What 591 owners told NHTSA about the 2019 Tesla Model 3

The contact owns a 2019 Tesla Model 3. The contact stated that while the rear seat warmer was active, a hole had burned through the seat due to the heat coming from the seat warmer. The contact stated that a blanket was placed over the seat which caused the blanket to melt and fuse into the seat. As a result of the failure, the contact had to tear apart the back of the seat where the failure occurred. The contact spoke to a Tesla service technician who gave the contact an estimate for the repair. The vehicle was not repaired. The failure mileage was approximately 78,000.

My vehicle has developed a rapidly worsening battery performance issue. It loses range far faster than expected, shows inconsistent energy usage, and experiences sudden drops in projected mileage even during normal driving. Charging behavior is irregular, and the vehicle’s energy regeneration is inconsistent. There was no crash, fire, or damage. Based on the symptoms, this appears to be a potential battery or propulsion system defect. The issue continues to worsen and affects the safe and reliable operation of the vehicle.

Tesla remotely disabled Supercharging access on my vehicle without any warning, safety errors, or mechanical problems. The vehicle charged normally for months, including recent Supercharging sessions, and still operates safely. Tesla stated Supercharging was disabled due to a “salvage” title and now demands a $1,900-$2,400 “inspection” to restore access, with no diagnostic evidence of any issue. This appears to be a remote software lockout of a critical charging feature without a safety justification. It limits safe operation and access to public charging infrastructure. I request NHTSA investigate this policy as an unfair and potentially unsafe manufacturer action.

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.

There is an error with my car's Occupant Classification System (OCS) which is giving me an alarm of "Front Passenger Safety Restraint System Fault". Tesla only "fix" is to replace the OCS with what seems to be a newer version. You can tell it is a new version because they are also telling me I need to replace my airbag as my current airbag is not compatible with the new OCS.

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.

My vehicle displays a persistent warning: “Front Left Safety Restraint System Fault.” A technician told me this fault relates to the driver seat sensor and is the same defect addressed by a previous NHTSA recall. However, I’ve confirmed that my VIN was not included in that recall. Despite the recall fix being implemented for some vehicles, my car still has this safety restraint fault with no resolution offered. This ongoing problem concerns me because it affects the proper functioning of the vehicle’s safety system, and I fear that my vehicle’s defect remains unaddressed. I request that NHTSA investigate this issue, as it appears the recall did not cover all affected vehicles and that Tesla’s recall scope may be insufficient.

passenger safety restraint system light came on, Tesla says to fix needs to install OCS filter module and replace existing OCS sensor because its not compatible with existing OCS sensor...cost is $806....there are no broken parts in my car. according to Teslas service bulletin Sep 21, 2020 this problem is caused by electrical interference in the seat harness causing the airbag restrain system message on screen due to faulty design.....Tesla says i need to pay for it because car is out of warranty, i say its a faulty design and they have to fix free. this should be a recall because Tesla is aware of many of same problems that make the airbag inoperable. from the bulletin "On some Model 3 and Model Y vehicles, the Occupant Classification System (OCS) signal might be affected by electrical interference in the seat harness, causing the airbag indicator to display on the touchscreen." Tesla has been aware of the problem for 4 years at least.

The airbag and seat belt system on the driver's side is faulty, which may result in an unsuccessful deployment of the airbag should I get into an accident. This is an immediate safety concern, yet Tesla would like to charge me over $400 to remedy the situation. That's why I'm reporting this as a safety recall so that no other owner/ leasee faces this risk or financial burden.

I’m at the Tesla service center and Tesla is refusing to perform recall work without payment/diagnostic time. Even though Tesla’s website and notices states that they will perform recall work free of charge they are in fact refusing to perform recall work free of charge. They are mandating that I be charged diagnostic fees for them to determine whether they will perform the recall work as of 11/13 at 7:15am per Marc the service advisor at Tesla Service Center Kearny Mesa.

