During a recent incident where a tire issue caused damage to the wiring harness for the parking brake, resulting in a parking brake failure notification on the screen, the vehicle would not stop or turn off. The vehicle displayed n for neutral on the dash, but the vehicle would drive forward unless the brake was depressed. In addition, we were unable to place the vehicle in park, which meant that we were unable to shut it off. The only way to stop the vehicle from driving on its own and crashing into something was to place concrete blocks under the tires! unplugging the 12v battery also had no effect! the vehicle kept driving as if it was in drive, and there as no way to stop it without placing the foot on the brake pedal the entire time or placing the blocks I referenced. The only way I was able to shut it off, was to pull what's known as the fireman's loop, which I'm guessing firemen pull in the case of an accident. I wasn't aware of this mechanism, and only learned of it after posting on numerous social media apps regarding this issue. This is a major issue, as we are talking about a moving and unstoppable car! Tesla needs to build some mechanism that allows the car to be shut off by the driver or to override the screen and place the car in park. Pulling this firemans loop and unplugging the 12v battery, required me being in front of the vehicle, risking my life, as the vehicle could've easily moved if the concrete barriers didn't stop it, and also required me taking 30+ minutes to remove components from the frunk, just to access these components!!.
While on cruise control (autopilot) on the highway, the vehicle occasionally violently slows down. The majority of the time, this happens near or just before an exit/entrance ramp and if the car is in the rightmost lane. It happens regardless of traffic conditions and even if there are zero cars around, it will still "hiccup" and hit the brakes. I've noticed that the cruise control system sometimes automatically changes the maximum speed for the cruise control to 35-45 mph which explains the sudden braking. It is semi-replicable by setting the cruise control to a comfortable highway speed (say 65 mph) while the car is in the rightmost lane, then driving past a (normally) heavily trafficked entry/exit merging area. If requested, I can probably find a safe time and area to replicate this and send in my dashcam footage of the incident.
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. I could not even get assistance from them on getting service for the car. They kept pointing me to the mobile app on the phone which would not function properly and after typing the incident into as I wrote above 3 times I gave up.
All screens in the car shut down while driving and there is no access to your speed, blinkers, control of lights, control of car safety features, wipers, etc. Tesla was notified multiple times and each time they tried to correct the issue, it was not resolved. It has been a year since the issue started and has happened over a dozen times, resulting in unsafe driving conditions. Tesla keeps stating they "remotely diagnose" the problem and told me to keep an eye on it and see if it happens again, although they told me less than 2 weeks prior to call immediately if it happened again. They have refused to fix the problem and it has become a safety issue with driving the vehicle.
As the vehicle self driving system was active it came to a full stop in a red light. The vehicle stopped behind an 18 wheeler. As I was in a full stop, I stopped looking to the front of the car and looked for a document and checked messages. Suddenly the vehicle accelerated fully, impacting the 18 wheeler in front of me. My reaction was not fast enough as I was very confused, eventually I hit the breaks and activated abs system but not with enough time to stop before impact. This has been confirmed by the Tesla report that the vehicle acceleration occurred with out drive input. They seem to ignore the fact that I was at a red light and state it is operator error not to be attentive, but regardless, accelerating at full speed with no input towards another vehicle is a hazard to the population. They have not shared the report from engineering, only read the statement over the phone once and have not been able to ask for the written report. Significant avoidance in occurring from the company.
We had an accident 2days ago. We were in the school loop to drop off our son to school. My husband was driving and was heading towards the drop off area when everything just happened so fast, the next thing I knew is that we hit one of the in-ground installed basketball hoops. The impact was hard and deployed all the airbags on the passenger seats and the side airbag of the driver and the 2nd row passenger seats where my son was seated and also saw some smoke from the front where I was seated and I do not know where it was coming from that I thought that the car was on fire but my husband informed me there was none. Recalling now, it has been a mystery to us as to why and what really happened. I was seated on the front passenger seat and sustained a fracture in the right scapula and generalized contusions in my body area. My son who was seated on the 2nd row also sustained contusions on his face and a few lacerations. We were coming into the school loop and was running on a somewhat 20mph speed, I was wondering if the vehicle did accelerate it's speed cause why would we have such a hard impact and sustained those injuries that it even deployed almost all the airbags? hope someone can look into this so as not to have anyone be on our same fate and for everyone's future safety. Thank you.
