The contact owns a 2019 Tesla Model 3. The contact stated that his wife was driving approximately 30-40 MPH at night with Full Self-Driving(FSD) mode engaged. The contact stated that the driver was exiting the highway to merge onto another highway that would close intermittently. The contact stated that the driver briefly looked at the navigation screen, and the vehicle suddenly crashed into the first highway closure gate, and the windshield shattered. The vehicle then crashed into a second highway closure gate. The contact stated that the Full Self-Driving(FSD) mode failed to operate as needed to prevent the collisions. The driver was able to stop the vehicle by depressing the brake pedal. The vehicle stopped in the middle of the highway, and there was no oncoming traffic. The contact's daughter was occupying the front passenger's side seat during the incident. The driver called 911, and the police officers arrived at the scene. A police report was filed, but the police report number was not available. The air bags did not deploy. There was no injury sustained. The vehicle was towed to a tow yard, where it was under evaluation. The contact related the failure to NHTSA Action Numbers: PE25012(Electrical System) and PE24031(Electrical System). The contact attempted to contact the manufacturer via phone, but the manufacturer was unreachable. The vehicle was not repaired. The failure mileage was 111,725.

I am reaching out to report a high voltage isolation issue with my 2019 Tesla Model 3. Tesla determined the issue was caused by external factors such as grime and road salt corroding the battery seals, leading to an internal isolation fault with the high voltage battery. They deemed it out of warranty, with an estimated repair cost of $13,155.30. When I asked what preventative maintenance could have avoided this, Tesla only referred me to the owner’s manual, which simply instructs users to clean the car’s exterior. No specific maintenance regarding battery seal inspection or corrosion prevention was provided. Records from our local car wash subscription show the car has been washed regularly (at least 66 times since January 2024). The previous owner also had brake lines replaced due to corrosion under warranty, during which Tesla removed the battery in March 2023. In October 2024, the rear drive unit was replaced under warranty, yet no mention was made of battery seal corrosion during any of these service visits. At no point has Tesla’s maintenance guidance or service process addressed checking the seals for corrosion in regions where road salt is heavily used. I believe this omission creates a potential safety concern, as seal corrosion in a high voltage battery could lead to failures or hazards without prior warning. The Vermont AG Consumer Assistance Program recommended I contact your office for further assistance. This issue appears to be part of a broader pattern where Tesla attributes failures to “environmental factors” without advising owners of any specific preventative maintenance, effectively avoiding warranty responsibility while leaving potential safety issues unaddressed.

I am writing to express my serious concern and to file a formal complaint regarding a critical issue with my Tesla vehicle, specifically related to the Power Conversion System (PCS). I have recently been informed by Tesla’s diagnostic team that the PCS in my vehicle has malfunctioned and requires replacement. This is particularly alarming given the vehicle's relatively low mileage and my previous history of reporting charging issues. For your reference, the key details are as follows: Vehicle and Issue Identification: The vehicle in question, which I took delivery of in May 2019, is now experiencing a significant reduction in charging capability, only charging at 16A instead of the expected 32A. This issue has persisted despite earlier assurances that the problem was with the wall charger, a claim which now seems inaccurate. Mileage and Usage: My vehicle has only covered approximately 29,000 miles, which casts doubt on the wear-and-tear argument for such a critical component failure. Safety and Recurrence Concerns: While I am currently not aware of any direct safety issues, the recurrence of this problem among other Tesla owners is worrying and suggests a potential pattern of technical shortcomings. Cost of Repair: I have been quoted a repair cost of $1,808/- by Tesla, which is a substantial amount, especially considering the vehicle's age and mileage. Given these points, I request a thorough re-evaluation of this matter. I strongly believe that this issue should be covered under warranty, or as a goodwill gesture, considering the vehicle's low mileage and the history of charging issues reported shortly after purchase. Furthermore, I urge Tesla to investigate if this is a wider issue affecting more vehicles, as it raises concerns about the reliability and durability of critical components in Tesla vehicles. The vehicle is available for inspection at your convenience. I expect a prompt response to this complaint, and I hope for a swift and satisfactory resolution.

The contact owns a 2019 Tesla Model 3. The contact stated while charging the vehicle at a supercharging station, the vehicle shut off once the battery charge reached 250 miles. The contact attempted to move the vehicle to another charging station, and the vehicle failed to shift to drive(D). Due to the failure, the vehicle was towed to a Tesla Service Center where the contact was informed that the pyro fuse used to regulate the battery voltage had failed to operate as needed. The contact was also informed that the pyro fuse inside the vehicle was an aftermarket part; therefore, the contact would be responsible for the repair of the vehicle. The vehicle was not repaired and remained in the possession of the dealer. The failure mileage was approximately 85,000.

