Example complaints
Transmission and drivetrain: “I was almost involved in an accident on the highway last night, either the transmission or the real axles broke as I was driving 70 MPH.

NHTSA complaint #11372526, filed 2020-11, 49,000 milesBrakes: “I had adaptive cruise on, was at a stop light, so adaptive stopped, the truck in front of me moved because the light turned green, so to engage the cruise I gently gave it gas and I felt the cruise kick so I moved my foot and then the car lunged into the trailer hitch of the truck in front of me. I had no time to react, the crash warning did not flash nor did the braking assist engage. Luckily the guy I hit was not affected the hitch prevented damage to his truck but my car took all the damage. …”
NHTSA complaint #11139619, filed 2018-10, 42,200 milesOther or unknown: “The cue system is cracking and non responsive to any touch input.
