Exhaust leaks caused by calapsed exhaust manifold pipes on 34 IC units with PSI engines. they are wrapped with aluminium covering with insulation. This in turn makes high heat tempuraters that split and burn up and disfigure pipes. Which can cause a fire if any oil leakage or fuel occurs. It also has been snapping exhaust manifold bolts away from manifdolds.

School buses. We have a fleet of these and the condition is happening repeatedly and to almost every bus with this PSI brand 8.8L gasoline engine. The engine exhaust downpipes melt from excessive heat and/or fuel. The pipes then crack and produce an exhaust leak near the body firewall. Potential for exhaust and flame to escape from the pipe.
No unusual pattern of severe incidents in the complaint record.
Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.
Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
