Windshield Wiper Failure

The windshield wiper system, particularly the wiper module motor, can fail due to corrosion. This leads to loss of wiper function, severely compromising visibility in adverse weather conditions. Estimated repair cost: $300 - $700.

While less frequent than engine oil consumption, power train complaints can include transmission performance issues, such as rough shifting or slipping. These can be exacerbated by neglected fluid maintenance. Estimated repair cost: $500 - $2,500.

Electrical System Glitches

Various electrical system complaints are noted, ranging from minor accessory malfunctions to more concerning issues that could impact drivability. These can be difficult to diagnose without proper tools. Estimated repair cost: $100 - $500.
