“Rear braking system. When backing up or applying pressure to the brakes, the vehicle is screaming a loud noise. Taken by dealership at 7000 miles 01/04/18 dealership states they can't fix it until they receive parts ,with the takata recall and a faulty braking system, this is a highway safety issue.”

NHTSA complaint #11063873, filed 2018-01, 7,000 miles

“When the vehicle is in motion, or still, the driver's side cover for the seatbelt/airbag will not stay attached. This is located on the driver's seat and is visible when entering and exiting the car. I am not really concerned about the cosmetic issue as much as the safety issue. With the side impact airbags, this is a safety hazard. If the bag deploys who knows what will happen to the floating part? Will the airbag, or seatbelt even deploy, or work as it should? This is also a safety issue because you can be injured by the hard plastic that is hanging there. …”

“No incident my vehicle has a front left malfunction service required light and issues with the passenger seatbelt not proper latching. Upon checking I notice my car had previous recalls done. It seems as if the same issues has come about. NHTSA: 18v177- seat belt not retracting properly. NHTSA: 17V627 is related to the steering column switch replacement of clock spring. So if me or a family member was to get into an accident no airbag will deploy! Huge safety hazard!”
