My infotainment screen goes black 10-12 times a year, and therefore I lose access to my backup cameras. I have to turn the car off, and then back on, in order for the screen to function again. This has been happening for the full 8 years I have owned the car. I also have video of this happening, but the file is too large to attach so including photo only.
On several occasions, the system would activate the panic braking while driving at low speeds in a few different situations. One situation is while pulling into a 2 car garage with objects along the garage walls, i.e. shelves in front of vehicle, lawn equipment on the side, grill on opposite side. While entering the garage the system would engage well before the front of vehicle is close to the shelving. Another occasion happened in a parking lot while driving at low speeds with no other vehicles or objects near the vehicle.
Complaints are unverified consumer reports submitted to NHTSA. A high complaint count may reflect vehicle popularity, not defect severity. Data sourced from NHTSA public records.
