GMC's Sierra 1500 in black looking sleek against a nice brick building with evergreen trees in front. The GMC Sierra 1500 has been popular for decades, and some of our customers at Summit GM are repeat customers, completely loyal to this model.

The GMC Sierra 1500 has been a mainstay in the full-size truck market since 1999. Over its five generations, the model has earned a reputation for reliability and versatility, offering a range of engines from a 2.7L turbocharged four-cylinder to a 3.0L inline-six turbodiesel with mild-hybrid assist.

The Sierra 1500’s three cab styles and two bed lengths cater to a variety of uses and consumer preferences, making it a versatile choice for many buyers.

So, where does the Sierra 1500’s reliability stand when compared to its competitors? The Sierra 1500 actually scores slightly higher than its sibling, the Silverado 1500, in J.D. Power reliability ratings! And it stands above average against its direct competition as well; at 85/100 in J.D. Power ratings overall and 84/100 in the reliability category, it's got the support of consumers as a wise investment.

At the same time, the Sierra 1500 is known for plentiful towing, hauling, off-roading, and providing a highly comfortable experience for families. It's got a great reputation as a reliable full-size truck— and one that's really well earned.

As the sibling of parent company's GM's highly reliable Chevrolet Silverado 1500—this vehicle offers a similar driving experience with exemplary peace of mind.

The GMC Sierra 1500's Place in the Full-Size Truck Segment

Even though the Sierra 1500 shares a lot of the bones of the Chevrolet Silverado, but it still successfully distinguishes itself on the stage of full-sized trucks. And it's competitive!

The Sierra 1500 isn’t just a reliable choice; it’s also a popular one. In 2023, US sales of the GMC Sierra 1500 grew by 65.1% from 2022, indicating its growing share in the full-sized truck market.

Behind GMC Sierra 1500's Reliability

Closeup of the Sierra 1500 in black featuring distinctive exterior design The GMC Sierra 1500 has a lot going on under the hood and on its exteriors; our customers at Summit GM often ask us what's new, and what's working over decades, which is why we wanted to get the word out! This vehicle is exceptionally reliable.

The Sierra 1500’s reliability stems not only from its reputation but also from meticulous engineering. The newer models all offer a variety of engine options, with some standard depending on trim, including:

  • Turbocharged inline-four cylinder
  • 3.0L inline-six turbodiesel engine
  • 5.3L V8
  • 6.2L V8

Trims are highly variable no matter what engine you choose, and it all helps reliable performance. A heated steering wheel, coupled with an eight-speed automatic transmission, optional adaptive dampers, and up to 22-inch wheel options, ensure a smooth ride in different environments.

V8s top the list in terms of reliable power to weight ratio. But some of Summit GM's customer's prefer economy to raw force. Turbocharged options make great alternatives in case you're getting the most out of smaller displacement volumes.

Turbocharged Engine Options

In terms of engine options, the Sierra 1500 certainly delivers. In addition to powerful V8 options, it offers a turbocharged four-cylinder and a Duramax inline-six diesel option, great for variable performance needs you might have for life in Fort McMurray. Not every truck needs maximum power!

The turbocharged 2.7L four-cylinder engine, in particular, delivers a useful 310 horsepower and 420 pound-feet of torque, making it an agile choice for those in need of power and economy.

For off-road enthusiasts, the AT4X variant of the Sierra 1500 comes with a standard 305-hp turbocharged 3.0L inline-six Duramax diesel engine, offering dependable performance even in challenging conditions.

Towing and Hauling Capabilities

The Sierra 1500, as practical as it is powerful, boasts remarkable towing and hauling capabilities. The newer models, for instance, can tow between 8,700 to 13,300 pounds, depending on the configuration:

  • SIERRA 1500 PRO, SLE, ELEVATION & SLT trims: up to 13,000 lb
  • SIERRA 1500 AT4: up to 9,000 lb
  • SIERRA 1500 DENALI: up to 9,200 lb
  • SIERRA 1500 AT4X: up to 8,700 lb
  • SIERRA 1500 DENALI ULTIMATE: up to 8,900 lb

The truck’s payload capacities also vary based on the engine choice, ranging from a maximum of 1,820 pounds for the 6.2-liter V-8 model to 2,500 pounds for the 5.3-liter V-8 model. Nothing to brush off!

The Sierra 1500 actually yields a maximum of 13,300 lb—depending on towing package— and caters to many different needs and preferences our customers have in northern Alberta.

Build Quality and Durability

Higher trims of this truck feature a unique carbon fiber composite bed that’s lighter and stronger than traditional steel beds, embodying GMC’s commitment to durability.

Inside, the Sierra 1500 is equally impressive. The interior is well-constructed with premium materials, reflecting the improvements made over previous generations. GM's latest models come to life in the Denali trim especially.

Denali Build Quality

The build quality of the Sierra 1500 is undeniably impressive, particularly in the Denali trim level. The Denali represents the pinnacle of GMC's craftsmanship, featuring an interior adorned with premium materials such as open-pore wood trim, accented with real wood and aluminum trim.

It also sports high-quality leather that is both supple and durable— designed to withstand the test of time. Every aspect of Sierra 1500's construction comes alive from the solid feel of the door handles to the precise fit and finish of interior components.

The Cost of Ownership and Maintenance for GMC Sierra 1500

Ownership of a truck such as the Sierra 1500 has its costs like any vehicle. But the benefits of maintaining this vehicle and prolonging its useful life are worth those costs.

The average annual maintenance cost for the Sierra 1500 is around CAD $935. It's comparable to the Chevrolet Silverado, at CAD $918 per year on average. Both models score above average on reliability with respect to repair affordability, with the GMC Sierra 1500 scoring 3rd out of 17 full-sized trucks in the running.

Anticipated Maintenance Expenses at High Mileage

Keep in mind, however, that the Sierra 1500’s likelihood of needing a major repair increases as it ages. Annual maintenance costs for the Sierra 1500 represent an incremental increase over time, starting at approximately CAD $410 in the first year and potentially rising to about CAD $2,450 by the 12th year.

By the tenth year, the chance of a major repair rises to 26.25%. While this might seem high, it’s a common trend among vehicles as they age, and not unique to the Sierra 1500.

Understanding these potential expenses helps owners to budget effectively for the upkeep of their truck. If you keep visiting Summit GM for service, and later GMC parts, you can reliably ensure that your Sierra 1500 remains in great shape for many years to come.

Fuel Economy Across Trims

Fuel economy also plays a significant role in assessing a vehicle’s cost-effectiveness and reliability. The Sierra 1500’s fuel economy varies across trims and engine options.

For instance, the V8 engines level have decent combined average fuel consumption rates depending on engine displacement:

  • 5.3L V8 GMC Sierra 1500 4WD: 13.8 L/100km
  • 6.2L V8 GMC Sierra 1500 4WD: 14.7 L/100km

However, if fuel efficiency is a priority, the optional diesel engine is a game-changer. It provides significant fuel economy benefits, also depending on trim and AWD or 2WD configurations:

  • 3.0 L 6-cylinder Turbodiesel GMC Sierra 1500, 2WD: 9.4 L/100km
  • 3.0 L 6-cylnder Turbodiesel GMC Sierra 1500 AT4X, 4WD: 12.4 L/100km

Choosing the diesel engine can contribute significantly to the Sierra 1500’s ownership costs, affecting reliability overall. Either way, you can enjoy long lasting fuel efficiency no matter your choice.
