Trouble Spots

Consumer Guide's® Auto Editors have scoured repair bulletins and questioned mechanics to search for commonly occurring problems for a particular vehicle. In some cases we also give possible manufacturer-suggested solutions. In many instances these trouble spots are Technical Service Bulletins posted by the manufacturer, however, we have our own expert looking at additional vehicle problems.

Audio system: The company is replacing radios that have poor AM reception or FM bleed into the AM band. (1998-99)

Brake noise: The front brakes make noises (squeals, grinding, groaning, etc.) requiring new brake pads and redesigned rotors. (1998)

Engine knock: The engine makes ticking noises and knocking noises that sound like main bearing knock, often due to cylinder carbon buildup. (1998-99)

Engine knock: Engine knock, especially when cold, may be due to carbon buildup in combustion chambers. (2000-01)

Engine temperature: Overheating and coolant loss may be due to rough surface on radiator filler neck. Neck should be sanded smooth and cap replaced. (1999-2000)

Fuel gauge: The fuel gauge reads empty or swings between empty and full due to problem with the in-tank sending unit. (1998)

Oil leak: Beware rear main seal leaks on Northstar engine. (1996-99)

Paint/body: On white cars, the door handles turn yellow from the lock cylinder grease staining them. The company will replace the cylinders under warranty and there is a colorless grease available for service. (1998-99)

Poor transmission shift: Transmission is slow to engage between drive and reverse, often accompanied by a clunk requiring a transmission rebuild under warranty. (1998)
