Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Driving at approx. 30mph and suddenly the entire dash lit up, all red and yellow symbols along with a msg in the display to the effect of collision avoidance system inoperative, stop immediately. This may not have been the exact msg. At the same time the car decelerated to a stop almost immediately. Obviously I did not need to bring the vehicle to a stop. It felt like the deceleration of the engine being off but the car still in gear with that stopping the car. Did not use brakes to stop car. This was very sudden. The engine was not running after stopping because the tach was at zero. …”
