Assist problems of the 2017 Volkswagen Passat

While driving straight in dry weather (I. E. No rain), the lane light will change from – green – to – yellow – color in the dash and the steering wheel will jerk, usually left, sometimes right, very abruptly, as if the car is trying to find the lane with lane assist on. Note, this is on well marked city streets and on regular interstate roads with clearly marked dashed lane lines. This has been happening for at least two months (today's date Dec. 12, 2021) and only now reporting this complaint. It did almost cause me to run into the car beside me several times or turn into the center median (trees) on city streets.

On starting the vehicle for the first time of the day, console display indicated lane assist was disabled. It was necessary to access the menu system and re-enable lane assist. Lane assist was enabled when the vehicle was parked the previous day. Lane assist has many times somehow become disabled and cleared on the menu system while the car was parked overnight. The problem and others have been reported to Volkswagen several times. After lengthy service visits since 2019, Volkswagen have been unable to correct or explain the faults. Volkswagen insist no error codes have been recorded in the system. All thing considered, the ongoing absence of error codes may be yet another fault.

While driving at approximately 10 mph, the message "lane assist currently not available" was displayed and lane assist deselected in the system menu. Later, while parked, I re-enabled lane assist using the menu system. This problem, along with others, has been ongoing since 2019. Since 2019, Volkswagen have been unable or unwilling to correct any of the problems experienced with the vehicle.

While stopped at an intersection with no moving traffic, the park assist enabled itself warning extreme proximity to something on the left side of the vehicle. As with other faults, the park assist faults have occurred numerous times since 2019. The lane assist system unexpectedly disabled itself while driving less than five mph on a slightly inclined driveway.

The emergency breaking incident first occurred on 8 December 2019 as I was entering the parking lot for my apartment complex. There were no obstacles. The second occurrence was reported to the NHTSA on 5 may 2021. The tracking number for the issue is 11415338. The vehicle has exhibited multiple faults with its electronics, including emergency breaking enabling for no apparent reason, lane assist randomly disabling itself (including driving and overnight while parked), parking sensors alerting extreme proximity when nothing it near the vehicle, infotainment system (failed to move from vw display, locked up, failed to display rear camera with vehicle in reverse and other failures), the rear camera has failed to display and displayed a image "rolling" vertically, wing mirrors have failed to extend or extend after considerable delay, and other issues. All of these issues have been reported to Volkswagen and service has reported no problems. Additional information, photos, and video are available.
