1989 Jeep comanche common problems

The most-reported problem areas across all 12 owner complaints filed with NHTSA — and what to check before you buy.

Tires
Check tread depth, the DOT age date, and that all four tires match with even wear. Look for bulges or cracks.
Power Train
Drive through every gear: watch for slipping, hard or delayed shifts, and shudder. Check for transmission/driveline leaks and noises.
Steering
Steering should be tight and centered — no play, clunks or wandering. Test at low and highway speed; listen for power-steering whine.
Vehicle Speed Control
Test cruise control and throttle response, and watch for any hesitation or unintended acceleration.
Engine And Engine Cooling
Check coolant level and color, look for leaks, and confirm the engine reaches normal temperature without overheating.
Equipment
Test all accessories — sunroof, climate, seats, electronics — for proper operation.
