Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Traveling at a normal rate and speed on a 5-lane highway. Vehicle loss power, engine lights activated. After maneuvering the vehicle off the highway, I shut the engine off. No signs of smoke or any leaks from engine (topside or underneath). I attempted to restart the vehicle and upon doing so the engine turned over and ran at a rough idle, clearly not on all 8 cylinders. I shut the engine off again. From that point on it was towed. The Chevrolet dealership (after 8 days and 449 miles later) then told me they could not find a problem. …”
