Three problems related to wiper have been reported for the 2019 Tesla Model S. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2019 Tesla Model S based on all problems reported for the 2019 Model S.
After a recent Tesla firmware update, the backup camera (fmvss 111 rear visibility function) stopped working. When shifting into reverse, the display shows a black/blank screen instead of the required rearview image. However, the rear camera preview feed still functions, indicating the camera hardware is intact and the failure is likely in the mcu/deserializer routing or software handling of the reverse camera mode. Tesla service refused to investigate the firmware or signal-routing path and instead recommended a full mcu replacement at my expense without providing diagnostic logs or evidence that the update was not the cause. They closed the case and declined further review while the federally required safety feature remains inoperative. This appears to be a software- or firmware-triggered failure of a federally mandated safety system following a Tesla-pushed update, and I request NHTSA review.
The intermittent wipers do not work at all. I created a service ticket with Tesla and they informed me that this is a known bug affecting Model S & x vehicles and that there is currently no known date for a fix to be released.
Driving down the road on a 25 degree day. I turned on the front defroster and the entire windshield cracked across the entire windshield. I've heard of other Tesla owners having the same problem. Cheap untested glass. All Teslas need new glass. Two weeks later I was driving on a 20 degree day, turned on the rear defrost and the entire rear glass cracked. Zero chance that either of these problems were cause by external issues. Both occured on sunny days with no other traffic anywhere near me. Purely poor material and poor engineering and/or inadequate testing.
