2021 Dodge Durango SXT Plus Overview: Features, Performance, and Value

The 2021 Dodge Durango SXT Plus represents a pivotal middle ground for enthusiasts and families seeking a muscular, three-row SUV without the premium price of V8 models. Positioned just above the base SXT, this trim balances essential utility with upgraded comfort features and a refreshed interior design.

The Significance of the 2021 Model Year Refresh

By the time 2021 arrived, the third-generation Dodge Durango (the WD platform) had already established itself as a stalwart in the mid-size SUV segment. However, 2021 was the year Dodge implemented a significant mid-cycle refresh that breathed new life into the aging platform. While the exterior received aggressive styling cues borrowed from the Dodge Charger, the interior underwent a comprehensive overhaul.

For the SXT Plus trim, this meant moving away from the more utilitarian dashboard of previous years toward a driver-centric "cockpit" design. This change was not merely aesthetic; it improved ergonomics and integrated better materials, making the 2021 Durango feel considerably more premium than its 2020 predecessor. In 2026, looking back at this model year, it remains a "sweet spot" for used buyers because it offers modern Dodge styling and updated technology without the extreme complexity of subsequent all-electric or hybrid transitions seen in the broader industry.

Defining the SXT Plus: What the "Plus" Package Adds

The "Plus" designation on the SXT trim is more than just a badge; it is a specific equipment group designed to address the most common complaints regarding the base model. While the standard SXT focused on fleet sales and budget-conscious entry-level buyers, the SXT Plus was aimed squarely at the retail consumer.

Key additions included in the SXT Plus over the base SXT typically include:

• 8-Way Power Driver’s Seat: Replacing the manual adjustment, this allows for much finer control over driving position, including 4-way power lumbar support.
• Bright Roof Rails: These provide both a stylistic "chrome" accent and the functional capability to add crossbars for cargo boxes or bike racks.
• ParkSense Rear Park Assist: A critical safety feature for a vehicle of this size, providing audible alerts to prevent low-speed collisions while reversing.
• SiriusXM Satellite Radio: Usually bundled with a trial subscription, enhancing the infotainment experience.

In the secondary market of 2026, these features are often the difference between a vehicle that feels like a "work truck" and one that feels like a "family SUV."

Performance: The Reliability of the 3.6L Pentastar V6

Under the hood of every 2021 Dodge Durango SXT Plus is the venerable 3.6-liter Pentastar V6 engine. In this application, it produces approximately 293 to 295 horsepower and 260 lb-ft of torque. While Dodge is often associated with high-displacement HEMI V8s, the Pentastar V6 is the unsung hero of the lineup for several technical reasons.

The Torque Curve and Transmission Pairing

The engine is mated to the TorqueFlite 8-speed automatic transmission (an FCA-licensed version of the ZF 8HP). This transmission is widely regarded as one of the best in the industry, offering smooth shifts and an ability to keep the V6 in its optimal power band. Unlike many competitors that shifted to Continuously Variable Transmissions (CVTs) for fuel economy, the Durango’s traditional geared automatic provides a more tactile and predictable driving experience, especially when merging onto highways or navigating hilly terrain.

Fuel Efficiency and Range

The V6 allows the Durango to achieve an EPA-estimated 19 mpg in the city and 26 mpg on the highway for Rear-Wheel Drive (RWD) models. All-Wheel Drive (AWD) models see a slight dip of 1 mpg. With a massive 24.6-gallon fuel tank, the SXT Plus boasts a highway cruising range of over 600 miles, making it an exceptional choice for long-distance road trips—a trait that remains highly valued in 2026.

Interior Craftsmanship and Cargo Versatility

The 2021 refresh introduced a dashboard inspired by the Challenger and Charger, featuring a slight tilt toward the driver. In the SXT Plus, the materials are a mix of soft-touch plastics, metallic accents, and durable cloth upholstery.

Seating Configurations

One of the unique aspects of the 2021 Durango SXT and SXT Plus was the flexibility in seating. While the Durango is known as a three-row SUV, the SXT Plus was available in two primary configurations:

1. Five-Passenger Layout: The third row could be deleted, resulting in a massive rear cargo area and lower vehicle weight.
2. Seven-Passenger Layout: The most common configuration, featuring a 60/40 split-folding second row and a 50/50 split-folding third row.

The third row in the Durango is notably more adult-friendly than many of its "crossover" competitors. Because the Durango is built on a rear-wheel-drive-based platform with a long wheelbase, the packaging allows for more legroom in the rear-most section.

Cargo Volume

With all seats folded flat, the Durango SXT Plus offers up to 85.1 cubic feet of storage space. Even with the third row in use, there is still 17.2 cubic feet of space—enough for a standard grocery run or a few small suitcases. The "Fold-and-Tumble" second-row seats make accessing the back easy, a design choice that has aged well in terms of mechanical simplicity and durability.

Infotainment: The Uconnect 4 System

While higher trims in 2021 (like the Citadel or R/T) could be equipped with the newer 10.1-inch Uconnect 5 system, the SXT Plus typically came standard with the 8.4-inch Uconnect 4 system.

