Durbin | first2 = Tom | last2 = Krisher |url=http://www.projo.com/projocars/content/ca_isuzuout_02-02-08_OG8RD1F_v6.1f10cef.html |title=Isuzu to stop selling new vehicles in North America |publisher=projo.com |date=2 February 2008 |access-date=27 August 2011}} As Isuzu was denied damages on all counts, the formal court judgement in favor of Consumers Union entered by Paez required Isuzu to pay CU's "reasonable costs" of defending itself against the suit, not including attorney's fees.{{cite web |url=http://www.allbusiness.com/legal/trial-procedure-judges/6479006-1.html |title=Business solutions from AllBusiness-Redesign |publisher=AllBusiness.com |access-date=27 August 2011}}
