2023 Tesla Model 3 electrical system problems

“The vehicle was purchased pre-owned directly from Tesla. On the day of pickup and five days later, while operating on Full Self-Driving (FSD), the vehicle phantom-braked abruptly and then dangerously accelerated through a solid red light into cross-traffic intersections. The driver had to forcefully override the vehicle to prevent a crash. Tesla Service Center was notified but dismissed the issue, performing only a camera recalibration and charging a fee. Following the service appointment, the red-light running behavior stopped, but the vehicle continues to suffer from aggressive, sudden phantom braking multiple times on every single trip, creating a severe and continuous risk of a rear-end collision on public highways.”

“During Autopilot, the vehicle failed to recognize the curve (or did not input enough turning to steering) and accelerated at the curve thinking it is a straight to almost have me crash into a guard rail. No symptoms. No side damage or collisions with others.”

“I am reporting a serious safety incident involving a 2023 Tesla Model 3. On March 29 at approximately 5:00 PM, while driving on the freeway at about 65 mph, the right-side passenger door suddenly opened while the vehicle was in motion. The door had been fully closed and latched prior to driving. There was no impact, obstruction, or warning indicating that the door was not secure. The opening occurred unexpectedly during normal driving conditions, creating a significant safety risk. After the incident, Tesla was contacted and indicated that a diagnostic inspection would require a fee, and they suggested the possibility of prior modification or tampering but did not provide a confirmed cause. The vehicle was purchased from a used car dealership, and the incident raises concerns about a potential mechanical or electronic failure of the door latch system and the safety of the vehicle as sold.This issue poses a serious risk to occupants and other road users, particularly at highway speeds. I am requesting that this incident be reviewed as a potential safety defect.”

“Door cannot be opened during power loss / emergency. I am a Tesla Model 3 owner in California. I discovered that the rear doors do not have a mechanical emergency release. Tesla service confirmed that my vehicle does not include any manual rear emergency door release system. This raises a serious safety concern because, in the event of a crash, fire, or 12V power failure, rear passengers—especially children or elderly occupants—may be unable to exit the vehicle. I request NHTSA to investigate whether the absence of a mechanical rear emergency release complies with FMVSS 206 and whether Tesla’s design poses a safety risk during emergency egress.”

“The rear doors intermittently will not unlock. Even after hitting the unlock button from menu or short or long press of the driver unlock button or from the app unlock button. The driver only unlock feature is disabled. I have video that would not upload. Snapshots of video included.”

“An incident that occurred while Full Self-Driving (FSD) was engaged. During the drive, the vehicle unexpectedly steered toward the curb while making a right turn. I was actively monitoring the vehicle and immediately took control of the steering, but the vehicle still made contact with the curb. After the incident, the vehicle developed steering misalignment, vibration while driving, and abnormal noise, which suggests possible suspension or wheel damage. Since FSD was engaged at the time, I would appreciate it if Tesla could review the vehicle logs and investigate whether there was any system malfunction or unexpected behavior from the FSD system.”
