1700 miles ago, the dealer serviced it, rotated tires, reset and all tires were at ~37. Now one is 32, others 34.
Same here. I’ve been experiencing many issues. Sometimes no sound with the music, collision light is no longer working, my seatbelts won’t lock in when brakes are hit. I noticed that when I had to stop suddenly. I turned vehicle off but it registered as if I was trying to start. My backup camera doesn’t show lines at times, front camera displays an error to clean windshield because of blockage but nothing was blocking it. I’ve been recording and taking pictures.
