In Nov 2019, while driving at night, the center touchscreen (MCU) of my 2015 Model S went blank and would not recover after restarts. I lost access to nearly all vehicle controls. The daytime running lights remained on, but the headlights did not illuminate despite being set to auto, and I had no way to turn them on manually because the headlight control is on the failed touchscreen. Climate control was inoperative and the windshield began fogging, reducing visibility. I could not open the charge port despite a low battery. I avoided the freeway and took local roads home. This is the failure covered by Recall 21V035 (8GB eMMC wear-out). Tesla service confirmed via diagnostic logs an internal fault within the MCU and replaced it with a remanufactured unit. I paid $2,045.47 out of pocket (invoice uploaded). The defect was not remedied. The remanufactured MCU contains the same 8GB eMMC; since the 2019 replacement the screen still goes blank 2-3 times per year, recovering only after 10-15 minutes of holding the reboot buttons. As of Aug 2026, NHTSA's VIN lookup shows Recall 21V035 as "Recall Incomplete": Tesla has never performed the free remedy (64GB eMMC daughterboard). Component available for inspection. In Feb-Mar 2021, Tesla notified me my vehicle was covered and invited a reimbursement claim per its NHTSA-filed plan (49 CFR 573.13). I submitted the claim through my Tesla account within the claim period. Tesla's portal confirms this: it displays "You have already submitted for the reimbursement" and blocks resubmission (screenshot uploaded). The plan commits to a decision within 60 days. Five years later: no decision, no payment. In Feb 2026, Tesla Support confirmed it has no mechanism to check or process reimbursement claims. I am reporting Tesla's non-compliance with its filed reimbursement plan and its failure to remedy this recall.
NHTSA complaint #11756104 — an unverified report by a vehicle owner.
This issue involves critical safety systems, including the rearview camera, front camera, and Autopilot/driver assistance features. The vehicle was taken to Tesla for a recall related to the MCU system. Tesla marked the recall as completed, but no effective repair was performed. The rearview camera remains unavailable, the front camera system is not functioning properly, and driver assistance features continue to be disabled. Tesla returned the vehicle without resolving the safety issue. This condition poses a serious safety risk, as essential visibility and safety systems are not operational despite a completed recall.
NHTSA complaint #11730301 — an unverified report by a vehicle owner.
My 2016 Tesla Model S (45,500 miles) is experiencing a complete failure of the Media Control Unit (MCU1), resulting in a total loss of the rearview camera display and defrost/defogging controls. This is a critical safety hazard. The unit was previously replaced by Tesla in 2021 under NHTSA Recall 21V-035. However, this replacement part has failed again after only a few years of low-mileage use. Tesla Service is refusing to provide a free repair or a goodwill discount for an MCU2 upgrade, claiming the 'recall repair' only had a 1-year warranty. It is unacceptable that a safety-critical component replaced under a federal recall fails twice in 45,000 miles. Tesla has failed to provide a permanent fix for the eMMC defect identified by NHTSA. By refusing to restore the camera functionality without charging full price, Tesla is knowingly allowing a safety defect to persist. I request an investigation into these premature failures of recall-replaced components
NHTSA complaint #11711765 — an unverified report by a vehicle owner.
I am the current owner of a 2014 Tesla Model S equipped with MCU1. While driving, including at freeway speeds, the center touchscreen has rebooted unexpectedly, showing only the Tesla logo before recovering. During these reboots, critical vehicle functions are unavailable, including the rearview camera, HVAC/defrost controls, and other essential features. This failure matches the exact safety defect described in NHTSA Recall 21V-035 related to the MCU/eMMC failure. I reported this safety issue to Tesla Service and provided photo evidence of the screen rebooting while driving. Tesla has refused to address this as a recall or safety repair. Tesla claims the recall was previously completed under a prior owner but refuses to provide any documentation proving that the recall repair was actually performed, citing prior owner privacy. Tesla has further stated that diagnosis of this active safety defect would be customer-paid due to the basic warranty being expired and has indicated that the only path forward is a paid infotainment upgrade. Tesla is effectively requiring payment to diagnose and resolve a known safety defect. As the safety defect is actively occurring while driving and Tesla has marked the recall as complete without providing proof or correcting the issue, I am requesting NHTSA review whether Tesla is improperly closing out recalls without ensuring the defect has been remedied and whether charging customers to diagnose known safety defects is appropriate. After entering my VIN into NHTSA’s recall lookup, NHTSA shows Recall 21V-035 (MCU/eMMC failure) as Recall Incomplete for my vehicle. This directly contradicts Tesla’s claim that the recall was previously completed. Tesla has refused to provide documentation and is requiring paid diagnosis and a paid infotainment upgrade despite the recall being listed by NHTSA as unresolved.
