“I was driving on i35 at the speed limit when I heard a loud pop overhead. I was not sure what it was, wondered if it was gun fire. A few days later when I got in my vehicle, and the sun was out, I was closing the sunroof cover when I noticed that the glass was shattered, pieces of glass were everwhere and began falling with the movement of the cover. It is extremely dangerous as shreds of glass are everywhere.”
NHTSA complaint #11390524, filed 2021-01, 90,000 miles“After just parking the vehicle but before getting out - the drivers headrest exploded and pushed my head toward the steering wheel. When driving the vehicle home the message center said problem with the driver front airbag and the passenger front airbag and the warning light was on. The next day I drove to the dealer and they pushed the headrest back together but could not get the message removed and said it would need diagnostics. I drove away with the messages still coming on intending to make an appointment for diagnostics. …”
NHTSA complaint #10855155, filed 2016-04, 105,000 miles“Drove to a parking lot turn the car off, the steering wheel did not lock, and when trying to start the car nothing happened. The car was dead other than door locks and a few things like the radio. Found out on YouTube how to start the car. After starting the car the steering wheel had a clicking noise as it turned right to left and it would occasionally lock. After turning the wheel left and right a couple of times I was able to steer the car. We drove the car 2 miles to our home and along the way while turning the steering wheel would lock. …”
NHTSA complaint #11506202, filed 2023-02“This is a health and safety issue regarding my car. There is mold build up in the AC system, which is a health and safety and environmental issue, this car is dangerous to the health if my family, especially to my son with asthma. Mold causes many health problems, and this car should not be driven. There is a class action lawsuit against the manufacturer but the dealer said they cant do anything about it right now to fix the problem. So our health is at risk everytime we get into the car. I can't afford to buy a new car. …”
NHTSA complaint #11328074, filed 2020-06“The seats on both the passenger and driver size has split at the seams. They began to appear in 2012. The battery failed and the car would not start. Periodically the car starts up slow. The car bucks in a hard motion when trying to accelerate. The car makes a grinding noise, with a dragging feeling, while driving. Mechanics cannot figure out what or where the sound and feeling is coming from.”
