2022 TESLA MODEL 3 — Problems, Recalls & Safety Data

I am filing a safety complaint regarding water intrusion into the rear tail lamp assembly of my 3-year-old Tesla Model 3. The rear tail light has progressed from minor condensation to active water accumulation and visible pooling inside the sealed housing. This is not light fogging — there is standing moisture inside the assembly. The vehicle has not been involved in any collision and there is no visible external damage to the lamp. I have already been pulled over, and drivers behind me have indicated that the affected tail light is not clearly visible. Reduced rear illumination creates a serious safety risk, particularly at night or in poor weather conditions. A malfunctioning tail lamp increases the likelihood of a rear-end collision. Rear lighting is a federally regulated safety component. Water intrusion into a sealed LED lighting assembly creates risk of electrical malfunction, corrosion, and sudden loss of rear illumination. The vehicle is currently out of warranty due to mileage; however, it is only three years old. A sealed LED tail lamp is not a wear-and-tear item and should not fail due to normal mileage accumulation. This appears to be premature sealing failure. I contacted Tesla Service regarding this issue. Their written response stated that because the vehicle is out of warranty due to mileage, any repairs would be at my expense. They did not address the safety concern or the presence of internal water accumulation. There are numerous reports from other Model 3 owners describing similar tail lamp water intrusion issues. I am requesting that NHTSA review whether water intrusion into sealed rear lighting assemblies constitutes a safety defect and whether further investigation is warranted.

While I was making a left turn my steering wheel suddenly got stuck. A vehicle almost hit me.

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

Tesla Full Self-Driving (FSD) drove the vehicle onto a curb inadvertently, a few days after a software update. The incident caused a scratch to the wheel and a cut in the tire. Tesla has refused to cover the repair, stating that FSD requires driver attention. The issue is that the vehicle had never driven into a curb on a 90-degree turn before. I had my hands on the wheel and did not anticipate the software making an incorrect decision and striking the curb. Full Self-Driving was engaged at the time, and the software made an incorrect calculation that resulted in the impact. Tesla should replace the damaged tire and repair the wheel. I have the 1 min recording of the incident but could not upload the video due ot its size being more than 10 MB.

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.
