Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“On mar 1, 2021 while driving super cruise mode, my car jerked violently to the left almost striking another car. I was on the fl turnpike about 20 miles north of orlando heading south. The highway was increasing from 2 lane to 3 lane southbound and I was in the right lane. When I entered the lane transition, the car drifted right . As the car came upon the new white line the car about centered it. The car turned hard left, and turned off super cruise. Fortunately, I was able to grab the steering wheel and correct the turn. We did not crash, but it was most unsettling.”
