Complaints on fileComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Fire reported

The motor experienced a catastrophic failure causing the rod to blow through the top of the engine, cutting a fuel line and causing a fire. It was later determined and passed to me via unofficial sources that this was due to a manufacturing defect where the incorrect camshaft bearings were used on specific pistons. Via online and first account conversations, it seems this has happened at least 12 other times. Those vehicles which can be found online were complete losses. Via second hand conversations, Porsche technicians said this was the first instance where the fire didn't consume the entire vehicle so they could RCA the problem.
