It could be anything really from fuel delivery to spark-weak fuel pump,bad fuel,sensors etc its a crap shoot unless you have a good mechanic and it might be something simple
This issue is the largest discussion topic on this forum...... check for "cant unlock maps"
Bamfrank knows how to fix it but for most of us it was warranty replacement or do without
Go ahead and try but the 09's had much smaller rotor's and calipers and the wheel would not fit my 13 Crew off of a 09 RT and both had factory 19"rims and I used 17" snows on both also....good luck
I have the 7-160000 gold warranty and never had the "inspection" however I did have it checked when they did the recall recently because I'm almost at the 160 mark.
They said it was good then my bluetooth failed LOL but they couldnt have known that and it was covered anyway.
Hope that helps
