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 center touchscreen/camera display system in my 2021 Tesla Model 3 is malfunctioning. The vehicle’s camera views do not work properly on the center display, including camera visibility needed for reversing and safe operation. The failed system is available for inspection upon request. This creates a safety risk because the vehicle relies heavily on the center screen to display camera views and vehicle information. When the camera display does not work properly, rear and surrounding visibility is reduced, especially while reversing, parking, changing lanes, or maneuvering around pedestrians, vehicles, curbs, and other obstacles. Tesla has refused to repair or cover the repair. The problem has been reported to Tesla. Tesla has not provided a satisfactory safety-related repair solution. It is unknown whether Tesla has fully inspected the failed component or confirmed the exact cause. There were no known warning lamps before the failure. The symptom is that the camera display/center screen camera views do not function properly when needed. The issue appears to involve the center display, camera display system, camera hardware, wiring/harness, vehicle computer, or related software. The exact cause is unknown. I am reporting this as a potential safety defect involving loss or malfunction of the camera display system in a 2021 Tesla Model 3.

The contact owns a 2022 Tesla Model 3. The contact stated that while operating the vehicle, abnormal crackling and bubbling sounds were heard coming from underneath the rear seat. While driving later, an electrical arcing sound emanated from the same area. While at a local charging station, the contact discovered that the battery failed to charge when connected to a high-voltage charger; however, the battery could still be charged at the contact's residence using a 110-volt charger. The vehicle was driven to a local dealer, who was unable to identify the problem, and no service was performed. The vehicle was driven back to the charging station, but the high-voltage charging failure persisted. The vehicle was then towed to a local service center, where it was diagnosed and it was determined that the high-voltage battery required replacement. The high-voltage battery was replaced, and the vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was 38,200.

While driving my Tesla, Autopilot was engaged and navigating with the destination entered. At the time of the incident, my hand was on the steering wheel when the vehicle suddenly attempted to make a hard right turn toward a divider. This was not an exit or intended route, which raises serious concerns about what caused the vehicle to react that way. In addition, I have experienced multiple battery-related issues with this vehicle. The battery has already been replaced once, and on approximately 2–3 occasions the vehicle entered “Turtle Mode,” limiting the car to about 35–50 mph. This created a serious safety hazard because it occurred while I was driving on the highway alongside tractor-trailers and fast-moving traffic.

My 2022 Tesla Model 3 experienced a heat pump compressor failure at approximately 89,457 miles. Tesla Service Center diagnosed an internal failure in the heat pump system. The heat pump system controls cabin heating, windshield defrosting, and thermal management for the vehicle. When the system failed, the vehicle lost heating and proper defrost capability. This can impair windshield visibility during cold or foggy conditions, creating a potential safety hazard while driving. Tesla quoted approximately $3,000 to repair the compressor and declined warranty assistance despite the system being critical to safe vehicle operation.

RECURRING 12V LOW-VOLTAGE SYSTEM FAILURE AND DEFECTIVE REAR DEFROSTER HEATER GRID VEHICLE: 2022 Tesla Model 3 (VIN: [XXX] ). ODOMETER: 114,093 miles at time of third service visit. SUMMARY OF DEFECT: Vehicle has experienced recurring low-voltage (12V) system alerts since late December 2025. The 12V battery has been replaced three times by Tesla service. After each replacement, the low-voltage alerts return within days. Tesla's diagnostic system detected a DCR (DC resistance) reading of 16.8 milliohms against a threshold of 16 milliohms, indicating the battery's internal resistance is too high for the vehicle's electrical system to function properly. A brand-new 12V battery showed "Degraded - Replace" status within one week of installation. These low-voltage errors did not exist before Tesla replaced the 12V battery during the first service visit. DIAGNOSTIC FINDINGS: During the third service visit (February 2026), Tesla technician performed a resistance check on the rear defroster heater grid and described it as "out of spec but not significantly." Ground straps were also described as "out of spec but again not significantly." The technician stated there was "no smoking gun yet" and it was "maybe a combination of all leading to the 12V warning." Tesla proposed replacing the rear backlight glass at a cost of $1,265 to the customer. Additionally, severe rodent damage was discovered in the front wiring harness with chewed wires and nesting material. Despite this confirmed damage to the electrical system, the service manager stated the rodent damage was "not associated with the error" while the technician simultaneously stated there was no confirmed root cause. SAFETY CONCERN: The recurring 12V low-voltage condition presents a safety risk. The 12V system powers critical vehicle functions including exterior lighting, hazard lights, door locks, windows, the vehicle's computer systems, and safety features. Repeated system alerts include DIF_a018_hwLVSupplyUV (ha INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATIO

