Our 2015 yukon xl denali has been in for repair service for 41 days since purchased new 3/23/15. The car has stalled while in motion with my wife and three daughters in the vehicle twice and been unresponsive to throttle input 3 additional times. The stall occurred once while turning left across traffic and another time while turning right and merging with traffic! The problem is intermittent and gmc has never been able to replicate it. They have given us the shoulder shrug, "I don't know what to tell you, we can't replicate it" line, so here are your keys. No warning indicators, no signs it may happen, and no way to pull up the issue with their diagnostics...huge safety concern and each time they have handed us the keys back after 7 days (their standard allotted time to have a loaner out) without any proactive escalation to find root cause or concern for my family's safety. The last time we took it in, they had it for 8 days and could not replicate the issue. We signed our service paperwork and I escalated to the service manager before leaving. After telling him we would be pursuing buyback, he miraculously had an idea it may be related to a wiring harness issue. This was based off his experience with a sierra pickup (5.3l, not our 6.2l) that had similar behavior. We left the vehicle and, wouldn't you know it, they replaced a wire and "have reasonable confidence" it resolved the issue. Two weeks later, it's back in the shop for key fob not detected (after already driving). Truck is in gear and you cannot move...another huge safety concern. It's a dud. We have also had to have all 8 injectors replaced due to rough idling and the steering gear replaced from faulty manufacturing that creates a clicking while turning the wheel, the car is at the dealer and we will not be taking it back. We are going through the offical buy-back process with gmc.

When the car is at idle in drive it becomes very rough (fluctuates up and down). This happens on and off and I have no check engine light on. Sometimes the car even feels like it is going to stall out. I have had it into the dealer and they admitted they feel it as well. They tried adjusting the motor mounts and that did not do it. After having in the dealer for several days they called me and said they can't find the issue. They told me they went into another 2015 gmc yukon sle and started feeling the same issue. It was stated to me I might have to wait for more complaints on the vehicle to get to the root of the issue. It continues to idle roughly and I want to get this resolved.
