What happened? while driving my 2015 Tesla Model S, the main touchscreen (mcu) began intermittently going black, disabling access to essential vehicle controls, navigation, climate settings, and rear-view camera display. At times when the mcu was functioning, the rear-view camera feed would still display a black screen upon shifting into reverse, leaving me without any rear visibility. Component or system that failed: media control unit (mcu1) / emmc memory failure rear-view camera and/or associated wiring harness safety risk: the intermittent blackouts of the mcu and loss of rear camera feed created significant safety hazards, especially when reversing or attempting to adjust driving settings while in motion. The loss of rear visibility increased the risk of collision with pedestrians, cyclists, or obstacles. The mcu failure also limited access to defrost/defog controls and turn signal audio feedback. Problem reproduction and confirmation: Tesla service has confirmed both the mcu1 hardware failure and the rear-view camera malfunction. The problems occurred repeatedly before being inspected. Inspection: the vehicle has been inspected by Tesla service center technicians, who diagnosed both the failing mcu1 and the defective rear-view camera. Warning messages or symptoms prior to failure: for mcu: slow system performance, frozen screen, then intermittent complete blackouts while driving. For rear-view camera: black or distorted camera feed when in reverse, even when the mcu display was otherwise operational. These issues began occurring in June 2025 and became progressively worse until Tesla inspection on July 6, 2025.

My driver's side of the vehicle looks like it's melting. I was informed by the service advisor at Tesla that this is a common issue, and the computer needs to be replaced at my expense.

Today while driving the screen behind the driver steering wheel suddenly shut off and went black. I was unable to see if I am in drive or reverse or what my speed is.

The instrument cluster freezes and has to be reset. When it freezes you have not knowledge of speed you are going. After bringing it into Tesla service I was told that is a known defect. The only way to fix is to replace infotainment system at a cost of $2,100. Infotainment system currently works fine. The rep informed me that the system does not have enough memory to run the computer correctly after all the updates that Tesla makes you install.

My instrument cluster goes off while driving making it impossible to know my current speed. It also will cut off when I put it in park and the car will not move until it completely reboots. Sometimes it will just freeze and say the car is off and in park while the car is in drive moving. One time the cluster showed that the car was in reverse but when I hit the accelerator, car moved forward. Cluster is constantly rebooting itself. 2014 Tesla models s 85. I have an attached video where all warning signs are illuminated,no speedometer and shows its in park while im driving.

The cable harness (slip ring) connecting the steering wheel controls including the vehicle horn, steering wheel buttons, scroll wheels, and potentially the airbag (according to the service technician) failed on this vehicle in January 2025. The vehicle was inspected by Tesla’s mobile service and they acknowledged that the cable harness had indeed failed. It is available for inspection. We have been forced to drive this car without a functioning horn and airbag. There were no warning signs or messages on the vehicle computer.

The screen abruptly shuts down and that is a safety hazard. Tesla has refused to fix this issue.

Tesla instrument cluster screens are leaking fluid and eventually failing. The instrument cluster is the only place I can see my speed, thus my car is now unsafe as I can not tell what speed I am driving at.

Component failure: the Tesla nema 14-50 charging adapter for my 2016 Model S malfunctioned, causing overheating that melted a prong and led to an electrical fire. The defective adapter appears identical to those in Tesla's November 2016 recall, though mine was designated "not affected. " the damaged adapter and charging cable are available for inspection. Safety risk: this malfunction created a serious fire hazard endangering myself and my property. The electrical fire damaged both my vehicle and charging equipment, and the fire could have spread to my home, potentially endangering my family and neighbors. Verification: I took the damaged adapter to the Tesla service center in colorado springs, where technicians acknowledged the damage but refused to replace it under the recall. They visually confirmed the melted prong and fire damage. Manufacturer response: after the incident, I contacted Tesla corporate requesting replacement of the defective equipment. They responded that they don't believe the electrical fire was caused by the defective plug, despite physical evidence showing the same issue as recalled units. Warning signs: prior to failure, I noticed intermittent charging interruptions and the adapter becoming unusually hot. These symptoms began approximately three weeks before the fire incident. There were no dashboard warnings about potential charging equipment issues.

