I write to express my concern over an issue with my 2015 GMC Yukon that has also impacted other community members. In April, my Yukon, with just over 70k miles, broke down as I was turning from Rte 14 in Pembroke, MA onto Rte 53. At the time, I had my 3 & 5 year old children in the car with me. I could not get my vehicle to restart & had it towed to a local mechanic. After our local mechanic could not diagnose the problem, on 4/25/23, I had the vehicle towed to Marty-??s GMC in Kingston, MA, where it was purchased. I had to call Marty-??s regularly to check in on my vehicle before it was finally inspected. After 2 weeks, I was told that the valve spring needed to be replaced & the fluids flushed. I approved those repairs totaling $1600. After a couple of days, I received a phone call that there are issues with the lifters & brakes which would add another week of repairs & bring the costs up to $5,500. After another week, I received a call that there was more work to be done increasing the total cost of repairs by an additional $1,000. When I finally picked the car up, I was notified that the estimates I received were miscalculations & my repair costs totaled $7,512.23. Since this ordeal, I have talked to several GMC owners with cars of a similar age & low mileage. These owners have experienced the exact same issues. Throughout my conversations, I learned there is a service bulletin out on the issue with the lifters, but no recall. The lifter issue is a serious safety hazard. I have made multiple attempts to reach someone at GM-??s corporate office to try & initiate a formal recall for the lifters. No one has been able to tell me how a recall gets issued. This whole ordeal has been a massive burden, both emotionally & financially for my family. It feels as though my young children & I were put in harm-??s way for a known GMC issue that could have been avoided.

The engine turns off when driving. This has happened at least 50 in the 2 years I've owned the vehicle. It has been serviced at Garland Shelton GMC in Temple, TX. The issue is not fixed. The battery and the negative cable have been replaced. When the engine dies none of the electrical works until I open the hood and wiggle the negative battery cable.

I just got my vehicle into the dealership because it's 115 degrees outside and the air conditioning stopped working. I am 8 hours away from home traveling with 6 children so I begged them to squeeze me in the same day for repair and they did. The dealership is saying it's a Crack in the air conditioning condenser and it's $1,600 to repair. This is unbelievable. 80,000 miles on it. This should be a safety concern. Sitting in stop and go traffic for hours in 115 degrees is unacceptable. GM needs to fix the problem and do their customers right.

Pulling out onto busy road the vehicle make a loud noise and then failed to accelerate and lost power. It was three seconds before the vehicle then slowly accelerated. This continued to happen while driving. The dealer then advised that GM was aware of this issue and has not issued a recall to date. This loss of power was dangerous.

When sitting at a light, or stop sign vehicle acts as if it wants to cut off, check engine light is flashing, when I'm driving vehicle the check engine light stays lit. I did a scan of the vehicle and the code I got was P0303 which is for a cylinder 3 misfire. I have changed out the spark plugs and wires, also the ignition coil. I changed out the fuel injector for cylinder 3 and also the fuel pump actuator. Its still shaking, don't know what the problem is but I hope you guys can come up with what I need to do next. I've had to spend money out of pocket for this because its not under warranty.

My Yukon has a leaking radiator which is a known defect not just in Yukon, but also in Tahoe, Silverado, Suburban and other vehicles. GM refuses to cover the repair for all trucks, only certain ones. I'm not sure what the criteria they are using is...but it is the same defect affecting all of the vehicles.

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.
