Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“After buying the vehicle, the former owner said that the pdm would overheat and the engine would just fail and there would be no ability to steer or to brake. He said the only way to fix the problem was to move the pdm away from the fuel injection pump. He told me that I would have to wait an hour before the vehicle would be able to be restarted. He said the problem is that the pdm gets too hot which causes it to shut the engine down, which only stands to reason. The pdm is an electrical component in a small box attached to a piece of metal that reaches temperatures in excess of 300 degrees. …”
