2021 TESLA MODEL Y Complaints

Incident Date: April 11, 2026 Approximate Time: 6:30 PM Component(s): Unknown (Suspected: Electronic Stability Control, Steering, ADAS) Description of Incident: On April 11, 2026, at approximately 6:30 PM, I was operating my Tesla Model Y on a highway with a self-driving mode engaged. I experienced what appeared to be a sudden, unintended acceleration combined with an erratic "zig-zag" steering pattern across multiple lanes. I am not certain of the technical cause, but the vehicle’s behavior felt like a loss of system control that was not initiated by me or the road conditions. I had to intervene immediately to prevent an accident. Post-Incident Actions and Manufacturer Contact: I have since contacted Tesla Service, and while they confirmed that data for that date exists, my formal "Privacy Data" requests for those specific logs have come back empty or missing the relevant timeframe. Summary of Concern: I am reporting this because I suspect a serious software or hardware malfunction occurred, though I do not have the technical diagnostic to confirm which system failed. The combination of the vehicle’s erratic movement and the subsequent difficulty in obtaining the data logs for this specific window of time leads me to believe there is a potential safety defect that requires investigation.

**What component or system failed or malfunctioned, and is it available for inspection upon request?** The vehicle experienced a critical failure immediately on the same day of purchase, rendering it not functioning or inoperable. It was deemed to be preexisting from the dealership I bought it from. The battery is malfunctioning affecting the driving capacity and range. --- **How was your safety or the safety of others put at risk?** The failure created a significant safety concern, as the vehicle was not operating reliably immediately after purchase. This placed me at risk of being stranded and potentially exposed to hazardous conditions, including loss of transportation in unsafe or uncontrolled environments. Or stopping while driving. --- **Has the problem been reproduced or confirmed by a dealer or independent service center?** The issue was immediately reported to the dealership, and they acknowledged the problem by agreeing to an exchange of the vehicle due to its defective condition. It was confirmed by a service center of the car's manufacturer. --- **Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others?** At this time, the vehicle has inspected by the manufacturer. --- **Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear?** Yes, although the manufacturer can't pinpoint when they started but said they had been on since ATLEAST March 10. My purchase was made April 1, undisclosed to me of this huge issue.

The paint on my Tesla Model Y is peeling and delaminating along both sides of the rear trunk/hatch seam, adjacent to the rear glass. The issue appears in the same location on both sides in a symmetrical pattern. There has been no accident, impact, or external damage to these areas. The peeling began gradually and has continued to worsen over time. The symmetry and location suggest this is not normal wear or environmental damage, but a potential defect in paint adhesion or manufacturing at the trunk seam. This condition exposes underlying material and may lead to further deterioration, including corrosion over time. I am reporting this as a potential manufacturing defect affecting durability of the vehicle exterior

Squeaking (lubrication failure) of the front suspension components, prematurely, are a common and widespread issue with Tesla vehicles. I have approximately 60k miles on my model Y and the front control arms are making noises. Tesla wants to replace a significant amount of suspension components at a high cost, instead of a recall (or creating serviceable lubrication points on these components). The NHTSA needs to hold Tesla accountable for faulty suspension design and lack of maintainability leading to premature failure.

The back drivers side seatbelt belt does not latch. The manufacturer refuses to fix without a fee.

Getting message on screen since october 2025. That time total milage on my car was less then 30,000 STEERING ASSIST REDUCED and LANE DEPARTURE AVOIDANCE FEATURE UNAVAILABLE. I did reset / restart the vehicle / soft / hard reset, software update. and This both message got disappear and then again after sometimes its keep coming back. So i did appointment to rocklin tesla center and they gave me cost estimate $5770. Thats way too much so i decline but they said those message might keep popping up because of LOW VOLTAGE DISTRIBUTION AND CONTROLLERS. So i accepted that service and paid $359.68. But i am still getting same both messages on my tesla screen. Sometimes it does comes and sometimes it does not. I did online research and people with same problem stating that because of TESLA's poor manufacturing steering wheel and some kind of faulty circuit board causing this issue. My car never been to any accident and its very low on milage. Please look for other tesla owner who has same problem and tesla has to fix this problem without charging this much amount. Thanks

