NHTSA Complaint #11693213 — 2024 TESLA MODEL Y

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.
