H3 in the shop AGAIN

[Av1ator]

As you are driving along it gives you a Traction Control Failed Warning and Power Reduced Warning. No Power can hardly go up a hill! Pull over turn it off, let it sit a minute and the warnings go away, the check engine light stays on until it is parked for sometime, then goes off. IT maybe OK for the rest of the day or may fail again in 10 miles.

The dealer says it is something to do with the acclerator and no parts are available. So GM pays for me to ride in a rental for who knows how many weeks.

I am at 45,000 miles on my 06, GM has given me a 100,000 warrenty on the engine, what do you think the chances are I can get the rest of the drivetrain??
