2019 Tesla Model X Speed Control & Cruise Problems

While I was driving, I got an error on my dashboard that "acceleration and top speed reduced. performance may be restored on next drive". After I got this error, from onwards the car was not slowing down even though I remove my foot from accelerator and sometimes it is accelerating itself even though I was not on cruise control or auto pilot. Luckly brakes were working when it was causing sudden unintended acceleration. After I stopped my car at safe location it did not start, and it got towed to Tesla dealer. My concern is that I felt it is most dangerous and it can cause life threating accident. Could you please take necessary action on this incident which causing sudden unintended acceleration. Thank you, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

When operating under adaptive cruise control, the vehicle frequently slams on the brakes for no reason. This has become so bad that we are simply terrified to operate the vehicle under adaptive cruise control. The highway is completely empty in front of us, there are no hazards and no issues with visibility on the road. The cruise control simply reacts to a phantom in a highly dangerous manner. > What component or system failed or malfunctioned, and is it available for inspection upon request? The adaptive cruise control - you are welcome to inspect it. > How was your safety or the safety of others put at risk? We have suffered two near-miss rear-end collisions at high speed on the Interstate. The behavior throws us against the seat belt restraints, causing near loss of control. > Has the problem been reproduced or confirmed by a dealer or independent service center? We have raised the problem repeatedly with Tesla, and there are numerous confirming reports by other Tesla owners > Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The system has been checked by Tesla, nothing found wrong. Tesla maintains that they are continuing to "train" the system, but after 5.5 years, there has been no improvement. > Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Nothing - the car simply slams on the brakes.

I'VE HAD MY TESLA SINCE DECEMBER 24TH 2019. THE CAR WAS GIVEN TO ME WITHOUT A TEST DRIVE AND SAID TO HAVE A SEVEN DAY GUARANTEE. THE CAR WAS DEFECTIVE FROM THE MOMENT I GOT IT, AUTOMATICALLY ACCELERATING AND ACTING SPORADICALLY WHEN ENGAGED IN AUTO PILOT. THE BATTERY LIFE IS HAS OFTEN BEEN ONE THIRD OF WHAT I PAID FOR AND TESLA WILL BE 'SERVICING' IT FOR THE THIRD TIME TOMORROW. THE CAR IS DANGEROUS AND NOT RELIABLE. THEY WOULD NOT TAKE MY CAR BACK BECAUSE THEY TOLD ME I WAS PART OF A GOVERNMENT REBATE THAT INVALIDATES MY ABILITY TO RETURN THE ERRATIC VEHICLE WITH POOR MILEAGE. AMONG OTHER ISSUES MY CAR ALSO HAS WINDOW ALIGNMENT ISSUES BUBBLES IN PAINT DEFECTIVE CAMERA DEFECTIVE SENSOR MISALIGNED WINDOWS AUTOMATIC ACCELERATION WHEN NOT SUPPOSED TO STEERING ISSUES DEFECTIVE AUTOPILOT STRANGE SOUNDS AND MORE