On [xxx] at approximately [xxx] I was driving down a small back alley/street in baltimore when my Tesla Model S plaid sedan stopped operating. It would not restart, including with the emergency restart bar. Since I was unable to restart it, I left it there while I ran into an appointment. About maybe 20 minutes later it started up like nothing was wrong. I did not receive any warnings on the dash from the car that there was an issue, and I thought it must have been a computer glitch. Unfortunately, sometime between 10:30 and 11:30 am I was driving the Tesla on a major feeder multi lane feeder branch to a highway. I was on [xxx] merging onto [xxx] when the car just stopped with no warning. It is a miracle that I didn’t get hit, but it caused a truly dangerous situation with horns blaring, cars and trucks going around me. It was very unsafe. This time I was able to start the car with the emergency start bar Tesla has available. I was then able to drive the car to my office where the car was picked up and towed to the dealership. To make a long story short, apparently, they (service department) drove the car around the parking lot, trying to reproduce the problem but they said they were not able to. The only thing they were able to tell me about the car was that it had two high-voltage spikes and possibly that’s what caused the problem, but they didn’t know how to fix that problem. I did talk to the lead tech on my car, but at one point he said they were out of resources and would refer this to his general manager. The service manager told me that since they can’t reproduce the problem, that my car is drivable, I should pick it up and drive it. I refused. A car that stops dead with no notice in moving traffic is not a safe car. I was astounded that they would expect me to drive the Tesla. I told the manager that I would not drive it until it was fixed. It is still there. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

•I’m not sure what component was responsble for either the braking issue or the fire. It is available for inspection. •when driving the brake pedal had a frightening delay that almost caused 2 accidents and unfortunately my car was charging on the 24th of October which could have something to do with arching that led to my garage catching fire rendering the car unable to move or turn on after the incident. I’ve insisted Tesla insurance to look into possible causes because the fire dept. Mandated the a ladwp (power company) to install new transformers to our power supply a couple of days after the fire, which they did. Tesla insurance seems uninterested in finding the cause and wants to compensate me for the vehicle but I believe it’s in their best interest to find a cause and document it. The car had no issues prior, in fact the service center sent a mobile tech to replace the 12volt battery on the car not even 10 months ago. After the fire the car died and has a bunch of codes that make it inoperable. • service center rejected looking at it because of the risk. They said since it was possible salvage they could not look at it which is understandable but they worked on it before in decem •insurance has been unwilling to look at any of this they just want pictures of the car to settle the issue. In my opinion they are ignoring a bigger problem. Tesla is my insurer. •the car had no issues prior to the fire and none during the near misses were the brake delayed.

See attached document for complaint.

Overnight while plugged in and after the battery showed it was fully charged, the battery suddenly lost charge, and the car sent repeated alerts to immediately pull over and stop driving. A notice on the car showed mileage was reduced and to immediately schedule a service call. After returning home, I downloaded to the car a recent software update that cleared the error. However, after the software upgrade, Tesla messaged that they did removed tests and the high voltage battery must be replaced.

My Tesla Model S 2022 unexpectedly shut down while parked in a covered garage on [xxx], after I had driven for an hour. This occurred after I returned from a family trip to lima, peru, where I did not use the car. Tesla service center diagnosed it as water damage requiring a $20,578. 50 battery pack replacement, which was covered by my insurance. There were no warning signs prior to failure. Within 20 minutes of the tow truck dropping off my car at Tesla, a representative informed me it was water damage, citing a system error and claiming over 20 vehicles had the same issue. This suggests a widespread problem and Tesla's awareness of it. This incident raises serious safety concerns about a potential design flaw and the lack of a water intrusion warning system. If this occurred while driving, it could lead to a sudden loss of power and an accident. I urge the NHTSA - investigate if a design flaw exists in the Model S 2022. - investigate Tesla's awareness of this issue and their failure to implement a warning system. - require Tesla, and all ev manufacturers, to submit water mitigation plans. - mandate water intrusion detection and warning systems in all evs. This incident highlights a critical safety risk for Tesla - and perhaps all ev - drivers, and I urge the NHTSA to take immediate action. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

My Tesla was parked unlocked in my garage. I came out to drive it and all the doors were locked and would not open with my key card. It also would not unlock with my cell phone app. Tesla customer service also could not remotely unlock it. The vehicle had to be towed to a Tesla service center where they forced open the window to gain access. They stated the car needed a new control panel. I have read where Teslas have locked up with children in the car and parent could not gain access to the car. These situations need to be looked into since the Teslas locking up are not isolated incidences.

Received and ota notice on the dashboard that states "battery fuse replacement" is required. The fuse is due to a li-ion battery that wears out for a safety system. Life expectancy of the battery is 10 years. It has not lasted 8 full years. This is stated as a safety issue and Tesla has since redesigned this item to not required the batteries. I have alerted Tesla about this issue, have not had a reply, as yet. The vehicle can be operated without this safety device, which seems inappropriate. I feel this should be replaced under warranty and/or recall - but it appears Tesla will want to charge an excessive amount of money.

