What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
While driving down the road a vehicle in front of me braked to stop for a bus loading kids, as I stepped on the brakes nothing happened and the vehicle surged forward.
While attempting a left-hand turn, the steering wheel suddenly became stiff and unresponsive, as if the mechanical gear had bound. This sudden resistance made it impossible to complete the turn, causing the vehicle to strike a curb at low speed.
My brakes failed at a stop light. I was waiting at a red light waiting to get on the freeway . Brake was completely pressed, when my car started rolling forward. I kept trying to apply more force to brakes but was unable to stop the vehicle until it rolled into the car in front of me.
ActiveSense advanced safety and driver support system may not operate correctly." The service department at the dealership where I purchased the car explained that the sensors had overheated due to the hot weather.
The contact stated that while operating the vehicle, the vehicle experienced erroneous Lane Assist and Brake Assist failures, causing the vehicle to drive into the wrong lane. The vehicle experienced acceleration and braking assist failures. Occasionally, the vehicle failed to immediately start.
The RPM increased, and the vehicle stalled without acceleration. There was smoke emerging from the hood. There was oil leaking. The vehicle failed to turn off and on. The fuel gauge and infotainment center were not working properly. The contact stated that while leaving the local dealer, the vehicle stalled.
