I was in full self driving mode and was travelling North bound 110 freeway transitioning to 405 freeway Northbound. In the right lane. Transition curved left. looked at my speed for a split second and as i looked up we were a split second from hitting freeway barrier head-on. We crashed through the barrier and ended on the embankment of the freeway. My car front end was totally demolished, front airbags went off. I was ok, but my wife suffered a L1 vertebrae fracture and was taken to Harbor UCLA Hospital for treatment. She was released 9 hours later with a back brace and pain meds. The accident occured at 8:34 am Sunday April 5th, Easter sunday while on our way to church. Its been over a month and my wife is still in a back brace, but healing slowly. USB Drive taken out of the glove box showed that all cameras cut off about 10 seconds before the crash. Not sure if the whole system turned off.

On October 17, 2025, while using Full Self-Driving (FSD) mode on my 2021 Tesla Model S Plaid, the car failed to stop at two red lights within a three-hour period. In each case, the car attempted to drive through the intersection even though the signal was solid red. I intervened manually and applied the brakes to prevent a potential collision. There were no prior warnings or alerts, and I have not modified the vehicle. This behavior endangers my safety and the safety of others. I am willing to provide the vehicle and any available data logs for inspection if requested.

I have started receiving airbag & seat safety issue alert but recieved appointment after a month even considering major safety concern. Some of 2021 vehicles are serviced under the recall Tesla sent. But told me mine doesn’t qualify for same issue for same year, same model cars. It seems like issue is with all Tesla Model S 2021 but Tesla charging big dollar amount to repair the safety concern. They have also mentioned there is on going concern with air suspension and all Tesla starts giving problem between 60,000 miles to 90,000 miles. It costs around $6000 to fix that issue and told me these are not safety concerns.

Vehicle: 2021 Tesla Model S Long Range VIN: [XXX] I am reporting multiple safety-related defects that existed at delivery or developed shortly thereafter, and Tesla has refused to diagnose or repair them under warranty. These defects create an unsafe driving condition and risk of loss of control or collision. Defect Summary: 1.Alignment Defect at Delivery: On the day I bought the car, the steering wheel pulled to the left and felt unstable. I reported this immediately to Tesla. They dismissed it as “normal.” 2.Premature Tire Wear: Within months, the left tire wore down to the steel belts on the left side while the right side had normal wear. An independent shop confirmed this was caused by suspension/bushing issues, not road damage. 3.Suspension/Bushing Failure: A third-party Tesla-certified shop confirmed that the suspension components are bent/tweaked and require replacement for safe driving. Tesla refused to inspect these components properly. 4.Unlatched Rear Seat at Delivery: The rear seat was delivered unlatched, which is a major safety hazard during braking or collision. 5.Broken Glass Under Rear Seat: Broken glass was found under the rear seat cushion at delivery, raising concerns about vehicle history and delivery inspection standards. 6.New Defect While in Tesla’s Custody: On Nov 17, 2025, moisture accumulated inside the left taillight while the vehicle was parked outdoors at Tesla’s Stockton facility. This can cause electrical shorting or lighting malfunction. Tesla’s Response: Tesla has repeatedly refused to inspect the suspension properly, dismissed my complaints, and produced an inaccurate service invoice that did not reflect what was discussed. They told me we are “at an impasse.” These defects pose a serious safety risk (tire blowout, loss of control, lighting malfunction). I request NHTSA investigate these issues as they may indicate broader problems with Tesla’s suspension, alignment, and delivery inspection processes.

Front suspension has a popping and creaking sound when driving and turning steering wheel. Safety issue as sounds something is loose but Tesla says no issue it’s the body flexing which is even scarier to hear the panels rattling if this is in fact true. Tesla will not do anything about it. Additionally the brakes and rotors squeal when pressed at slow speeds coming to full hard stop. Both front and back. Both brakes and rotors have 90% life and according to Tesla shouldn’t need replacing until 90k miles due to the regen braking. The braking system does not engage as it should or how it is designed and car has 40k miles. Tesla uses the excuse that that they don’t cover this as it’s a wear and tear component. Which another issue because they don’t know the reason of why it’s doing this. They want customers to pay and replace the brakes and rotors. Many owners with same car experience this issue and is a design defect that can pose safety issues

Certified pre-owned 2021 Tesla Model S delivered on October 21, 2025 with worn Michelin Pilot Sport 4S summer tires (255/35ZR21 front, 295/30ZR21 rear). Tread depth measured approximately 2/32" on the outer tread shoulders of all four tires, below Tesla’s published 5/32" delivery standard. Within the first week of ownership, the vehicle hydroplaned multiple times in wet conditions at normal speeds. Tesla service declined to replace the tires, stating measurements were “taken in the wrong location” and that only the inner grooves count, despite Tesla’s public documentation and national tire safety standards defining tread depth across the full width of the tire. Vehicle was returned in same condition without correction, leaving a continued safety risk from inadequate tread and summer tires unsuited for Ohio’s cold and wet seasonal conditions.

