A guide to problems, costs, maintenance and repair for your 2003 Jeep Grand Cherokee

The best method to reduce pulsations is to use an "On the Car" brake lathe (as long as the rotors are suitable for turning). "On the Car" equipment can correct variations (or "runout") in the rotor surfaces because it also corrects variations in other components (e.g. the hub).

As a result the front airbags, side airbags, and/or seatbelt pretensioners could deploy inadvertently while the vehicle is being operated, increasing the risk of personal injury and/or a crash. Dealers will replace the airbag control module and front and/or side impact sensors as required to correct this concern.

A component in the air bag control module may fail causing the front airbags, side curtain airbags, and/or seatbelt pretensioners to deploy inadvertently while the vehicle is being operated. Inadvertent deployment of the airbags may increase the risk of injury and the possibility of a vehicle crash.

Good solid vehicle.

I have a 2003 Gran erokee Jeep @ 143,000 miles. I took my car into the shop and they think it needs an ignition coul or a computer. The car is running rough. It starts but when it gets warm it cuts off. If changed from park to reverse it will cut off.
