Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I been having a problem with the exhaust manifold bolts breaking off. I spent a ton of money replacing o2 sensors over the last 4 years. I've just currently found out that the o2 sensors were not bad, it was actually the exhaust header bolts breaking allowing my emission system to malfunction. I've had 3 bolts replaced 2 months ago at a tidy cost of $1000.00. One week ago I was driving down the road and smelled exhaust fumes in my truck cab. I took my truck to my mechanic and he found 3 more bolts on the right side of the engine broken off. …”

NHTSA complaint #10439301, filed 2011-12, 38,255 miles“While driving 60 MPH vehicle stalled. The consumer tried to restart it, but was unable to do so. The consumer had the vehicle towed to the dealer for inspection. The mechanic replaced the electric ejection pump, however the problem recurred. No matter what speed the vehicle was going, the engine would die as the key was turned off. Sometimes the vehicle restarted immediately, but sometimes it wouldn't restart until it was worked with. The electric injection pump was replaced for a third time. …”