I was entering the on-ramp to [XXX] , from [XXX] , to merge onto the freeway east bound towards [XXX] , when my Tesla suddenly lost all power, the brakes did not work and the power steering completely failed making it feel like it was locked up. I was traveling approximately 40-50 mph at the time nearing the gore point to merge onto the freeway. Fortunately I was in the inside lane and I rolled to a stop away from other vehicles. I could not steer at all. Had I been completely on the freeway, I could have been rear ended badly. I had my two young boys in the vehicle with me, both [XXX] and [XXX] . We were completely trapped in the vehicle with no power. My [XXX] old remembered to use the manual latch to get out. I opened my door manually and It broke my driver side glass window. Vehicles were passing us rapidly to enter the freeway. I called my husband who is a police officer and he came and picked us up. We called Tesla who said they could not get a read on our battery whatsoever. We called a tow company and had this vehicle towed to Tesla repair center in [XXX] , after reporting our traumatic event. They claim our warranty is expired, but our vehicle only has 37,638 miles and should be covered under the 8 year, 120,000 mile warranty that covers a major malfunction like this.

While on my way to run an errand, I opened up the back door to strap my 2 year old in, when i closed the door, the car would not open whatsoever, after trying for a few minutes with the phone key app for tesla and the physical key fob, nothing would work. I had to end up calling 911 and firefighters came out and had to physically open the door, which broke the window. The car was completely unresponsive and would not turn on. After researching what happened, it turns out the 12v battery had died. I was able to jumpstart the car with jumpers and that was able to open up the rest of the car's doors. However, during the time my son was stuck inside with the over 95 degree weather, the had no safety mechanism in place to open it physically like a traditional key fob would. It is very disheartening knowing my son could have potentially lost his life over something so simple that could be resolved with a physical keyhole on the outside like almost every traditional vehicle has. This is something that should not occur, ever. The fact that the car was able to open up once more before completely dying and perfectly at the wrong time after closing the door while my son was trapped in there in complete heat was very disappointing.

I own a 2021 Tesla Model Y with approximately 46,500 miles. The vehicle is currently displaying battery error code BMS_a079, and the battery will only charge to approximately 30%, which severely limits the driving range and makes the vehicle unreliable for normal use. I reported this issue to Tesla on March 6, but the earliest service appointment available to me is March 17 at the Tesla service center in Fayetteville, Georgia. Because Tesla service centers are not widely available, I must travel to another city to have the vehicle inspected. The limited battery charge creates a difficult situation because I must determine how to get the vehicle safely to the service center with very restricted range. I may have to arrange towing or attempt to drive a vehicle that cannot fully charge. This issue has also created a hardship for my household. I have a toddler and normal daily responsibilities, including errands and transportation needs, but the vehicle cannot reliably be used due to the charging limitation. Being without dependable transportation for an extended period of time places families like mine in a very difficult position. This problem appears to be related to the vehicle’s battery management system and is not the result of driver misuse. Consumers should not be placed in situations where a major battery fault leaves them with limited transportation options while waiting extended periods for service, especially when service centers are not easily accessible.

The vehicle's Autopilot/Full Self-Driving (HW3) computer has failed at approximately 70,000 miles. Tesla Service has diagnosed the vehicle as requiring replacement of the HW3 computer. As a result of this failure, multiple safety related systems are inoperative, including collision avoidance, lane assist, lane departure warning, automatic wipers, and other driver assistance features including adaptive cruise control. The vehicle is also unable to receive over-the-air software updates, including potential safety updates. In addition, the vehicle experiences system lag, including delay when shifting into Drive or Reverse. The center display is slow to respond, and certain media and software features are no longer functional due to inability to update. This condition increases safety risk because active safety systems designed to assist with collision prevention are disabled. The failure appears to be hardware-related and not due to normal wear. Tesla has confirmed the need for computer replacement but has declined coverage as the vehicle is outside warranty. The failed component should be available for inspection upon request.
