The vehicle had previously been serviced under NHTSA Campaign Numbers: 19V761000 (Service Brakes, Hydraulic, Service Brakes, Electronic Stability Control) and 19V645000 (Service Brakes, Hydraulic) at the dealer; however, the failure recurred after the recalls were repaired with a stiff brake pedal and increased braking effort while driving. The contact stated that while his wife was driving at an undisclosed speed, the vehicle went over a curve and the front passenger's side crashed into a tree, then came to a complete stop in a ditch. There were no air bags deployed. The contact's wife sustained neck and back injuries but did not receive medical attention. The vehicle was towed to Coughlin Hyundai (2300 Hebron Rd, Heath, OH 43056) where it remained and was not repaired. The vehicle was not deemed totaled by the insurance company. The manufacturer was made aware of the failure and a case was opened. Prior to the failure, the contact was receiving notifications from OnStar that NHTSA Campaign Number: 19V761000 (Service Brakes, Hydraulic, Service Brakes, Electronic Stability Control) was unrepaired. The failure mileage was 111,572.
