NHTSA Complaint #11470344 — 2017 TESLA MODEL X

Many instances of hard braking in cruise control with no cause. In the last 6 months it’s gotten very bad. It only happened very infrequently before when someone was turning off the freeway it would brake for just a second. Now it is braking hard in an extended fashion and multiple times in one trip. Sometimes we can see some reason, sometimes not. Once, traveling 75 MPH passing a large truck in the lane to my right, the brakes slammed on very hard. Fortunately, I had both hands on the wheel and avoiding crashing into him and the car be him me was far enough back to not hit me. Many other smaller instances, but today doing about 45-50 MPH the brakes slammed on HARD, didn’t release, and I had to steer to the left and hit the accelerator to avoid hitting a biker. I think the Tesla may have been reacting to the biker. I will not use cruise control any longer until it is fixed. It is terrifying and it’s just a matter of time until something really bad happens.
