On the way home tonight doing highway speeds my 2016 GMC Yukon SLT engine light flashed about a dozen times and then went off. Truck showed no signs of misfiring and ran completely normal.
However I noticed it no longer switched down to 4 cylinder at slower speeds like normal. Truck only has 91,000 miles and has been trouble free so far.
Any advice/help appreciated.
