2023 Tesla Model 3: lane keeping assist jerks the wheel

Filed Oct 22, 2025 · Acceleration, Driver assistance · CA

On August 7th, 2025 at around 8 AM in the morning, my vehicles mobile phone car key was in-operable and I was unable to get in the car which led me to trouble shoot how to fix this issue with the car. Upon researching I was directed by Tesla to directly complete a soft reset of the vehicle holding down both buttons on the vehicle once I was inside, and pushing on the brake pedal. Upon completion, my vehicle booted up and I realized that all camera systems were down, my navigation systems were down, my safety features were down, my auto pilot, lane keeping assist and auto brake were down, sensors were down and I was no longer able to pre heat my battery to charge my vehicle due to issues with the navigation. I then took the vehicle to Tesla Service Center Irvine where a service advisor quoted me 2900 for a new ECU and Bolts and told me that I needed to replace my whole unit and that I was to cover the cost of the repair even though my vehicle is only 2 years of age and this failure is due to the quality control and software of the vehicle. I have been driving around a vehicle with absolutely no safety features whatsoever such as no cameras, sensors, auto braking, or full self driving due to this ECU failure and I fear for my safety and well being while driving this car.

My dad was driving to work in the morning in the Tesla in the left lane of the freeway. Then the car started swerving on its own. He tried to regain control with the steering wheel but he couldn’t control it. The car wouldn’t turn when using the steering wheel and he was not using autopilot or lane assistance. He said it felt like the steering wheel and the car were not talking to each other. And the brakes weren’t stopping the car at all and because he couldn’t control the car it turned left into the divider and hit the divider and the car turn again to the right and automatically stopped in the middle of the second lane. The airbags deployed for the driver side. Thankfully there weren’t any other cars on the road at the time so there aren’t any injuries. But this crash could’ve caused serious injuries to him or other people. There were no warning signs, alerts, or noises before this happened. He has filed a claim with the insurance company. And a crash report was filed by the police.

Vehicle started displaying warning messages as I pulled out of garage - "steering assist reduced" and "lane departure avoidance features unavailable." Afterwards, I noticed vibration and clicking sensation while turning steering wheel and driving at low speeds. I performed a software reset but messages were still there. Then I performed controls, safety, power off procedure. Messages disappeared, but steering still felt jerky. This happened when the vehicle had approximately 2,300 miles on it. A few days later, when exiting the garage, steering wheel was initially locked. It then "popped" when I applied gentle pressure to turn the wheel and the warning messages returned. Steering felt stuttery afterwards. I scheduled service appointment with Tesla. They replaced steering rack. I have had no problems since. Currently at 3,700 miles.

As part of transitioning from radar to a camera based system (this affects model years '22 onward), Tesla, has "temporarily" disabled key features such as lane departure, blind spot alerts and emergency braking. Though disabled, these features are still selectable (not greyed out) when the user chooses safety options. These features, which are available on most modern cars, have been disabled for many months with no committed date to restore functionality ... this poses a major safety risk. This should impact Tesla's the federal safety agency safety rating which will pressure the company to re-enable these basic safety features ASAP. Thank you.

I was driving and the power steering stopped functioning. The car had just over 1000 miles and both the lane departure avoidance and steering assistance cut out. Restarting the start would bring it back on temporarily but it would cut out again after a minute or two.

While driving, both while using Adaptive Cruise Control and while using "Autopilot" (automatic lane centering), the car has severely emergency braked with no input from me. The conditions were bright sunlight, with mirages on the roadway in front of the car. I believe the car cannot tell the difference between these mirages and actual obstacles. The emergency braking is severe enough to potentially cause an accident, with speed rapidly dropping from 70 mph to 45mph. This is a serious defect that needs addressed ASAP.

Tesla's traffic aware cruise control (adaptive cruise) frequently brakes hard for no reason (aka "phantom braking"). This behavior occurs multiple times per week during my daily commute on a two lane highway. It happens at different locations, different times of the day, and with or without other vehicles around. "Autopilot" is disabled so there is no auto steering or lane centering. Unnecessary hard braking will significantly increase the chances of a collision with other vehicles, especially with higher levels of traffic. This problem is a well known issue with "vision only" Teslas with no radar and has been documented by many other owners. This issue has been occuring since the vehicle was new and is a system design issue, not a specific part failure. There are no warnings or other messages. There is currently no way to disable adaptive cruise control and use basic fixed-speed cruise control.

I was driving on the HOV lane (going between 65-70 miles mph) with the adaptive cruise control and lane keep assist on when the car suddenly slammed on it’s brakes to stop. There was a slight hump in the highway, but no car or object in front of me in the lane. Thank goodness there were no cars behind me or they could have easily rear ended me. It was extremely scary and now I’m too scared to use these driver assist features moving forward.
