I have a 05 gt and notice the traction control wasnt working. I pushed the the button and still no trac control or no light on the cluster, i then notice no service vehicle soon, brake, ABS,oil,engine,security light,cruise,battery,seatbelt and second TC light not working at all. i had a engine replaced (at135k)about 6months ago and took it back to see if something was left unconnected but nothing. i also notice that i have to use 2 keys one to open the doors and the other to start the engine. Any suggestions would help.