When cabin heat is enabled, visible vapor/smoke emits from the front trunk area under the windshield cowl and is pulled directly into the cabin through the HVAC intake. The vapor has a chemical/sweet odor consistent with coolant or refrigerant. Smoke enters the passenger compartment, especially when stopped or idling. This occurs repeatedly in cold temperatures and stops immediately when HVAC heat is turned off. No warning lights appear. This appears to be a heat pump or coolant system leak upstream of the cabin intake, allowing chemical fumes to enter the cabin air stream. Occupants are exposed to fumes while driving. This is a safety concern due to inhalation risk and lack of driver warning.

Submitted Under 49 CFR §552.3 Request for Defect Investigation & Safety Recall Tesla Model 3 / Model Y: Interior High-Voltage Heater Fire Hazard, Missing Firewall, and Entrapment Due to Electronic Door Failures. My 2022 Tesla Model 3 experienced an interior flash fire caused by a design defect. Tesla placed the high-voltage PTC cabin heater and HV wiring inside the dashboard with no firewall. After a crash, I saw a straight “strip flame” shoot out of the HVAC dash vent, exactly like a gas heater. The fire began INSIDE the dash/HVAC ducting within seconds of impact, not from the battery. This shows an arc-flash failure of the HV heater or wiring inside the cabin. The flame entered the cabin instantly because there is no firewall separating HV components from occupants. During the fire, all electronic door releases failed. Tesla hides the manual front releases and provides NO rear mechanical releases. I was trapped inside a burning cabin and suffered major injuries trying to escape by kicking the rear passenger window before bystander helped me brake out the rear passenger window to get me out. Most people cannot escape this design. This is a dangerous combination of defects: (1) HV heater and wiring located inside the cabin with no firewall; (2) HVAC ducting becomes a flame pathway; (3) Electronic door releases fail during fire/crash; (4) No labeled manual rear-door exits; (5) No backup 12-V actuator power to open doors. Tesla must: relocate the HV heater outside the cabin (frunk), add a real firewall, add fire-retardant HVAC materials, add labeled manual releases on all doors, and include a 12-V backup to door actuators. Please open a defect investigation. This design nearly killed me and will kill others.

All safety and driver-assistance systems on my 2022 Tesla Model 3 failed due to an internal short in the vehicle’s computer, as confirmed in writing by Tesla’s technician. All cameras (rear, side, front) are non-functional, navigation does not work, and all ADAS features (Autopilot, lane-keeping, collision warning, blind-spot monitoring, emergency braking, etc.) are disabled. The vehicle has no visibility when reversing and no active safety protections while driving. Tesla documented the cause as an internal computer failure, not related to damage or misuse. This creates a dangerous condition on public roads since the car loses all safety systems. Tesla quoted ~$2,900 for a new computer even though the failure involves critical safety components. This may indicate a broader safety defect.

During a head-on collision on [XXX] in Georgia, the electrical system in my 2022 Tesla Model 3 lost power and the electric door releases stopped functioning. The vehicle interior caught fire and I was trapped inside. I was unaware of the location of the hidden mechanical emergency door release because it is not visibly labeled, not explained upon delivery, and not intuitive in an emergency. I was forced to climb to the back seat and break the rear passenger window with my legs to escape while the interior was burning. I suffered a broken hip, broken arm, and later required a full hip replacement. The mechanical emergency door release was concealed and unlabeled, resulting in entrapment during a fire, which is a violation of FMVSS 206 and presents a continuing and life-threatening safety hazard to all drivers and passengers. Tesla has not provided warnings, recall guidance, labeling, or owner education regarding how to exit the vehicle during a power-loss emergency. This defect can result in deaths. I am requesting a formal investigation. DP25002 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Shortly after purchasing my 2022 Tesla Model 3 RWD in February 2025, I began noticing a persistent musty, mold-like odor coming from the HVAC vents whenever the air conditioning or defrost was on. The odor worsens when driving with the windows down. I reported this issue to Tesla multiple times between May and October 2025. Tesla replaced the cabin filters but refused to perform a full evaporator or HVAC disinfection, stating the odor was “normal.” Despite the filter changes, the smell always returns within a few weeks. Between these visits, I also tried to resolve the issue myself by replacing filters, using odor-eliminating products, and placing moisture absorbers inside the vehicle, but nothing has resolved the problem. This ongoing issue has led to repeated respiratory and eye irritation, including a documented pneumonia case in April 2025. The symptoms clearly worsen after time spent in the car. Tesla has not offered any permanent fix, warranty repair, or replacement. The problem appears to stem from mold or microbial buildup within the HVAC evaporator and duct system, which could affect air quality and occupant health. This raises safety concerns regarding possible HVAC design flaws or moisture retention issues that may affect other Tesla vehicles. The issue is ongoing as of November 2025 and has been reported to the Florida Department of Agriculture and Consumer Services (FDACS Case #2511-00831) for further review.

