Traction active is kicking in........why? This is a very dangerous problem if you pull out in traffic and your car won't move and I am wondering what is causing this to happen.

You could have a dirty or damaged tone wheel on one or more wheels
you did not mention if any abs or traction lights were on in the dash
if none are on then i would check and clean the tone wheels on the rear[2WD] or all 4 [4WD] if that dont do it a trip to the dealer would be a good idea

Ok, traction control is operated by the abs unit (advanced braking system). do you have any dash indicating lights on? if you pull power to the abs system your problem is fixed. but you do need to fix this it is dangerous. The cause will be most likely in your engine code you pull from the cars computer, autozone and checkers pulls codes for free.
