Two problems related to loud engine noise have been reported for the 1996 Jeep Grand Cherokee. The most recently reported issues are listed below.
Exited off freeway, slowed down to merge into traffic. Went over a manhole cover (not a big bump, normal manhole cover) heard noise like the tires picked up a stone. Drove 1/2 block and heard a rubbing noise, decided to take vehicle to dealer since it was only a couple of blocks away. Dealer said that the bolts on the right side motor mounts sheared off and motor was hanging. Dealer said that this is not covered by mfg and that it was considered normal wear. I feel this is a safety problem, I have never had a motor mount break and leave an engine hanging, I have never had a motor mount break at 47,000 miles. Vehicle has never been taken off road, has never been driven on gravel - it is a very pampered Jeep! is there any recall or safety regulations on something like this?.
Mounting bolts that hold motor in engine sheared off onto ground, causing motor to drop, only indication was loud noise, bolts were not properly tightened, dealer replaced bolts.
