What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
The air bags did not deploy upon impact. The contact sustained minor injuries and went to the hospital the next day. The police were on scene and a police report was filed. The vehicle was towed from the scene and was deemed as destroyed. A complaint was filed with the manufacturer. The failure mileage was 96,882.
There were several unknown warning lights illuminated. The vehicle was towed to an independent mechanic to be diagnosed, and the contact was informed that the failure was due to an electrical shortage in the taillight because of an accumulation of moisture inside the taillight assembly.
Reference tsb 11-10-21, the car will surge and try to move forward quickly when at low idle and slowly moving at times when the car is close to another car such as parking in a parking lot.
Multiple instances of my car accelerating while in a lower rpm such as at a stop light, drive thru window and parking lots. Especially increased instances when the air conditioning is running. This also causes the car to die completely in some cases.
Now, at 130,000, the transmission appears to have gotten even worse where it is slipping in 2nd gear. You give the car gas and it seems to just be at a stand still, then a) of a sudden, the whole car just throws itself, and any passengers in the car, forward and just shakes the entire vehicle.
The contact stated that the front driver side seat belt hesitated to unlatch intermittently. In addition, after the driver side seat belt was unlatched, it no longer latched into place. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was 169,000.
While driving 10 mph, the brake pedal was depressed but the vehicle jerked before eventually stopping. The failure recurred on numerous occasions. The vehicle was taken to a dealer, but was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was 45,000.
An electronic device known as the smart junction box has failed 3 times since new.the first two times it was replaced under the original manufacturer"s warranty. The warranty has expired and it failed again. This part is very expensive costing in excess of $500.00 plus labor charges which I must pay.
