GMC Yukon Denali Reviews

I purchased a certified used Yukon Denali XL that was 2 years old with very low mileage. After 1 year the engine had to be rebuilt along with the transmission and the rear end differential. After all that work and 4 weeks of not having my vehicle, I took my family on our annual summer road trip. About one thousand miles in, the vehicle parking brake engaged and would not release as the rear end differential had gone out once again. This time the dealership said it needed to be replaced and the part was on back order. So I was without the vehicle for weeks again and still waiting on it. Oh, and I am paying a car loan for this vehicle that I have not gotten use for.

Our 2024 Yukon has repeated engine misfires and has been in the dealership 7 times in the last 2 months, still not fixed. GMC refuses to take any accountability or stand behind the vehicles they make. Horrible customer service and company! This vehicle is a lemon, but they won’t admit it! Don’t purchase GMC!

I have a 2015 every thing work great. Love the 6.2 v8…. 93000 still looking for much more.

Thank you for your email. A few hours after receiving it, I was contacted by phone and informed that the request may not be approved and that nothing further could be done. However, we have never received any official paperwork or documentation explaining what occurred with my vehicle or why a full engine replacement was deemed necessary. This lack of communication is extremely concerning. Without a clear understanding of what happened, it is difficult to feel confident in the safety and reliability of this new vehicle.

CATASTROPHIC ENGINE FAILURE. When we bought our Yukon Denali, we were aware of the major engine‐recall issues affecting the 2019–2024 models. The salesperson at the Buena Park CA GMC dealership assured us the 2025 model year had eliminated those problems, so trusting the explanation we moved ahead and purchased.

Put 4k in the last 2 year to fix struts and air shocks. Broken sway bar links. Replaced plugs which is a pain on the last plug on the passenger side. Had the transmission flushed changed oil every 5k just to have a piston blow and a transmission and still owe 14k. Last GM I will ever buy because they don’t stand by their product and struggling hard working family’s have to eat this BS and figure out away to survive a loss that’s 1/4 of your income because who can afford to fix an engine for 16k and the vehicle is not work 16k in running condition. Who ever engineered this needs a public stoning!

🚨 Consumer Alert – GMC Denali Nightmare 🚨

I purchased a new 2020 Yukon Denali. My brand new car broke down after 4 months and was in the shop for 3 months waiting on parts. Since then I’ve had the engine replaced and every few weeks I need to bring it into the dealership because I’m getting alerts that something else is wrong with the car. I have a friend with the same car but a 2019 that has gone through 3 engines. I will never buy another GMC and tell everyone I know what lemon they sold me. The stress of having an unreliable car when driving kids is real and unacceptable when I spent so much on this terrible car.

I have a 2022 GMC Yukon Denali with 30,000 miles. Driving on the highway at 65 mph my vehicle went into limp mode without warning. Made it to the side of the road and had it towed to the dealership. Total valve body failure on the transmission. National backorder for the transmission with no ETA on the part. They also replace the valve body with a nearly identical one known to fail again. My daughter and I could have been seriously injured or killed. GMC knows about the issue and only has a remedy of a software update so the back tires don't lock up when this happens.

My family and I purchased the GMC Yukon XL Denali thinking it would be a good vehicle for the family. We could not have been more wrong. We have owned this vehicle for a little over 4 years now. We have had to replace both rear struts once. That cost us $2,000. We have had to replace the front struts twice. That is about $3,600 in front struts. GM refuses to help us and to fix the problem that is clearly due to their error. Did I mention my front struts are now locked up again and needing to be replaced for a third time? Do not buy a Yukon, run for the hills. It's unfortunate for my family that we had to learn the hard way. I grew up with a father that swore by GM products. But after seeing how they treat us as loyal customers for over 40 years we will never buy another vehicle from them again.
