Four problems related to engine exhaust system have been reported for the 1998 Jeep Grand Cherokee. The most recently reported issues are listed below.
While driving, heard constant noise. Took vehicle to dealer for service who stated that exhaust manifold needed to be replaced. The exhaust manifold cracks gradually and is noticeable when the vehicle is cold. Any air leak in the firewall allows exhaust fumes to enter the vehicle.
All of the problems identified in my complaints are covered by Chrysler extended warranty. But I strongly feel Jeep is building an inferior and unsafe product which can cause serious accidents. The most notables were the (2) auto transmissions failure at freeway speed. The transmissions had to be replaced and the replacement unit was installed with a defective pump which also went out. The most recent incident is with the engine and all electrical system shuts off at freeway speed with no warning. The explaination given was a weak battery and loose battery cable. All other incidents are due to sub-standard Jeep oem parts. I wish my complaint will force Jeep to investigate why a Jeep Grand Cherokee 5. 9 limited, their flagship, would failed time after time at such a young mileage. Thank you.
Exhaust system problems, causing fumes to enter into vehicle, dealership has inspected vehicle on four occasions and can not determine failure. Mjs.
Intermittently the vehicle would vibrate while applying the brakes. The brake pedal would go to the floor and cause an extended stopping distance. Dealer is aware of the problem. Mr there is an exhaust type of noise emitting from the vehicle.
