1999 Jeep Grand Cherokee Laredo has had numerous problems with the fan clutch assembly. Symptoms include loud noises from the engine compartment from startup until a few miles are driven, almost like that of a loud airplane. Vehicle has approximately 155,000 miles and has been one owner since new. Fan clutch assembly has failed more than four times at this point, requiring the replacement of the fan clutch assembly on each failure. One repair was completed at a Jeep dealership under the factory warranty; a second repair was made also at a Jeep dealership outside the factory warranty at a cost of over $350. Third and fourth replacements of the fan clutch were made using genuine new mopar/Jeep parts, but not at a dealership location at a cost of just under $300. Now the dealership has diagnosed this fault for a fifth time, with an estimated replacement cost of $350. It seems abnormal to have to replace the fan clutch assembly every 30,000 or so miles, and that the manufacturer of these units may have a faulty design.

Crankshaft counter balance weights scraping against internal engine block due to main crankshaft thrust bearing wearing out at 115,000 miles due to bad oem part. All other engine parts are excellent! this wear causes an internal ticking sound that steadily gets louder as wear continues. Replacement of the thrust bearing requires engine removal, engine disassembly and is not practical. After $900 for diagnostic work, mechanic says put it back together and drive it until it stops, then replace the entire engine.............or replace it now........the part will fail and be terminal to the engine.

Consumer complained about a transfer case problem. When driving at approximately 40 mph there was a loud clanking sound coming from the front undercarriage. Consumer took the vehicle back to the dealer, and was told the vehicle had dusty brake pads, but that was not the issue. Then, consumer was told that the constant velocity joints were leaking. Also, consumer was told that the driveshaft needed to be replaced. Consumer felt that the dealership did not know what the problem was, and perhaps was covering up the real problem. Recall campaign; component: Fuel system, gasoline:fuel injection system:injectors. The consumer stated that the vehicle would not start. The consumer stated that the engine had an extended crank before starting. Fuel pump assembly and pump crank repair kit installed. The consumer stated that there is a shimmy when the brakes are applied. When sitting at a stop light having the vehicle in gear it vibrates. The left outer cv boot was leaking. The engine light came on. The consumer stated that the transmission slams into gear.

My wife made a quick stop at a local store. Upon returning the vehicle's engine would not turn over. She paused for a few minutes and attempted to start the engine again. There was a loud bang followed by a loud rattling. At the mechanic shop, the mechanic hoisted the Jeep on the lift and we witnessed a hole and crack in the bottom of the engine about the size of a softball. The cracked piece was only being held by a bolt or some kind of rivet or else the hole damage would have been much larger. The 99 Jeep gc had 96500 miles on it, regular oil changes, and it was not leaking oil. It happened without warning, and I have heard no decent explaination for this. Cost $1500, and this was considered a good price. Yours truly, disgrunted consumer

Broken window motor, seat belt mounting bolts, leaking rear shock absorbers, etc... the consumer felt Jeep should fix the outstanding problems with the axles and the transmission and give a warranty for the power train. The vehicle experienced a noise while in motion. Also the broken window lift leaked, the rear absorbers failed, the rear passenger window leaked air, the seat belt mounting bolts failed, and a potential fire hazard on the manifold debris shield, the brake pedal pulsated wildly(front were rotors turned), the passenger window had stuck shut, the exterior mirror had broken off, and the transmission slammed into reverse. There was a buzz in the rear which had progressed to a howl. Refer to ODI# 10027025
