Thanks guys. Been a while since I have been on the forum, got bored with all the negative "IT's gona blow" stuff. Then I got this recall and wham! When they installed the update the dealership toasted the ECM, it took 5 days to get a new one and during that time they left me high and dry with no wheels. After the update the truck has less power, gets less mileage on a tank but worse is the regen. Seems that every time I look at the CTS it's in regen. In 1 three hours highway trip it regened 4 times and that was while pulling my trailer. Prior to the update it would not have regened at all as the truck ran hot enough not to require it. This sucks, just wish I could get to GDE. Hopefully soon.
