2023 Tesla Model Y Transmission Problems

Mileage when the problem started

Owner reports

Selected complaints filed with NHTSA by 2023 Tesla Model Y owners, lightly cleaned up (personal details are redacted by NHTSA).

The contact owns a 2023 Tesla Model Y. The contact stated while pulling into the driveway, the vehicle accelerated at high-speed causing the vehicle to strike a wall at the contact resident. The contact stated the brake assist did not activate. The vehicle had major front-end damages. The contact's resident wall was damaged. Both the contact's wife who was driving and the passenger suffered concussion and whiplash. The contact's wife suffered neck injuries but neither the driver nor the passenger sought medical attention. A police report was not filed. The vehicle was towed to a repair center. The manufacturer was notified of the failure and the vehicle data. The failure mileage was 3,746.

COMPONENT/SYSTEM THAT FAILED: The service brakes failed to stop the vehicle. While reverse-parking at low (parking) speed, I applied the brake pedal and the vehicle did not stop as expected, resulting in contact with an object and vehicle damage. The vehicle is available for inspection upon request; it has been preserved and driven only minimally since the event. HOW SAFETY WAS PUT AT RISK: The brakes failed with no warning. Had a person been behind the vehicle, the failure to stop could have caused injury. This is the only vehicle for a family with three children who are regularly transported in it, and I no longer feel safe driving them. REPRODUCED/CONFIRMED BY A DEALER OR SERVICE CENTER: Not yet. INSPECTED BY MANUFACTURER/POLICE/INSURANCE/OTHERS: The insurer opened and then denied the claim and stated that no vehicle telemetry/data was available to preserve. …

Location: car wash tunnel Symptom: ghost braking/shifting While in car wash mode and neutral, Tesla shifted inexplicably from neutral to park, causing Tesla to be rear-ended by the car behind in the car wash tunnel. My passengers and I could have been injured. Tesla engineers completed a technical review of the safety incident but refused to provide the full report instead directed me to consult lawyers. On the day of the service appointment, they did not even inspect my vehicle but instead told me to request vehicle data online. It turned out to be a waste of time to download vehicle recorded data that only Tesla engineers understand. The service invoice says, "Verified proper operation of the vehicle." That is false. They did not even admit my car into the service entrance. …

I was about to park in car space in a parking lot. Instead of stopping in the car space, it has accelerated suddenly into the lawn in front of the car space. Tried to stop and it accelerated again and then hit the tree. The left front part of the model Y is damaged and is still in the body shop even after more than a month. I thought the only explanation is I have pressed accelerator instead of break. But as I think about it, I don't think I pressed the accelerator. It did sudden intended acceleration twice during that incidence.

June 9, 2025 Phantom acceleration. No foot on accelerator. Car jumped from 5 to 35 mph. Breaks unresponsive for 3 seconds, smashed into 4 parked cars, creating a Chain-Reaction crash, my Tesla Model Y Totaled, Airbags deployed. Burlington Police Department arrived, took statements, filed report, no copy yet.

Vehicle had a open window during rain storm. Interior got wet. Next day the vehicle was left to dry out. Vehicle caught on fire and engulfed in flames in the backseat. Nobody was harmed fire was contained by the Frisco Fire Department. Vehicle was then towed away.

What component or system failed or malfunctioned, and is it available for inspection upon request?: I got delivery of my new Model Y and odometer was reading 3 miles, i took the delivery and drove 10 miles and it stuck the steering wheel , "rear motor got disabled alert" and vehicle went to slow speed on freeway all of sudden, i had truck behind me it would ended up very bad for me and family, i had to immediately put emergency signal and stop on road side, i tried to call tesla road safety helpline and they were totally busy and did not receive call. How was your safety or the safety of others put at risk? ; this car "rear motor disabled " twice in middle of freeway , Has the problem been reproduced or confirmed by a dealer or independent service center?: Yes they confirmed but unable to give me more details . …

I hit a rock at approximately 35 mph that got projected under my car and caused a bad leak in the battery coolant system. Received a low coolant warning about one minute after the incident. The alert indicated that the car was safe to drive but to schedule service asap. Tesla instructed me to drive to the local SC that is 15 min away when though enough coolant had leaked to render the user display black. I had no turn signals, no speedometer, nothing except the ability to move the car. Tesla alerted me the next day that the damaged occurred at a poorly protected point where the coolant lines connect to the HV battery and that the battery with less than 20K miles needs to be replaced. As a result, they discharged the energy from the battery to avoid a "thermal event". …

On [redacted], the vehicle displayed multiple alerts: "Electrical power reduced," "Climate cabin controller requires service," "Electrical system may not support all features," and "Vehicle may not restart." I scheduled service for May 21, 2024, and dropped the vehicle off at the Tesla Service Center in Fresno, CA. Tesla failed to provide a written invoice for that visit. A service advisor told me "It was a glitch" and that I should check the app, but no documentation appeared. Despite multiple in-person and written requests, I never received a record of the visit. On [redacted], the vehicle failed to start and was towed back to Tesla. A May 24 invoice confirmed a major safety issue-a high-voltage current fault that triggered the Pyrotechnic Battery Disconnect. Tesla later marked the May 21 appointment as "canceled" in their system. …

The vehicle display flashed red and then the vehicle turned off completely while in traffic with no ability to change gear, operate the electronic door releases, or turn the hazards on. Safety was put at risk because insufficient notice of failure was given so it was impossible to get out of traffic, the vehicle could not be put in neutral so could not be pushed out of traffic, further the hazard lights could not be turned on so I had to stand in traffic waiving people around the vehicle. Because the electronic door releases didn't work, the doors could not be opened from the outside, had a front window not been open, it would have been easy to trap our child in the car. The dealer confirmed that the failure took place from vehicle logs but was unable to reproduce the problem. The dealer/manufacturer inspected the vehicle. …
