Owner report 11692015 · 2025-10-08 (October 8, 2025)

While this may sound trivial - and if this system just did the radio - I would agree. However it controls most all the sub-systems of the car from Charging, to Display, to GPS, Environmental, etc. While at home it is just annoying and frustrating - we traveled to VA from FL this past week. Traffic was horrendous due to a closure of I95 in SC - ALL traffic was forced onto 2 lane country roads. Attempting to use the Control…

I was driving on a rainy day, and noticed my windshield wipers were not working. I tried adjusting wiper speed and even the spray function, which sprayed but did not wipe. At this point I had driven over a mile and had to pull over because visibility through the windshield had gotten so bad. I restarted the car and the wipers functioned normally again. There were no warning lights of any kind or software notifications, and the wipers had worked previously that day.
