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.

Climate control: On cars with automatic temperature control, the blower may blow cold air when the temperature is below 20 degrees (F) until the engine warms up. A new powertrain control module is required. (1991-92)

Engine misfire: Cars with the 3.0-liter engine may sag or pop under hard acceleration, then surge between 30-40 mph when warm. The fix is to replace the engine control computer. (1991-92)

Engine misfire: Trouble with the fuel pump may cause the pressure to fluctuate, which results in loss of power. (1991-92)

Hard starting: The engine may not start due to a lack of compression caused by bad rocker arm assemblies. (1990-92)

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.

1990-92: Automatic shoulder belt systems can become inoperative.

1990-92: Coolant from heater could escape into passenger compartment.
