NHTSA Complaint #11586994 — 2019 TESLA MODEL X

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.
