1992-1998 Pontiac Grand Am: Reliability
Trouble SpotsConsumer Guide'sŪ 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.
Automatic transmission: 4T60E transmissions may drop out of drive while cruising; shift erratically; or have no second, third, or fourth gear because of a bad ground connection for the shift solenoids. (1994)
Automatic transmission: TH-125 automatic transmissions may shift late or not upshift at all. The problem is a stuck throttle valve inside the transmission. (1992-94)
Engine noise: A tick or rattle when the engine is started cold may be due to too much wrist-pin-to-piston clearance. (1994-95)
Engine noise: Ticking on cold startup may be due to excessive piston pin to bore clearance. (1994-98)
Engine noise: Bearing knock was common on many 3.3-liter engines due to too much clearance on the No. 1 main bearing. (1992-93)
Engine noise: A rattling noise from the engine when the car is started after sitting is often caused by automatic-transmission pump starvation or a sticking pressure-regulator valve. (1994-95)
Engine temperature: Overheating and coolant loss may be due to rough surface on radiator filler neck. Neck should be sanded smooth and cap replaced. (1998)
Ignition switch: The ignition switch may not return from the start to the run position and the accessories such as the radio, wipers, cruise control, power windows, rear defroster, or heater may not work because the screws that hold the switch in place were overtightened. (1992-94)
Radiator: Some cars mysteriously lose coolant. The common problem is a bad seal on the pressure cap on the surge tank that is connected to the radiator. (1992-94)
Traction control indicator light: The ETC warning light "ETC OFF" may glow and the cruise control stops working. If the computer failure memory is cleared, everything returns to normal. No current fix. (1996)
Transaxle leak: The right front-axle seal at the automatic transaxle is prone to leak. GM issued a revised seal to correct the problem. (1992-94)
Valve cover leaks: The plastic valve covers on the 3.1-liter engine were prone to leaks and should be replaced with redesigned aluminum valve covers. (1994-95)
