1999 Isuzu Trooper Problems
RepairPal has identified the most common problems with the 1999 Isuzu Trooper based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
Lack of oil changes can cause the piston rings to become clogged with debris resulting in excess oil consumption. Severe engine damage may result if the oil level gets to low. Engine dis-assembly may be required to clean or replace the piston rings. Our technicians recommend proper maintenance to try and avoid this expensive repair.
A ticking noise may be noted from the engine valve train area. This is commonly caused by varnish build up in the hydraulic lash adjusters (HLA). Our technicians tell us that using Mobil 1 synthetic oil has been successful in cleaning the varnish deposits and quieting the lifter noise.
The fuel level sensor may fail causing erratic operation of the fuel gauge. Our technicians tell us that replacement of the failed sensor is necessary to correct this concern.
