NHTSA Complaint #11424874 — 2014 GMC ACADIA

While traveling approximately 75mph the Service Traction Control light came on followed closely by the Low Oil Pressure Stop Engine Immediately light. We attempted to travel to a more safe area along the interstate. Within seconds the engine immediately shut off causing the loss of power steering and power brakes. The steering wheel locked in place causing the total loss of steering control. We were able to bring the vehicle to a safe stop, I would attribute this success to my being a Defensive Driver Instructor and Transportation Safety Professional. The risk associated with the issues we were faced with could have easily ended in tragedy especially at this speed (75 mph, 80 mph zone) The diagnosis of the vehicle was inconclusive due to the number of codes that were shown. The vehicle was no longer functional and had to be replaced. No documentation, other than the bill for towing is available. Diagnosis was done at no charge.
