I would like to express my frustration and concern regarding a serious issue with our brand-new 2025 Yukon Denali truck. The vehicle, which has only 934 miles, has experienced a transmission failure. We picked the vehicle up on [XXX] and since February 27th, it has been at the dealership for repairs—now more than a full month. Initially, the torque converter was replaced, but that did not resolve the issue. After only a mile or two of driving, we returned the truck back to the dealer for further evaluation. Subsequently, after consulting with technical assistance, the dealership confirmed that the valve body needs replacement. As I'm sure you're well aware, this part is backordered nationwide, adding significant delays to an already troubling situation. It is hard to comprehend how a brand-new truck can fail virtually right off the assembly line. I am disappointed that we have had to deal with such a significant defect and even more disheartened by the extensive wait for repairs. This experience has left us questioning the safety and reliability of our vehicle. Given the circumstances, I believe more should be done to resolve this matter quickly and effectively for us. GM has been well aware of this transmission for years. The most recent recall dated December 13, 2024 for the same issue on the 2021 – 2022 model years of most of GM’s product line suggest this problem has not only been a known issue for many years but with the failure of my new vehicle for the same issue proves that they have not done anything about it. This leads me to believe that my safety is just as at risk as anybody else in the earlier named recall and therefore this recall should be extended to include all current models. GM should be forced to resolve this issue for existing vehicles before they build any new defective vehicles and sell them to unsuspecting customers like myself. Thank you for hearing me out, I look forward to your guidance. Jason FYI there is an interesting article o INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORM

RPM’s started to fluctuate while driving with cruise on. Noticed no issue with shifting until torque converter grenaded blowing metal through the transmission 2 days later. Transmission has been replaced with GM reman by a GM dealer. New transmission lags going into gear when it’s cold and shifts hard. GM tech said this is common and no way to correct it without replacing it again.

My engine blew up while merging onto the interstate. The vehicle completely shut down. A few minutes prior I could tell there was an issue but until that moment there were no warning lights or issues that could be detected. Vehicle has been at the GMC dealership almost a month waiting for a new engine that is currently on back order

ENGINE
Was driving normal down interstate. Interstate has two barrie walls making it a two lane road with no shoulders. Car was almost rear ended 3 times while it was stopped in middle of interstate. Me, my husband, my [XXX] , [XXX] and [XXX] were all in the car. I had to jump out the car while it was still rolling to make sure my children made it to safety before someone didn’t see us and hit us at 70mph. We had to cross the road and jump over a barrier in the construction zone. It took our high way patrol 35 mins just to show up and shut the road down to get the vehicle moved. According to the GM mechanic, a rod went through the block causing a hole. There was no warning of this happening, the car made noise and the vehicle automatically said low oil pressure, shut vehicle off, then an instant pop and smoked everywhere. The motor is on back order and won’t be able to be replaced for over 6 months if that. We had just purchased the vehicle and the motor was blown not even 3 hours after owning it.

VISIBILITY/WIPER
On multiple occasions, more recently 03/28/2025, the windshield wipers would stop working. On 3/28/25 in pouring rain at night the front windshield wipers were working and then stopped. The rear window continued to work. I finally found somewhere to safely pull over and check fuses for front and back wipers. They were both good and I even swapped the fuses for front and back and the back wipers continued to work while the front would not. This continued on our our trip in rain and even the next morning the front wipers would not come on. An hour later driving (with the wiper switch in the OFF position) the front wipers came on. I switched the switch to on and they were functioning. This has happed several time in the 6 months of new ownership with the dealership denying they have ever heard of such a problem. As we arrived to our destination and telling the story to the other families we were meeting another family there said they just had the same exact problem on their 2024 Yukon denali on the trip too. This put 2 families in a very dangerous situation. As I google this problem there are multiple reviews of individuals with this same problem.

New Denali less then 1 year old had lifter problems and needed lifters replaced and a camshaft. Started knocking while driving on the highway and tough to travel 4 lanes to get off the road. This is a serious issue.Very concerned because of widespread problems. I hope NHTSA does the same thing they did with Kia regarding the 2.o turbo engines. My last car was a Sorento 2.o turbo with defective engine. Kia agreed to a lifetime warranty for that failure. Luckily they did because mine failed and they replaced the engine. Once replaced I bought the Yukon. Bame similar issue. I hope a settlement included lifetime warranty.

The pump in the power-assist brakes puts out less vacuum power than needed, increasing stopping distance and the risk of a crash. My car rolls and doesn't stop. I have new brakes so this is unacceptable!!

UNKNOWN OR OTHER
Hello, I’m calling about the GM transmission recall recently announced in March 2025 affecting 2020 Yukon vehicles. My Yukon experienced what I believe is the exact same issue described in the recall. Our vehicle lost forward gears and almost caused a crash. A certified mechanic confirmed the transmission fluid was burnt and full of clutch material, with internal transmission damage. We are asking for this to be handled under the recall, as the issue directly matches GM’s known safety defect. We need this resolved immediately — the vehicle is unsafe to drive and the failure happened before we even knew about the recall. Our GMC Mechanic stated the following : Needs immediate attention Recommended service Transmission: test drove verified no forward gears after 3 minutes of driving. fluid brown and burnt full of clutch material. internal damage to transmission. A transmission flush is a process that makes it possible to clear the old transmission fluid from the vehicle's transmission. This process also helps to remove residue of older transmission fluid from the converters, coolers, and cooler lines that often are part of the design for the transmission.

No response from GM other than "waiting on diagnosis" No loaner or rental provided. Still under warranty. 6.2 v8. Engine failure suspected. I am reporting this to help switch the investigation to an actual recall of the wide-spread issue with this engine. No documentation written information provided by GM.
