While driving, car will have no acceleration and be stuck at 40 mph randomly. If I pull over, turn car off, wait a few, then it may work. It seems that it wont downshift while this happens. Happens more when travelling up very little inclines. Been is shop many times. Could this be a filter repair?

Dealer charged me $110 diagnostic fee to tell me that pcm needed to be replaced at a tune of $900 + labor. I did some research and saw where pcm were recalled in 2006-2007. I called the manufacturer and was told,based on my vin# that my 2007 commander was not included even though im experiencing the same exact problems. My personal mechanic advised me to pickup my vehicle up immediately from the local dealer. Does any one know about a pcm software upgrade?

When I turn on the heater the temp gage shows that the engine gets even hotter! What could cause this? I don't see a rad leak.
