“The rear wiper stopped working during a drive in heavy rain conditions, similarly like it happen to the same vehicle for the front wipers 6 months after I got the vehicle. I tried to schedule an appointment with the dealer but with the pandemic it was not possible. When I went for the actual appointment on march 2021, they told me the vehicle was out of warranty even though it is barely 3 years old, and just for a diagnostic they will charge $160 plus tax.

I will call the dealer tomorrow to have a fourth battery installed.... …”

“This is related to the existing recall with the backup camera. I have intermittently experience, fuzzing of the review camera. I have also experienced total loss of the review camera. In addition, I have had occasionally experienced the panel system not switching over to the rear view camera. The issues appear to be associated with opening and closing the rear hatch and if occurred could sometimes be resolved by turning the car off and back on. …”