Twice in a span of six weeks my 2019 Tesla Model 3 simply stopped operating - dead stop. First incident was on a road trip over the Christmas holidays ([XXX]). We had stopped in suburban Chicago before continuing our trip home. The vehicle control screen went black and the vehicle ceased almost all operations. The vehicle could not be started nor put into a gear for towing. All functions accessed through the screen (virtually every function) was rendered inoperable. I called Tesla who told me that according to their computer systems the vehicle was active. The mercifully nearby service center said no fault was recorded by the computer log. They were able to get the screen reactivated and we continued our trip with no further incident and they weren't able to explain what happened. On Friday [XXX] the same thing happened in our garage. The vehicle was towed to Tesla. They diagnosed the issue to an electrical fault in the steering column which shuts the vehicle down. The remedy is a replacement of the entire steering column at a cost of $2100 plus labor. I don't know if this is a typical remedy for other manufacturers but this is quite a expensive solution for an issue unrelated to the steering function. From a safety perspective this was an astounding occurrence. If this winter was colder or we were in a more remote place we would have been in pretty big trouble not being able to activate the heat or any other function of the vehicle. I believe the totality of the shutdown makes this fault an extraordinary concern with an extraordinary price tag for Tesla drivers.

The local Tesla Service Center was contacted and informed the contact that the recall repair could not be performed on the vehicle due to the hardware of the vehicle. The dealer informed the contact that the recall repair required hardware 3.0; however, the vehicle hardware was 2.5. The dealer charged a fee to update the hardware. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue and made the same assessment. The contact had not experienced a failure. VIN tool shows no open recall.

Since Summer/Fall 2023, 2019 Tesla Model 3 software appears to have been compromised. The vehicle shows entirely incorrect directions, at times having taken me 24 miles out of the way; shows a Subdivision in Baltimore, MD named "[XXX] Heights" and a business in Woodbridge, VA named "David's [XXX] Pole Waxing"; has removed all charging stops at certain times and then showed all charging locations in a Metropolitan area as "busy", has rolled down windows at random in 17⁰ weather to the point of having to hold the window toggle up with one hand while driving, is operating windows in reverse; shows an overlay on the screen where the white speed limit sign sometimes changes the size of the square; shows an overlay on the app, and has at times locked me out of the car entirely (seemingly remotely). The heated seats had overheated at other times and had left burns on my back. Tesla denies that the software and/or app have been compromised and claims that the currently-installed software is the original factory software without having inspected the car. Tesla twice now has declined to inspect it. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

After leaving my neighborhood, my car stopped working while I was turning. Everything went black, and I was unable to turn my hazards on and had to exit the vehicle using the emergency lever to open the door. The car was towed to Tesla. It had to be forced onto the tow truck, as you can only shift the gear to neutral if the car is on. We asked Tesla what the problem was in the service chat, and they said "Yes the rear drive inverter went out on it that goes to the rear drive unit." I have never heard of such a malfunction with Tesla. There was no warning to pull over. If this was on a highway or busy street, the car would have just died, which could have caused a major or fatal accident. This matter should be investigated promptly, as it is a major safety issue. There could have been a fatality if this had happened on a busy highway with speeding cars. When I say it stopped working without warning, I truly mean it. I was unable to turn on my emergency lights. The Tesla was totally unresponsive. I am truly scared to drive the car again, even if it gets repaired. The car only has around 20k+ miles. This should never have happened, and Tesla failed to give me a warning before the major malfunction occurred. Truthfully, I do not know if I will ever drive my Tesla again. I no longer trust the vehicle.

the PTC heater fails on a lot of the older cars leaving them stranded. The % of cars effected is alarming. This should be recalled to prevent people from being stranded in the cold.

2019 TESLA MODEL 3. CONSUMER WRITES IN REGARD TO TRUNK HARNESS SAFETY RECALL. THE CONSUMER REQUESTED INFORMATION REGARDING WHEN THE HARNESS MAY BE AVAILABLE.

I'm submitting this because my safety recall NHTSA # 21V-00D which was sent to me on Feb 15, 2022 has not been serviced in a timely manner by Tesla. The letter I got stated that they would either replace the harness, or install a guide protector for the rearview camera. However they have done neither. When I call them about it, they tell me "everything is fine, there are no repairs available for your car, just keep using it as normal". When I told them that what they were telling me disagreed with the recall notice, they told me to "ignore the recall notice".

Tesla provided notification of NHTSA Recall No. 21V-00D regarding the coaxial cable affecting camera visibility on 12/31/21. There is no estimate of when they will replace this cable, just that they have no parts available. I believe a reasonable time has passed and would like to have this safety issue resolved.

