When trying to start up this GMC truck, it makes all sorts of noise — surprisingly, the reason is a Duramax engine.

To add insult to injury, the truck only had 5,624 miles on the clock before it kicked the bucket.

Buying a low-mileage vehicle, one expects to be able to drive it for a long time.

Unfortunately, that wasn’t the case here.

Starting issue in GMC truck with Duramax engine stuns expert

While proper maintenance can prevent most issues, some problems cannot be avoided.

TikTok user @noeg123 shows what appears to be a GMC Sierra with a Duramax engine.

In the video, trying to start the car results in all kinds of noise from the engine.

The caption on the video also says ‘Only 5,624 miles,’ indicating it hasn’t been that long since the owner got the car.

It also shows the inside of the engine and the extent of the damage.

While Duramax engines are generally great, they are also known to have problems with the fuel system.

This problem is especially common in certain models of Chevrolet Silverado and GMC Sierra with Duramax engines.

Other than that, Duramax engines for their durability, power, and efficiency.

Even the tank from Fast and Furious 8 featured a 6.6-liter Duramax V8 diesel engine packing 800 horsepower and a whopping 1,200lb-ft of torque.

Regardless, it’s still a good practice to properly maintain your vehicle and take it for routine servicing.

Still, it’s hard to see a vehicle with such a low mileage have serious issues like these.

Fortunately, the GMC Sierra and the Chevrolet Silverado are now available in EV trims.

In addition to that, they are the best electric pickup trucks in the US, when it comes to range.

Or you can go for the good old combustion engine trim if you don’t want an EV.
