ENGINE, UNKNOWN OR OTHER
Driving on highway. The vehicle jerked and started to make squeaking, clunky sounds. Gas stopped flowing to the vehicle. Then the vehicle became inoperable. No warning light or alerts or sounds occurred before or after. It was a complete surprise.

ENGINE, POWER TRAIN
The motor is randomly revving at braking so far only under 10 miles an hour. Yesterday it stalled twice on me and cut off braking under 10 miles an hour. I had to come to a complete stop while restarting the vehicle. Definitely has me worried if it happens on the highway or higher speeds.

ENGINE, FUEL/PROPULSION SYSTEM
After the vehicle was serviced with a fuel injection cleaning and an oil change (by a GM dealership), the vehicle lost about 5 miles per gallon while driving and has not improved since. . I brought the vehicle back to the same dealership and complained. Another fuel injection cleaning was performed, but it did not help. It has been about 3 months and nothing has improved. I use 93 octane, TopTier gasoline.

ENGINE
While driving in traffic at 65mph, the engine stopped running, car went into neutral and there was no power for brakes or steering. I luckily made it to the side of the road. Vehicle was towed to my dealer ( Cardinal Buick GMC, Belleville, IL), where after 3 days they informed me that the engine was ruined, 2 main bearings were damaged and 4 of the 8 connecting rods were damaged. GM made the decision to replace the motor, but no time frame was given, I was told 2 to 3 months. The dealership did give a loaner car. My Yukon Denali was 1 year and 4 days old with 15, 882 miles on it.

On January 23, 2025, at approximately 7:00 p.m., I was traveling on I-10 when, without warning, my engine shut off on my 2022 GMC Yukon, and I rapidly lost speed. We managed to pull the vehicle off the road. This was extremely frightening since there was traffic on I-10.

ENGINE
On March 3, 2025, my 2024 GMC Yukon had a rattle/knock. The engine quit running and would not restart. The Yukon had to be towed to the dealership for diagnosis and repair. The dealer indicated that the engine required replacement due to metal shavings and bearing damage. The Yukon had 6450 miles when the failure occurred. The engine was replaced. This vehicle was purchased new in September 2024. This failure occurred while on the road at a traffic light and the Yukon could not be moved out of the traffic lane. Sheriff notified to provide scene safety while waiting for tow vehicle and during loading onto tow vehicle. No traffic accident occurred. There were no warning lamps on the dash or warnings on my phone app immediately prior to the failure.

ENGINE
We were driving our 2023 GMC Yukon AT4 from Phoenix, Arizona to Flagstaff, Arizona, which is about 2.5 hours north. A few hours into our drive, about 40 miles away from Flagstaff, as we were driving ~75mph on the [XXX] highway (in the middle of nowhere), all of the sudden our GMC just stopped working - it started slowing down on its own, put itself into Neutral, and nothing was working. We were able to pull over to the side of the road where we used OnStar to reach GMC Service, who called us a tow truck. As we were on with OnStar we tried restarting the vehicle and nothing was responsive. For hours our family, two adults and one child, were stuck on the side of the [XXX] highway with semi-trucks flying by us waiting for the tow truck. We were then told the two truck could only fit two persons, so I had to order my own Uber to pickup myself and my son in the middle of nowhere, leaving my husband to wait alone, dangerously, for the tow truck. Important to note a major winter storm was coming in this afternoon, so with no power it was also freezing cold in the broken down vehicle. The GMC was towed to the Chevy dealer/service center in Flagstaff, who was able to have a mechanic look at the vehicle that day. After a few hours they contacted us and let us know the entire engine blew and would need to be replaced. They let us know this is a "known issue" with certain Chevy/GMC/Cadillac SUV's that have the 6.2 engine. We purchased this vehicle brand new in late 2023 - at the time of this "catastrophic engine failure" issue, it had only ~12,000 miles on it. We were forced to leave our GMC in Flagstaff for repair, and told it would likely be 4 weeks or more to get the new engine. We were also left without a 4x4 vehicle for the entirety of our "vacation" in a major winter storm. There were no warning lamps, messages, or other symptoms of the problem prior to failure.

Nuna is not responding to customers questions or concerns adequately. They continue to just send you to their recall page. Complaints are as follows: - They also aren't honoring their warranty and replacing or repairing carseats still under warranty. - This recall is also causing damage to other components of the carseat (such as the strap - fraying, other use issues) that Nuna is not addressing. - It took Nuna over 4 months to send out the repair kit. After I contacted them, not vice versa. - The recall replacement seat cushions are extremely difficult to get on the seats, not color matched (the main reason this matters is because customers paid higher prices for various colors and they aren't being made whole financially). This is clearly not a universal fit for all year models. Even adult men are struggling to get these cushions on the chair by pulling them incredibly hard to fit. -Their carseats associated with the recall are failing at random, not in predictable replicable ways. I've had several instances where a child was strapped in and tightened only to find the straps completely loosened as the destination. The variables of child weight in the seat and movement are not being factored into the safety tests associated with this recall. You are testing an empty seat completely cinched down - not realistic to everyday conditions when in use. -Once you repair the carseat it's difficult to get everything lined up perfect to know the button is functioning exactly as designed. I now pull aggressively on the seat straps multiple times every time before I take off to make sure all is well. That doesn't feel like a safety win. -Customers are left with fixing the issue themselves (lots of time spent!). Nuna takes no accountability. Nuna's responses have been horrible. Customer service gets an F. As a repeat customer I am extremely disappointed. I have explored all avenues with Nuna and as a result am filing a NHTSA complaint.

ENGINE
Engine locked up / froze up while driving 75MPH on interstate i-10. Vehicle is now in the shop awaiting a new engine. It will probably lock up as well, finding there is no known guaranteed reason for this engine failure. Dealership provided a junk rental and said it would be a few months before repair is complete. My towing bills were not paid by GM. My insurance had to pay which is simply not right! I'm sure they will pull a mystery motor off the shelf and hope for the best... Very dangerous!

The contact's wife owns a 2024 GMC Yukon. The contact stated that while driving at 80 MPH, several warning lights flashed on the instrument panel as the engine shut off. The vehicle's speed abruptly decelerated as the contact was nearly hit by an 18-wheeler traveling close behind the vehicle. The contact managed to coast the vehicle as best as possible off to the shoulder of the highway. The vehicle was towed to a dealer and a diagnostic was performed which showed that the engine had failed. The contact stated that both he and his son suffered emotional trauma as a result of the sudden failure; however, neither has yet to seek medical treatment. The manufacturer was notified of the failure and the contact was offered a new engine despite the contact's request for a vehicle buyback. The contact stated that he did not feel safe driving the vehicle and feared for both his and his family's life as a result of the failure. The vehicle remained in the possession of the dealer and was not repaired. The failure mileage was approximately 22,000. The VIN was not available.

I was traveling on the highway when my 2023 Yukon Denali engine shut off and switched to the neutral gear with any warnings. The dashboard display read "press start again" as I coasted to the shoulder of the highway. I was able to put the vehicle in "park" and re-start the engine after a couple of tries. I got a couple miles down the road, got off on an exit ramp then it shut off again and I again coasted to the shoulder of the highway. Again the display read "press start again", but this time the vehicle would NOT restart at all. I had full electrical power in the vehicle during both engine failures. I had the vehicle towed to my local GMC dealership. The dealership told me that I needed a new engine after assessing the vehicle.
