2024 Tesla Model Y: lane keeping assist jerks the wheel

Filed Oct 30, 2026 · Driver assistance · CA

Following a software update (2026.38.3.2), without any prior warning messages or symptoms, the vehicle's onboard computer failed on 10/26/26, which resulted in the loss of critical driver-assistance and safety systems. The affected systems included the backup and side-view cameras, blind-spot monitoring, emergency braking, collision warning, lane departure warning/assistance, rear cross-traffic alert, GPS, and adaptive headlights. The loss of the cameras and blind-spot monitoring reduced my ability to identify surrounding vehicles and pedestrians, while the loss of automatic emergency braking, collision warnings, and lane-assistance features eliminated important safety functions designed to help prevent accidents. The problem was confirmed by a Tesla Service Center. According to Tesla's diagnostic findings: "In this instance, your vehicle's computer consists of both a primary and a secondary component. Our diagnostic findings indicate that both parts failed, not due to an internal short, but because of a complete loss of communication between the primary and secondary units." Tesla inspected the vehicle and determined that the computer required complete replacement. The vehicle is currently at the Tesla Service Center awaiting repair and will be unavailable for inspection. A previous recall (25V‑002) addressed a similar computer failure and relied on a software update as a remedy, however the recurrence of a related failure raises concerns about whether that remedy was sufficient. I am concerned that the automatic software update on 10/26/26 may have contributed to the failure of the car computer. The fact that the failure occurred after the update, without any prior warning, and resulted in the loss of multiple critical safety systems presents a serious safety concern. A software update should not leave a vehicle without essential safety equipment or render multiple driver-assistance systems inoperable.

SEVERE DEFECT: Unprompted autonomous steering overrides manual driving. When Autopilot is OFF, Emergency Lane Departure Avoidance (ELDA) violently yanks the steering wheel, steering TOWARD hazards like oncoming traffic on the left or a mountain/rock wall past the curb on the right. This creates a severe collision risk, overriding safe manual input.DOCUMENTED PROOF: Provided Tesla Service (Palo Alto) over 12 timestamps and several dashcam footage. Technicians physically verified NO internal/external camera obstructions across TWO separate visits. Moving a transponder failed to resolve it.TESLA REFUSAL: Service Center has canceled TWO other service requests without fixing the defect, claiming it the 'system is working as intended.' Crucially, the Manager Jay explicitly admitted this dangerous steering override is a 'known issue for vehicles without FSD' operating on an older, separate software stack prone to these errors. To resolve this critical safety hazard, he explicitly suggested I purchase Tesla's premium Full Self-Driving (FSD) upgrade, claiming the FSD stack fixes it. Tesla is fully aware their base active safety software stack is defective and steers into hazards, yet demands a paid consumer upgrade to resolve it rather than issuing a safety patch or recall.

I and others have noticed that once UNsubscribed from FSD, lane departure alerts and automatic corrections occur much more often than when subscribed to FSD, even if car is being driven by user. The alerts and corrections happen on almost every drive despite being within normal lane spacing. It feels like this is intentional to push users to subscribe back to FSD. Driving other makes of vehicles does not result in nearly this amount of warnings and corrections. Various online forum post corroborate this behavior. Even if there is an explained reason for it, Tesla does not notify the user of such changes that will happen once unsubscribing from FSD.

The contact owns a 2024 Tesla Model Y. The contact stated that while driving approximately 25 - 35 MPH, while driving near cones on the road, the contact manually turned the vehicle towards the right, and the steering wheel failed to perform as needed. The contact attempted to manually correct the steering wheel but was unable return the steering wheel to center because the steering wheel was independently turning to the left or the right. The contact believed that the vehicle was operating in self-driving mode; however, the vehicle was not equipped with the feature. The contact depressed the brake pedal to decelerate, almost stopping the vehicle, to regain control of the vehicle. The contact was able to drive to the destination. The contact stated that the failure had occurred while driving approximately 60 - 70 MPH, and the vehicle veered to the left and the right while the lane assist was activated. The contact depressed the brake pedal and decelerated almost to a stop to regain control of the vehicle. The manufacturer was informed of the failure, but the contact had not received a follow-up call. The failure mileage was unknown.

After Tesla Berkeley performed an alignment on my 2024 Model Y on July 22, 2025, the car suffered a complete systems failure while driving on the freeway. Within minutes of leaving the service center, multiple safety systems shut down at once — steering assist, emergency braking, lane keeping, stability control, etc... all turned off, and the car went into manual mode. The vehicle became extremely difficult to control at highway speeds, forcing me to steer and brake manually without assist. Because the Service Center was closed that evening, I couldn’t contact anyone, so I drove back first thing the next morning (July 23) to report the issue. I was initially told the next available appointment was two weeks later, but I had to beg to be seen the same day because the car was unsafe to drive. Tesla redid the alignment and told me the car was fine. After reviewing the alignment reports, both the July 22 and July 23 data are mechanically impossible. The reports show rear camber changes from −1.8° / −2.3° to −1.5° / −1.6°, then to −2.0° / −1.8°, even though rear camber on a stock Model Y is not adjustable. This means the alignment equipment or calibration was inaccurate, and therefore the toe settings were also unreliable. The car was almost certainly released with incorrect rear toe, which explains the immediate handling instability and safety system shutdowns. A later independent alignment on October 13, 2025 (America’s Tire, Roseville) confirmed the correct geometry (−1.9° / −2.0°) and proved Tesla’s readings were wrong. Since the faulty alignments, my car developed severe inner-edge tire wear, and I had to replace all four tires prematurely. This incident involved a total system and steering-assist failure immediately after service, making it a clear safety hazard. Documentation (alignment reports and tire invoices) are available upon reques

the steering wheel used to be centered in the middle. when you turn right, its resistance would turn it left back to the center point. or when you turn left, its resistance would turn it back right towards the center point. so after each turn such as u-turn, one would grab the steering wheel lightly so it can slide back to the center position. i will call it the "no resistance" point for that centered steering wheel position. now the problem is, that no resistance point has moved a few degrees right and it brings the wheel with it. i now have to turn the steering wheel left (with the resistance that it wants to go back to right) to make the steering wheel centered and go forward straight. car goes forward straight when the steering wheel is centered so it's not an alignment problem. but in order for the steering wheel to be centered, i have to turn it slightly left because the no resistance point has shifted a few degrees right. now this is dangerous because the car can now take you off the lane easily. car is equipped with lane keeping assistance and i find the system helpful but the system is not activated some times under some circumstances. I visited a dealer and they claimed the wheel is centered that there is no need for any repairs.
