Sierra 3500

  • miles
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.
