The contact owns a 2014 Chevrolet Equinox. The contact stated that as his daughter was slowing down to exit a highway, she was rear-ended at a high rate of speed by another vehicle. The impact from the other vehicle caused his daughter to then hit the vehicle in front of her. The air bags did not deploy upon impact. The contact's daughter was taken to the hospital by ambulance; however, due to a long wait, she was left untreated. She was later treated by her primary care doctor who performed X-rays for the soreness in her left shoulder, the middle of her chest, and right hip; she was given medication to treat the soreness in those areas. A police report was filed. The whereabouts of the other drivers were unknown. The contact arrived at the scene and was able to drive the vehicle home; however, the vehicle failed to accelerate above 40 MPH. The contact called an independent body shop and an appointment was made to inspect the vehicle. The dealer nor the manufacturer had yet to be notified of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 120,000.
