The contact owns a 2023 Chevrolet Traverse. The contact stated that while driving at an undisclosed speed, there was an abnormally loud sound coming from underneath the vehicle while depressing the accelerator pedal to accelerate. No warning light was illuminated. The vehicle was taken to a local independent mechanic, where it was diagnosed with a hole in the exhaust system causing the acceleration failure. The vehicle was repaired out of pocket.
