What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
It is pretty clear to me that they know how to fix the issue, but they are using stall tactics to avoid incuring the cost they are legally bound to spend. My particular make/model/year was supposed to prioritized and completed by march 2018.
Air bag light is on and it needed service cruise control malfunction, break sensor
While driving 60 mph, the rpms increased and decreased, the headlights flashed intermittenly, and that the entire instrument cluster with different warning sensors illuminated intermittently. The vehicle was driven home. The vehicle was not diagnosed or repaired.
In june 2017 a service air bag light came on. I called the dealer (williams chevrolet) in elkton maryland and they told me that I would have to pay for the fix. I called chevrolet customer service and was told the same thing. I was told by both parties the recall didn't mean anything that I had to pay for the fix.
Consumer writes in regards to vehicle power door locks and tailgate power lock actuator mechanism failure. The consumer stated the power door locks and tailgate power lock, would no lock or unlock.
While driving approximately 30 mph, the check engine warning light illuminated and the vehicle stalled. The vehicle was taken to the dealer multiple times over a span of three years where it was diagnosed that the throttle position sensor and the program sensor kit needed to replaced.
Excessive oil consumption. It the 5.3l with active fuel management system. Gm knowns there is a problem and the only fix is to replace the rings and pistons or replace the entire engine at the owners expense, 5,000.00 - 8,000.00. Since it's it's a design flaw, I feel they should fix it at no cost.
Galvanic corrosion between dissimilar metal (aluminum and steel) components in the manufacturer's installed bed cover system is causing the latching mechanisms for the bed cover to disintegrate and cease to function as designed.
