2015 Tahoe LTZ that has steering assist warning, brake assist warning and stabilization warnings continually when driving. Brakes grabbed going about 30 miles per hour down hill in snow causing truck to lock up and skid sideways briefly. Wife was driving on the freeway when steering assist warning came on and caused power steering to deteriorate so it was extremely hard to steer going 65 MPH. Dealer fixed same issue due to short to ground on wake up signal for multiple modules back in Sept 2016. Problem persists. Went to dealer over the weekend but they "could not duplicate the problem" but saw the history codes noting all of the above. Reset the computer and when we drove off the lot, it took about 5 minutes for the problem to re occur. I am thinking either faulty harnesses, bad PC boards, bad microprocessors or a combo of all of these.
This should not be happening on a $70K + vehicle. Big safety issue and liability issue.