The contact owned a 2018 Tesla Model X. The contact stated that as her husband was parking in a space, the vehicle made a loud noise and accelerated independently. As a result, the vehicle crashed into a tree and a cement planter, causing the planter to move about 10 feet away. There was no warning light or chimes. The contact was asked about air bag deployment and confirmed that no air bags deployed. The contact who was the front passenger and at the time of the failure was bending over to grab her purse from the floor mat sustained a bruised rib and later drove herself to the doctor for medical attention. The police was called to the scene but the contact was not sure if a police report was filed. The vehicle was totaled and towed to a salvage lot. The contact called the Tesla motors dealer (650-681-5800, located at 4180 el camino real, palo alto, CA 94306) and was told to email the information. The contact emailed the information but did not get a response. The failure mileage was approximately 8,000.
Using the self-park system, from a stationary position and pressing the touch screen prompts to use the self-park, and having hands and feet away from the gas, brake and steering wheel, and parking between two cars, the car accelerated backward on its own and I had to slam my foot on the brake to stop it but it still hit a pole going in reverse and damaged the body of the car. Had I not hit the brake my son and I would have been injured. Tesla has denied responsibility.
A Tesla Model X was able to be started and shifted into gear by a 2 year old who was then able to drive the vehicle forward and pin his pregnant mother between the vehicle and garage wall. Apparently there are no safety-interlocks preventing starting of the engine, such as transmission in 'p' or 'n'. Further, there is a wand shifter, but gear selection is completely under software control. There is no interlock such as with a traditional prndl selector. This is an inherently unsafe design. Civil docket describing the accident and Tesla's response are attached. Note in Tesla's response: 1) they do not state how many minutes elapsed between driver exiting the vehicle and toddler entering it. They use the vague term "moments. " it could well have been 10 or 15 minutes. 2) they claim it is not reasonably foreseeable that a child would manage to shift a vehicle into gear, which is patently false. Safe vehicle design absolutely includes consideration of unsupervised children playing at the controls.
When slowly pulling into a parking spot, the car accelerated on it's own jumping the curb and slammed into a chain link fence. I pressed the brake pedal but it didn't respond. My ten year old child was in the back seat and thankfully we are both unharmed. This is the second incident of the car accelerating on it's own. The first time this occurred was during my first week with the car and when I was slowly driving around a traffic circle in a residential area and the car took off on it's own. No damage other than misalignment that time but I was very scared and called Tesla service. It took several weeks for them to respond with the data report from the car and said that the vehicle increased speed due to the driver pressing the accelerator. I accepted their explanation and assumed that I was indeed at fault even though I was positive that I didn't press the accelerator. I'm incredibly saddened by this situation as I truly loved this car but I'm too frightened to drive it again. It's currently at a body shop.
The contact owns a 2018 Tesla Model X. While pulling into a parking space, the brake pedal was depressed but the vehicle inadvertently accelerated over a curb before crashing into a cement light pole. The front end of the vehicle was severely damaged, and the air bags did not deploy. The driver sustained neck, shoulder, and chest injuries that required medical attention. A police report was filed. The vehicle was towed to a tow yard. On several occasions, prior to the failure, an erroneous warning message displayed while driving, indicating that the vehicle was driving too closely to the preceding vehicle, even though another vehicle was nowhere in the vicinity. The contact indicated that the failure occurred on multiple occasions, including shortly before the crash. The manufacturer was notified of the failures. The local dealer was not contacted for diagnostic testing or repairs. The failure mileage was 1,500.
