Did you ever find out why your engine light came on? I have a 2005 300C Hemi with the same problem! Light comes on & off when you have 3/4 tank or full tank of gas. Goes out -- gas cap on tight... 02 sensors ok - visual ok -- system ok --- everything else ok except car smells hot inside -- like overheating (but is not) fluid levels are 100%
oil levels 100%, h20 okay-- nuts and bolts tightened down, air cleaner new--
have not taken it to the dealer yet---
have heard they just give you the run around and ask for big $$ for diagnosis
this car is babied all the way!!

any help would be great.

thanks
