RepairPal has identified the most common problems with the Isuzu as reported by actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.Refine by vehicle
The fuel level sensor may fail resulting in erratic fuel gauge operation and illumination of the Check Engine Light. Replacement of the fuel sender assembly is recommended to correct this concern. A powertrain control module (PCM) software update may be necessary for the updated fuel level sensor to read correctly.
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 check transmission light may illuminate with a stored code 37. This is commonly caused by electrical interference on the data communication circuit between the transmission control module (TCM) and the engine control module (ECM). Our technicians recommend that all related connection and ground locations should be inspected and repaired as necessary. In some cases electromagnetic interference may be the cause, shielding of the affected wiring may be of help it this case.
The fuel level sensor may fail resulting in erratic reading of the fuel gauge. Sensor replacement is generally required to correct this concern.
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.
On some models the powertrain control module (PCM) software delays idle speed changes during cold starts causing stalling problems. A software update is available to repair this issue.
On some models the rear wire harness for the Anti-lock brake system (ABS) can fatigue and break causing the ABS light to come on. Replacing the harness with a new updated harness should repair this problem.
The automatic transmission accumulator cover can leak due to a failed o-ring. Replacing the o-ring and cover will commonly correct this issue.
A worn vehicle speed sensor driven gear can cause the speedometer not to work. Replacing the worn out speed sensor should correct this concern.
