Engine shuts off, steering assist disappears and steering wheel is jerked out of my hand, stabilitrak warnings on dash, HVAC screen goes blank, chimes start going off. This occurred as I was pulling into a parking lot and I almost hit another car. The vehicle was moving at no more than 10mph.

2015 GMC Yukon - replaced the bad condenser! very costly, part was on backorder for 2 months so obviously there are a large amount of others having the same issues. This is considered safety issues due to the heat in the South and we paid $65,000 for a vehicle which 2 years later now has a bad condenser - an additional $1,000. I'm done with GMC. I feel like we have been treated poorly and this part should be recalled immediately. You are a billion dollar industry, if you want to keep people coming back you make it right with your customers. I want to be reimbursed for my entire bill I'm about to pay. I am so disappointed, I have always always been a GMC/Chevrolet person but this has truly made me sick to know that my family forked out $1,000 for your mistake! come on it's a $65,000 vehicle...very very very angry. Please feel free to contact me regarding our bill and how you will attempt to provide amazing customer service to make this right.

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.

Our vehicle has a significant vibration in V4 mode when traveling between 45-65 mph and above. The vibration is also accompanied by increased cabin pressure. These issues are causing headaches, nausea, dizziness, and are further exacerbating my wife's multiple sclerosis. We also have a popping sound coming from the rear of the vehicle's suspension when turning that makes us feel unsafe. The vibration started right after we took delivery of the car and has only gotten worse. We bought the car in April 2015 and the issue continues unfixed to this day. The popping noise started about 3-4 weeks ago and it sounds like a suspension component. Our ac recirculating feature also does not work and it allows harmful exhaust smoke in.

I am writing to notify you about a problem with the transmission in 2015 GMC Yukon XL. GM is aware of a problem. They issued an internal notice to dealers in February 2016. However, they have not notified to owners in the form of a recall. On several occasions, my vehicle jumped forward, while driving in the city, when it was stopped, in drive, with brake engaged. I reported transmission problems to my local dealer but they repeatedly ignored my concerns. They kept giving excuses that didn't make sense. I finally pressed on, refused to take my vehicle back and reported the problem to several executives. The problem was finally diagnosed under different conditions as stated in the first internal document in March 2016. There was a problem with the transmission. They finally replaced the transmission for "one that didn't have a problem". GM admitted there are problems with transmissions and the problem has been corrected in newer vehicles. They have yet to issue a notice to current owners that their vehicles are at risk. I owned a 2015 GMC Yukon XL but chose to sell it over safety concerns and lack of appropriate response from GM corporate. With 2 young children, I spend a lot of time around schools (like most owners of large GM vehicles). I could have injured or killed someone. I feel it is my obligation to bring this situation to your attention. If you intervene, you can help to avoid any injuries in the future. It is clear that GM will not voluntarily protect the public.

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.

I have a 2015 Yukon denali and I was driving 65 on the highway and the engine shut down completely. A warning message said engine power failure. I had 4 cars and an 18 wheeler behind me at the time. I managed to put the vehicle in neutral and coast to the side of the road onto a median. It was towed to the dealership where they started trying say it might have been bad gas. Then I was told I cracked valve and they already had one other just like this, then 1 day later after a tech level 2 and a shop forum looked at it, and a conversation with a GM pac rep, GM approved a complete engine replacement! I was shocked. I've had the same 4-wheel drive issues everyone else has. I've also had A/C problems, steer wheel popping noises, sunroof loud wind noises. My seat shifts when I drive it. The A/C seats don't cool properly, which I found out when they put me in a loaner Yukon that worked fine. The speedometer gauge also didn't work for 2 days, which I have a picture of and received a warning ticket for when I was pulled over by an officer not knowing what speed I was going. I passenger step guard doesn't always retract properly. My unit was purchase May 2014 and was one of the first 4 X 4 units that was produced and has had constant problems. GM keeps denying a buyback, then no trade assistance, then now has offered an extended warranty. This particular vehicle I have is not safe for my family to be riding in. I can't trade it in or sell it to anyone else knowing the problems it has. The dealer won't even take it because they know the problem that they are dealing with.
