During the warranty period, several defects were repaired, including the water pump and the stereo.
The shift knob has been replaced five times. It's a common defect, and a "cash cow" for Chrysler!
The ignition has been replaced twice. The ignition key tends to file itself down over time, with associated wear on the ignition.
The driver's side window cannot be fully rolled down without jamming part way down. It's still operable, but requires a two-handed tug-of-war, something that's undesirable while driving.
The door locks are notoriously ineffective, and fall apart easily. I've had to replace the driver's side lock twice. I've given up on the passenger side lock.
After a couple of years, the clearcoat started turning milky white in ever-growing patches, and has been gradually flaking off ever since. This is a common problem with Cherokees from about 1987-90.
The stereo, which was an expensive option, self-destructed completely after a couple of years of erratic performance.
The driver's seat belt latch became inoperable, requiring replacement.
The crankshaft position sensor stopped working correctly, making it difficult to start the vehicle. Interestingly, it finally failed completely while I was in the parking lot of a Canadian Tire store, so I was able to get it fixed on the spot.
The heater motor wore out, causing a fuse in the resistor pack to blow, necessitating replacement of both. If a Cherokee will only blow air on the "high" setting, the resistor pack fuse is probably blown. It's a common problem, and an easy forty dollar repair.
One of the fuel injectors started leaking gasoline, requiring replacement of the injector and new "O" rings for all the injectors.
About ten years ago, the engine block heater blew right out of the block, causing the coolant to leak out and the engine to overheat. There was no serious damage, however. The engine has been fine ever since.
The rear bumper had to be replaced due to corrosion of the mounting brackets.
The power-steering pump required rebuilding.
Routine maintenance has required regular replacement of tires (on fourth set), brakes (on third set), exhaust (on third exhaust system), catalytic converter (replaced once), oxygen sensor (replaced once),spark plugs (replaced twice), hatch struts (replaced once), water pump (replaced once), the clutch (replaced once due to the throwout bearing wearing out), the clutch master cylinder (replaced once), headlights and other assorted bulbs (including instrument lights), shock absorbers (replaced once), front wheel bearings (replaced once), rear axle seals (replaced once), serpentine belt (replaced twice).
This may seem like a lot of repairs, but I've had the vehicle for almost eighteen years, and subjected it to hard use on a daily basis as my main vehicle.