On 04jun2024 at approximately 1230 pm my husband loaded my 4 year old child into the car. He shut the door then tried to open the driver site door. At that time the inside the car was 93 degrees. The car shut off. Telsa customer support was contacted multiple times. My husband expressed the urgency multiple times that there was a child under 5 who was stuck. There was no urgency with telsa. We were told to contact 911 if we wanted to get our child out. There is no way to manually open the Tesla Model S door from the outside. At approximately 1300 911 was dispatched and the window was broken at 1330. The internal temperature of the car was approximately 110 f. She was assessed by the firefighers and determined that she did not need to go to the hospital for observation as my husband is a medical professional and her temperature was not severe enough to warrant observation. The sent a tow truck that arrived at approximately 1345. Tesla did expedite the tow truck. We were told multiple times there is absolutely no way to open an Model S door manually from the outside. And given no options. We informed them we were at our house and had multiple tools. However we were unable to break the window on our own and had to call 911. My car was at the dealership 23may2024 and shut down had not occurred prior to this, nor was this noted as a finding after the mainentance.

I took my car to the dealership to have the mcu1 recall performed because my behind the steering wheel monitor and center touch screen monitor kept turning off and reseting while driving. When this happened I would lose the ability to see my speed or view my back up camera. The recall was performed and the problem was not fixed. The screen does not turn off as often, but it still regularly happens. I contacted Tesla to let them know the problem remains and they want me to pay $1750 to upgrade to the newer mcu2.

Lcd dashboard is bubbling and liquid seems to be leaking within the dashboard screen. In some online research, there are concerns that contaminants can infilitrate the cabin when this happens. The problem seems to be pervasive for cars made by Tesla from 2012 to 2014. There were no warnings for when this problem ocurred. Tesla is saying that the part needs to be replaced at a cost of $1900.

I was driving on the dallas north tollway (dnt) northbound to for a work meeting on Monday, April 22, 2024, at about 3 pm (central). My 2018 Tesla Model S shut down while driving on the freeway. The power steering went off and so did the hazard lights. I pulled over to the shoulder. Unfortunately, the shoulder is not too wide on dnt. I was driving at 70 mph or so when this happened. The only warning that popped on the Tesla screen was “vehicle shutting down pull over safely”. The battery still had about 175 miles left to empty. So, this was an unusually unsafe incident that could have been life threatening.

The contact owns a 2016 Tesla Model S. The contact stated that while driving at undisclosed speeds, the instrument cluster became inoperable on several occasions. The contact stated that the failure had occurred several times. The vehicle was taken to the dealer; however, the contact was informed that the failure would reoccur unless the vehicle was updated with a new infotainment center and a faster processor. In addition, the contact stated that the vehicle had been taken to the dealer several times due to the failure. The contact stated that recently the instrument cluster and the ecm were replaced. In addition, the vehicle recently received a software update. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 73,000.

Frunk latch does not open with the first tap due to misdesigned frunk liner trim piece. The only way to open the frunk is after first tap to simultaneously tapping open and pulling the hood upward. It is only feasible using the phone app as the vehicle comes with key-card. This creates a safety concern due to fire crew would have an issue reaching a first responder loop to disconnect a battery located under the hood in case of an accident. The issue was reproduced to Tesla service team but they claimed that it is yet impossible to repair.

The component that Tesla has stated is the part that is failing is the mcu (media control unit) which was a recalled part at one point but then Tesla decided to replace only a single part of the mcu which was the emmc (embedded multimedia card). Luckily the vehicle was not driving when it completely shut down and would not start back up but I was stuck in a restaurants drive-thru for roughly 4 hours till I could get a tow truck to come tow it. The tow truck had to put the car on dollies as the vehicle would not enter tow mode nor would it enter its emergency neutral mode so the vehicle could be moved. The windows would not go up or down and luckily the trunk was able to open because if not then I would have been stuck outside my vehicle as the door handles did not come out after I got out of it and closed the door behind me. Please read the messages from the tech as you will see that they tried to act as if they did not know what was going on with my vehicle but then I asked something else and they stated exactly what the issue was but supposedly could not confirm it was that unless they charged me a diagnosis fee and "got hands on" which I'm sure that info of what was wrong with my vehicle was nothing they needed to get their hands on. There were no warning lamps or messages until the vehicle shut off on me in the drive-thru and then the warnings started to populate staying that the vehicle was off, vehicle could not detect brake being pressed, and that the vehicle was not detecting the key. The repair estimate is no longer available in my app for some reason, probably because I did not repair the vehicle as they were wanting me to upgrade to the new mcu that is in the current vehicles and it would have been roughly $2,400. 00. Just today, the vehicle would not start, would not move my seat or anything to its memorized position when I got in the vehicle and the screen was frozen, just as it did when the original recall happened of the mcu/emmc, photo/videoattached.

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.

The window will not go down either due to software, electrical or hardware issues. The window motors have gone out had have had to be replaced. Likely, another motor has failed. In the 2015 Model S in order to open the door the window must lower an inch or more to clear the door frame. When the window will not lower due to software, electrical or hardware issues, the door is difficult to open and may crack/break the window. The is a safety issue getting into and out of the vehicle. The most recent issue is dated below. There have been other issues previously.

The blinkers on the steering wheel inadvertently stop working from time to time causing a dangerous situation for myself and the drivers around me.
