The 2021 International LT625 is International's flagship Class 8 long-haul tractor, designed for efficiency and driver comfort. Introduced as part of the LT series in 2017, the LT625 configuration focuses on aerodynamic efficiency and driver-centric features. While not having traditional "trims," it offers various sleeper sizes and powertrain options. New pricing typically ranged from $140,000 to over $200,000. It stands out for its spacious, quiet cab and advanced technology aimed at maximizing uptime and reducing total cost of ownership.
The Good
The LT625 offers superior driver comfort with a spacious, quiet cabin and intuitive controls, appealing emotionally to those who live on the road. Practically, its advanced aerodynamics and efficient powertrain options (including the A26 and Cummins X15) deliver excellent fuel economy and robust performance, enhancing uptime and reducing operating costs, making it a strong value proposition for fleets and owner-operators.
The Bad
While significantly improved, some owners report occasional electrical or software glitches. The International A26 engine, despite its advancements, may still carry a perception of past Navistar engine issues for some buyers, warranting a thorough service history review. General DPF/SCR system maintenance requirements are also a common concern across modern diesels.
2021 International LT625: Quick Overview
- Engine Options: The 2021 International LT625 offers two primary engine choices:
- International A26 (12.4L): Navistar's own engine, designed for efficiency and lightweight performance.
- Cummins X15 (15L): A highly respected industry standard, known for its power and reliability.

What Problems Does the 2021 International LT625 Have?
The 2021 International LT625, while a strong contender, has had some frequently reported areas of concern, though often less severe than earlier International models. Common issues generally revolve around the complex emission control systems inherent in all modern diesel trucks.
DPF/SCR System: Like many Class 8 trucks, problems with the Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR) systems are reported. These can include clogged filters, sensor failures, and issues related to Diesel Exhaust Fluid (DEF) quality or injection, often exacerbated by improper maintenance or extended idling. While not unique to International, they represent significant potential repair costs.
Electrical Glitches: Occasional reports of minor electrical gremlins or software bugs within the infotainment system or other electronic components have surfaced. These are often resolved with software updates but can be frustrating. Early LT series models (pre-2020 refresh) saw more frequent reports in this area, but the 2021 model benefited from continuous improvements.
Air System Leaks: Air system components, such as air dryers, valves, and lines, can be sources of leaks over time, leading to reduced air pressure and potential issues with braking or air-ride suspensions.
International A26 Engine: While significantly improved from previous International engines, some owner-operators might still approach the A26 with caution due to the brand's historical engine reliability issues. For the 2021 model year, the A26 is generally considered reliable, but thorough maintenance is crucial to its longevity. Concerns tend to be less about catastrophic failures and more about sensor-related issues or DPF/SCR interactions.
Recalls: For a specific model year like 2021, recalls are often component-specific and vary. These could range from minor wiring harness issues to potential brake system components or even software updates. It's essential for potential buyers to check the VIN for any outstanding recalls through NHTSA or International's service portal. Long-term reliability is largely dependent on rigorous preventative maintenance schedules and driver habits.

How long will the 2021 International LT625 last?
A well-maintained 2021 International LT625, like other Class 8 trucks, is engineered for impressive longevity. With diligent preventative maintenance and responsible driving, these vehicles commonly achieve 1,000,000 to 1,500,000 miles or more over 10 to 15 years of service. Engines like the Cummins X15 are particularly renowned for their robust long-term durability when serviced correctly. The chassis and major structural components are built to last.
However, long-term weaknesses over time typically include wear and tear on suspension components, air system integrity (lines, valves, air dryer), and the inevitable degradation of emissions system components (DPF, SCR) which are costly to replace. Electrical connections and sensors can also become prone to issues with age and exposure. Consistent maintenance is paramount to achieving maximum service life.

2021 International LT625 Prices and Market Value
When new, the 2021 International LT625 typically retailed between $140,000 and $200,000+, varying significantly based on engine choice, sleeper configuration, and optional features. As of mid-2024, a used 2021 model can be found in the range of $70,000 to $120,000+, reflecting substantial depreciation common in the commercial trucking sector. Factors heavily influencing resale value include mileage (lower is always better), engine type (Cummins X15 often commands a premium), maintenance history, overall condition, and market demand for specific configurations (e.g., larger sleepers). The initial rapid depreciation tends to stabilize after 3-5 years, but the used truck market is cyclical and influenced by economic conditions and freight volumes.
2021 International LT625 Cost of Ownership
Owning a 2021 International LT625, like any Class 8 truck, is a very costly endeavor, despite its focus on efficiency. Commercial insurance can range from $10,000 to $20,000+ annually. Fuel is the largest expense, with a typical 6-9 MPG meaning substantial costs for high-mileage operations. Maintenance, including preventative service, tires, and routine wear items, can easily run $0.15-$0.25 per mile. Major repairs (engine, transmission, emissions) are infrequent but extremely expensive. While features aim to reduce Total Cost of Ownership (TCO) through efficiency and uptime, the sheer operational scale makes it inherently expensive to own, balanced by its significant earning potential.
