2015 GMC Yukon Owner Comments

problem #6

The vehicle has leaked water in the seams of the back driver side since the initial purchase. It has been repaired nine times by two different dealerships and it still leaks. The vehicle now contains a high moisture reading and was tested by a mold specialist and determined to have mold. The vehicle is currently with the dealership.

Window appliquÉS on both sides of vehicle became loose and were flapping while driving. This was concurrent with a very noisy cabin, likened to the sound of a window being open while traveling at highway speeds. These appliques were previously replaced by dealer after incidentally being found loose. The noisy environment in cabin is very loud and distracting, causing driver and passengers to get headaches and causing driver to become distracted.

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.

Vehicle has a vibration when going between 60-70 miles per hour on highway. The vibration starts and stops over and over again. Vibration last about two seconds each time. Took vehicle to dealer they said the issue was caused by recall that GMC was trying to fix. Currently no part is available to fix vehicle. Instructed to just keep driving vehicle with the vibration until a part is issued.

When driving at highway speeds in the rain, water pools on the drivers side and passenger side door window at the bottom front of the window blocking the driver's view of either side view mirror. I went to the dealer in carson city nv, and service director stated they had this problem with trucks since 2007 and there has been no solution.

My wife and I were driving on the parkway at about 65mph when we heard what sounded like a gunshot in the vehicle. We pulled over to the side of the road only to find out that the sunroof literally exploded on the car. All of the glass that was left was bowed upward which would indicate that the sunroof explode outward and nothing hit the roof of the car. When we brought the car to GMC they claimed that something must have hit the sunroof to make it explode which I know did not happen. Needless to say, GMC is unwilling to cover the damages to the car under the warranty.
