    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!

      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.

      The vehicle completely stalled while driving uphill in an area where I live that frequently experiences snow and icy road conditions. This creates a serious safety risk. Thankfully, this did not occur on a freeway where traffic speeds exceed 65 mph. I also regularly travel with my 17-month-old child in the vehicle, which makes this situation even more alarming. My concern is not only about the mechanical failure itself, but about the safety implications and the apparent lack of urgency in addressing them. I respectfully request full documentation regarding the engine issue and a clear explanation of the decision that was made.

      I am writing regarding my 2025 GMC Yukon, which required a complete engine replacement at only 10,000 miles. While the repair was performed under warranty, a full engine failure at such low mileage is extremely concerning for a brand-new vehicle. This type of major powertrain defect substantially impacts the vehicle’s reliability, long-term value, and overall confidence in its safety. A complete engine replacement is not a minor repair, and it raises serious concerns about future performance and durability.

      I understand that repair attempts are one factor considered under lemon law guidelines; however, a defect of this magnitude may also qualify as a substantial impairment to the use, value, and safety of the vehicle. Additionally, any time the vehicle was out of service should be taken into consideration. Given these circumstances, I am formally requesting that this matter be reviewed for potential repurchase or replacement consideration. At minimum, I would like this complaint documented and escalated to the appropriate review team. Please confirm receipt of this email and provide a case number for my records. I look forward to your response and a resolution that reflects the seriousness of this situation.

      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.

      Only two months and nine days into ownership—and with less than 2,000 miles on the odometer—we drove from Southern California to Scottsdale, Arizona (about 2,381 miles on the vehicle) when the engine catastrophically failed, as the local service manager called it. The engine had seized unexpectedly and left us stranded five hours from home. We’ve been verbally told that the car now requires a new engine, radiator, piping, fuse box and new wiring—though the dealer has yet to provide an official diagnostic. To experience such a devastating failure in a brand-new, premium vehicle is not only shocking—it’s deeply disappointing and stressful.

      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 my 2020 GMC Yukon XL Denali for over $82,000 in 2021, expecting a reliable premium vehicle. Instead, it has been nothing but catastrophic engine failures:
      • 3/2024: Oil pump failed (covered under warranty). After repairs, my check engine light stayed on.
      • 4/2024: Vehicle broke down again. Paid $500 to tow it. Camshaft & lifters replaced under warranty.

      • 8/2024: Vehicle failed AGAIN, broke down during a test drive, had to be towed back. Now I’ve been told it needs a new engine ($20,000)—but warranty is expired.

      I have already invested over $130,000 in payments and repairs—and I am still making monthly payments on a vehicle that doesn’t even run. GM’s only “solution” was offering me a loyalty certificate toward buying a new vehicle—which is not a real resolution when I already own one that doesn’t work. I’m left paying for a “luxury” vehicle that I can’t even drive. All I’m asking is for GM to stand behind their product and cover the engine replacement or provide a fair resolution. A vehicle with repeated failures like this should not be the burden of the customer. Please share my story—maybe together we can hold GM accountable.

      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.

      Title: GMC Denali: A Costly Nightmare with Poor Customer Service

      Rating: ★☆☆☆☆ (1/5)

      I purchased a GMC Denali six months ago for a hefty price tag of $96,000, expecting a premium driving experience and the reliability that usually comes with a luxury brand. However, my experience with this vehicle has been nothing short of a nightmare, and the customer service from GM has been equally disappointing.

      The trouble began when I started experiencing electrical issues with the vehicle. These issues culminated in a terrifying incident on the freeway, where the car dangerously shut off, forcing me to coast to safety amidst high-speed traffic. This incident not only put my life in danger but also posed a significant risk to others on the road.

      When I reached out to GM for assistance, I expected a prompt and reassuring response. Instead, I was met with disappointment and frustration. GM has refused to cover the cost of a replacement vehicle while I wait for the new engine to be installed. This has left me in a vulnerable position, having to pay for a rental car for three weeks and counting, which is an added financial burden that I never anticipated.

      What's even more disheartening is GM's dismissive attitude toward the situation. Their response was, "sometimes new cars need new engines," which is an unacceptable and callous way to address a problem of this magnitude. A car that costs nearly $100,000 should not require such a major repair within the first six months of ownership, and GM's failure to take responsibility for this issue is both infuriating and unacceptable. Furthermore, the staff at GM have been elusive and show a profound lack of concern for their customers' safety and satisfaction. It's as if they've forgotten the importance of customer loyalty and the reputation of their brand.

      In conclusion, my experience with the GMC Denali has been a costly and dangerous ordeal. GM's unwillingness to provide adequate support and their dismissive attitude towards the issue have left me deeply dissatisfied. I expected more from a brand that claims to offer luxury and reliability, but what I received was nothing but disappointment and frustration. Buyers beware, and think twice before investing your hard-earned money in a GMC Denali.
