What Problems Does the 2020 International LT625 Have?

For the 2020 International LT625, common frequently reported problems often revolve around the complexity of modern emissions control systems, specifically the Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR) systems. Owners have reported issues with DPF regeneration cycles, sensor failures (e.g., NOx sensors), and DEF (Diesel Exhaust Fluid) quality or consumption issues, leading to derates and costly repairs. These are not unique to International but are prevalent across all manufacturers of this era.

Another area of concern, particularly with the early LT series models (including 2020), involved software glitches and electrical system anomalies. These could manifest as incorrect gauge readings, intermittent warning lights, or issues with the infotainment system. While many of these were addressed with software updates, they could be frustrating for operators in the field.

Recalls for the 2020 International LT625 and the broader LT series have included various issues. Examples might involve potential steering shaft fasteners that could loosen, leading to steering loss; issues with brake components; or, in some cases, concerns related to fuel system components. It's crucial for potential buyers of a used 2020 model to check the VIN against NHTSA's recall database to ensure all applicable recalls have been addressed.

Long-term reliability concerns typically center on the durability of the DPF/SCR systems over extended mileage and the maintenance costs associated with them. The Navistar A26 engine, while generally reliable, has faced scrutiny over its long-term performance compared to the more established Cummins X15, though significant issues are not widespread. Attention to preventative maintenance, especially regarding fluids and filters, is paramount for the longevity of both engine types and the overall emissions system. Over time, expect wear and tear on suspension components, air system leaks, and interior wear commensurate with high-mileage commercial use.

How long will the 2020 International LT625 last?

A well-maintained 2020 International LT625 can realistically achieve average mileage of 800,000 to over 1.2 million miles, with a service life ranging from 7 to 12+ years in active commercial use. Owner data suggests that consistent preventative maintenance, especially strict adherence to engine oil, filter, and DEF system service intervals, is critical. Trucks that see lighter loads and consistent highway driving often exceed these averages.

Long-term durability is generally strong, particularly for the Cummins X15 engine. The Navistar A26 has also proven reliable but might require more vigilant attention to its emissions system. Over time, weaknesses tend to emerge in electrical connections (corrosion, wear), air system components (leaks in lines, air dryers), and wear items like suspension bushings and fifth-wheel components. The interior, while durable, will show wear in high-traffic areas. The key to maximizing service life is proactive maintenance, promptly addressing minor issues before they escalate into major failures, particularly concerning the DPF/SCR system.