NHTSA Recall No: 21V-00D My vehicle has been affected and suffering from the defect noted by the NHTSA. For approximately five months I have unsuccessfully attempted to have the defective condition repaired to no avail. Most recently the vehicle was taken to a Tesla Service Center to have to recall performed, however upon arrival I was informed that the parts were not available and the service center informed me incorrectly that the the parts were available. Specifically, the service center advised they did not have a grommet to complete the repair and would not repair the vehicle without the grommet. I was informed that although the service center had the rear camera coaxial cable in stock, which would have repaired the defect the service center would not perform the repair without the rubber grommet as well. Upon being informed the repair would not be completed as previously promised, I requested the alternative repair be performed for safety reasons to prevent the intermittent problem becoming permeant. I requested the "guide protector" be installed as a temporary solution to the rear camera ceasing to function for days at a time after I open and close the trunk. The alternative repair is described at: https://www.tesla.com/support/model-3-trunk-lid-harness-retrofit "How will Tesla repair my car and how long will it take? At no cost to you, Tesla Service will inspect the trunk harness on affected vehicles for wear. If the amount of wear is within the specification for the coaxial cable, Tesla Service will install a guide protector to prevent further wear. If the amount of wear is beyond the specification, Tesla Service will replace the harness and install a guide protector." I have submitted numerous photographs to the Tesla documenting the recalled defective condition that creates an enormous safety hazard. To date the only solution I have is to not use the trunk whenever the camera is actually working.

No timely remedy provided for recall 21V-00D. The recall was initiated in December, six months later the manufacturer has no resolution.

The contact owned a 2019 Tesla Model 3. The contact stated that while driving at 57 MPH during rainy weather conditions, when hitting a puddle the vehicle then drastically slowed down and fishtailed veering to the left. As a result, the contact crashed into the divider. The air bags deployed. A police report was filed. The vehicle was towed to a AAA center where it was confirmed a total loss. The contact mentioned that the failure could be related to Phantom Braking. The manufacturer was not informed of the failure. The failure mileage was 27,140. It was determined that there was no phantom braking at the time of the accident. Consumer stated he would like to withdraw the complaint.

THE ONLY DISPLAY IN THE CAR WILL TURN OFF WHILE DRIVING. THIS CAUSES A LOSS OF ALL READOUT. YOU LOSE THE SPEED YOU ARE TRAVELING, HVAC, BACKUP CAMERA, SAFETY WARNINGS, ETC. THIS HAS HAPPENED OVER AND OVER. THIS HAS BEEN REPORTED TO TESLA AND THEY DECLINED TO FIX IT UNDER WARRANTY WHEN FIRST REPORTED AT APPROX 1500 MILES. THIS IS NOT A ROAD LEGAL CAR WHEN THE ONLY DISPLAY INTERMITTENTLY STOPS WORKING FOR AN UNDETERMINED AMOUNT OF TIME WHILE IN USE. *TR

THE ONLY DISPLAY IN THE CAR LOCKED UP, TURNED OFF, AND TURNED BACK ON APPROXIMATELY A MINUTE LATER WHILE I WAS BACKING UP WHICH CAUSED LOSS OF ALL READOUT INCLUDING THE BACK UP CAMERA, MPH, ACCESS TO MANY OTHER VEHICLE FEATURES. I REPORTED THIS TO THEIR SERVICE GROUP WITH A DATE/TIME STAMP FOR THEM TO IDENTIFY AND REPAIR THE PROBLEM BUT WAS TOLD THAT THEY WOULD NOT LOOK AT THIS UNDER WARRANTY BUT THEY COULD PROVIDE AN ESTIMATE TO HAVE THE PROBLEM CORRECTED AT MY EXPENSE. THIS IS A SAFETY ISSUE AND SHOULD BE COVERED UNDER THE NEW CAR'S WARRANTY. THE ONE AND ONLY DISPLAY SHOULD NEVER LOCK UP WHILE THE VEHICLE IS MOVING BUT IF IT DOES, SERVICE SHOULD TAKE ALL REPORTS OF THIS OCCURRING VERY SERIOUSLY.

THE BACK UP CAMERA VIDEO FEED HAS PURPLE AND GREEN VERTICAL LINES THAT GOES THROUGH IT INTERMITTENTLY LIKE THERE IS A SHORT. THE ISSUE WAS REPORTED TO SERVICE VIA EMAIL WITH A PICTURE FOR THEM TO BE ABLE TO IDENTIFY AND REPAIR THE PROBLEM AT A FUTURE SERVICE APPOINTMENT. I WAS THEN TOLD VIA TXT THAT THIS WAS NOT A WARRANTY ISSUE AND THEY COULD ONLY PROVIDE AN ESTIMATE TO HAVE THE PROBLEM CORRECTED AT MY EXPENSE. HAVING A FAULTY BACKUP CAMERA FEED IS DEFINITELY A SAFETY CONCERN WHEN YOU ARE TRYING TO USE IT TO BACK UP. THEY SHOULD TAKE THESE REPORTS SERIOUSLY AND NOT DISMISS THEM.
