Summary
The Isuzu Trooper has 9 recalls spanning 1986 through 2000, with the most serious recent issue affecting 2000 model year vehicles equipped with 4WD and torque-on-demand automatic transmission, where high-speed frontal crashes can cause the fuel hose to separate or sever and leak fuel.
Several recalls cover powertrain and drivetrain integrity across the later production years. On 1998 models with the Torque-On-Demand 4WD system, the transfer case output flange lock nuts may not have been properly staked at the factory, allowing them to loosen and cause the propeller shaft to separate from the vehicle while driving. The 1997 model year has a front hub bearing concern where missing lock washers or screws can allow the hub and knuckle to work loose, leading to bearing seizure and potential loss of wheel control. On 1996 models, a brake line routed too close to the upper front control arm can chafe and crack during normal operation, leaking brake fluid and lengthening stopping distances. Also on 1996 vehicles, the rear center seat belt buckle was built with an incorrect part that physically cannot accept the latch plate, leaving that seating position without a functioning restraint.
Going back to 1992, two separate issues affect the 3.2-litre engine. Camshaft end plugs can dislodge from the cylinder heads, causing rapid oil loss onto the exhaust system and raising the risk of an engine fire. Separately, the accelerator cable cover can deteriorate after years of use, causing the cable to stick to its boot and delay throttle closure by several seconds after the pedal is released. On 1990 models with the V6 engine and automatic transmission, an unlocked transmission dipstick can vibrate loose and allow fluid to drip onto the exhaust manifold, also creating a fire risk. The earliest production covered by these recalls is the 1986 model year, where corrosion on the tailgate hinge pins can create a false-latch condition, making the tailgate appear closed when it is not and allowing it to swing open without warning, with passengers or cargo falling out.
