2020 TESLA MODEL 3 Complaints

I own a 2020 Tesla Model 3. Over approximately the past 2–3 weeks, the vehicle has developed a noticeable rattle/creaking noise coming from the left-front suspension area. The noise was not previously present and appears to be getting my attention as a potential suspension-related safety issue. I am concerned because my vehicle falls within the model-year range of Tesla Model 3 vehicles associated with reported front suspension/lateral-link issues. I understand NHTSA is investigating reports involving front suspension component failures that could potentially affect vehicle control. I contacted Tesla through the Tesla app and requested that the vehicle be inspected because of the suspension noise and my safety concern. Tesla provided an estimate requiring approximately $240 for diagnosis/inspection before determining the cause. At this time, I have not experienced a suspension separation, crash, injury, or loss of vehicle control. However, because the vehicle is producing a new and persistent noise from the left-front suspension area, I am concerned that this could be an early indication of a suspension component problem. I am submitting this complaint so NHTSA has a record of the symptoms on my vehicle and can determine whether they may be related to other reported front suspension failures. I am also requesting that this complaint be considered in connection with any ongoing investigation involving front suspension/lateral-link failures in 2020 Tesla Model 3 vehicles. I will retain Tesla service records and any inspection findings and can provide additional information if requested.

The tire skid marks were 100 feet long. The air bags failed to deploy. The contact stated there was an electrical failure which caused the brakes to become inoperable. Additionally, the alerts were late. The contact stated that the battery might need to be replaced. The driver and his daughter, who was seated inside the vehicle, sustained back pain, whiplash, and knee injuries. The driver was transported by ambulance. Medical attention was provided. The contact stated that surgery might be needed in the future. The daughter was taken to the hospital, and medical attention was provided. A Police report was filed. The vehicle was towed to an auto body shop. The EDR was requested on the manufacturer website. The failure mileage was approximately 119,730.

The contact owns a 2020 Tesla Model 3. The contact stated that while driving at an undisclosed speed, the safety features independently deactivated. The contact purchased and replaced the battery. The vehicle was taken to the dealer, where it was diagnosed with ECU failure. The contact was informed that the ECU needed to be replaced. The vehicle was not repaired. The contact stated that an unknown software update was completed in June 2026. In addition, the contact stated that the unknown software update caused the ECU to fail. The manufacturer was made aware of the failure, and a case was filed. The contact was informed that the failure was a known failure with similar vehicles. The failure mileage was approximately 80,000.

The front passenger door intermittently becomes “unclosed.” When this occurs, the vehicle displays “door open” and the passenger door window rolls down and up repeatedly. The window cycling continues until the door is slammed firmly shut. Once the door is securely shut, the window cycling stops and the door-open warning clears. When it occurs: The issue began in the second week of August while a passenger was in the front seat. It continued while the passenger remained seated. The issue occurs intermittently while the vehicle is moving, including when the vehicle goes around a curve.

I was told my car is unsafe to drive after taking it to the mechanic for a routine tire balance and rotation. I currently need both rear control arms replaced. I had them replaced in the past. In addition, I have had the front control arms replaced more than once, the lower lateral links replaced, numerous hubs repaired, forelinks and knuckles all replaced not too long ago, so this news comes as a shock. The first control arm failure occurred when the car was only a year and a half old with very little milage. I have all of the service records in my tesla app vehicle repair history. They are in a pdf format and I would be happy to send them in, if helpful.

I was operating my Tesla with Full Self-Driving (FSD) engaged when the incident occurred. I was turning right onto [XXX] from [XXX] and was positioned in the left right-turn lane approaching a railroad crossing. The railroad crossing gates were already fully lowered, indicating an approaching train. Despite the lowered crossing gates, the vehicle accelerated forward into the crossing rather than stopping. The vehicle drove through the lowered crossing gate, which struck and shattered the windshield. Seconds later, the train passed through the intersection. I did not command the vehicle to proceed through the lowered gates. The incident resulted in significant damage to the windshield and raised serious safety concerns because the vehicle entered an active railroad crossing immediately before the train arrived. The vehicle was towed to a Tesla Service Center due to the damage. Fortunately, no collision with the train occurred and there were no injuries, but the incident had the potential to result in catastrophic injury or death.

All Teslas vehicles running HW3 / AI3 Autopilot self driving computers have been known for years to have a defective design problem with the cooling system without its own dedicated cooling and which puts the self driving computer last in the cooling looping at the top of the cooling stack. When the computer fails and they will Tesla requires the owner to replace the computer. This does not result in a redesigned improvement to the computer or cooling system that reduces the thermal stress being applied to the new computer. Tesla is now pushing a new version of the self driving FSD software with the “v14 Lite” release over the last two weeks. This software release uses large complex software models which Tesla design to use every part of the HW4 / AI3 compute power which stressed the computer by pushing it to it compute limiting. All this compute is causing the computer to overheat and fail. Tesla then require owners who are all out of warranty now to pay thousands to replace the computer. This replacemen uses the same flawed cooling system and the same computer incapable of dealing passive compute requests on it by the latest v14 Lite software to eventually cause the computer to just require the replacement computer to eventually need yet another replacement of the same flawed design at owners cost. There is also supposed to systems which monitor the thermal stress on the computer and shut it off abruptly until it cools down which is not ideal at freeway speeds which is not happening. Recall to address and resolve the issue with improved cooling, more powerful computer that doesn’t reach maximum capacity and it’s each use, and less taxing software needs to be issue. This is a major safety design problem which Tesla has not addressed. There only solution is to just replace design constrained components with the exact same parts at owners cost. These multiple design issues can and often result is sudden shutdown of the computer, or worse case sudden complete failure.

I own a Tesla Model 3 and have been experiencing concerning front suspension and steering issues that appear to be worsening over time. While driving and especially during low speed turns, parking and maneuvering, the front suspension produces loud screeching, squeaking, and rubbing noises. The steering has also become noticeably stiffer that normal at times, and the noises can be felt through the steering wheel. The sounds are coming from the front suspension area and occur repeatedly during normal driving. The issues raises significant safety concerns because I am worried there may be a defect affecting the front suspension of steering components. Unexpected steering resistance combined with loud suspension noises creates concern that a suspension component could fail while the vehicle is in motion, potentially resulting in loss of steering control or a crash. There were no warning lights or messages displayed before or during these symptoms. The vehicle has not been involved in any collision that would explain these symptoms. The problem has continued during normal operation and appears to be getting progressively worse. The vehicle is available for inspection upon request. I am submitting this complaint because I understand NHTSA is investigating front suspension issues involving 2018-2020 Tesla Model 3 vehicles, and my vehicle is experiencing similar symptoms. I believe this issue should be investigated to determine whether it is related to the front suspension components under investigation.

The front upper control arms. Causing poor steering and unbearable loud creaks when turning wheel. Mobile tesla tech confirmed upper control arm

Component that failed was the lower lateral link. There was no loss of control but there was a sound going over any uneven surface. Upon bringing the vehicle to the Tesla dealership they recommended a replacement of the upper and lower control arm on both the driver and passenger side. This greatly increased the cost of the repair to a total of $2356.84
