Hi, new to this forum, searching for answers to my problem. I know this thread is a year old, but I'm having the same concern.
I have a 2014 GMC Sierra 1500 SLT crew 5.3 4x4 w/110k miles
I brought this to the dealer three weeks ago, paid $158 for the diagnosis that they couldn't duplicate the concern. Last week I was driving by the dealership during open hours while it was acting up, and went in. 25min and another $158 dollars later they tell me the brake system is compromised and I need to replace the master cylinder, vacuum pump, abs control module, all brake lines and hose, and all four calipers as the system has been contaminated. all this at the great low price of $3,800
Oh, and my a/c isn't working again, I've replaced the condenser 4 times already, only two under warrenty
Anyone have this ABS activating while trying to come to a stop, all the time when backing up, and paid for the repair out of pocket? What was the cost, and what did you replace?
any advice would be great