NHTSA complaint #11705673 — an unverified report by a vehicle owner.
After a recent Tesla firmware update, the backup camera (FMVSS 111 rear visibility function) stopped working. When shifting into reverse, the display shows a black/blank screen instead of the required rearview image. However, the rear camera preview feed still functions, indicating the camera hardware is intact and the failure is likely in the MCU/deserializer routing or software handling of the reverse camera mode. Tesla Service refused to investigate the firmware or signal-routing path and instead recommended a full MCU replacement at my expense without providing diagnostic logs or evidence that the update was not the cause. They closed the case and declined further review while the federally required safety feature remains inoperative. This appears to be a software- or firmware-triggered failure of a federally mandated safety system following a Tesla-pushed update, and I request NHTSA review.
NHTSA complaint #11701794 — an unverified report by a vehicle owner.
The main touchscreen (MCU1) and instrument cluster on my 2014 Tesla Model S frequently freeze, reboot, or go blank while driving. When this happens, I lose access to defrost, turn signals, backup camera, and speed display. I contacted Tesla Service, but they refused to repair or replace the unit under recall EA20-003 or the extended warranty, even though the symptoms match the known eMMC 8GB memory failure. The black screen and frozen instrument cluster create a clear safety risk. Tesla should cover this issue under the recall or provide an equivalent MCU2 replacement if MCU1 parts are unavailable.
NHTSA complaint #11695537 — an unverified report by a vehicle owner.
The contact owns a 2018 Tesla Model S. The contact stated that whenever the rear door was opened, the window on the door rolls down approximately a half inch, and whenever the door was closed, the window automatically rolled back up. The contact stated that after the rear door was opened to place some leftover dinner in the rear seat, the contact closed the door and his finger was caught in between the window and the door frame. The contact was concerned and stated that there should be a sensor to prevent such a failure and any injury while closing the door. The contact stated that his finger was bruised and cut and was bleeding profusely. The contact removed his finger as quickly as possible, preventing even more injuries to his fingers and hand. Medical attention was not needed; however, the contact did clean and bandage the finger after arriving to the residence. The dealer was not informed of the failure. The manufacturer was not made aware of the failure. The failure mileage was approximately 110,000.
NHTSA complaint #11692063 — an unverified report by a vehicle owner.
Tesla originally confirmed issues with the MCU1 system in my vehicle and upgraded it to MCU2. I Paid $1,599 for the repair/upgrade. Since then, the center screen has continued shutting off while driving. When this happens, the instrument cluster and controls go dark, I cannot see my speed, use the blinkers to signal, operate the AC/defroster, or access other critical vehicle functions. This has occurred multiple times on highways, including US-22 in New Jersey, which created serious danger because I could not monitor speed or signal properly. Although Tesla addressed the MCU1 problem by upgrading me to MCU2, they told me afterward the vehicle was still “safe to drive,” despite the failures continuing. I believe this is unsafe because I lose visibility of all driving information and access to basic controls. Tesla now refuses to repair these ongoing problems. After I raised complaints about the severity of the issue, I was dismissed and mocked for my speech disability during phone calls, and Tesla placed me on a service restriction. As a result, I am unable to obtain further repairs for this safety defect. I am afraid to drive the car. No Adaptive Cruise Control, Automatic Emergency Braking, Blind Spot Warning, Forward Collision Warning, Lane Departure Warning, Lane Keeping Assistance, Parking Collision Warning, or Rear Cross Traffic Warning features were involved in this failure.
NHTSA complaint #11682696 — an unverified report by a vehicle owner.
