my check engine light came on 2 days ago took it the shop the next was told it was the EGR valve, took it to another shop, was told after a diagnostic that I have gasoline leaking into my radiator. The mechanic that work on my truck stated he has done this for over 30 yrs and has never seen anything like this before, but once, for the same make & model as mine. He stated that this should not happen, and does not know how this could happen, since my truck shows no other problems. Was told it was a safety issue and maybe covered under warranty due to a defect in the car itself. How could something like this happen?
