I love my Yukon XL. I have driven it to Alaska, cross country, all over. I have more than 190,000 miles on it.
BUT...
About two years ago, it started stalling-while on the road, at 65+ mph. I replaced the fuel pump-three times. It still stalled-only when on a long trip, having driven 6+ hours at highway speeds. Then I was told the pump between the two gas tanks needed to be replaced-done, to the tune of $2,400+. It still stalls. On local trips, all is well. Even a few hundred miles don't bring on the problem. But, last week, after the $2,400 repair, I headed to Tulsa. It ran fine. I drove around Tulsa for a few days. It ran fine. I headed back, via Raton, NM. About 300+ miles along the way, 50 or so miles short of Raton, it stalled. After it sits for a few minutes, it starts and runs fine for awhile. Eventually, I could only drive a mile or so between stalls. Enter AAA towing.
A step-son did some searching and found a blog suggesting the crankshaft position sensor, or the camshaft position sensor, might be the problem. The repair shop in Raton replaced the crankshaft sensor but could not locate the other one. I drove on, only to have the vehicle stall at Santa Fe. After spending the night, the local GMC dealer looked at it and found nothing. They also could not replace the camshaft sensor because it is unavailable in the GM parts network. I got one at NAPA and the dealer installed it. I headed to Arizona, but it stalled before I got there. Since I wasn't far from my destination, I kept on going, driving in the right lane and pulling over whenever it stalled. After leaving I-40, my speed was reduced to between 50-60 mph. It didn't stall for the last 60 miles. This is a big, costly problem and I would appreciate anyone with a suggestion as to how to deal with it.