Tesla M3 RWD 2022 - 79750k miles. Touchscreen keep restarting throughout the day , in the morning when I am backing out of the garage, while I am driving, while I parked. It is dangerous specially while I am backing out of garage, car will stop sometime, because whole system reboots. I have no visibility I have to wait till its finish restarting. Tesla's main computer handles everything in the car, A/C, Turn signals, speedometer, backup cameras, forward collision warning and many more necessary function of the car. Tesla service center diagnose stats "The cause was identified as kernel panics detected in the system. The internal memory of the car computer is corrupt and will not allow enough data transfer and causing the computer to reboot to clear space" They suggested to replace the computer and its a out of warranty fix, since I drove 79k miles. This is a crucial of the car and it should not fail in 3 years, driving 79k in California is not unusual, Tesla service also blamed that we didn't extended our warranty after 50k. We couldn't find any correspondence from Tesla on service app or email regrading warranty extension. $3000 to replace a computer is a very high price.

Our car was parked in our garage for two days before August 25, 2024 not plugged in for charging and was clear of issues. On the morning of August 25, 2024 we woke up to the smell of smoke and evacuated our house as the source was coming from our Tesla in the garage. This incident burned our home and took 6 of our cats with it. We filed with insurance and they are reporting that they are not liable for the accident. They did not bother to show up to the joint investigation and paid the bare minimum for the market price of the vehicle. The company has been slow in responding and has shown zero remorse or care of the matter. Fire department pinned it as a 99.9% probability of cause that the front battery of the Tesla triggered the fire.

I was driving on the highway when the touchscreen lit up with multiple error messages including: - Steering assist reduced (Steering may require increased effort) - Traction control disabled (Drive with caution) - Stability control disabled (Drive with caution) - Parking brake functions degraded (Parking brake may not apply or release) - Lane Departure Avoidance features unavailable (Features may be restored on next drive) Also, the speedometer changed to 0 (while we were going 70 mph). When I pulled onto the next off-ramp the steering was very heavy and the regenerative braking was not working. Pressing the brakes (even slightly) felt like the ABS was pulsating. This was extremely dangerous and easily could have resulted in a serious accident in heavy traffic or if the road had not been straight. It was a rental car so I have not seen the car since the rental company towed it away. I have not heard from the rental company about the car's status or their findings. Prior to the catastrophic failure of multiple systems, there were two other warnings messages: - Left front fender camera blocked or blinded (Clean cameras or wait to regain visibility) - Autopilot safety/convenience features unavailable (Features may be restored on next drive) These had been coming on and off for a couple hours but I had assumed they were due to driving through heavy rain.

The following will happen in drive or reverse. Causing the vehicle to enter a free roll condition. If the vehicle detects both pedals are pressed. The vehicle will then disengage the motors and the brakes. And it will free roll. The vehicle does not successfully maintain stop and hold in this case. I was stopped at a red light and on an uphill. When the light turned green, I bumped the brake pedal when I went to accelerate forward in drive. My car rolled backwards downhill as a result. My instinct was to press the accelerator to try and go forward before I thought to hit the brake. My car rolled about 1.5 car lengths backwards. Luckily nobody was behind me. This is a safety issue that has existed for the 3 years that I have owned this car. Not once has this been corrected in a software update. This is a serious safety problem and I’m surprised nobody has free rolled into a pedestrian or vehicle because of it. Or if they have, maybe they don’t know that it was caused due to this vehicle behavior. The software needs fixed to prevent free rolling in drive or reverse. Normal gas cars don’t suddenly fall to neutral and free roll all over the place if you bump both pedals. like wow.
