The brake pedal slowly goes down . The consumer also stated that the pump motor keeps running that and injection system throttle control sticks at idle. The dealer bled the master cylinder and everything seems fine. *scc

Service brakes, hydraulic: foundation components: disc: rotor
- What is wrong
- Vehicle description: passenger and multi-purpose vehicles originally sold or currently registered in the states of connecticut, illinois, indiana, maine, maryland, massachusetts, michigan, new hampshire, new jersey, new york, ohio, pennsylvania, rhode island, vermont, or wisconsin, and the district of columbia. The front disc brake rotors can experience severe corrosion if operated for an extensive period in the "salt belt." if the rotors are not replaced, the corrosion can eventually compromise the structural integrity of the stamped steel center hub section of the rotor.
- Risk
- The reduced strength can allow the cast iron wear surface to separate from the hub, reducing the brake effectiveness of the vehicle.
- Remedy
- Dealers will replace these rotors with rotors that are coated with a corrosion protection.

What 1990 Jeep Comanche owners say
Most recent owner complaints, unedited.
Vehicle started and excelerated and caused a lineup of crashes.update on throttle could have minimized or prevented, but hearing the problems others have had and considering not updating. First five years vehicles brakes and exhaust were sorry. Have replaced all with after-market stuff and all problems have stopped. Jeep should consider better equipment, especially because trucks generally are used to pull trailers such as me. Still want my parking brake fixed. I would like a reliable hand brake as in some models.
5spd wont hold truck&trailer on steep launch ramp.parking brake disengages.dealers don't know how to fix recurring problem.I've asked for hand brake but they say the can't convert from foot to hand brake. Had truck for 10 years and this is my main buyer's remorse. I'll never consider another vehicle with a foot parking brake again.cab did pay small visit to the drink due to junky parking brake.this needs to be resolved once and for all.
Seat belt will not latch intermittently and also comes unlatched while driving. Nlm
The throttle position sensor is not functioning properly in my jeep. I found that tere are 3 service bullitens requireing the replacement of the same. There is also one recall indicating the part should be replaced. I called up jeep (chrysler) they said that the recall does not apply to my jeep. It was made during the months listed in the recall and the serial number on the sensor applies the the list in the servoce bulletins. I initiated a case with chrysler the complaint # is 55441434. Please clarify this issue if you can asap. The jeep is dangerous to operate, because of this malfunctioing sensor.
Brake lines let go. When the brakes were applied, nothing happened. All of the brake lines are rusted out, no other rust on the vehicle. Dealer contacted and will inspect the vehicle.
Paint peeling.
Emergency brake cable system failed, due to rust and corrosion.
Gas tank: driving down freeway and heard a noise, pulled over and the gas tank was hitting against the driveshaft. Bolt that holds the strap had come out of slots.
The transmission some time it will not shift into gear . Tt
