My steering wheel started vibrating vigorously, a clanking sound started under the hood somewhere, and none of my safety features worked after.. Cruise Control, Vehicle Collision Control, Vehicle Gap sensors, etc.. The vehicle is currently at the dealer being looked at.”
NHTSA complaint #11435985, filed 2021-10“While driving home from work around 6 am, my car had multiple warning lights and warning messages come up all of a sudden. Immediately after that I lost my power brakes and steering and was not able to control my car at 40 mph. I was lucky the light I passed was green and there was no other traffic. I was able to bring my truck to a stop after more than a quarter mile by putting all my weight on the brake pedal. The truck was towed to the dealer and has been there ever since.”
NHTSA complaint #11517110, filed 2023-04“Driving the car it started backfiring and then the ESC light came on and the car engine seemed to become erratic as well as steering and braking error messages and the check engine started blinking. Very scary before I got it pulled over and very thankful I wasn’t on the highway etc. I’m seeing all the issues online sounds like the supposed fixes for the 2019 models having issues aren’t solving the problem. I bought mine in April and 4 months later it’s become unreliable.”
