NHTSA complaint #11354771, filed 2020-09, 218,000 miles

“I was driving down a highway road when my vehicle abruptly lost power, I received a warning from my dashboard saying fuel filter needs replacing and subsequently lost engine power which resulted in no power steering and no brakes. I was able to keep the vehicle under control and got it to the side of the road before it became dead. After getting the vehicle towed to a garage it was determined that the cp4 fuel injection pump had failed resulting in fuel being starved from the engine and the result was the engine shutting off. …”
