Known Problems
Front thrust arm and control arm bushings can crack and sometimes tear completely. If this is not repaired quickly, damage to the front subframe unit will occur, which is very expensive to repair. Updated control arms (that prevent damage to the subframe when the bushings wear out) are available.
Oil can leak through the seal on the oil sensor or from the sensor itself. The lower oil pan must be removed and the part replaced.

Analog Tele Aid units are no longer supported and must be updated to digital, preferably at a dealership or a well-equipped independent shop. The update and all related factors should be completed at the same time.

The climate control system can fail or perform erratically due to internal problems with the climate control button electrical contacts. Replacement of the climate control assembly is commonly required to correct this problem.

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

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

Window seals tend to develop leaks.
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.
