The contact owns a 2016 Ford F-150. The contact stated that while driving at approximately 30 MPH, the vehicle hesitated to maintain acceleration while the accelerator pedal was depressed, which caused the vehicle to jerk forward into the rear bumper of another vehicle in traffic. The front bumper struck the rear bumper of the other vehicle. A warning message reading "Cannot Exceed 80 MPH" and an additional unknown warning message were displayed. The air bags did not deploy. No injuries were reported. A police report was not filed. The vehicle was taken to an independent mechanic, where the front bumper was replaced at the contact's expense. The vehicle was later repaired under NHTSA Campaign Number: 26V237000 (Powertrain); however, the repair failed to prevent the failure from recurring. The vehicle was taken back to the same dealer, where it was determined that the vehicle needed further diagnostic testing for a possible transmission repair. The vehicle was not repaired due to cost and remained at the dealer. The manufacturer was notified of the failure. The failure mileage was approximately 88,000.
