I took an exit form the highway on i405 towards bothell. As soon as I did and ended up coasting towards the first red light, all the warning signs came on on the car and my steering wheel locked up. And my braking also got reduced. Only thing that worked was the acceleration pedal. I struggled to get the car towards any safety. There was a message on the dashboard saying that assisted steering is reduced will require more power. However it was locked. I tried with all my might to steer the car in any direction but it would not budge. I was super scared I was going to be in an accident. With the limited braking as well I had to find a curb in the road to be able to safely park the car or a slope where the car could slow to a halt. Luckily I was able to do that and slowed down. On a curb like area and then I was able to turn on the parking brake. On contacting support they told me to reset the car and in doing so it should bring back functions. However, it did not. This was extremely dangerous and I was very lucky to get out of this alive without harming anyone else as well. Had this happened on the highway I was a sure goner. They had to finally get the car towed from there.
The contact owns a 2023 Tesla Model X. The contact stated that while stopped at the driveway and waiting for the gate to open, the vehicle inadvertently accelerated, struck the gate, and came to a stop. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 8,000.
Issue is with Tesla full self driving subscription for $199/month and is available for inspection. No warnings or symptoms were indicated. The vehicle recommended I re-enable the service every time the vehicle restarted after it was shut off. Tesla's phone support stated the following is normal expected behavior, so an inspection isn't needed: 1. Automatically changed lanes on interstate into the space occupied by another vehicle multiple times. Thankfully, crashes were avoided by attentive drivers of involved vehicles. 2. Confused "40 mph minimum speed" signs for speed limit, resulting in over 30 instances were speed was drastically and suddenly reduced, without warning, every time the sign appeared. 3. Automatically changed lanes on interstate from rightmost lane to center lane despite no traffic present. This seems to be a default behavior that cannot be adjusted. 4. Disabled cruise control and lane keeping assist when driver overrode automated systems (accelerated, braked, manually adjusted steering) to avoid a crash. Kept these systems disabled as a punishment until driver parked car and restarted.
As I drove my Tesla Model X plaid into my driveway towards the garage to park, the vehicle suddenly accelerated itself (I have fsd but wasn’t using it at that time) and drove into the garage door as it was still opening, slamming and crushing into all the items that were on one side of the garage. When I quickly realized what was going on, I slammed the brakes and made the car stop. My daughter luckily was waiting for me on the stairs of the garage. If she were standing in the garage instead, it would have been fatal. I have already called Tesla about the incident and they said someone will visit and take a look in about a week. This happened on Sunday sept 17th 2023 around 8 pm. When I bought the car in Dec 2022, as soon as I took the delivery of the car, I have experienced the front driver and passenger windows that kept opening by themselves multiple times. I had called Tesla and they replaced both the doors and it didn’t happen again after that. I asked the technician at the time that if the car can’t control such small things, how can I trust my life with its fsd? he assured me that this was the safest car and had multiple sensors that are constantly monitoring the safety of the car, but in my case I am shocked to see that the sensors didn’t do anything to stop when the car slammed itself into the garage.
When driving at highway speed and using cruise control, the car periodically applies its brakes. Sometimes it will only do so for a second or two, then return to the cruise control speed; other times it will continue longer and I will have to intervene by applying pressure to the accelerator pedal. In shorter "phantom braking" episodes the speed may only be reduced by five or ten miles per hour; in longer episodes it could drop by twenty miles per hour before I intervene. I have driven the car for almost three months and have experienced this no fewer than twenty times. To be fair, I have driven almost nine thousand miles during that time, so I have spent a considerable amount of time on highways. When communicating with Tesla's service department, I received a reply message reading, in part: ". . . Slowdowns for apparently no reason are generally caused by a few reasons . . . This can easily be overridden by pressing the accelerator pedal . . . There are no faults with any of the driver assistance hardware in the vehicle . . . These behaviors are a limitation of software in the system . . . A service visit is not needed at this time. " I have owned cars for almost forty years and have never had these issues while using cruise control. That Tesla finds this acceptable is absolutely not acceptable. I believe it is an unsafe condition, as I have no control over drivers behind me and how they may act in the case of my car decelerating for no apparent reason.