The contact owns a 2014 Tesla Model S. The contact stated while driving at various speeds, the digital screen intermittently blacked out and several safety features were inoperable. No warning light was illuminated. The vehicle was taken to a local dealer, where it was diagnosed and determined that the resort block remained at 90%, and the same EMMC ID that should have been covered under NHTSA Campaign Number: 21V035000 (Back Over Prevention, Visibility, Exterior Lighting); however, the VIN was not included. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 100,000.
NHTSA complaint #11680333 — an unverified report by a vehicle owner.
Tesla’s automatic wipers are unreliable. This vehicle lacks a dedicated rain sensor and instead uses the forward-facing camera and neural net to detect moisture. In light rain, the system often fails to activate. More critically, it frequently triggers false wipes during dry conditions—sometimes multiple times per day. Each dry swipe smears debris (e.g., bugs, sap), reducing visibility and risking permanent windshield scratches. This directly compromises driver safety and optics for the FSD/autopilot system. Tesla has acknowledged the issue but suggests turning off automatic wipers. However, this isn’t possible when FSD or Autopilot is active—they re-enable automatically. Proposed solution: If a wipe is triggered, the system should first activate the windshield washer. This would prevent dry swipes and maintain camera and driver visibility. The current logic is overly aggressive and lacks basic safeguards. Tesla must revise this behavior—both for user safety and hardware longevity.
NHTSA complaint #11675799 — an unverified report by a vehicle owner.
While driving at approximately 5 MPH, the front passenger side window spontaneously shattered without any external or internal impact. I was alone in the vehicle and no one was seated in the front passenger seat. There were no objects in the car that could have made contact with the glass, and there was no indication of any road debris or other outside force. The window failure caused microshards of glass to scatter into the cabin, creating a potential safety hazard to the driver and any possible occupants. There were no warning lights, alerts, or symptoms before the failure occurred. The vehicle was inspected by a manufacturer service center, but the request for an engineering-level inspection was denied. The service center did not identify any external cause for the failure but still refused warranty coverage and did not escalate the issue for further analysis. The issue has not been reproduced but has not been properly investigated by the manufacturer either. Given the complete absence of impact and the sudden nature of the failure, this appears to be a glass defect or an installation issue. The broken component is available for inspection.

The driver side rear view mirror vibrates at most speeds in a way that renders it useless. This is a well described issue. Tesla is aware of it but refuses to fix it. It renders the mirror useless at some speeds.
NHTSA complaint #11638946 — an unverified report by a vehicle owner.
The contact owns a 2021 Tesla Model S. The contact stated while the vehicle was parked, the message “Climate Control System Service Required” was displayed. The contact stated that the vehicle was taken to the local Tesla Service Center however, the vehicle was not repaired due a lack of available Service Techs. The vehicle was not repaired. The manufacturer was notified of the failure but offered no assistance. The failure mileage was 59,000.
NHTSA complaint #11630460 — an unverified report by a vehicle owner.
Experienced severe phantom breaking on [XXX] in route to Las Vegas at 70mph September 2024. In heavy rain, while windshield wipers set to auto...........wipers have stopped momentarily blinding the driver, a problem Tesla hasn't fixed on my neighbors 2019 Model 3. The stalkless design prevents safe use of turn signals, horn and gear shifts. Wife who only drives an ICE car can not safely operate turn signals, horn and gear shifts in my 2023 Tesla Model S. Camera system constantly renders 'Blinded' error messages halting Autopilot features. Tesla's resolution is to clean camera's before initiating Autopilot.

NHTSA complaint #11620970 — an unverified report by a vehicle owner.
Tesla removed the blinker stalk and replaced it with capacitive buttons on the steering wheel. This is very dangerous because the buttons move as you turn the wheel. To make it worse, they used capacitive buttons that are not raised so sometimes the ONLY way to turn your blinker on is to look away from the road and at the steering wheel to find the button. The buttons would be more useful had they simply been a rocker button like a lot of vehicles have on their steering wheel for volume control of the radio. But the real problem is that on multiple occasions, the turn signal button simply does not work. They do work 99% of the time but there have been several occasions where I have pressed the capacitive button and the blinker does not go on. I then have to look away from the road to confirm I am pressing the button but it still does not work. On a couple of occasions, if I press the other blinker button and then press the original blinker button, it will work. Other times if I press it enough times (i.e. over 5 times), it will then work. After the 1st complaint, Tesla replaced the component but it continues to happen. I believe it is a software bug and despite seeing other people report this problem to the NHTSA, Tesla told me no one else is reporting it. They suggested when I pick up the car that they show me how to press the button. What is more likely, that I don't know how to press a button or that there is a problem in their design? I know there is probably no rule against not having a blinker stalk because why would anyone ever design a car that would have moving buttons on a steering wheel but I think it is time for a rule and to require Tesla to fix this. If you can't require a blinker stalk, which would be the correct fix, then require the buttons to not be capacitive and to be raised. And who would design left and right buttons to be one on top of the other instead of being side by side. Terrible design and very unsafe.
