Been a pile since the day I bought it.
My vehicle is affected by something GM acknowledges is a problem but refuses to fix it. Actually they tell me there is no fix for it. When the temperature outside gets about about 90 degrees the Yukon loses all throttle response and power. Literally runs like a pile of junk. Almost to the point where it’s unsafe to enter traffic because the truck doesn’t move. Starts shifting really hard but no check engine light ever comes on. When the temps are cool, it runs and shifts like a champ. The problem is I live in Tucson, AZ where the temps are above 90 for probably half the year. I will NEVER buy a Yukon again. GM should take this pile back and give me my money back. Yea right.
