I have a intermittant dynamic drive inactive fault. The fault only occurs after the air temperature gets above 73 degrees. I have no fault in the AM when the car has sat overnight, but if the temp is above 73F, after I drive it for a while and the engine heats up or the car sits in a hot parking lot for a while, the fault occurs and stays on after the car is started. And it will remain on for the remainder of the day, no matter the temperature. The next morning it will be gone and may or may not return. I have had it to a dealer and a non-dealer repair center. The dealer insists that the Dynamic drive controller needs replaced $700US, and the Non-dealer shop insists that the front stabilizer bar needs replaced $1800US. What could cause the intermittant fault signal and how do I repair it?

after car sits for many hours, unlocked (like in garage), the interior lights do not come on when door is opened. They only come on after car is started or you hit the open locks on the key FOB. And this also starts the interior CD changer to reload all the CD's...Anyone have any ideas?
