As we were normally driving, the car lost power immediately with no warning sign. After the power is lost, brake does not function, electrical door button doesn't function, hazard light doesn't function. Car was able to scroll to a complete stop to the side of the road. The steering wheel is locked. Again, BRAKE DID NOT FUNCTION after the power is lost. No button works, no screen turns on, car is not able to turn to neutral. There was no collision prior and no warning prior. Tried to file a police report. But Officer [XXX], badge # XXX, refused due to there was no collision and no accident.

NHTSA complaint #11763172 — an unverified report by a vehicle owner.
While my wife was driving, the high-voltage battery failed and the car went into reduced power/limp mode. Tesla later determined that coolant had gotten into the high-voltage battery and caused it to fail. My main concern is that we had no warning that there was a coolant leak or that coolant was getting into the battery. There was no low-coolant warning or anything telling my wife that there was a serious problem developing. By the time the car started giving high-voltage and reduced-power warnings, the damage had already occurred and Tesla said the battery needed to be replaced. What concerns me even more was what happened after Tesla received the car. Tesla removed the battery and quarantined it in the parking lot. They told us in writing that it was removed because of coolant ingress as a safety precaution and that a specialized technician had to determine whether the battery was safe to discharge. During a phone call, a Tesla employee also told me they quarantined it because there was a possibility the battery could explode and they did not want anyone injured or anything damaged if that happened. That was alarming because my wife had just been driving this car, and afterward it sat in our driveway while we waited for it to be taken to Tesla. At no point were we told that the battery could be dangerous or that the vehicle should be kept away from people or property. We had no idea Tesla would consider the condition serious enough to quarantine the battery once they received it. Tesla later confirmed in writing that coolant ingress was the root cause of the battery failure. I would like NHTSA to look into why this condition was able to get this far without warning the driver and whether other vehicles could have the same issue.
NHTSA complaint #11762441 — an unverified report by a vehicle owner.
Client left the road and the vehicle hit a tree by the roadside. The vehicle caught fire and client was incapacitated and unable to operate the door handle from the inside or unlock the doors. Bystanders attempted to open all four doors from the outside, but they were all locked. Bystanders noted that the handles themselves were functional and believe it was an electrical issue keeping the doors locked. Bystanders broke the windows and attempted to open the doors from the inside, but they were unable to access the emergency door release because the driver door panel was on fire in proximity to the emergency release. Bystanders began mechanically disassembling the door to get him out and he was eventually extracted by the fire rescue team. The inability to open the door delayed our client being extricated from the vehicle and as a result he suffered severe injuries, including the loss of both legs, due to severe burns. The vehicle is currently being held by Copart Miami South and is available for inspection. So far, it has been inspected by the insurance company and our experts. Warning lamps, symptoms, etc.: UNKNOWN. Vehicle is badly damaged, so we are not able to recreate/confirm the problem at this time.
NHTSA complaint #11761374 — an unverified report by a vehicle owner.
My 2022 Tesla Model 3 Long Range has developed a failure of the Autopilot/ADAS computer. The AP computer remains installed in the vehicle and is available for inspection. The vehicle operated normally before software update 2026.26.6. Following the update, Driving Visualization and Autopilot began going offline, along with automatic headlights, automatic turn signals, emergency braking, collision and traffic warnings. The failures have continued despite software/firmware reinstall, DAS reset, camera calibration, and hard reset. Tesla Service inspected the vehicle and confirmed that the AP computer is defective and recommended replacement at approximately $2,600. I paid $120 for Tesla's diagnostic assessment. Service Mode has recorded repeated AP watchdog/kernel-panic events, including APS_w169_TurboA_SCS_LKUP, APS_w134_appMIA, APS_w135_appCritical, and PM_a041_dasMIA. The vehicle has also recorded simultaneous exits of multiple camera streams, sometimes causing camera feeds to go black while driving. Service Mode has shown the AP ECU in Coreboot/INIT, intermittent loss of communication between the AP ECU and infotainment ECU, missing GNSS Ethernet communication, and unavailable AP temperature telemetry. This creates a safety concern because multiple safety-related driver-assistance and camera-dependent systems can unexpectedly become unavailable while driving. The vehicle remains manually drivable, but the driver must unexpectedly operate without previously available functions. The failure can also affect automatic headlights and turn signals, requiring manual operation. I am reporting this as a potential safety defect because multiple ADAS/camera systems fail simultaneously and the AP computer repeatedly crashes/reboots. The failure began after a software update, although Tesla has stated that some alerts predated the update. Due to the GPS board contacting the autopilot first before the infotainment, precise location is off and navigation is unavailable.

