ENGINE, FUEL/PROPULSION SYSTEM, ELECTRICAL SYSTEM
I was on the freeway in the fast lane approaching a tunnel and vehicle came with warning vehicle shutting down. Code DL_a063. Vehicle stopped in fast lane would not move to shoulder. No prior warning there was any issue. State police came and had vehicle towed. Lucky the car behind me was able to stop in time.
SERVICE BRAKES, ELECTRICAL SYSTEM, STEERING
While operating the vehicle at low speed (~35 MPH reducing to a stop) on August 1, 2026, at approximately 10:38 AM under normal road and weather conditions, the vehicle experienced a catastrophic and simultaneous loss of primary braking capability and steering responsiveness. > Detailed Description of Failure: > * Brake Failure: Upon pressing the brake pedal, the vehicle failed to decelerate or stop adequately despite continuous application, nearly causing a collision. > * Steering Loss / Disconnection: Concurrently, while the steering wheel could physically be turned, it offered no directional control—turning the wheel had no effect on the vehicle's path, feeling as if the steering linkage or assist was entirely disconnected or disengaged. > Vehicle Warnings / Diagnostic Codes: > The vehicle's onboard display immediately registered critical active safety and chassis failures, specifically displaying: > * "ABS (anti-lock braking system) disabled - Drive with caution" > * "Automatic Emergency Braking is unavailable - Feature may be restored on next drive" > Dashcam video and system screen captures documenting the exact speed, timestamp, and error messages have been saved and are available upon request. No crash occurred, but the sudden, simultaneous failure of core braking and electronic steering systems presents an extreme safety hazard. >
WHEELS, SUSPENSION
A front wheel of this vehicle and/or its suspension is undergoing extremely dangerous vibrations at highway speeds (65-70+ mph). It is enough to shake the entire vehicle multiple times per second. The local service center, without looking at the vehicle, stated it "would be fine to drive on until your appointment" and scheduled an appointment nearly a month out into the future after I brought up concerns that the vehicle is unsafe to drive. They also would not recommend any third party service centers to look at the vehicle in order to address the concern more urgently, nor offered any alternatives such as rentals or loaner vehicles to use in the meantime. I understand that car issues will come up; my complaint is due to how it is being handled (long wait time for an appointment, dismissal over safety concerns, no alternatives to drive safely in the near month-long wait for the appointment).
FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, LANE DEPARTURE: WARNING, LANE DEPARTURE: BLIND SPOT DETECTION
I am filing a formal safety complaint regarding a severe braking and stability control failure that resulted in unpredictable, highly dangerous vehicle behavior. While driving, the vehicle displayed a cascade of critical system failures, throwing error codes APP_w009 (AEB disabled), DI_a222 (Stability control disabled), DI_a223 (Traction control disabled), ESP_a080, and ESP_a067 (ESP/ABS sensor faults). This concurrent breakdown caused a total loss of critical safety features: Anti-lock Braking (ABS), Automatic Emergency Braking, Traction Control, "Vehicle Hold," and "Hill Start Assist." Because the vehicle completely lost its ability to hold its position, it unexpectedly free-rolled backward on an incline when I anticipated it to remain stationary or move forward. This uncommanded movement created an immediate collision hazard. Of serious concern is that despite a total breakdown of vital braking and stability assists, the vehicle remained fully drivable and only advised me to "drive with caution." Allowing a car to remain operational under these severe fault conditions is an unacceptable risk. A driver expecting normal EV behavior (like vehicle hold and regenerative braking) is placed in immediate danger when the vehicle suddenly free-rolls without warning. The software should classify a multi-system ABS/ESP failure as a critical emergency requiring an immediate safe shutdown, rather than suggesting it is safe to continue driving.
STEERING, ELECTRICAL SYSTEM
While out on vacation in [XXX] on XXX at around 11 am I had just finished charging the Tesla at a supercharging station. I was headed to go eat breakfast at the intersection of [XXX] and XXX on the right lane. I stopped briefly prior to making a right onto [XXX]. Upon making the right turn the vehicle kept turning all the way right and making a sharp right turn instead of a soft right. When I noticed the sharp right turn I tried to turn the steering wheel towards the left but the steering wheel was locked and it wouldn't respond. The car drove me into a concrete barricade and caused a collision. My children were in the car and thankfully no one in my vehicle was seriously injured nor were there any pedestrians on the sidewalk near the barricade. I contacted Tesla for the repair and investigation into why the steering wheel locked. Tesla has not provided a loaner vehicle in the meantime despite my frequent requests. This incident is a serious and critical safety issue that may have caused deaths had I been traveling at a higher rate of speed or been on the highway heading back to [XXX]. The strange thing is that this vehicle is still under warranty with Tesla and had been working just fine without any issues since I got the vehicle in XXX. No warning messages, or symptoms to indicate any malfunction. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
