Just got the 2018.26.1 at SC and tried Summon for the first time. Every time I pressed Forward or Reverse, the car would start trying by making noise and turning on the lights. However, it stopped before making any move. I called the Service Center for this issue. The rep checked the log and found that #12 sensor failed. Is it one of those supersonic sensors on the front or rear bumper? Two issues identified previously are potentially related to the failed sensor: Auto Lane Change: It always reports that the Auto Lane Change isn't available. If the problem persists, please contact the Service Center. Parking: When I pulls into my garage, the concrete garage wall in front of the car is shown as a car instead of the distance lines. I recently installed front clear bra and full-body opti-coat on my car. But the PPF has the cutouts for all the front-bump sensors. Besides, I experienced the Auto Lane Change and Parking issues before the installation. Anyone has similar experience?
