What Problems Does the 2018 Kenworth T370 Have?

The 2018 Kenworth T370, like many heavy-duty trucks, is generally built for longevity and reliability. However, common areas that owners and technicians report attention needed over time, particularly with the PACCAR PX-7 engine, include the Diesel Particulate Filter (DPF) system. Issues such as clogging, regeneration failures, or sensor malfunctions can arise, especially if the truck is used for frequent short trips or has incomplete regeneration cycles. These can lead to reduced performance, increased fuel consumption, and potential costly repairs.

Another area to monitor is the exhaust gas recirculation (EGR) system, which can also become clogged with soot over time, impacting engine performance. Fuel system components, such as injectors and the high-pressure fuel pump, are critical and can be sensitive to fuel quality. While not specific to the 2018 model year, any heavy-duty diesel can experience wear and tear on its transmission, particularly with heavy use, and maintenance is key.

Electrical system issues, though less frequent, can manifest as sensor failures or intermittent warning lights. It's important to note that many of these potential issues are not unique to the 2018 T370 but are characteristic of modern diesel engines and heavy-duty vehicles in general. Regular and diligent maintenance, adhering to the manufacturer's service intervals, and addressing minor issues promptly are crucial for mitigating long-term reliability concerns.

Recalls for a 2018 Kenworth T370 would be manufacturer-specific and would typically involve safety-related components. Owners should always check with Kenworth or the National Highway Traffic Safety Administration (NHTSA) for any outstanding recalls applicable to their specific VIN. For instance, a recall could be related to braking systems, steering components, or electrical wiring harnesses.

Long-term reliability is largely dependent on how the truck is used and maintained. A T370 used in constant, heavy-duty vocational service with proper maintenance will likely prove very durable. Conversely, a unit used sporadically or without adequate servicing might encounter more issues. The robust chassis and PACCAR powertrain are generally considered strong points for longevity.

How long will the 2018 Kenworth T370 last?

The 2018 Kenworth T370 is engineered for commercial use, meaning its lifespan is measured in hundreds of thousands of miles, often exceeding 500,000 miles and sometimes reaching over a million miles with meticulous maintenance. Owner data and professional maintenance habits are paramount. Vehicles used for local delivery or moderate vocational tasks, with regular oil changes, filter replacements, and proactive checks of the PACCAR PX-7 engine's emissions systems (DPF, EGR), can last well over a decade. Weaknesses that emerge over time are typically related to the wear and tear of high-mileage components, such as suspension parts, brake systems, and exhaust aftertreatment systems. Engine-related components can also require refurbishment or replacement after significant mileage. However, the fundamental chassis and powertrain are designed for exceptional durability.

What Technology & Safety Features are Included?

The 2018 Kenworth T370, being a vocational truck, prioritizes functionality, durability, and operator safety over advanced consumer-grade technology. Its built-in tech is focused on operational efficiency and driver awareness.
