   On July 14, 2026, I experienced a serious fuel system failure with my 2023 GMC Denali. That morning, I filled the vehicle with a little over 20 gallons of fuel at a gas station approximately two miles from my home.

   The car just died while going 55mph on the highway. Complete shutdown but luckily both the steering and brakes worked. After stopping it wouldn’t start again. I had my three children in the car aged [XXX], [XXX], and [XXX]. It was a horrific experience. GMC did some repairs to the engine that took over two months and then the car had a few more warnings pop up just a few weeks later. GMC now says there is a misfiring in one of the positions. I’m terrified of driving this car…

   The vehicle has the L87 GM engine. It lost complete power and the engine seized up and would not start again. Fortunately I was able to roll into a neighborhood and get off the main road with no issues. The dealer has confirmed the seized engine and a replacement engine has been ordered with no ETA. There was no prior warning of the failure, besides a shuddering, like I was running out of gas, and then a lose of complete power.

    It has been several months since recall on L87 was issued. My truck now has over 44k miles and I’ve contacted the dealer, they note there’s no fix in sight.

I’m now stuck with this potentially dangerous vehicle with no fix, and am concerned. I also can’t get a fiar trade in value due to open recall. Overall, I’m stuck with a defective vehicle that…
