  • 152,000 miles


The engine has 150,00 miles. It is losing coolant with no puddles to show for it. The oil pressure gauge shows 0 at idle. The engine constantly overheats. No sign of head gasket leak. Coolant overflow tank fills with coolant/oil/rust mixture after running the engine for 5 minutes. Door locks don't work sometimes. Tail lights work on and off while the lights are off. All problems started within the last year.

Cherokee 6-cyl

  • 58,000 miles
First, engine began to loose overheat and loose coolant at 55,000M - 1 qt every 200 - 300 miles. No leak found by mechanic. Loss continued. Then loss of oil pressure when engine was warmed fully. Pressure drops at all RPM but down to 0 when idle is below 1300 RPM( (at idle). Cannot find leak but have been advised on several forums that this year (98 - 01) Jeep 4.0 engines have a very high failure rate related to this problem. The problem appears to be a faulty engine casting prone to internal cracking, causing coolant loss and loss of oil pressure. Jeep dealer denies and knowledge of this issue. But, Jeep sent a special letter to buyers of this year/model Jeep Cherokee that they were desperate to buy as many of this year make/model as they could and would provide a reasonable trade-in value. They did not specify why they would need to acquire so many of this particular used year/model Jeep Cherokee.

  • Automatic transmission

Consumer states front rotors continue to warp after (2) replacements. When ever the truck hits a bump while traveling 50 mph or above will shake violently. Owner is concerned about controlling the truck when this happens. Also the upper and lower ball joint was loose which was causing the steering wheel to shake, the transfer case was loose, the gasket and thermostat was replaced due to a coolant leak, cruise control was inoperative, the air condition and heater only blows at defrost vents, the rear luggage rail came out.
