Oh wow, sorry to hear that. Did you do anything specific to get the computers communicating again or was it random?

Just had similar issue on a 2006. Ended up being a bad dash cluster. Really had my doubts but it was a inexpensive fix thankfully.

Ouch, that does not sound cheap! But probably super effective, especially compared to the dealership that scratched their heads over my issue for almost 4 weeks

Could it be a vacuum leak causing the service traction control ? All computers and sensors communicating and working properly
