Its popularity stems from its legendary Kenworth build quality, configurable options, and strong resale value.
The Good
The 2021 Kenworth T370 excels in performance with powerful engine options, and its renowned reliability ensures minimal downtime, appealing to practical buyers. Emotionally, the comfortable cab and commanding presence offer pride of ownership. Its efficient operation and strong value proposition make it a smart, long-term investment.
The Bad
While generally robust, potential buyers should watch out for the complexity of advanced electronic systems on some configurations, which can lead to costly repairs. Some older designs might feel less refined compared to newer competitors in terms of cabin ergonomics and noise insulation.

2021 Kenworth T370: Quick Overview
- Engine Options: The 2021 Kenworth T370 typically features the PACCAR PX-7 engine.
- Horsepower: Horsepower for the PACCAR PX-7 engine ranges from approximately 200 hp to 325 hp. Torque figures can reach up to 750 lb-ft.
- Fuel Economy: Specific EPA-estimated fuel economy figures for vocational trucks like the T370 are not readily available as they vary significantly based on application, load, driving conditions, and axle ratios. However, Kenworth trucks are generally designed with efficiency in mind through advanced engine management and aerodynamics.

What Problems Does the 2021 Kenworth T370 Have?
The 2021 Kenworth T370, like most commercial vehicles, has a history of owner reports that can highlight potential issues. Frequently reported problems, though not necessarily widespread for every unit, often center around the PACCAR PX-7 engine. Some owners have experienced issues with the diesel particulate filter (DPF) system requiring regeneration or cleaning more frequently than expected, especially in stop-and-go urban driving conditions. Electrical gremlins, such as intermittent sensor failures or dashboard warning lights, can also be reported, though these are often minor and resolved with software updates or component replacements. Transmission issues, particularly with automatic transmissions, can occasionally arise, though these are typically related to heavy use or improper maintenance.
Recalls for the 2021 Kenworth T370 are periodically issued by the manufacturer and are typically related to safety-critical components. These can include issues with braking systems, steering components, or potential defects in electrical wiring harnesses. It is crucial for owners to stay informed about any active recalls and ensure they are addressed promptly by an authorized Kenworth dealer. Specific model year issues are less common for a single model year like 2021, but trends from previous years, such as early wear on certain suspension components or HVAC system performance in extreme climates, might persist. Long-term reliability is generally considered strong, but like any heavy-duty vehicle, consistent and thorough maintenance is paramount. Neglecting regular service intervals, fluid changes, and inspections can exacerbate minor issues into more significant and costly problems over time, impacting overall durability.
How long will the 2021 Kenworth T370 last?
Based on owner data and typical maintenance habits for vocational trucks, a 2021 Kenworth T370 can reasonably be expected to provide 10-15 years of service or accumulate 300,000 to 500,000 miles, with some units potentially exceeding these figures. Long-term durability is a strong suit for Kenworth, with robust chassis and powertrain components designed for demanding use. However, weaknesses can emerge over time, primarily related to the emissions systems (DPF, SCR) which can require specialized maintenance and potentially costly repairs if neglected. Electrical components and certain seals or hoses may also degrade with age and mileage. Proactive and diligent maintenance, including regular fluid changes, filter replacements, and inspections, is crucial for maximizing its lifespan and minimizing the impact of these potential weaknesses.
What Technology & Safety Features are Included?
The 2021 Kenworth T370 is primarily a workhorse, so its built-in technology, entertainment, and driver-assistance features are focused on functionality and safety rather than luxury or cutting-edge infotainment. Standard technology typically includes essential diagnostics, a basic AM/FM radio with auxiliary input, and a clear, easy-to-read instrument cluster. Power windows and door locks are often standard, enhancing driver convenience.
Optional technology and comfort features can significantly enhance the driving experience. These may include an upgraded infotainment system with Bluetooth connectivity, USB ports, and potentially navigation. For driver comfort during long shifts, options might include enhanced climate control systems, air-ride seats, and improved interior lighting.
Driver-assistance and safety features are a growing area for commercial vehicles. While the 2021 T370 might not offer the same advanced suites found in passenger cars, safety is paramount. Standard safety features include robust braking systems (often air brakes), a strong frame construction, and ample visibility from the driver's seat. Optional safety features can include features like a backup alarm, heated mirrors for inclement weather, and potentially lane departure warning systems or collision mitigation systems, depending on the specific vocational package selected and manufacturer offerings at the time.
Specific crash-test ratings for vocational trucks like the Kenworth T370 are not typically published by organizations like the NHTSA or IIHS in the same way they are for light-duty vehicles. However, Kenworth trucks are designed and built to meet or exceed stringent federal Motor Vehicle Safety Standards (FMVSS) for commercial vehicles, focusing on occupant protection through robust cab structures, seat belt systems, and impact-absorbing designs. The emphasis is on structural integrity and providing a safe working environment for the driver under demanding conditions.