Despite being the "older" generation of software in 2021, the Uconnect 4 is highly regarded for its stability and ease of use. It features:

• Apple CarPlay and Android Auto: Wired connection via USB.
• Integrated Voice Command: Allowing for hands-free calling and media selection.
• Dual USB Ports: Located in the front console for charging and data.

For many owners in 2026, the 8.4-inch screen is actually preferred over newer, fully-digital interfaces because it retains physical knobs for volume and tuning, as well as physical buttons for the climate control system located just below the screen. This reduces driver distraction compared to the screen-heavy layouts of later vehicles.

Towing Capacity: Best-in-Class Utility

One of the strongest arguments for choosing a Durango SXT Plus over a comparable Honda Pilot or Toyota Highlander is its towing capability. Even with the V6 engine, the 2021 Durango SXT Plus is rated to tow up to 6,200 pounds when properly equipped with the Trailer Tow Group IV.

This package includes:

• Class IV Hitch Receiver
• 7-and-4-pin Wiring Harness
• Heavy-Duty Engine Cooling
• Rear Load-Leveling Suspension

The load-leveling shocks are a mechanical marvel for this price point; they use the motion of the vehicle to pump up the rear dampers, ensuring the SUV remains level even when hitched to a heavy trailer or fully loaded with cargo. This prevents the "sagging" rear end that compromises steering and braking performance in other SUVs.

2021 Dodge Durango SXT Plus Technical Specifications

The following table summarizes the key technical data for the 2021 SXT Plus trim.

Safety and Driver Assistance

In 2021, Dodge began making more safety features available across the lower trims, though many remained optional. The SXT Plus comes standard with a robust airbag system, electronic stability control, and the aforementioned rear park assist.

However, when looking for a used 2021 model in 2026, buyers should check if the original owner opted for the Technology Group. This package added:

• Adaptive Cruise Control: Maintaining a set distance from the car ahead.
• Forward Collision Warning Plus: Capable of autonomous braking if a collision is imminent.
• Lane Departure Warning Plus: Providing steering torque to help keep the vehicle in its lane.

The structure of the Durango is based on a unibody design with high-strength steel side-guard door beams, which contributed to its solid performance in crash testing during its production run.

Ownership Considerations in 2026

As the 2021 Durango SXT Plus enters its fifth year of service for many owners, certain maintenance trends have emerged. The Pentastar V6 is generally considered a "100,000-mile-plus" engine, but owners should be aware of a few common areas for inspection:

1. Oil Filter Housing: On higher-mileage units, the plastic oil filter housing can sometimes develop leaks. Many owners in 2026 replace these with aftermarket aluminum versions for a permanent fix.
2. Uconnect Screen Delamination: Some 8.4-inch screens from this era were prone to "ghost touching" or delamination. Ensuring the vehicle has been kept in a garage or using a sunshade helps preserve the adhesive.
3. Brake Wear: Because the Durango is a heavy vehicle (approaching 5,000 lbs with passengers), brake pads and rotors may require replacement more frequently than in a lighter sedan.

The cost of ownership remains competitive because parts for the 3.6L engine and the WD platform are widely available and relatively inexpensive compared to European luxury SUVs of the same size.

Frequently Asked Questions

Does the 2021 SXT Plus have leather seats?

No, the SXT Plus comes standard with high-quality cloth bucket seats. If you find a 2021 Durango with leather at this trim level, it likely has aftermarket covers (like Katzkin) or was part of a specific dealer-installed package. For factory leather, you would typically need to move up to the GT or Citadel trims.

Is the AWD system in the Durango SXT Plus full-time?

The AWD system in the V6 Durango is an "active" system. It primarily sends power to the rear wheels to maximize fuel efficiency but can instantly transfer torque to the front wheels if slip is detected. It does not have a low-range transfer case; that feature is reserved for V8 models equipped with the two-speed on-demand AWD system.

Can the 2021 Durango SXT Plus run on E85?

Many versions of the 3.6L Pentastar V6 are Flex-Fuel compatible, but it depends on the specific emissions calibration for the region where it was originally sold. You can verify this by checking for a yellow gas cap or a "Flex Fuel" badge on the tailgate.

How does the SXT Plus handle in snow?

When equipped with AWD and the standard 18-inch wheels, the Durango is exceptionally capable in winter conditions. The 18-inch wheels provide a taller tire sidewall than the 20-inch wheels found on higher trims, which actually improves ride quality and traction on unplowed roads.

Is there a difference between the 2021 and 2022 SXT Plus?

The changes were minimal. In 2022, Dodge made some of the SXT Plus features standard on the base SXT and eventually streamlined the trim levels. However, the 2021 model remains significant because it was the first year of the updated interior, which is the most noticeable improvement for daily drivers.

Final Recommendation

The 2021 Dodge Durango SXT Plus is a pragmatic choice for those who need a "real" SUV—one capable of towing a boat or carrying seven people—without the high fuel costs or insurance premiums associated with the V8 trims. In 2026, it stands out as a reliable, traditionally engineered vehicle that avoids the over-complication of modern hybrid powertrains. For the best experience, seek out a model with the Trailer Tow Group IV and the Popular Equipment Group (which adds a power liftgate and heated front seats/steering wheel) to maximize the vehicle's utility and comfort.
