Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Exhaust manifold bolts are breaking off for no apparent reason. I have four broken already and an exhaust leak developing. This appears to be a defect in manufacturing. I have a friend with two of the same trucks that the same thing has happened to. There are numerous complaints posted on the web. I have had many vehicles over the years and worked them hard but have never seen a broken exhaust manifold bolt on any of them. This can be a dangerous situation as having exhaust leaks under hood could cause a fire. …”
