2024 Tesla Model Y electrical system problems

“Safety Critical Bug: While driving on surface streets, FSD indicated (via initiating a right turn signal) it was going to make a right turn into a parking lot that was not specified on its current navigation path. I disengaged FSD. After disengaging FSD, the turn signal software remained in an active right-turn state. Physical turn signal stalk inputs (both light taps and full pushes in either direction) failed to override or cancel the signal. Vehicle continued signaling a right turn, and the signal could not be manually cancelled. Only after about a minute of driving straight, did the signal self-cancel.”

“Subject: Formal Safety Complaint – Tesla FSD Failure and Missing Video Evidence Vehicle: 2024 Tesla Model Y Long Range VIN: [XXX] FSD Version: FSD (Supervised) v14.3.10 Incident Date: October 9, 2026 Location: [XXX] Dear NHTSA, I am filing a formal safety complaint regarding a suspected failure of Tesla's Full Self-Driving (FSD) system. On XXX, my wife activated FSD while our Tesla Model Y was parked in a parking lot. The vehicle began reversing and collided with another stationary vehicle behind it. Although the other vehicle showed no visible damage, our Tesla suffered significant deformation to its trunk and rear body panels, with estimated repairs of $5,000–$15,000. My primary concern is that FSD apparently failed to detect or respond appropriately to a stationary vehicle directly behind it. Such a failure could have caused serious injuries if a pedestrian or child had been present. Additionally, I requested my vehicle data from Tesla, but the "Video Recording" section was empty. I am concerned about the missing footage and the availability of critical evidence needed to determine what happened. I respectfully request NHTSA to: Investigate the suspected FSD…”

“On September 26, 2026, my 2024 Tesla Model Y (53,000 miles) suffered a total electrical failure. The vehicle became completely unresponsive — it would not power on or enter Drive mode — and my family was locked outside with no way to access the vehicle. Tesla Service Mode diagnostics (run September 29) showed: HVP LV Power Test FAIL with "Contactor power failure detected" — the high-voltage battery contactors would not close. Also present: drive-unit graceful power-off alert (DI_a063), BMS error, and charge-port communication loss (CP_a060). Tesla has issued campaign bulletin SB-24-16-005 (September 2024) acknowledging that a defective component inside the High Voltage Controller on 2023-2024 Model 3/Y "may prevent the vehicle from entering into drive mode, or may cause a graceful poweroff." Tesla classified this as non-safety-related. However, a sudden total loss of vehicle power — which other owners report occurring at highway speeds — creates crash risk, and inoperable doors create an entrapment and access hazard, especially for families with small children. I request NHTSA investigate whether this defect warrants a safety recall.”

“It has been towed to Tesla 5 times in the last 6 months. The car will all of a sudden do ALL of the following. Hood pops open Tailgate starts to go up and down The car lights start to flash - all of them The heater goes on 100 percent The seat and steering wheel warmers are activated The horn blows constantly The windows go up and down The stereo goes on full blast I cannot stop any of these things from happening. Tesla has had the car 5 times and said it is all repaired but it comes back every time. I cant trust driving the car anymore”

“The contact owns a 2024 Tesla Model Y. The contact stated that while driving at an undisclosed speed on the I-95 N to 175 W exit ramp, while approaching a traffic light in slow-moving traffic with the self-driving feature engaged, the vehicle failed to slow down as expected. To avoid a crash with the vehicle ahead, the contact veered to the right, leaving the roadway and traveling onto a slope and into the grass, where the vehicle struck a tree branch. There were no warning lights illuminated. A Police report was filed. There were no reported injuries or air bag deployment. The insurance company was notified of the issue. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was notified of the issue, and a case was opened. The failure mileage was approximately 19,891.”