There is a common warning message on Tesla Model 3 and Y that states “Front Passenger Safety Restraint System Fault” I just received it on mine. Tesla service advised that the passenger airbag and safety system may not function in the event of a crash. I searched online and can see in forums that many people receive this warning. Tesla also confirmed that if someone receives this message while driving and then they get into an accident during that same drive, the airbag may not work. This is a HUGE safety issue, and Tesla should be held accountable.

Safety issue: Got a "Front Passenger Safety Restraint System Fault" (code RCM_a056) out of a sudden. Apparently, the passenger's occupied-seat sensor is not communicating with the system, leading to potential hazard in airbag deployment scenario. Upon reaching out to the Tesla Service Center, got a quote for $1600, which includes a replacement not only of the passenger's seat sensor, but there's also a need to replace the airbag - to maintain compatibility with the new sensor. Upon additional research, I've discovered that this is not merely wear and tear; some owners reported that this error appears on brand new cars. In short, Tesla is requiring customers to pay $1600 to cover a design failure that could result in a safety / injury. The company should be held liable to its errors, not customers.

Safety features on my car are currently unavailable. I called the dealership and was told it was due to a defected sensor in the back windshield. And I would have to pay to replace the entire windshield. Even tho the sensor is defective.

An error has displayed on the screen stating: "Front Passenger Safety Restraint System Fault RCM_a056 Service is Required" and reaching out to the local Tesla service center, I discovered the prescribed repair costs $1600. After searching online for other owner's experience with the error, I discovered that this is a common issue caused by a wire connection to the seat control model coming loose due to a poorly tensioned connector. Those other owners have reported that Tesla knows about this issue in their manufacturing and is refusing to fix the issue or issue a recall even though it is a safety issue.

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.

I was driving my Model 3 when this alert occurred: ALERTS DRIVABILITY - VEHICLE MAY NOT RESTART/SERVICE IS REQUIRED ADDITIONALLY THE SCREEN STATED PULL OVER THE VEHICLE IMMEDIATELY SAFELY. I was in the middle of the road driving so it became dangerous. I could not steer the vehicle and the brakes were barely working. I could not immediately stop because I was in the middle of traffic. I pulled right over as soon as I could and shut down the vehicle. I believe this is a defect. When I spoke to Tesla repair personnel I was told they know about this and it is happening when the Model 3 reaches 40K. How can they not address this - why would someone wait until someone is in a serious accident? I called to set up an appointment for this emergency and was told I cannot get an appointment for 1 month and I should not drive my car. When an electric vehicle just shuts down you cannot control the vehicle - this is very very dangerous.

The car has a feature which adjust the seats for easy entry and for a driver based on driver profile. This results in the drivers seat to automatically adjust per profile. It seems overtime this damages a cable or connection under the seat, resulting in a fault in the sensor which recognizes a driver being present in the seat in case of emergency, ie determines if it should deploy airbag. Right now our car is showing this error and it’s only present when the seat adjust for my partner who is a shorter driver. Tesla has stated previously that this would be around $250 to repair, could only do it in person at the repair center. Online I’ve seen reports of onsite techs making the repair in less that 5 minutes with no or minimal charge for a replacement sensor or cable.

Tesla Model 3 battery pack coolant connector design flaw. It is made by plastic and covered with very thin cheap plastic cover which can very easily create impact and break the battery pack connector when any small objects hit front wheels(both side) while driving that leads the following safety and hazard issues to driver and passengers. 1. When there is hit in the coolant connector while driving the coolant start leaking which put safety of car,driver,passengers and others in very high risk 2. When it happens the dashboard shows the car is running reduced power and not giving enough info to take immediate action 3. This issue can be easily reproducible just driving the car in freeway where the road has debris or due to work zone 4. This issue reported to Geico Insurance 5. There is no warning before it first appears 6. It leads to change the entire battery pack which cost ~ $20,000 7. Since this is very critical component it should be well protected which is not the case currently
