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.

Air conditioner: A lack of cooling is caused by the A/C evaporator freezing up because the compressor does not cycle off. (1991-93)

Engine noise: Piston slap requires replacement pistons and rods on 3.3- and 3.8-liter engines. (1990-93)

Engine noise: A chirping noise from the serpentine belt, especially in wet weather, is corrected by a replacement automatic belt tensioner. (1991-93)

Suspension noise: Sway bar bushing wear causes a squeaking noise from the front suspension. (1992-93)

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 Landau Salon: On cars with gray interior, airbag inflator modules may not contain diffuser holes between igniter and propellant chambers, so airbag would not deploy in an impact.

1990-91: On cars without automatic temperature control, water leakage under windshield cowl may result in corrosion of heater blower resistor terminals, which could lead to overheating and possible ignition of wiring connectors and insulation, causing a fire in cowl area.

1990-93 w/ABS: Antilock braking could fail, and power assist might be reduced.

1991 Salon: Front disc brake caliper guide pin bolts may not be adequately tightened and could loosen, which could cause reduced braking effectiveness that might result in accident.

1991: Front-outboard seatbelt may become difficult to latch and/or unlatch.

1992: Zinc plating of some upper steering column shaft coupling bolts caused hydrogen embrittlement and breakage of the bolt, which could result in loss of steering control.
