If you're searching for a 2023 GMC Sierra 1500 AT4 Crew Cab for sale in Yakima, WA, this blacked-out powerhouse deserves a serious look. Own A Car Yakima has stocked a low-drama, high-capability truck at a price point that makes a lot of sense for buyers who want late-model performance without the new-car premium.

About This 2023 GMC Sierra 1500 AT4 Crew Cab

This 2023 GMC Sierra 1500 AT4 is finished in black and carries 90,598 miles — a realistic figure for a truck that's been doing what trucks are built to do. At this mileage range, you're looking at a vehicle that's already past its early break-in phase, meaning the engine and drivetrain are well-settled, yet there's still plenty of life ahead with proper maintenance. The crew cab configuration gives you a full four-door layout with rear passenger room that genuinely accommodates adults, making this equally useful as a family hauler and a job-site workhorse. The 5 3/4-foot bed is a practical middle ground — long enough for lumber runs and gear, short enough to maneuver through town without frustration. Priced at $42,999, this truck offers exceptional value for a 2023 model year AT4 with the premium 6.2-liter engine.

2023 GMC Sierra 1500 AT4 Performance and Engine

The 6.2-Liter EcoTec3 V8 — A Cut Above

Not all Sierra 1500s are created equal, and the 6.2-liter EcoTec3 V8 is the engine that truck enthusiasts genuinely seek out. This engine produces 420 horsepower and 460 lb-ft of torque, putting it at the top of the Sierra's powertrain lineup. It's paired with a smooth 10-speed automatic transmission with overdrive, which keeps the engine in its optimal power band whether you're merging onto I-82 or towing a trailer through Yakima Canyon.

The Dynamic Fuel Management (DFM) system actively manages all eight cylinders, deactivating some under light loads to improve fuel efficiency — so you get the muscle when you need it and reasonable efficiency when you don't. 4WD means you're ready for anything Eastern Washington throws at you, from muddy agricultural roads to snow-covered mountain passes on the way to White Pass or Chinook Pass.

GMC Sierra AT4 Features and Interior

What the AT4 Trim Level Delivers

The AT4 is GMC's off-road-focused trim, positioned above the SLT and below the Denali. That means you're getting a thoughtfully loaded truck without paying for pure luxury extras you may never use. The AT4 typically includes a factory-installed 2-inch lift over standard Sierra models, multi-terrain tires, off-road suspension tuning, skid plates for underbody protection, and GMC's Pro Grade Protection package.

Inside, the crew cab is appointed with premium materials, heated front seats, a heated steering wheel, and GMC's infotainment system with wireless Apple CarPlay and Android Auto compatibility. The interior is designed around usability — large, gloved-hand-friendly controls, a rear-seat space that doesn't feel like an afterthought, and smart storage throughout the cabin. The black exterior carries a purposeful, aggressive look that suits the AT4's off-road character perfectly.

GMC Sierra 1500 Reliability and Ownership

The Sierra 1500 built on the T1 platform (introduced in 2019) has earned a strong reputation in the truck community. The 6.2-liter EcoTec3 V8 is widely regarded as one of GM's most durable and refined engines — owners regularly report 200,000-plus miles with routine maintenance. The 10-speed automatic has also proven dependable in real-world use, with smooth, predictable shifts across a wide variety of driving conditions.

Common owner feedback on the AT4 trim highlights the off-road capability as genuinely usable rather than cosmetic, and the ride quality on paved roads is notably composed for a truck with off-road tuning. At 90,598 miles, this Sierra is still well within the window where most mechanical components are reliable and replacement parts are widely available. As always, reviewing maintenance records and scheduling a pre-purchase inspection is a smart move — but this truck's mileage should not be a deterrent for an informed buyer.

Frequently Asked Questions

Is the 2023 GMC Sierra 1500 AT4 a good buy?

Yes — the 2023 Sierra AT4 with the 6.2-liter V8 is considered one of the best full-size truck configurations on the market. The AT4 trim adds genuine off-road capability, and the 6.2-liter engine is the most powerful naturally aspirated V8 option in the Sierra lineup. Buyers consistently rate it highly for towing, off-road versatility, and interior quality.

Is 90,000 miles too many for a 2023 Sierra?

Not at all. The EcoTec3 6.2-liter V8 is known for long-term durability, and 90,000 miles on a 2023 model simply means it's been actively used — not worn out. With regular oil changes and routine maintenance, this engine and drivetrain are well-suited to last well beyond 200,000 miles. It's a realistic mileage figure that reflects real use without suggesting neglect.

What does the GMC Sierra AT4 trim include?

The AT4 trim includes a factory 2-inch suspension lift, off-road suspension tuning, skid plates, multi-terrain tires, 18-inch aluminum wheels, heated front seats, a heated steering wheel, wireless Apple CarPlay and Android Auto, GMC's MultiPro tailgate, and distinctive AT4 badging inside and out. It's a purpose-built off-road package on top of an already well-equipped truck.

How much can the 2023 GMC Sierra 1500 with the 6.2L tow?

When properly equipped, the 2023 GMC Sierra 1500 with the 6.2-liter V8 is rated to tow up to approximately 13,000 pounds. Actual towing capacity varies based on configuration, but this engine and transmission combination make it one of the strongest towers in the half-ton segment — fully capable of hauling trailers, boats, RVs, and equipment across Yakima County and beyond.

Does the AT4 have a locking rear differential?

Yes. The GMC Sierra AT4 comes standard with an Eaton locking rear differential, which is a major advantage in genuine off-road or low-traction situations. Combined with the electronic 4WD system and skid plates, the locking diff makes the AT4 meaningfully more capable off-road than cosmetically styled "adventure" trucks.
