Anyone have problems with check engine light, have had front air shutters replaced 10 days, worked for a while, about 800 miles, engine light again, no related codes, cleared, back to dealer , fans running wide open in 25 degree weather, temp gage not even registering. 9days in shop, short in wiring harness probably be several more days, they are going to do an "overlay" bypass the short by jumping wire around it. 13,700 miles on it probably another few days in shop yet. Other things, raido quits sometimes, works next day. air bag service needed warning several times 6 or so, also passenger bag warning, couple times. Map light came on while driving drivers side.
