I purchased a 2016 Yukon Denali in Jan. 2016. It will set in the carport for several days sometime before it is driven. When it sets there for 48 + hours and I drive it, it will back out of the driveway ok, but when I try to accelerate it will pause for 1 -2 seconds, then will pickup and run properly. Runs great until I let it set for the 48+ hours. The first time I called a service manager about this, he said GM had a fix already, but the would have to go into the trans. and replace a “plate”. I told him I would drive it like it is for a while, (my mistake)!
I’ve decided that’s too much to spend on a vehicle with a faulty trans., called him again, left it with them 5 days. “can’t fix it, can’t get it to show the problem” Sent it home, problem still there!! Anyone else having this problem, if so did you get it fixed?
