Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Check engine light came on throwing p203b code, which is the reductant level sensor code. This seems to have been an issue already in these vehicles dating back to 2011 when it started. I found a service bulletin #14652a regarding the replacement of such sensor but the dates on the vehicles only state 2011-2012. I want to see if there is a newer bulletin released which covers the later years with the same problem.”
NHTSA complaint #11363540, filed 2020-10, 79,500 miles“I am on a cross country trip and the vehicles engine light came on, I pulled into a chevy dealer for service. Chevy dealer claims the part needed for repair called an ECM module, (I.e. Computer) is not available and it is not being produced because of a defect in design. The vehicle has been with a chevy dealer for 10 days. I am 1100 miles from home and general motors has refused to give me a loaner to drive back to kansas city. In talking with the diesel technicians at two of the dealers, they claim this is a widespread problem that GM is trying to hide.”
NHTSA complaint #11089830, filed 2018-04, 34,500 miles“My 2016 Chevy at a stop light started jerking and then just shut off and wouldn’t start again. I had to have it towed and was told at the repair shop that it was the CP4 fuel pump that went. Of course I had them do all the repairs and they found metal shavings all through out the fuel system. I was without my truck for weeks and had to pay ridiculous cost of almost $13,000. With how often this is happening this should all be reimbursed to me and GM needs to step up and take care of it along with NHTSA.”
NHTSA complaint #11549209, filed 2023-10“The 6.6L V8 LML turbodiesel Duramax engine Bosch CP4 fuel pump failed. U.S. diesel fuel does not provide adequate lubrication for the CP4 fuel pump. The lack of lubrication led to internal fuel pump damage and resulted in metal shavings that damaged the pump, the fuel system, and the GM Duramax engine as well. There was no warning lamps, messages or other symptoms of the problem prior to the failure.”
NHTSA complaint #11558992, filed 2023-12“Transmission needed rebuild at 108000 miles. Lifter failure in engine which damaged camshaft at 120000 miles. Each costing thousands in dollars of repairs probably close to $10000.”
