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.

Automatic transmission: 4T60E transmissions may drop out of drive while cruising, shift erratically, have no third or fourth gear, or no second and third 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. (1991-94)

Dashboard lights: The Enhanced Traction Control (ETC) warning light "ETC OFF" may glow and the cruise control stop working. No current fix. (1996)

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: Bearing knock was common on many 3.3-liter engines due to too much clearance on the number-one main bearing. (1992-93)

Engine noise: A rattling noise from the engine that lasts less than a minute when the car is started is often caused by automatic transmission-pump starvation or cavitation, or a sticking pressure-regulator valve. (1994-95)

Engine noise: Ticking on cold startup may be due to excessive piston pin to bore clearance. (1994-97)

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)

Transaxle leak: The right front-axle seal at the automatic transaxle is prone to leak and 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)

This table lists costs of likely repairs for comparison with other vehicles. The dollar amount includes the cost of the part(s) and labor (based on $50 per hour) for the typical repair without extras or add-ons. Like the pricing information, replacement costs can vary widely depending on region. Expect charges at a new-car dealership to be slightly higher.

1994: Welds in rear assembly of fuel tank may be insufficient to prevent leakage in certain rear-impact collisions, increasing risk of fire.

1996: During deployment of the passenger airbag, the airbag can snag on a reinforcement inside the instrument panel. This might cause the airbag to not deploy properly.

1996: Front and/or rear hazard warning lamps might not work.

1996: If the key is held in the "start" position for an extended period, high current flowing through the ignition switch can melt internal switch parts.

1996: Interior lamps might come on unexpectedly while vehicle is being driven.

1997: Omitted fuse cover could result in short circuit and possible fire.