NHTSA complaint #11757430 — an unverified report by a vehicle owner.
Tesla’s replacement of physical steering column turn signal stalks with capacitive touch buttons on the steering wheel face creates an active safety hazard. First, the capacitive sensors frequently become entirely unresponsive. If a driver rests a finger near the buttons, the system triggers a timeout/lockout, rendering the signals non-functional for several seconds when pressed. They also fail to register inputs under normal pressure or when wearing gloves. Second, because the buttons rotate dynamically with the steering wheel, it is structurally impossible to signal by muscle memory during sharp or sequential maneuvers, like navigating roundabouts. To signal while the wheel is turning or when buttons fail to respond, the driver must repeatedly look away from the road to visually target the wheel. This defective layout causes delayed signaling, severe driver distraction, and elevates the risk of a collision.

I was operating my Tesla with Full Self-Driving (FSD) engaged when the incident occurred. I was turning right onto [XXX] from [XXX] and was positioned in the left right-turn lane approaching a railroad crossing. The railroad crossing gates were already fully lowered, indicating an approaching train. Despite the lowered crossing gates, the vehicle accelerated forward into the crossing rather than stopping. The vehicle drove through the lowered crossing gate, which struck and shattered the windshield. Seconds later, the train passed through the intersection. I did not command the vehicle to proceed through the lowered gates. The incident resulted in significant damage to the windshield and raised serious safety concerns because the vehicle entered an active railroad crossing immediately before the train arrived. The vehicle was towed to a Tesla Service Center due to the damage. Fortunately, no collision with the train occurred and there were no injuries, but the incident had the potential to result in catastrophic injury or death.

NHTSA complaint #11755168 — an unverified report by a vehicle owner.
I own a 2022 Tesla Model 3 that is just past the 5-year/60,000-mile warranty. I bought it used from Tesla inventory and picked up my vehicle on June 1st, 2026 with ~32,000 miles on the odometer. The front passenger safety restraint system alert (RCM2_a636) first appeared on June 5, 2026. On June 15 at 64,008 miles, Tesla Service confirmed the airbag alert and front passenger OCS issue. They found the occupant classification system module damaged and exposed, replaced it, and noted the passenger-side module shorting was also causing a driver-side error. Both cleared after the repair and test drive. Cost: $363.23. The same alert came back. On July 30 at 66,475 miles they found an open in the passenger seat cushion self-capacitance trace wire and the driver occupancy sensor voltage out of range. They replaced the front passenger seat cushion trim and the driver seat occupancy sensor. Alerts cleared and the self-driving button now worked from park again which never did prior showing the issue was never fixed the first time. Cost: $930.36. No crash or injury, but this is a real safety risk. The restraint system may not work as designed and airbags could fail to deploy properly. This exact RCM2_a636/OCS fault keeps happening to other Model 3 owners both before and after warranty on forums, and Tesla has service bulletins on the same parts, yet people still end up paying for the repairs who are out of warranty and also have their safety and life at risk. Please investigate this as this is a severe safety defect.

The Front Passenger Safety Restraint System failed prematurely on my 2019 Tesla Model 3 at only 23,105 miles, triggering the alert 'Alerts - Seats - Front passenger safety restraint system issue/Service is required' and disabling passenger airbag functionality. Upon inspection, Tesla Service quoted $1,285.13 out-of-pocket to repair the system. While the root failure involves a $12 occupant occupancy sensor (Part #1099592-00-F), Tesla's mandatory service procedures require a full subsystem revision cascade to fix it. Specifically, under 'Replace Occupant Classification System (OCS) of Front Passenger Seat while Servicing Subcomponents' and 'Update Front Passenger Airbag to Maintain Compatibility with Front Passenger Seat,' Tesla requires replacing the right-hand seat harness assembly (Part #1489060-03-G) and the complete Front Passenger Airbag (Part #1077823-00-G) solely to maintain hardware compatibility with the revised sensor. Because Tesla redesigned subcomponent hardware without offering a backwards-compatible replacement sensor for earlier Model 3 production units, restoring a critical primary safety system creates an exorbitant financial barrier, forcing the vehicle to be operated with disabled airbags.
NHTSA complaint #11753364 — an unverified report by a vehicle owner.
Component/system: The front passenger Occupant Classification System (OCS) in my 2018 Tesla Model 3. The vehicle is available for inspection on request. Description of the failure: The vehicle intermittently displays "Front passenger safety restraint system fault — service required]" on the center touchscreen. The alert first appeared on or about 4 years ago and has recurred approximately ~50 times since. The failure is strongly correlated with cabin temperature. It appears after the vehicle has been parked in direct sun in warm weather, and clears on its own once the cabin cools. It has not occurred in cooler ambient conditions. Safety risk: On this vehicle the front passenger seat uses a capacitive Occupant Classification System rather than a simple occupant-detection pad. The restraint control module uses OCS output to determine both whether the passenger airbag deploys and at what force. When the system faults, I have no way to know whether the passenger airbag is suppressed, will deploy at an inappropriate force for the occupant, or will deploy at all. This directly compromises frontal crash protection for anyone in that seat. I have been avoiding seating passengers there as a result. Inspection and confirmation: The vehicle is outside the basic warranty. Per Tesla's own service documentation, the passenger-side OCS sensor is not individually serviceable; the remedy requires replacing the seat cushion assembly and running a proprietary calibration routine that requires a cabin temperature near 68°F. The vehicle has not been inspected by police, insurance, or any independent shop. Prior warning symptoms: The touchscreen alert described above is the only symptom. There was no prior indication. There is no open recall for this condition on my VIN. Given the number of similar owner reports and the cost of the remedy, I believe many affected vehicles remain unrepaired and in service.

