What owners say
I have been driving my Model S Tesla for 13 years. On 30 April as I was pulling into a parking space at my local grocery store, I applied the brakes to ease into the space and my car surged forward with unintended acceleration. I smashed into the concrete base of a light pole, the airbags deployed and my car ricocheted back about 8 feet. There were no warning messages. I was taken to the emergency room and had whiplash and a burn on my leg from the airbag. No one else was hurt. I know it was the car that malfunctioned because my foot was still on the brake after the collision and the airbags bruised the right side of my right leg. It could not have bruised it in that way if my foot had been on the accelerator. The insurance company inspected and declared a total loss. I obtained the black box data from Tesla and am uploading the documents below. The car is currently at the Tesla collision center. They do not seem interested in evaluating the problem.
I pulled my Tesla Model S in a parking lot, and as I turned the car into a parking spot, the car suddenly accelerated, jumped the curb next to the parking lot and hit a tree. The car speed when I pulled into the parking lot and then into a parking spot was very low. so I was very surprised and startled to see the car suddenly on its own accelerating and jumping the curb.
I was parking the car and gently tapped on the accelerator to inch forward. The car accelerated suddenly, crashed into a concrete sign holder, and knocked down a sign, until I was able to stop it using the breaks. The accident caused $5000 worth of damage that I paid out of pocket to fix, since I assumed I must have made a mistake. However when I got the car back a month later, unintended acceleration happened AGAIN - under the same circumstances. I was parking and inching forward. I tapped the accelerator and the car accelerated suddenly. This time I was able to stop it before causing any damage. At this point, I KNEW that the first accident was not my error, since it had now happened again, and I was 100% sure that I did nothing wrong. I looked up "unintended acceleration - Tesla" and found examples of the exact same thing happening while parking. I looked for a fix, and it suggested changing the mode of the car to "creep." This so far has worked well.
CRITICAL SAFETY FAILURE: Loss of Driver Override and Extreme HMI/Signaling Latency. 1. Loss of Override & Unintended Acceleration: While operating FSD (Supervised), the vehicle ignored a 65 mph set-point and accelerated to 80 mph. I attempted to reduce speed by pulling down on the steering stalk 4-5 times, but the vehicle ignored all manual inputs, requiring a hard disengagement. 2. Lane Departure / Path Failure: The vehicle failed to maintain lane centering, specifically crossing over the centerline into opposing traffic. This occured without warning or system-initiated steering alerts 3. False Signaling / Path Failure: I’ve seen at least two occurrences where system exhibits dangerous signaling conflicts, such as activating a right-turn signal while simultaneously executing a left-turn maneuver. One time it was on a 45–55 mph rural corridor where trailing drivers frequently overtake slower vehicles. A false right-turn signal acts as a dangerous "all-clear" for a trailing driver to pass on the left, creating a high- probability broadside collision scenario when the Tesla physically executes its left turn. I have no idea if this has occurred more than these two times as I don’t check this. The other time I caught on video, by chance, as I was trying to capture the surging behavior to show the Tesla service center 4. Audio & Visual HMI Latency: Audible instructions arrive 100+ feet after turns, and the map UI auto-zooms away from the driver’s focus, requiring constant manual screen contact to view street names. This forces significant Visual-Manual Distraction. 5. Confirmed Inadequacy: Tesla Service Invoice #[XXX] (Jan 27, 2025) documents: 'The current computer is a little too slow for full self driving function...' confirming the hardware is unfit for safety-critical processing. This incident is directly relevant to the federal safety agency Investigation PE25012. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Approaching my garage door as it was opening when the car suddenly accelerated smashing through the garage door, through the back wall of the garage, through the laundry room and finally stopped in the main bedroom with the front wheels off the ground as the car rested on top of the washing machine.
As I approached a red light with a car in front of me, I took my foot off the accelerator to use Tesla's regenerative braking, but instead the car rapidly accelerated and crashed into the car in front of me. It seemed like unintended acceleration.
The contact owns a 2016 Tesla Model S. The contact stated that while turning into a parking spot, there was an unintended acceleration of the vehicle; it surged forward, jumped the parking barrier, and crashed into a wall. There were no warning lights illuminated. A police report was filed. There was no reported fire, injuries, or air bag deployment. The vehicle was towed to a body shop. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 93,000.
On September 7th, 2024 around 7:35 PM, my tesla model S 2016 Suddenly accelerated, smashed in the siding of my house breaking the the siding of the wall and was totaled. All of this happened while my mom was trying to park the car in the garage the car suddenly took off without her pressing the accelerator. I have tesla to send an engeneer to collect the data of the car in which they said they did but have not yet gotten back to me on the issue. They informed me that they have collected the data on 09/20/2024
I pulled into a driveway on a one lane road (due to construction) to allow a car traveling downhill to pass so they would not have to back up. I had come to a complete stop in the driveway with the car in drive. As I started to put the car in reverse it surged forward at a high rate of speed crashing into my neighbor's garage, tearing the door completely down pushing the door into the garage and my car entering the garage at least 15 feet hitting the car that was parked inside and pushing it with such force that the front end of the vehicle struck the garage cabinets tearing them down. My air bag did not deploy nor did the automatic braking system engage, it just sped up as it was doing the damage. The car has been deemed a total loss by my insurance company but i don't want this report to go unnoticed. To my knowledge the insurance company has not inspected the computer on the vehicle. I'm not sure how they will investigate this occurrence. I feel strongly that this was a malfunction with my car. The message that showed immediately was "driver assist unavailable", I have NEVER used driver assist.
