Example complaints

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

“On november 5, 2015, I took my 2003 Tahoe in due to the fact that an exhaust manifold bolt had sheared off during the normal course of driving. I bought my Tahoe new and have always had it service at the mccarthy-morris Chevrolet dealership on overland park, ks. I realize that over time parts on a vehicle will break and at 118,000 miles I should expect to incur maintenance expenses. However, based on my research GM used a substandard bolt and this issue impacts millions of GM v8 motors. …”

NHTSA complaint #10789277, filed 2015-11, 118,000 miles

“Yesterday was driving home from work and came to a round about, slowed down and vehicle died (alternator gauge went below 14, oil pressure dropped below 40, and battery light came on). I lost all steering and brake pedal was stiff. Now vehicle continuously idles rough and will stall out if not on the throttle, idles 500 and lower. I have replaced mass air flow sensor, air filter, plugs, wires, o2 sensors, fuel filter, evap canister, alternator, and had throttle body cleaned. See there are many complaints filed of the same issues and wondering if anyone at GM has found a solution. …”
