Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“While driving on I-95 in my 1994 Chevrolet C2500 with the 6.5 l naturally aspirated diesel, my truck suddenly stalled and I lost all my engine powered components (power steering, brakes, etc.) I pushed on the brake pedal very hard but was barely slowing down. I finally got the truck slowed down enough to get off on the shoulder of the freeway. I then had to sit there for 30 minutes to allow the pump mounted driver to cool down before I could turn around and garage my vehicle. It happened several (5-10) times over the course of a 30 mile trip. …”
