2016 Tesla Model S: lane keeping assist jerks the wheel

Filed Mar 3, 2026 · Driver assistance · SD

multitude of electrical problems: Fuel/Propulsion System, Lighting, and body controls along with all ADAS: Adaptive Cruise Control, Automatic Emergency Braking, Blind Spot Warning, Forward Collision Warning, Lane Departure Warning, Lane Keeping Assistance systems are impacted by random intermittent glitching as computer screen bubbling progressed with goo leaking out of the bottom of the main computer. Most recent symptom was disabling of ALL ADAS systems along with automatic high beam headlight switching. Long ago as screen began to bubble and express fluid the low windshield washer alert came on and remains even when the tank is full. Then the charge port responsiveness degraded and stopped automatically functioning requiring user to bypass by clicking the "open charge port", then waiting 3 seconds, then tapping "unlock charge port". User must perform this as remote manual operation from a NACS charging handle button push will FAIL. Long ago the computer controlled 'home link' module would have excessive time delays on the order of hours or days from when the user would program and or operate the function. I even had a "phanthom" car appear by the computer calculations with E-Braking before the ADAS system failed fully, a 1.0 Tesla system should not have that... Windows have randomly rolled down and the driver side rear door will unlock and open on its own as the door handles present themselves. The safety risk class is unknown unknown; if the root problem is the screen filling leaking on electronics any number of unknown, unplanned, unstudied risk failure modes exist that can not be predicted. Schematically the HOMELINK is on connector X429 sharing CANBUS connections impacting safety: Driver "Instrument Cluster", DAS systems connected to "Power Steering ECU", "iBooster ECU", "ABS / Stability ECU", "Passive Restraints Controller"... see CAN Network - Chassis drawing page 11 , "Energy System - Charger Logic Connections" "Instrument Cluster / LIN" pg35

1.) Passenger Side Door is a potential hazard. Door latch and door mechanism does not open from the outside. 2.) Lane keep assist on Autopilot veers off to the right when it is first engaged and does not want to stay centered until it's been on for awhile.

The main computer in the car goes blank. This affects all parts of the car. It has happened while stationary and in motion. When it shuts off you lose control of all systems including: navigation, emergency braking, lane assistance, use of cameras, all access to safety features. I have read there is a recall but when I contacted the manufacturer they refused to fix the issue.

Multiple center screen failures experienced since october 2020. Most notable highway driving incidents listed below. 18nov2020 while driving center screen became unresponsive. The driver seat heater was stuck on level 3. The turn signal sound continued after the turn signal was turned off. Climate controls couldn't be turned off. No response to radio selections. 10 mins later the radio came on at a very loud volume, but unable to reduce or mute volume. Volume muted after 10 mins. The screen rebooted, no cell signal. 19nov2020 driving, the touch screen went black. Attempted to reboot using the scroll buttons several times. It did not respond. I rebooted the driver's screen, then the center screen began to reboot. The tesla symbol appeared and disappeared 4 times over 5 minutes before the center screen came on. Car unable to connect to cell services for several days. 26nov2020 driving, all systems appear to be normal accept there's no volume, and no turn signals. Center screen went black. Cannot stop ventilation. 4 hours after parking car the ventilation is still on, but the driver screen shows that the ventilation is off. Center screen does not respond to reboot attempts. Battery power getting low. Finally recovered center screen after 36 hours. 02dec2020 center screen went black and did not come back on. Request for appointment with tesla made. Earliest appointment is 21dec2020. Have not been able to reboot center screen after many attempts. 12 days later and screen is still not recoverable. When the center screen goes black the following features are out of commission: turn signals back up camera climate control & seat heaters(if on, I cannot turn it off) hazard lights tire pressure sensors autopilot features adaptive cruise control lane departure warning blind spot warning infotainment charging controls

Autopilot suddenly swerved vehicle out of the lane to the left toward a bridge abutment. I had to yank control away from autopilot to recenter vehicle in the lane. I provided a detailed written description of the incident along with the time of the recorded "bug report" to tesla's service center. Tesla wrote the problem in the repair order as "customer concern - auto pilot is inconsistent" rather than the more accurate and more serious description I provided in writing to them. Tesla's final paperwork said system is "operating as designed." a lane keeping system should be designed to keep a vehicle within a lane, a lane keeping system shouldn't suddenly steer the vehicle out of the lane. The way autopilot suddenly swerves out of the lane should not be considered normal. This problem has occured multiple times.
