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!!.
Based on thousands of posts, replies, etc, this seems to be a well known issue with this model/year Tesla as well as other years/models. It seems that the wheel sensor cable is not fastened properly, and over time, the cable runs against the tire, causing the internal wires to be exposed, this in turn causes numerous faults to occur, which includes causing abs, lane departure avoidance, traction control, stability control, abs, and regenerative braking to stop working. This happens while driving resulting in an immediate change in how the vehicle functions which could easily lead to a major accident while there are numerous forums where this issue is noted, below is one that details the issue with photos [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
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.
On may 15. 2022 at 4:25pm while traveling north on highway 395 about 14 miles south of bishop californa. While traveling with little to no traffic, using adaptive cruise control (not self driving) the vehicle suddenly stopped for no apparent reason in the middle of the highway. Fortunately, there were no cars behind us otherwise I probably would not be writing this. I have registered a similar complaint back in March for the same issue. We have had a total of 4 “phantom braking” incidents since buying the car in October 2021.
Our Tesla has had the “phantom braking” on 3 occasions. The first incident happened on southbound interstate 5 near firebaugh. Right after we purchased the car. The car suddenly stopped from 70 mph to about 25 mph in the middle of the freeway. The second event on northbound 395 at 2:45pm 3/20/2022the car went from about 60 mph to about 25 with out warning. It happened once again at about 4:03pm the same day. All of these events occurred while the car was in adaptaive cruise control, it in self driving mode. I have one event on video, that showed skid marks ahead at the same time the braking occurred.
I was driving down a ramp and the emergency brake engaged, causing all of my belongings in my passenger seat and rear seat to fly off the seat. It felt like whiplash and my daughter was in the backseat as well. The next day, I had severe neck and upper back pain to the point that I couldn’t move. I am seeking care with a chiropractor.
On March 1, 2021, wife and I was driving east bound on route 80 highway in ohio. Twice the vehicle braked while driving in cruise control. It was a clear day. There were no cars around. No bridges or obstacles. And the road lines where clear. The first braking occurred while we were on right lane on a two-lane highway. The second braking occurred (around 5:15pm) while we were in the middle lane of 3-lane highway. We were driving approximate 65mph. At both braking, my wife was driving. When I happen, we both confirmed there was no cars or obstacles around us. We contacted Tesla, who after reviewing their logs says it was working in "normal". That the vehicle saw something and braked. Even though both myself and wife can confirm there was nothing around us, particularly since covid has significantly reduced any traffic. There has been a history of issues. On other occasion, one of my side doors indicated there was something there, even though I was the only vehicle in completely empty parking lot. Only after many complaints an attempts did they finally replace the sensor. It seems that they are repeating their denial of claims by two eye-witnesses of the issues.
Starting especially so on this date, and on occasion before this time, the vehicle would abruptly brake very aggressively when I was passing a semi truck with his emergency lights on or when perhaps passing a shadow or for no reason at all. I would have to slam on the gas to avoid a collision or being rear ended.
It happened on freeway 57 when I was on the way to work in the early morning. I was driving my Tesla Model X, and in the autopilot mode. Supposedly in the autopilot mode, Tesla will detect the speed and the object in front and slow down or accelerate. If Tesla is too close to an object, it will beep and stop. But in that morning, the car slowed down but did not stop. And also there is no 'beep' the warning sound when car is too close to the car. Because the video is too large, I can not upload so I put sharing link you can review: https://drive. Google. Com/file/d/11h_pdlkslg0jarlnkevf9ytf6wk0hwkd/view?usp=sharing. Also I called Tesla and reported same day, I had been told they will investigate and call me back but it never happened. Accident happened on April 29 2019, and it has been 4 months. Tesla is still ignoring every call I made in the past.
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.
