Should you buy a GMC Sierra or a Chevrolet Silverado pickup, and what’s the difference?
Imagine putting three engines in your 2024 Chevy Silverado 1500, and it has less than 15,000 miles. I would be done after two engine replacements. A Chevrolet Silverado RST Rocky Ridge owner, Bob Barnes, experienced more problems than one owner should have to deal with.
He bought the Silverado RST Rocky Ridge because it had a 6-inch suspension lift, custom wheels and tires, a custom grille, fender flares, running boards, and a cat-back exhaust system.
On the GMC Denali Diesel Duramax Owners Facebook page, he shares his dilemma.
He says, “I’m done with my 2024 Chevy Silverado 1500 RST Rocky Ridge. I’m putting the 3rd motor in it this week with less than 15k!”
“I just picked up this bad boy and couldn’t be happier. It’s a 2024 GMC Denali 3500 Ultimate with 37s on 22s, Cognita lift, pedal monster, and a bunch of other minor mods. I couldn’t be happier.”
What are the differences in engines between the 2024 Silverado 1500 RST Rocky Ridge and the 2024 GMC Denali 3500 Ultimate?
Bob continues, “I love the color. It has a full PTFE clear coat wrap and a bunch of other minor mods. The Pedal Monster in Track mode is a hoot. The 6.6 turbo puts my 6.2 to shame, and the options with the Ultimate are insane. I’m still finding new things every day.”
Now, imagine getting out of the Chevy Silverado and into the GMC Denali. The GMC Denali is an upgrade over the Chevy Silverado.
The Silverado 1500 RST is a more performance-oriented trim, focusing on sporty aesthetics and features, while the Sierra 1500 Denali is positioned as a luxury truck with upscale styling, premium materials, and advanced technology features.
Bob loves it initially, but the big question is whether he will have fewer engine problems with the GMC Sierra than with the Chevy Silverado.
The 2024 Chevy Silverado 1500 RST Rocky Ridge comes with the 6.2-liter EcoTec3 V8 engine. This engine is known for its powerful performance, offering 420 horsepower and 460 lb-ft of torque, making it ideal for towing and other demanding tasks, according to Fox Factory Vehicles.
However, Bob knows firsthand that the Silverado’s 6.2-liter V8 engine has had significant problems—three engines in less than 15,000 miles.
The GM Engine Recall
Both the 2024 GMC Sierra and Chevrolet Silverado, along with other GM models, have been recalled due to potential manufacturing defects in the 6.2-liter V8 L87 engine, according to WBIW. These defects can lead to loss of propulsion, engine damage, and failure, significantly impacting the reliability of these trucks.
Owners of both trucks have reported issues, including excessive oil consumption, lifter failures, and turbocharger problems, in their diesel models.
The GM 6.2-liter engine problems are related to unspecified manufacturing defects in connecting rod and crankshaft components. The recall applies to the Chevrolet Silverado 1500, GMC Sierra 1500, Chevrolet Tahoe/Suburban, GMC Yukon/Yukon XL, and Cadillac Escalade/Escalade ESV, but only for model years 2021 through 2024.
Does the 2024 GMC Sierra have fewer engine problems than the 2024 Chevrolet Silverado?
Bob’s 2024 GMC Denali 3500 Ultimate has a 6.6-liter Duramax turbodiesel V8 engine. He says it puts the 6.2-liter engine in the Silverado to shame. It should because the Duramax diesel engine delivers 470 horsepower and 975 lb-ft of torque.

A significant difference between the Silverado’s 6.2-liter gas engine, producing 420 horsepower and 460 lb-ft of torque.
Back to the question, will Bob have fewer problems with the GMC Sierra?
Some 2024 GMC Sierra 3500HD models, particularly those with the Duramax 6.6L V8 L5P engine, have been reported to experience engine-related issues, including stalling at low speeds or while idling.
GM Authority reports that a bulletin has been issued regarding potential stalling issues with specific 2024 Sierra 2500HD and 3500HD models equipped with the Duramax turbodiesel 6.6L V8 L5P engine.
The 2024 GMC Sierra HD with the 6.6L Duramax turbodiesel V8 engine has not been recalled for the same issues affecting the 6.2-liter engine.
The GM 6.2-liter engine problems are related to unspecified manufacturing defects in connecting rod and crankshaft components. The recall applies to the Chevrolet Silverado 1500, GMC Sierra 1500, Chevrolet Tahoe/Suburban, GMC Yukon/Yukon XL, and Cadillac Escalade/Escalade ESV, but only for model years 2021-2024.
Conclusion:
Bob will likely experience fewer engine problems with his 2024 GMC Denali 3500 Ultimate than he did with the 2024 Chevrolet Silverado RST Rocky Ridge he just traded in.
He already points out the Sierra Denali’s luxurious features and the added power and torque, which are unquestionably superior.
What About the Banks Pedal Monster?
Bob’s Sierra Denali 3500 is equipped with a Banks Pedal Monster that significantly enhances throttle response. This aftermarket feature is sure to add a fun element to his driving experience.
Will adding a Banks Pedal Monster to a GMC Sierra with a 6.6-liter diesel engine void the manufacturer’s warranty?
Adding a Banks Pedal Monster to his GMC Sierra 6.6-liter diesel does not automatically void the vehicle’s warranty. However, if the Pedal Monster causes a failure in the vehicle’s systems, the manufacturer could deny warranty coverage for that specific issue.
Banks Power reassures customers that their products are “warranty-friendly and do not leave a footprint after removal.”
Bob made a wise decision to move on from the 2024 Chevy Silverado and opt for a 2025 GMC Sierra 3500 Ultimate. He will have more power and should have fewer engine issues. At least he hopes.
