Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Blower motor for the HVAC started all by its self and ran full blast. The control panel had no effect on the system . I could not control or shut off the blower. Even when the truck was parked, in park and shut down and the keys removed the blower continued to run at full blast. Had to disconnect the battery. Later after having to drive the truck to work I followed the fuse schematic and removed the green I believe fuse breaker from the under hood fuse box. I have left this fuse removed so the battery doesn't run down.”
NHTSA complaint #10906990, filed 2016-09, 97,000 miles“Upon starting my truck, the oil pressure gauge immediately goes to 80 with no acceleration. At this point, there is no noise or other lights coming on to warn of other problems. This problem started a few days ago. When truck is in motion the oil pressure gauge continues to stay on 80. I know the 2006 chevy 2500 heavy duty 4x4 have had recalls on different things, but need to see if this is a problem for other chevy trucks as well. I have read several recalls about these trucks and a lot of them we have never been notified to take it to a dealer to be checked. …”