NHTSA complaint #11615735 — an unverified report by a vehicle owner.
There is a design flaw in the functionality of the windshield wipers. Instead of the functionality being on a stalk like every other car, Tesla decided to make it a 2 step process. To operate the windshield wipers, you first have to press a capacitive button on the steering wheel and then you have to scroll a wheel on the steering wheel. The first problem is that the button to turn on the windshield wipers is a capacitive button that is not raised on the steering wheel - so the button moves as you turn the steering wheel and thus it is not in the same place all the time. This makes it very difficult and practically impossible to find the button without taking your eyes off the road to find the button on the steering wheel. The second problem is that once you find that button, you then have to find the scroll wheel on the other side of the steering wheel to then adjust the speed. So picture you are driving into a downpour. You instantly can't see because of the rain. Because you are turning slightly on the highway, you have to take your eyes off the road to find the button on the steering wheel. That will activate the wipers but only in intermittent mode. You then have to use the scroll wheel on the other side of the steering wheel to adjust the speed so it is continuous. And while the car does have an "auto" mode, I've owned 3 different Teslas over 9 years and it has never worked properly - often turning on the wipers on a day that is 100% sunny. The auto mode also doesn't work well when it is raining because it often doesn't sense the correct speed (so staying in auto mode is not a great solution). The correct solution would be to return the wiper functionality to a stalk on the steering column and most definitely not require 2 separate buttons/functions to use it. It is very dangerous having to take your eyes off the road when you enter a downpour or when you are in a drizzle situation and then it starts pouring because you need to do 2 things.
NHTSA complaint #11615738 — an unverified report by a vehicle owner.
I received a letter from Tesla in Jan 2024 detailing recall 24V-035 for my Model S 2023 vehicle. This recall indicates the vehicle is not in compliance with FMVSS No. 111, S5.5.3. and promised an over-the-air software update to remedy the issue. However, it is now June 2024 and my vehicle continues to show no updates are available to fix this safety issue. My vehicle continues to run software version 2023.44.30.6 while the fix is only available in version 2023.44.30.7 and later. I am concerned the Tesla is either incapable of fixing the problem via software updates and is dragging its feet, or lacks the expertise to fix the problem via said software update.

Windshield with distortions causing driving distractions and headaches. I am on my third windshield with the same problem. This seems to be a widespread issue in reviewing online forums.
NHTSA complaint #11591841 — an unverified report by a vehicle owner.
My new car has severe distortion of the windshield and the tailgate glass which could make driving the car unsafe by distorting the lane markings, cars and streets, and/or by inducing dizziness. I took the car to Tesla service and was told that the issue is within specifications and that all other similar Teslas have the same glass issue and replacing the glass would not help the issue. It seems that the glass supplier that Tesla is using has a poor manufacturing quality. The company does not seem to care. I hope you can investigate the issue and request that Tesla address the defective glass with the current supplier or switch to a better quality supplier.
NHTSA complaint #11587563 — an unverified report by a vehicle owner.
The MCU that controls the climate and Advanced Driver Assistance Systems stops working while driving. I sent a service request to TESLA and they replied that my older MCU1 is failing because of the new software updates. It isn't the eMMC card hardware failure, but the symptoms and safety concerns are the same. None of the controls work, as the main screen goes blank and resets while driving. TESLA told me the fix for this problem is to upgrade to MCU2, which they fail to provide for free as a safety recall. There was already a recall for the MCU memory chip failing and causing the same safety concern. The car disables the Advanced Driver Assistance Systems when this problem occurs. It happens about once or twice a month for the last year.
