Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“I own a 2016 GMC 3500 Diesel that had a serious mechanical breakdown while traveling on the freeway. The truck lost all motive power and needed to coast across 4 freeway lanes. Once towed to a local GMC Dealer, they diagnosed the problem as the Bosch CP4 fuel pump internally came apart while driving. I have to have this vehicle working so I got it repaired at a cost of $16,145. This is a known issue and losing all power while at highway speeds could have caused a serious incident. Please address this issue before someone dies.”

NHTSA complaint #11532754, filed 2023-07

“This is a 2016 GMC 3500 Denali truck with 70,000 miles on it. The Bosch fuel pump threw metal shavings into the fuel system. This is a known issue with GMC trucks with a Bosch CP4 fuel pump for 2011-2016. The engine suddenly quits running leaving the driver without power steering or power brakes. It happened to me when pulling a 14,000-pound 5th-wheel RV. Fortunately, I was on an interstate outside of Grand Junction CO and the road was flat. If I had been in the mountains going downhill and the engine quit I'd likely caused an accident perhaps fatal. GMC quoted me $16,000 to repair. …”