I have a 2021 Tesla Model S Long Range with rear tire size 295 / 30 ZR 21. Both rear tires are worn so bad on the insides that the cords are showing. These tires were purchased and installed by Tesla along with a wheel alignment under 10,000 miles ago. The tires still look like new on the center and outside of the tire so I had no clue this was happening. The only way I became aware was because the low tire pressure warning kept coming on I started losing air slowly over the last month and thought maybe I had a puncture. The damage to the tire isn’t easily visible when just looking under the vehicle. I urge anyone with these tires to check them as it can easily result in a blow out.

Premature tire wear. Inside edges of rear tires wore out in 10k miles

NHTSA ID 11680711 · filed Aug 14, 2025

Have just learned (on routine check) that Front/Rear tire configuration has been backwards since delivery from the FACTORY; 24 mo, 24k miles. Factory specified FRONT REAR 255/45R19 285/40R19 NOTE REVERSAL Actual upon delivery FRONT REAR 285/40R19 255/45R19 ONLY service has been 1 left/right switch at 19k with NO front/back, per tire service recommendation; not detected then. And there’s NO chance it was reversed after delivery. I'm wondering effect on tread life, safety, drive-ability. Tech said this error would vastly affect performance, "Haven't you noticed car 'driving really funny'?" Notified Tesla; no response yet. In photos, Note door decal, fender placement will show front/rear.

The reverse lights are incredibly insufficient and pose a safety risk when backing up. The lights are so dim, they are virtually ineffective to the point that they illuminate nothing that may be behind the car. This is not a bulb issue as they came from the factory, new, in this condition and the service center said there is nothing they can do. Other owners I have spoken with report the same issue.

Passenger side headlight, daytime running light portion, is flickering, approximately 1-2 times a minute. I only noticed this as I parked in a dark garage with my lights on, seeing the light flickering against the wall. There is no warning from my car telling me this is happening. This is a safety issue because headlights are a safety feature. If my headlight is going on and off, it will affect my visibility, as well as the visibility of my car to other drivers/pedestrians on the road. I notified Tesla, they had mobile technician come to my house, he visually confirmed this issue, and he subsequently replaced the entire headlight. After the replacement, I noticed that this did not resolve the issue. I notified Tesla and they had me bring in my car to service center for inspection. Per tesla tech service summary: "identified customer concern as a known characteristic with no resolution available at this time. Please maintain regular WIFI connection to ensure timely downloads of future firmware updates. No repairs recommended at this time". I need this issue resolved, I do not feel safe driving my car. Tesla is not repairing the issue and has no clear timeframe as to when this issue will be fixed. I attached 2 photos from my video capture showing when the light is on and off.

7/30/2025 The vehicle experienced a confirmed TOTAL loss of function to include steering, restraint, and braking functionality at approximately 60 to 65 miles per hour. This catastrophic failure placed myself and and others at severe risk. Although Tesla’s service notes confirm the event occurred, no corrective repair was performed. The vehicle was completely inoperative with a matter of seconds with no prior warning. At this point in time the car has continued to not operate the same steering and noises has been in the shop 5 times still no answer or repairs in regard to it shutting down or any other issues that continue to return. The last visit I was asked to purchase new tires because maybe that’s why, I did. I continue to be told nothing is wrong with the vehicle making me feel extremely defeated when I know the vehicle is not the same as it was.

Front axle half shafts have failed two times requiring replacement (on 3rd set now). During acceleration the steering wheel vibrates violently. Tesla service center diagnosed both times that front half shafts needed to be replaced. There seems to be some design or manufacturing problem - these items keep failing. The cost to fix is ~$1,650 so I delayed as long as possible until vibration became unbarable. First replacement was done under warranty, second replacement was required ~16,000 later and I was forced to pay for it. There is a Tesla service bulletin about this which I saw online.
