‼️ “What Should Have Been an Exciting Truck Purchase Has Turned Into a Nightmare—Including a Dangerous Breakdown in the Middle of an Intersection.”⚠️ Long post but worth the read! June 30th I purchase Turned Into a Nightmare—Including a Dangerous Breakdown in the Middle of an Intersection.”⚠️ Long post but worth the read! June 30th I purchased my almost new GMC Yukon Denali. For the first 2 months we had no issues and truck drove fine. That changed shortly after. 9/4/26 my a/c randomly stopped working and was blasting hot air. Called and left message for dealership as it was late in the evening. 9/5/26 driving home from my sons football game in the middle of the road my truck jerked a few times as if it was stuttering. Then stopped. About 7 minutes down the road we are stopped at a red light. When the light turned green we went to turn and my car started to go, but very very slowly then just stopped in the middle of the intersection. A busy intersection at that. Lights on the dashboard lit up with codes, couldn’t do anything. My truck sat in the middle of the intersection for several minutes with hazard lights on, honking cars, and a terrified kid. Eventually we were able to start the truck about 10 minutes later and were able to pull the truck to the side of the intersection. We called the dealership and due to it being late in the day nobody from service was there and no service manager or GM were in to speak to. We explained the situation to the sales manager, expressed the frustration, serious concerns, and panic we experienced. We were asked if the truck drove to drop it at the dealership to be looked at. Came home and sent an email to all of the managers and GM at the dealership. 9/7/26 dropped truck off at dealership to be looked at the following day being that Monday the 7th was a holiday. In between the time that we dropped the truck off and the dealership had the truck there was very little communication. It was us contacting the dealership for information and updates. 9/23/26 received a call late in the evening that my truck would be ready for pick up tomorrow morning. Dealership replaced a fuel pressure performance pump. 9/24/26 Dropped my kids at school and drove to the dealership to pick the truck up. I left the dealership and went home to work. Later left to pick my kids up from school and as I’m driving the check engine light comes on. This is only a few hours after I picked the truck up and probably only drove about 10 miles. I was told to drop the truck back off. Meanwhile this is after the dealership had the truck for almost 2-1/2 weeks. 9/25/26 Leave to drop truck off at dealership. I back out of the driveway and all my cameras are blacked out. I checked all of the different camera angles and all were black. Thought that was very strange so about 30 seconds down the road I pulled over to the side of the road, turned the truck off, opened the door and then turned the truck back on. When I turned back on the cameras were all still showing black. I continue to drive about 1 minute down the road and come to a red light. When the light turn a green I try to go and my truck shuts down and off again. Not only am I at another intersection with no way of moving but this is all within 24 hours of having my truck back after it was supposedly “fixed”. The noise of the truck sounded like an airplane. When I opened my truck door it was the most horrible burnt rubber smell. Had to call a tow truck to come pick up my truck and take it to the dealership. 9/28/26 Contacted General Motors, explained the situation and frustration with my truck and a case was opened. During week of 10/05/26 an engineer from GM looked at my truck and gave suggestions to the dealership. 10/14/26 Spoke with the service director and was asked to explain again what happened the 2nd time the truck broke down. Service director followed up with some questions back to me. Asking what the weather outside, how fast I was going. I was told that the dealership had their best 3 technicians putting their heads together trying to figure it out. More