I was locked inside my tesla model 3 two stories down in a parking garage with no internet access to find out where the emergency release was for my door. I KICKED my driver side window to survive. It wasn't until after I was told that the doors are tied to a 12v battery that had died without warning. I did not know the doors tied to that nor that there was a secret emergency release. There are no clear indicators within the car that this is how it operates and you SHOULDN'T NEED INTERNET ACCESS AND ELECTRICITY TO SURVIVE EXITING A CAR.

While out on vacation in [XXX] on XXX at around 11 am I had just finished charging the Tesla at a supercharging station. I was headed to go eat breakfast at the intersection of [XXX] and XXX on the right lane. I stopped briefly prior to making a right onto [XXX]. Upon making the right turn the vehicle kept turning all the way right and making a sharp right turn instead of a soft right. When I noticed the sharp right turn I tried to turn the steering wheel towards the left but the steering wheel was locked and it wouldn't respond. The car drove me into a concrete barricade and caused a collision. My children were in the car and thankfully no one in my vehicle was seriously injured nor were there any pedestrians on the sidewalk near the barricade. I contacted Tesla for the repair and investigation into why the steering wheel locked. Tesla has not provided a loaner vehicle in the meantime despite my frequent requests. This incident is a serious and critical safety issue that may have caused deaths had I been traveling at a higher rate of speed or been on the highway heading back to [XXX]. The strange thing is that this vehicle is still under warranty with Tesla and had been working just fine without any issues since I got the vehicle in XXX. No warning messages, or symptoms to indicate any malfunction. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
NHTSA complaint #11751359 — an unverified report by a vehicle owner.
The high voltage battery on my 2021 Tesla Model 3 Standard Range suddenly failed without any prior warning or gradual degradation. The vehicle was consistently achieving approximately 180 miles of range per full charge. Overnight, the battery charge was restricted to approximately 30% capacity, reducing usable range to roughly 30 miles. No warning signs or symptoms appeared prior to this failure. The failure was sudden and immediate. The vehicle displayed the alert "Maximum Battery Charge Level Reduced / OK to Drive, Schedule Service." The battery has been confirmed by a Tesla Service Center as having an internal fault. The only remedy offered by Tesla is full battery replacement at a cost of approximately $9,000 to $14,000 depending on the option selected. This failure poses a safety risk as the severely limited range can result in the vehicle becoming stranded unexpectedly, particularly during highway driving or in areas without nearby charging infrastructure. The failure occurred approximately 6 months after the battery warranty expired with no prior indication of degradation, suggesting a potential defect in the battery unit. The vehicle has been inspected by a Tesla Service Center and the fault has been confirmed. The component is available for inspection upon request.
NHTSA complaint #11750373 — an unverified report by a vehicle owner.
Vehicle displayed a “Safety Restraint System Issue - Service Required” alert (fault codes RCM_a056 and RCM_a032). Tesla diagnosed an open circuit between the driver-side curtain airbag and the left airbag controller, requiring replacement of the left body harness. Tesla quoted approximately $1,800–$2,200 for the out-of-warranty repair. This is a known, recurring pattern — multiple other 2018 Tesla Model 3 owners report experiencing this identical fault at nearly the same mileage (~78,000 miles), suggesting a design or component wear issue rather than isolated damage, similar to a prior Tesla trunk-harness recall (NHTSA campaign 21V-00D) that also stemmed from a wiring/harness defect on this same vehicle. I am requesting NHTSA investigate whether this represents a safety-defect trend warranting a recall.

Complaint Title: Defective Horn System on 2026 Tesla Model 3 - Ineffective in Rain or Highway Conditions Description: The horn on my 2026 Tesla Model 3 Highland is dangerously inadequate. It uses a single pedestrian warning speaker instead of a proper horn, which is easily overpowered by road noise, tire noise from large trucks, and especially rain. I cannot reliably alert other drivers, including 18-wheelers, when they are drifting into my lane or failing to yield. This creates a serious safety risk in wet conditions and highway driving. Traditional horns have been effective for decades — this design fails basic safety expectations. I am requesting immediate investigation and a fix.
