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)

Vehicle constantly overheats and causes charger to overheat. This causes the charging rate to reduce constantly. Home infrastructure has been checked and confirmed to be wired properly by multiple electricians. The suspension makes lots of noises and is a rough ride despite being constantly checked by the service center.

See attached document for complaint.

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

The horn is a small button in a very small area of the steering wheel. The center of the steering wheel which acts as a horn on almost all other vehicles, does not work. In the event of an emergency, and the horn needs to be activated, it is difficult to find and press the small button, and the instinct would be to press the center of the steering wheel, which would not work and the horn would not activate.

The instrument panel (screen) goes blank for approximately 5 seconds while driving. This issue happens at random. It has happened while on city streets, the highway, and in parking lots. Because of this issue, I cannot see my speed, the visualization of the car and surroundings (blind spot or pedestrians), any warnings that may pop up (such as an issue with the Autopilot or Full Self Driving Beta), nor any lighting or wiper information (for auto high beams and auto wipers). Tesla says it is a known issue, and it is software related, but there is no timetable for a fix. They do not believe a replacement screen/components will have any effect, so they are not offering any type of fix.

I was unable to locate the horn capacitive button on my steering yoke to alert a biker who strayed into my lane. finding this small button has been a repeated problem when in dangerous situations

My safety concern is with the 17 inch screen. Originally in the information about the car before it was purchased, the manufacturer said that the screen would tilt left or right to give the drive better a better view and access to the touch screen. I have talked to service about this issue and they have said they do not plan to retrofit our cars with the motors to make the screen move. This is now working on the same car that is one year newer. We were promised this and I believe this issue with the screen not moving is a serious concern. You cannot see the screen as well or touch it as well because it does not tilt towards the driver. Please investigate this problem, it is dangerous.

While driving with a fully charged battery, the car dash warned “pull over to safe location. Battery cannot support all functions”. We were unable to fully pull over in the time before the car experienced a critical loss of functionality, as the car shut off in less than 1 minute from flashing the warning. The car lost all functionality, including loss of its flashers, putting us at significant risk since we were unable to alert other motorists to our presence on the side of the road as it was getting dark. The car is currently with the dealer and thus far they have been unable to identify the root cause of the issue but have acknowledged the existence of the problem. They’ve claimed the 12v battery died and the car does not have any safety redundancy built in to be able to access power from the main driving battery to power critical features such as the hazard lights. The biggest risk of safety is loss of indicators/flashers while on the side of the road. This feature in vehicles is meant to alert other drivers to the presence of a disabled vehicle. Consumer was told no physical problem was found with the car and a “firmware” problem is suspected. After repeated questioning, the Tesla dealer finally acknowledged that other 2021 Model S cars have experienced similar abrupt shut downs and the California engineers are aware of the problem. They cannot tell me when a firmware update will be available, but in the interim want to return the car to the consumer having done nothing to prevent the problem from recurring.

The emergency flashers are a capacitive touch button. It does not reliably activate. I have tried on multiple occasions with a cold cabin, warm cabin, clean and dry fingers, warm and cold fingers and I rarely get the flashers to turn on within 5 tries.

The start up chime that dings when the car starts plays CONTINUOUSLY while the car is driven. This is not only distracting, but it prevents the driver from hearing the other dings that are associated with the safety systems (collision warning, lane departure, etc.). I have videos available but am unable to upload a video via this online complaint system.

HVAC system malfunction. On January 15, 2022 this brand new car, on its first day of ownership with 750 miles, suffered a malfunction with the heating and cooling system such that it no longer works and displayed the following warning: "VCFRONT_a447 - Cabin climate control system requires service - Cabin heating / cooling limited or unavailable." As a result, the car becomes unbearably hot during the day in the South Florida heat and unbearably cold on nights when the temperatures dip. This is a safety issue that should be investigated by the NHTSA.

The rear passenger side Adaptive Suspension wiring harness was either installed improperly or routed improperly and rubbed against the inside of the tire. After many miles, this harness was worn down to the point of breaking electrical contact, which puts the vehicle into a fallback state. When the dampers are disabled, the car becomes floaty and disconnected and is dangerous to drive. There were warnings in the system immediately when this broke. It is available for inspection, as Tesla has stated they cannot fix it for 6 weeks. The problem has been confirmed by their service dept via remote diagnostics. There has been no inspection by anyone other than myself, however I have extensive photographic evidence. The issue is very obvious when you know to look.

This was a Autodrive malfunction event on a brand new Tesla Model S. I was in standstill traffic when my car, which had been engaged in Autodrive, lurched forward and suddenly accelerated at a high rate of speed into the car in front of us, without any driver prompts. The problem was immediately reported to Tesla who has been delaying in providing the data logs and engineering analysis for over two months. Tesla did what they called a "safety inspection" after the crash and says the car is fine. They have refused to try and replicate the malfunction because they maintain the car is fine. Luckily, no one was injured, and there was only property damage to my car and the car in front of me, but there is something wrong with the software, the cameras, and/or the front end sensors and their calibration for the car to have done that.

There have been 4 instances of the instrument cluster screen and main information touch screen shutting down while driving the vehicle. First 2 episodes were in Aug of 2021 then twice in Oct of 2021. Episodes were separated by 1-2 weeks. Both screens are blank for approx 20-40 seconds. Subsequently no information such as speed, brake light indicators, radar/hazards, turn signals or any other information is displayed or can be used. Unknown if the turns signals or brake lights work when this happens as there is no way to see them on the blank screen. No clicking sound for the turns signal is audible either. Car continues to operate otherwise. Both screens then come back on without intervention and all functions return to normal. I have spoken with Tesla service and they state they are aware of this problem but they don't have a fix. They ran remote diagnostics but did not see any abnormalities. They also suggested that my USB drive to record the vehicles security/driving cameras was corrupted and may be causing the problem however I have not set up the USB drive in this car yet.

My car has a « yoke » steering wheel that feels unsafe and should be illegal along with the touch turn signals and horn. I almost crashed today when I had to swerve to avoid a mother crossing the road with her child. I tapped on the honk, but unfortunately, it’s not in the middle of the steering wheel as one one would expect, but it’s a small touch button right next to the cruise control touch button. each time i need to engage it, I have to take my arms off the road and find this button. It’s very distracting, especially in emergency situations. The turn signals are also « touch » only and there’s no way to really know if you have them or not. When turning in a roundabout, the yoke steering wheel is almost upside down and trying to signal is nearly impossible. I think the yoke steering wheel and touch buttons are marketing gimmicks used to get people to talk about Tesla at the expense of the safety of the owners and other innocent users of the road. This is extremely dangerous in my opinion and I’m now officially scared to be driving my car. Please make Tesla recall these cars and retrofit a normal steering wheel with a regular horn and stalks for the turn signals. Thank you for reading you are our only hope.
