When my car was delivered, it had a bad #1 (left front) parking sensor. I had intermittent parking distance indications. Most often they didn’t appear in forward or reverse. Additionally, NOA, auto lane change, summon, and auto park did not work. I called support and they were able to do a remote diagnostic, review the car’s logs and identify that failed sensor. Was only at the dealership for about 30 minutes to have it replaced. Like magic, everything started working and has been rock solid ever since.
