“Heading westbound on I-70, taking Exit 29 off ramp from highway, I drove over uneven pavement. My traction control, ABS and brake lights illuminated, the brakes suddenly felt mushy. As I approached the stoplight at the end of the exit ramp, I questioned whether I would be able to stop. Scared me immensely. Luckily no cars were near me. I now do not have ABS, Traction Control, stability control OR regenerative braking.”

“My car accelerated significantly on its own while I was pulling into a parking stall in a private parking lot. It caused my vehicle to jump a curb and accelerate up a dirt divider and push over a bush that was planted in the dirt divider. Depressing my brakes did not Decelerate the car, so I pressed the Park button to eventually stop the vehicle. I’m not sure what speed it was traveling when it accelerated, but I could smell burning rubber at the end of the incident. I’m not sure when the smell first occurred.”

“Total malfunction at highway speeds. Very unsafe, the car completely shut off. This may have resulted in a highway fatality due to collision as the vehicle was in the fast lane. NTSA please do your due diligence and investigate the faulty, defective HYBRID system as I believe the faulty inverter recall is much more larger than the original recall”
