ENGINE
Driving 75 mph on [XXX]. No power under gas pedal. Transmission shifted on its own to neutral and there were no lights warning on the dash. Yes my safety and that of 3 children ([XXX, XXX, and [XXX] ) as well as my mother [XXX] ) and my wife [XXX] ) were all put at risk. I had no way to accelerate or warning from the vehicle that the engine had failed. It just so happened my wife noticed it was in neutral and luckily I had room to get from the left lane to the shoulder where the speed limit is 75 mph. Dash information center said "Press start to restart vehicle". I pulled off safely to the shoulder with 7 passengers (including myself). Tried to restart the car but it was no working. The vehicle wouldn't shut off the electrical accessories either and kept repeating the same warning. The vehicle was inspected at the dealer after it was towed. There were no warning lights or signs of any issues prior to this incident. Had the vehicle for less than 2 years and under 19k miles. GM towed the vehicle to the dealership who held it for the weekend and then Monday afternoon told me the engine was blown. I was not offered a comparable vehicle under their warranty to replace it and was told I need to wait an unknown amount of time to get the vehicle back on the road as all engines are on back order.

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
My car was taken in for service in early January 2025 after just being serviced in November. The engine was making a ticking noise. The check engine light was not on, and appeared to be running fine otherwise so we drove it in for service. We were told upon inspection that the cam and lifters needed replacement, but we pushed for further inspection which found the car needs an entirely new engine, at the advice of multiple inspectors and the service department of two dealerships. Initially, the extended warranty company told us they would replace the entire engine instead of just the cam and lifters. Then they came back and said since we drove it in for repair rather than having it towed, they would not cover it. At the advice of multiple parties, it has been found this engine has so much metal in it, they've never seen anything this bad before. It is impossible it was due to driving it the 5 miles to be serviced. We have requested pictures and documentation about their findings and they are refusing to provide us with them. We have filed a dispute with the insurance company and they are not helping us.

ENGINE
With my child in the car, on a highway with no shoulder, I experienced lifter failure. It caused the vehicle shake and lose power with cars driving behind me at 55-60 MPH with nowhere to pull over. The engine just stopped as I was finally able to make it to a driveway safely. Problem was identified by dealership and my engine had to be rebuilt. I purchased the car second hand 3 months prior with no warning or symptoms. The car was inspected at the dealership by the extended warranty company rep. The extended warranty only cover a portion of the cost. The collapsed lifter cause damage to the camshaft and bent rods. The car only had 107,000 miles. If I were not able to pull off before the engine stopped, my daughter and I could’ve easily got rear ended on a Major state highway. The car was difficult to control due to the engine shaking the entire SUV.

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 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!
