Three problems related to manifold/header/muffler/tail pipe have been reported for the 1999 Jeep Grand Cherokee. The most recently reported issues are listed below.
: the contact stated the oil gauge failed to indicate the oil level; the front end vibrated badly at 50 mph, and the wheels shook and made a clicking sound while making a turn in either direction, which caused a vibration felt through the steering wheel. In addition, black smoke discharged from the tail pipe and the engine emitted a hesitation. When inspected by an independent mechanic, oil and gas were visible on the spark plugs. The service dealer and manufacturer were notified.
On December 7, 2002 my family and I (including my 2 1/2 year old daughter) were driving down the new jersey turnpike and our 1999 Jeep Grand Cherokee caught fire. A state trooper aided us in putting the fire out and we had the vehicle towed off of the interstate. Upon our return home that evening we discovered a daimler Chrysler recall notice (recall: b06) in the mail stating that a defect in the exhaust manifold may result in and underhood fire. Daimler Chrysler has since informed us that because the vehicle is over 3 years old they will not reimburse us for the costs of repair or provide an explanation as to how or why the fire ocurred.
Exhaust manifold gasket over heated and burned up in turn had caused over heating in the torque converter. This led to transmission failure. Keyless entry lock had malfunction also.
