2022 TESLA MODEL Y Complaints

My 2022 Model Y, 213k miles, battery health 77%, no issues until Beginning of November 2025. After Tesla’s update, BMS_a079 popped up, capped charge at 22%. No dead cells, no imbalance—pure software bug remotely triggered by Tesla. Service refused written diagnosis, only said ‘nine thousand dollars for new battery. Risk of stranding.

Vehicle: 2022 Tesla Model Y VIN: [XXX] Mileage: 85,000 Complaint Description (Copy & Paste): I am filing this complaint due to serious and ongoing safety-related defects with my 2022 Tesla Model Y that remain unresolved despite multiple service visits. The vehicle experiences shuddering and vibration during regenerative braking, especially when driving downhill. In addition, the braking behavior is unpredictable, which compromises vehicle control and creates a risk of loss of control while driving. These issues occur during normal driving conditions and present a significant safety hazard to myself, my passengers, and other road users. I have taken the vehicle to Tesla for service three separate times for this issue. Despite these visits, the Tesla service department has stated they are unable to fix the problem, and the safety concern remains unresolved. I’m being having this issues since I bought the car new.

On [XXX], while using Full Self-Driving (FSD) to drive to a hospital in Oak Park, Illinois, the vehicle experienced sudden unintended acceleration during the disengagement of FSD. As the vehicle approached the hospital area, I initiated disengagement of FSD to manually enter the parking area. During—or immediately after—the disengagement, the vehicle suddenly accelerated at full power without warning, causing an immediate loss of control and a collision with a nearby fixed structure. No system warnings or alerts were issued prior to the event, and the acceleration was so abrupt that manual intervention was not possible. This occurred in a low-speed, street-level environment where no acceleration was intended or expected and does not correspond to any normal driver input. Based on review of preliminary incident data provided by Tesla, there appear to be irregularities during the FSD-to-manual control transition, including missing or invalid input values, gaps in accelerator/brake/steering signals, and speed readings inconsistent with the crash severity. These indicators suggest potential instability in the real-time control system during disengagement. This report is submitted due to concern that sudden unintended acceleration during FSD disengagement may represent a safety defect with potential risk to drivers and the public.

While slowly backing out of a parking space at a Whole Foods in San Jose, CA, the driver's-side front wheel suddenly collapsed without warning. The front tire completely locked up, preventing further movement. Upon inspection, I found two bolts lying on the ground and the lower control arm detached and hanging loosely. The sudden jolt from the tire impacting the vehicle's body also caused minor damage to the plastic underbody cover. I had the car towed to the Tesla Service Center at 2801 Northwestern Parkway, Santa Clara, CA 95051, and it is now in their possession. Fortunately, this occurred at very low speed in a parking lot—if it had happened on the freeway, the outcome could have been catastrophic. I've since discovered similar incidents reported by other Tesla owners in this forum thread: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The car stopped in a busy freeway saying electric issue and doesn’t give sufficient time to drive to shoulder. This is the 2nd time this happened within 2 weeks. First time, tesla said high voltage controller had an internal issue with voltage sensing. the hv controller was replaced along with pyrotechnic fuse. Tesla assured this shouldn’t repeat and it repeated again. This has kept us in a catastrophic situation. I request immediate attention to this error and matter.

I have repeatedly had electrical failure in the vehicle in the form of a "Reduced Power Alert" which renders the vehicle with significant limitation to drivability. This places the vehicle in "limp mode" and this frequently occurs on the highway. Once this Alert appears the vehicle has limited propulsion, limitations to steering and braking as well as other electrical systems. It has been to the dealership for repair on 4 occasions without remedy. It is leaving us on the highway in a dangerous situation repeatedly. It's not a one time event. There were 20 Alerts showing on the screen when I limped it into the dealership once again on [XXX] having nearly wrecked on [XXX] just before the [XXX] exit. The reason this is so dangerous is the failures occur at higher speeds such as highway driving. Leaving one with an immediate loss of forward motion as if you've hit the brakes but vehicles behind you have no warning. This is going to end up with someone getting rear ended or worse. Social media indicates it is a prevalent and not well understood recurring problem. Tesla has been quietly repurchasing vehicles from angry owners. Dreadful.

To the National Highway Traffic Safety Administration, I am filing a formal complaint regarding a dangerous safety defect in the 2021 Tesla Model Y. On December 2, 2025 at approximately 4:25 PM, my vehicle suffered a sudden, complete electrical shutdown while I was driving, with no warning and no opportunity to reach safety. Critical details: The vehicle displayed an electrical system message, then instantly powered down. I lost all ability to steer or move the vehicle, which remained immobilized in active traffic. Hazard lights did not function, leaving the vehicle unmarked and invisible to oncoming vehicles. Electronic systems failed, requiring manual release of the driver door. The incident occurred at dusk and blocked the roadway, placing myself and others at significant risk. This failure presented an immediate threat to life and safety. I have since discovered that other Tesla owners have reported similar abrupt electrical or drive-unit shutdowns, suggesting this may represent a broader systemic defect. I am formally requesting that NHTSA investigate whether this issue meets the threshold for a safety recall and whether Tesla’s systems contain a defect capable of causing sudden, uncommanded shutdown while driving. Thank you for your prompt attention to this matter. I am prepared to provide all supporting documentation, including incident details, screenshots, timestamps, and service correspondence.

My high voltage drive inverter experienced a failure resulting in loss of all power as well as regenerative braking. Mechanical braking and steering remained available. There were no warnings or indications before the failure. After the failure there were warnings that the propulsion system had failed and to pull over immediately.

Tesla Collison Center Denver - returned vehicle with bent wheel after an accident They refuse to repair despite safety risk They are now Blocking my access to service of fixing my car for unrelated issues as well. This bent wheel may result in an unsafe vehicle on the road

On October 13th 2025, while driving, I began to hear a clunking and rattling sound from the front left wheel area when braking. Concerned for my safety, I brought the vehicle to a local independent brake specialist for inspection. Their technician found that one of the two bolts securing the brake caliper was completely missing, and the remaining bolt was approximately halfway backed out. The shop explained that this condition presented an immediate risk of caliper detachment and total brake failure, potentially leading to serious injury or death. After both bolts were replaced and properly torqued, the brake noise that Tesla had previously attributed to “pad burnishing” disappeared entirely. This indicates that the squeaking and vibration symptoms Tesla dismissed were, in fact, caused by an improperly secured caliper—a direct safety issue, not a normal wear condition. I notified Tesla legal of this problem (via certified mail) on October 13 2025 and requested a response within 14 days. I have received no such response, nor have I been contacted for further investigation into this dangerous situation with my vehicle.
