The 2017 Kenworth T800 is generally lauded for its robust engineering and long-term reliability, a hallmark of the Kenworth brand. However, like any heavy-duty truck, especially those used in demanding vocational applications, certain areas may require attention over time.
One common area of concern across many heavy-duty diesel trucks of this era, including the T800, relates to the emissions control systems. Issues with the Diesel Particulate Filter (DPF) regeneration, Exhaust Gas Recirculation (EGR) systems, and Selective Catalytic Reduction (SCR) components can arise due to soot buildup, sensor failures, or component wear. These can lead to reduced performance, check engine lights, and costly repairs if not maintained properly.
Electrical gremlins can also manifest in older trucks. This could include issues with dashboard warning lights, sensor malfunctions, or problems with the vehicle's wiring harness, particularly in areas exposed to vibration, moisture, or heat.
For trucks used in construction or off-road environments, suspension and chassis components are subject to increased stress. This can lead to wear on bushings, shock absorbers, and leaf springs. Frame cracks, though rare on well-maintained T800s, are also a possibility on heavily worked units.
While specific recalls for the 2017 model year might be limited, it's always advisable to check for any manufacturer-issued Technical Service Bulletins (TSBs) or recalls that may apply. These often address common wear items or design improvements.
In terms of long-term reliability, the PACCAR MX-13 and Cummins ISX15 engines are known for their longevity when subjected to regular and proper maintenance. However, these are complex engines, and components like turbochargers, fuel injectors, and engine control modules can eventually require servicing or replacement.
Overall, the T800's reputation for reliability is strong, but vigilance regarding emissions systems, electrical integrity, and heavy-duty component wear is essential for owners to maximize its lifespan and minimize unexpected downtime.
