The T370, as a Class 7 truck, is designed for significant hauling duties, with Gross Vehicle Weight Ratings (GVWR) often ranging up to 33,000 lbs or more. This translates to substantial towing capabilities, often exceeding 20,000 lbs for suitable trailer setups.
  • Trim-Level Features: Kenworth T370 configurations focus on vocational needs rather than traditional passenger car trim levels. Key features often include:
    • Cab Options: Standard day cabs are common, with options for extended or flat-top roofs for additional storage or driver comfort on longer routes.
    • Suspension: Various suspension options are available, including spring and air-ride suspensions, to suit different load requirements and ride quality preferences.
    • Axles and Drivetrain: A wide array of axle configurations and rear axle ratios are offered to match specific operational demands, from local delivery to heavier hauling.
    • Interior Options: While designed for function, interiors often include comfortable seating, ergonomic controls, clear instrumentation, and options for air conditioning, power windows, and basic sound systems.
    • Chassis Configurations: Available in various wheelbase lengths and cab-to-axle dimensions to accommodate a wide range of body types, from dump bodies and service bodies to box trucks and tractor units.

What Problems Does the 2020 Kenworth T370 Have?

The 2020 Kenworth T370 generally enjoys a reputation for solid reliability, characteristic of the Kenworth brand. However, like any complex vehicle, some common areas of attention or concern can arise over time. Frequently reported issues, though not necessarily widespread for the 2020 model year specifically, often revolve around the exhaust after-treatment system (DEF system), which can sometimes encounter sensor failures or clogging, particularly with inconsistent usage or poor fuel quality. Drivers have occasionally noted issues with the diesel particulate filter (DPF) regeneration cycles if the truck isn't operated in conditions that allow for proper self-cleaning. Electrical system glitches, while infrequent, can sometimes manifest as intermittent warning lights or issues with auxiliary systems. For the 2020 model year, specific widespread recalls are not extensively documented as major systemic failures. However, commercial vehicles are subject to periodic recalls that can affect various components, from braking systems to emissions controls, depending on manufacturer bulletins. Owners should always consult the NHTSA database or their dealer for any applicable recalls. Long-term reliability is generally excellent, provided routine maintenance is adhered to. The PACCAR PX-7 engine is a proven powerplant, but like all diesels, it requires proper care, including timely oil changes with the correct specification oil and filter, and ensuring the cooling system is maintained. Issues that might emerge after extensive mileage could include wear and tear on the suspension components, brake wear, and potentially driveline issues if subjected to extreme workloads without adequate preventative maintenance. The focus for long-term durability lies heavily on how the vehicle is operated and maintained, with a strong emphasis on scheduled service intervals for optimal performance and longevity.

How long will the 2020 Kenworth T370 last?

The 2020 Kenworth T370 is built for longevity, and with diligent maintenance, it's common for these trucks to serve for 15 to 20 years, accumulating well over 500,000 miles, with some reaching closer to 1,000,000 miles in lighter-duty vocational roles. Owner data suggests that regular oil changes, fluid checks, and addressing minor issues promptly are crucial. The PACCAR PX-7 engine is robust, but like any diesel, its long-term health depends on consistent regeneration cycles and clean fuel. Weaknesses over time tend to be related to wear and tear on components such as suspension bushings, brake pads, and exhaust system connections, especially in corrosive environments. However, the core chassis and drivetrain are designed for demanding, extended service life, making the T370 a highly durable investment when properly cared for.

What Technology & Safety Features are Included?

The 2020 Kenworth T370, being a vocational truck, prioritizes functionality and driver focus over cutting-edge consumer-grade technology. The built-in tech is geared towards operational efficiency and driver awareness. Standard entertainment features often include a digital AM/FM radio with auxiliary input and possibly USB connectivity. Higher-spec options might introduce Bluetooth for hands-free calling and audio streaming, and perhaps a more advanced infotainment display. Driver-assistance features are less common in the traditional automotive sense, but Kenworth emphasizes visibility and ease of operation. Features like large, adjustable mirrors are standard, contributing to driver safety. Optional additions could include backup cameras for enhanced maneuverability in tight spaces. Safety features are robust and focus on the structural integrity and operational safety of a heavy-duty vehicle. This includes standard anti-lock braking systems (ABS) for controlled stopping. Air brakes are a common feature for effective braking power. The cab structure is engineered to withstand significant forces, offering protection to the occupants. Kenworth trucks are not subjected to typical passenger car crash-test ratings from organizations like the IIHS or NHTSA. Instead, their safety is evaluated based on industry standards for commercial vehicle construction, durability, and specific safety regulations applicable to heavy-duty trucks. Rollover protection, occupant restraint systems, and the overall strength of the chassis and cab are paramount. While advanced driver-assistance systems (ADAS) like adaptive cruise control or lane-keeping assist are generally not standard or widely available on the T370, the focus is on providing a stable, controllable, and visible platform for the driver to operate safely in demanding vocational environments. The emphasis is on practical safety and visibility rather than automated systems.
