If you've been searching for a capable, off-road-ready truck at a price that makes sense, this 2021 Nissan Frontier Crew Cab PRO-4X for sale at Quantum Auto Sales in Garden Grove, CA is exactly what you've been looking for. Priced at $21,995 and stocked under number 35968, this white 4WD pickup is a serious workhorse with genuine trail credentials — and it's available right now in Orange County.

About This 2021 Nissan Frontier PRO-4X

This 2021 Frontier Crew Cab comes in at 135,682 miles, which puts it squarely in the high-mileage category — but that's not the full story. The Frontier's 3.8L V6 is known for durability well beyond the 150,000-mile mark when properly maintained, and the PRO-4X trim was built to be pushed hard from day one. For buyers who want a proven off-road truck without the inflated price of a Tacoma TRD Pro or 4Runner, this is a genuinely compelling option.

The clean white exterior gives it a sharp, versatile look whether you're running it on a job site or heading up into the San Bernardino mountains on the weekend. The Crew Cab body style means you get real rear-seat space — comfortable enough for adults, practical enough for families.

2021 Nissan Frontier Performance and Engine

Under the hood sits Nissan's 3.8-liter V6, an engine Nissan introduced specifically to replace the aging 4.0L and address criticism about the previous generation. Paired with a 9-speed automatic transmission, this powertrain delivers around 310 horsepower and 281 lb-ft of torque — giving the Frontier a towing capacity of up to 6,720 pounds.

The 9-speed automatic is a significant upgrade over earlier Frontier generations, offering smoother highway cruising and better fuel economy. In 4WD configuration, this truck is equally comfortable on the 91 freeway, a job site in Anaheim, or a dirt trail out near Big Bear. The PRO-4X adds an electronic locking rear differential and Bilstein shock absorbers, meaning this isn't just a cosmetic off-road package — it's the real deal.

Nissan Frontier PRO-4X Features and Interior

The PRO-4X trim is Nissan's off-road-focused flagship for the Frontier lineup, and it brings a well-rounded feature set to match.

Technology and Connectivity

Expect an 8-inch touchscreen infotainment system with Apple CarPlay, Android Auto, and Bluetooth connectivity. The system is responsive and intuitive — no complaints from owners who've compared it against competitors in the segment.

Safety and Driver Assistance

The 2021 Frontier PRO-4X includes Nissan's Safety Shield 360, which bundles automatic emergency braking, blind-spot warning, rear cross-traffic alert, and lane departure warning into the standard package. For a used truck at this price point, that's a meaningful feature set.

Off-Road and Interior Comfort

PRO-4X-specific hardware includes all-terrain tires, skid plates, and that Bilstein off-road suspension. Inside, you get leather-appointed seating with PRO-4X badging, heated front seats, and a flat-folding rear bench that adds real utility to the Crew Cab layout.

Nissan Frontier Reliability and Ownership

The Frontier has earned a reputation as one of the toughest mid-size trucks on the market, and the 2021 model year represents a fresh start with the all-new third generation. J.D. Power gave the 2021 Frontier strong marks for initial quality, and owner forums consistently highlight the 3.8L V6 as an exceptionally reliable unit.

At 135,682 miles, the most important thing a buyer should verify is service history — specifically transmission fluid changes on the 9-speed, differential fluid condition, and whether the timing chain has been inspected. A pre-purchase inspection from a trusted mechanic in the Garden Grove or Anaheim area is always money well spent. That said, well-maintained examples of this generation have pushed past 200,000 miles without major mechanical issues.

Frequently Asked Questions

Is the 2021 Nissan Frontier PRO-4X a good buy?

Yes — the 2021 Frontier was a completely redesigned model that addressed most complaints about the previous generation. The new 3.8L V6 and 9-speed automatic are significant improvements, and the PRO-4X trim adds genuine off-road capability. At $21,995, it represents strong value for a capable 4WD truck in Southern California.

How many miles is too many on a 2021 Nissan Frontier?

The 3.8L V6 in the third-generation Frontier is built to last, and 135,000 miles is not a dealbreaker for a well-maintained example. With proper service history and a clean inspection, these trucks can realistically reach 200,000 miles or more. Focus on maintenance records and a pre-purchase inspection rather than the odometer alone.

What does the Frontier PRO-4X trim include?

The PRO-4X is Nissan's off-road performance trim. It includes Bilstein off-road shocks, an electronic locking rear differential, skid plates, all-terrain tires, leather-appointed heated front seats, the 8-inch touchscreen with Apple CarPlay and Android Auto, and Nissan's Safety Shield 360 driver assistance package.

Is a 2021 Nissan Frontier good for towing?

When properly equipped, the 2021 Frontier can tow up to 6,720 pounds. That's enough for most trailers, boats, ATVs, and small campers — making it a practical choice for buyers in Southern California who want a daily driver that doubles as a weekend hauler.
