GMC Yukon XL hesitation problems

Filed Jul 23, 2026 · TX

The vehicle has an unpredictable and random tendency to hesitate when the gas is pressed. This has been happening at some level since the vehicle was new. The dealership service department was never able to get the vehicle to do what I was concerned about, so they never helped resolve the issue. Now that it is out of warranty, the issue is getting worse. It is to the point that I believe it is unsafe for anyone but me to drive it. I have to make sure that when I turn onto a new road, that there is absolutely noone coming because I cannot depend on my vehicle to accelerate quickly enough, even at a normal rate. It may lag and take its time speeding up, or it may accelerate normally with no issues. I stopped going to the dealership for oil changes and checking the issue because they no longer give loaner vehicles and they take a minimum of three hours for an oil change. So I recently took it to my trusted mechanic. He replaced the knock sensors, which helped slightly. He could still detect issues, but was concerned it would require a whole new engine built to bypass the DFM system and repair the cams and lifters. So I nw have to drive a vehicle that needs $20,000 worth of repair, has the potential to be dangerous or leave me broken down on the side of the road. It has 106,000 miles and I still owe $12,000 on it. From my research, I understand that this is a known issue and that there are several lawsuits regarding the issue. That does not help the average person who doesn’t care about a lawsuit, but is justifying st trying to live their average life with a dependable vehicle. Please help!

My vehicle has been in 16 times since I bought it the most recent incident is for the engine which started about six months ago. It’s been in since then for other issues concurrently with this one it hesitates like it’s getting stuck in sand before it wants to go first the mechanic told me he didn’t sense it but the thermostat was stuck open so they fix that. Second time it went in they thought it was some sort of a filter and some other components I’m not sure. Again it was not fixed then my son and I were out in Minnesota freezing cold night in November and go and drive and then when again it was the drive train this time that got fixed a month ago about a week ago it starts making a noise like there’s too much snow in the tires. I get my car washed every few days but I got it washed again and that didn’t fix it so it’s in the shop again and I’m paying for a rental again. I have the Walser guard thank the Lord because it’s paid for itself about 15 times over. I’ve gotten two transmissions, an air conditioner, two sensors the arm that other people have complained about I don’t know exactly the name of it the trailer component that you plug into also blew out my seven way and I had to have my seven way wire fixed so I’m nervous about plugging that back in. My dad passed away and I spent $70,000 of my inheritance by this car. I should’ve flushed it down a toilet instead. Everybody makes fun at work that this car is literally gonna kill my kids and I because every other day it feels like we’re stuck on the side of the road.

On January 19, 2026, Recall 25V274 was performed on my vehicle, and this was not disclosed to me when I picked up the vehicle from the dealership, Courtesy Buick GMC in Louisville, KY. I only found out when I got home and read through all the service notes. I contacted the dealer on January 19 after I got home, asking for explanation and have not heard back. The Recall Remedy failed. Since the service, symptoms of hesitation, lack of propulsion and low MPG persisted. As of Feb 1, the vehicle has suffered a transmission failure and is unsafe. The dealer told me verbally everything was fine, and in the service notes from Jan 19, they noted vehicle as 'Operating as Designed and Within Spec' despite performing safety recall work."

There is a hesitation when trying to accelerate. The car will then slam forward and there is a rattling noise that the car also makes. This has almost caused accidents. I was driving in town which is where I do most of my driving.

Starting at around 1300 miles, we noticed jerking upon acceleration. We took it into the dealership at 1500 due to a check engine light. They replaced the coil in cylinder 1. Then again at 3200 miles, we took it back in for the jerking sensation. They could not replicate the problem. At 4380 miles, we took it back to the dealer for the same issue. They drove it 580 miles and found the lifter valves in bank 1 to need replacement. The repair was performed and then on Saturday 1/17/2026, the car started giving check engine lights every time we accelerated. It would jerk non stop. The car hesitates during acceleration and feels like someone is pressing on the brake as we are accelerating, causing a jerking motion. Coming from a stop, the car feels like it has a hard time accelerating, almost like it is moving against a hard force to try to come up to speed. The car is at the dealer again today for this issue. It is unsafe to drive due to the hesitation during acceleration.

I am the owner of a 2021 GMC Yukon Denali with the 6.2L V8 engine (VIN: [XXX] ). This vehicle has exhibited multiple serious issues affecting safety, drivability, and reliability. 1. Engine Noise & Oil Consumption: Since purchase, the vehicle has had a persistent loud knocking/tapping sound, especially under acceleration. The engine also consumes an excessive amount of oil between scheduled oil changes, with no visible leaks. I reported this to the dealership multiple times, but since there is no active recall or TSB, they refused to diagnose or repair the issue under warranty. I have since learned that many other 2021 Yukon Denali owners with the same 6.2L engine are experiencing similar issues and some have had repairs or engine replacements covered by GM. I have received no such support. 2. Braking Problems: The vehicle has ongoing brake performance issues. Despite replacing the brake components multiple times, the brakes feel inconsistent and unsafe, especially during highway driving or sudden stops. There is vibration and uneven response, and the braking system does not inspire confidence. These problems have persisted despite attempts to correct them. 3. Suspension/Handling Concerns: The suspension feels unstable and loose, especially at highway speeds or when turning. The ride quality is poor, and there is noticeable sway and body roll, which creates discomfort and concern for vehicle control. 4. Fuel/Propulsion System: The engine does not always respond smoothly to throttle input. I’ve noticed occasional hesitation or surging, which may be related to the previously mentioned oil consumption or fuel delivery. Again, the dealership has been unable or unwilling to resolve these issues without charging diagnostic fees. I’ve reported these issues to my local GMC dealer on multiple occasions, but no lasting solution has been provided, and I have not been able to afford expensive diagnostic costs out of pocket—especially for a vehicle of this price INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATIO
