The active body control system can leak fluid from numerous areas, including the tandem pump, hydraulic lines, struts, and/or seals. If it is not repaired, the vehicle ride height could drop too low and cause damage to the undercarriage.

The door for the vanity mirror (or the frame for the door) can break; due to a redesign, the mirror "cassette" will need replacement.

The center console armrest can break. Replacement is commonly the recommended repair.

 

The ESP and BAS warning lights may illuminate due to a failed brake light switch. Replacement of the failed switch should correct this concern.

The crankshaft position sensor may fail. Symptoms of this are: The engine will crank—but not start—especially when the engine is warm. The car may start again if it is left to cool off, but it may run roughly or have poor performance.

Leaks may develop from the differential cover and/or seals on high mileage or older vehicles. Our technicians recommend a complete reseal of the differential unit if these leaks are addressed.

A vibration felt through the center floor of the vehicle can be caused by driveshaft flex discs, which crack and shred, causing excessive driveshaft movement. Not repairing these can cause damage to the driveshaft center support bearing, or, in the worst case scenario, damage to the transmission or differential.

A door control module/actuator may fail. Our technicians recommend finding an expert to repair them. Taking the door trim panels off requires expert knowledge because they can break and the pieces are very expensive.

CD changers, command units, voice control units, PSE units, and Tele Aid units are prone to failure, especially in early models.

An engine oil leak may develop from the oil level sensor. Replacement of the leaking sensor will commonly correct this concern.

The anti-lock brake system (ABS) modulator assembly may fail due to dirty brake fluid. Our technicians recommend a complete brake system flush every two years in order to help prevent this problem.

The evaporator temperature sensor can fail, causing the AC compressor not to cycle. If the AC compressor does not turn on, the AC system will not blow cold air. If the compressor is stuck on, the air will be very cold at first, before warming up.

Due to the size and material used on the brakes of these vehicles, the brakes may start to squeak around the 50 percent wear point. The brake rotor surfaces become uneven, causing a lip to form at the outer edge of the rotor. Because of this, the rotors are usually replaced when the pads are worn (pad life varies depending on driving style and terrain).

Due to wear of mechanical parts in the control head, the buttons on temperature control assemblies work erratically or not at all. These control heads need to be replaced for this concern or when the display screen starts to fade out.
Cup holders break easily, especially if sticky liquids are spilled into the cup holder mechanism.
