- Summary
- Some customers may experience improper operation of the rear parking system with beep sounds coming from the rear parking sensor when there are no obstacles behind the vehicle. This occurs when the blower fan is on (at any fan speed) and the transmission is in "R" position. The concern is caused by electrical noise from the blower fan controller circuit affecting the rear parking sensor circuit. To eliminate this concern, the harness to the rear parking sensor has been twisted to improve its tolerance to electrical noise.
Owners of these vehicles have filed 52 complaints in the driver assistance category.
