2025 Tesla Model 3 Engine Problems

After the High Voltage Battery Contactor recall service, my 2025 Tesla Model 3 Performance suffered a sudden 13% drop in range (from 303mi to 264mi at 100% charge). An official Tesla Battery Health Test confirms the battery health is at 92% in less than a year of ownership. This degradation happened immediately following the recall procedure, indicating a hardware or software defect caused by the service.

On [XXX], at just 9,526 miles, my brand-new 2025 Tesla Model 3 (VIN: [XXX] ) suffered a front motor/inverter failure. The vehicle displayed the warning “Front Motor Disabled.” Tesla Vallejo Service confirmed this and replaced the front drive inverter (3DU). A catastrophic drivetrain failure at under 10,000 miles is unacceptable and raises serious concerns about reliability and safety. It still doesn't not accelerate as before. In addition, since delivery on [XXX], this vehicle has had persistent rattling and vibration issues in the cabin. I have returned to Tesla Vallejo multiple times (April, June, July, and August 2025). Each time, the service manager, Steve McNerney, dismissed or minimized my concerns, blaming “seatbelt rattling” or claiming the issue could not be replicated. After July, I even sent three separate videos clearly documenting the noise, yet the most recent service invoice still instructed me to “provide a video,” showing Tesla ignored or failed to record my evidence. This ongoing defect has been reproduced and confirmed at Tesla service but remains unresolved. Tesla’s dismissive handling and failure to fix the defects create both safety risks and loss of confidence in the vehicle. A front motor failure while driving could result in loss of power, reduced acceleration, or unsafe driving conditions. Tesla has failed to provide a reliable or safe resolution despite repeated repair attempts and clear evidence.
