Owner reports
Selected complaints filed with NHTSA by 2018 Tesla Model X owners, lightly cleaned up (personal details are redacted by NHTSA).
The Full Self Driving System failed to operate correctly. This caused my car to hit another car. I have asked Tesla for the data they use to tell what the driver was doing when the system was on but the Tesla staff who respond to my requests plead ignorance of what data I am referring to. I am not ready to spend the money it would cost to hire a lawyer to force Tesla to hand over the data from their system. I have video from the Tesla camera showing what happens. I will try to upload it. Here is a quick run through of what happened: I entered the freeway and got into the left lane. Once I was safely in the left lane and up to speed I turned on the FSD keeping my hands on the steering wheel. After a few moments the car veered to the right, I tugged against the pull of the FSD and got it back in the lane when all of a sudden it turned my wheel hard right into a minivan. …
While driving on an interstate freeway on 8-14-2021, using the vehicle Autopilot driver assistance mode (which I had been using for the previous 18 months without incident), the vehicle failed to avoid hitting the vehicle in front of me. This collision resulted in no passenger injury, but resulted in both driver and passenger airbags to engage and resulted in total vehicle loss of the Tesla Model X. No other vehicles involved had airbag engagement. Tesla may have actual information on the functioning of the vehicle and the Autopilot software that may explain why the collision avoidance system failed, but refused to supply me with this information.
While driving on FSD (Full Self Driving) the vehicle was turning off the road into a parking lot and sped up and hit a vehicle while I was pressing the brake to the floor! I had to brace for impact when I hit the vehicle. I have requested the data and telemetry logs from Tesla. Everything was fine before the crash. Husband had a similar incident a few weeks ago where he was turning with FSD engaged and the vehicle stopped in the middle of the turn with a vehicle coming right at him, he had the gas floored to get out of the way but was completely stopped, could not move for 15 seconds or so.
My wife was driving the car in was turning left on to a major road, she apparently hit another car trying to turn right on to the major road from opposite side. Both cars must have started from a stop sign and neither of them knew the speed. My wife does not remember the details of the incident, she was shaken up, initially declined to seek medical care but soon after could not recognize people, so had to be taken to ER. The car with all the technology failed to alert the impending crash, did not apply emergency brakes, nor did not record the event which it was supposed to have.
I was driving on the highway on Tesla enhanced auto pilot when traffic came to a stop I'd notice my Tesla model X was not about to stop nor slow down for the stopped traffic so at the last minute I had to slam on my brakes and swerved to the right lane where I was hit by a truck pulling a trailer which subsequently rammed me into the truck I was trying to avoid rear ending after Teslas forward collision warning failed to notify me or stop the car from crashing in the first place
The contact owns a 2018 Tesla Model X. The contact stated that while driving at approximately 70-75 MPH with the cruise control activated, the vehicle experienced phantom braking. The vehicle was taken to the dealer, but the dealer could not duplicate the failure. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 41,200.
https://youtu.be/yRdzIs4FJJg "Autopilot is set to shut down 1 second before any impact. Makes the driver 100% in control before an accident. Makes the driver 100% responsible. Tesla has killed two motorcyclists in the past 4 months. At night the ai can't tell the difference between a motorcyclist up close and a car far away. So, it assumes car and runs right into it. Another interesting issue with teslas autopilot. They claim its 10x safer than a person. That not true. The claim is based on sheer accidents per mile. Autopilot is only really used on the highway, eating up miles quickly and in an environment where, although consequences of crashes can be more severe, they happen less often. When adjusted to compare highway driving autopilot to highway driving people, it's really only about as safe as a person, if that. In their 2022 cars tesla has done away with radar. …
While driving at speed approximately 4:20PM EST April 9th, 2022 on I95 near the Georgia/South Carolina border the onboard computer froze and became unresponsive, including the speedometer, the radio, navigation system, etc.. I became aware of the issue because the car started to slowly slow down but the display continued to show 70 MPH. I forced the computer out of Autopilot but the car continued to show it was in autopilot. shortly after the display behind the steering wheel went blank then rebooted, followed by the center console. thankfully I was paying attention and did not panic, had I panicked I could very easily been in an accident as I did not know what was going on with the car. I reached out to tesla multiple times following the incident and the agents and agents were non-caring and treated it as no big deal, and acted as if I should not be concerned about it. …
On Oct. 26 at approximately 5:45 p.m. on HWY 26 near Sandy, OR the autopilot system failed by abruptly turning the car into the upcoming turn lain (marked with solid white line) and towards oncoming traffic. I had to immediately take significant corrective action to move the car back into the lane I was traveling. I firmly believe that the car could have cross into the lane going the opposite direction. I definitely was very unsettled by this event. This type of spontaneous autopilot error has occurred numerous times in the past to me (have driven a Model X Tesla since 2016) and I now very seldom use the feature while driving. I have taking no further action regarding this event or others because while under warranty Tesla always come up with rationale that they couldn't find a problem because of loss of connectivity, could not detect a problem, etc. …
I was driving on [redacted] from Carson City to Reno in Washoe Valley while on autopilot, the car suddenly alerted with very loud alarms, showed 1. steering assist reduced, 2. Automatic Emergency Braking is unavailable 3. Traction Control disabled 4. Stability control disabled 5. Park Assist unavailable. I pulled over to a safe parking area. Then the car locked out for 75 mins, in Neutral gear, can't shut off, can't park, can't reset the car at all even after talking to Tesla support. While waiting for the tow truck, I turned it into Tow mode, was able to change into Park mode finally, and hard reset the car. I took it in and Tesla told me the steering system was the problem and I was out of warranty so I had to pay A LOT OF money to repair/replace it.
