1 Automatic Emergency Braking problem

Failure Date: 02/11/2025

A loud popping noise heard through the radio when light pressure applied to brakes. Noise loud enough to scare the hell out of all the occupants in the car. Brakes squeaked when car was in reverse. Tried to slow down on wet pavement. Car started to veer to the right. Forward collision warning nor automatic emergency braking worked. Pushed brake all the way to the floor and the car did not slow. Rear ended another car. No airbags deployed. My passenger was okay. I got diagnosed with a concussion. Do not know if the occupants in the other car were injured.

2 Automatic Emergency Braking problem

The car will all of a sudden make a loud popping noise through the radio. It is enough to scare someone while they are driving and have a wreck. The brakes are very touchy to the point of almost giving you whiplash.

3 Automatic Emergency Braking problem

Failure Date: 07/26/2021

Was in the middle of a 3 car collision. After about 5 min engine started smoking and a fire started. Fire slowly escalated and fully engulfed the entire car.

4 Automatic Emergency Braking problem

Failure Date: 07/22/2021

I have had multiple issues with the car since I've purchased it. The brakes continuously make noise, and the automatic emergency braking does not work. The tire pressure sensors don't work, they have the wrong tire pressure for each tire, and the tires constantly over inflate. Also, my front bumper is coming off. I've taken it to the dealership for all of these things, the dealership said the brakes seem fine, the front bumper clips seem to have warn down for some reason, and that they reset my tire pressure. There was no permanent solution. They put a band aid on my problem and I still have all of these issues.

5 Automatic Emergency Braking problem

Failure Date: 02/06/2021

The brakes including brake assist stopped working. Pressing the brake pedal did little to stop the vehicle. There was recall for this same issue that was preformed by the dealership 3 weeks ago.
