Problems for specific Isuzu Rodeo years:

Certain models may have a vibration issue at highway speeds that could be due to uneven tire pressures, tire rim out of specs, wheels out of balance, AC compressor bracket bolts not torqued correctly, misalignment of the steering shaft coupler, improper ride height, or wheel alignment out of adjustment. A qualified technician is needed to sort out these problems and correct them.
The automatic transmission accumulator cover can leak due to a failed o-ring. Replacing the o-ring and cover will commonly correct this issue.
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 certain models contamination of the grease on the gas pedal potentiometer causes the Check Engine light (MIL) to come on and may cause a rough idle. The potentiometer will need to be replaced and adjusted to fix this problem.
Rear axle seal leaks can be cause by a plugged rear differential vent. Replacing the leaking seal and clearing out the vent will fix this problem.
On some models, the right motor mount cover may touch the chassis and cause a vibration at idle. Replacing the motor mount will repair this issue.
Chattering when cornering can occur when the limited slip differential fluid breaks down. Replacing the fluid will repair this issue.
