According to the dealer, my ignition housing needs to be replaced and that is what is causing the intermittent starting problems. They quoted about $420 to repair that. They also said I have error code P0A81 and that they will not cover the necessary replacement of the cooling fans under warranty. After reading a thread on this issue, I decided to contact another dealership about the cooling fans. I hear this particular delaership replaced them under warranty for someone else, so I am hoping to hear back from them with good news. In the meantime, does anyone think the replacement of the ignition housing is a DIY project worth attempting myself?
