Analysis

What Problems Does the 2017 International Prostar Have?

Frequently reported problems with the 2017 International Prostar often revolve around the engine's aftertreatment system, particularly issues with the diesel particulate filter (DPF) and diesel exhaust fluid (DEF) systems. These can lead to reduced power and increased downtime. EGR valve failures are also commonly reported. Electrical issues, including sensor malfunctions and wiring problems, are other recurring concerns.
Specific recalls could vary, but it's crucial to check the NHTSA website for any open recalls related to the VIN. Older Prostar models (pre-2015) had some issues related to the MaxxForce engines. These are not relevant to the 2017 model which typically uses Cummins or later Navistar engines. Long-term reliability concerns include potential turbocharger failures, especially if maintenance isn't diligently followed. Rust can also become a problem in regions with harsh winters and road salt. Regular inspections and preventative maintenance are essential to mitigate these issues and extend the lifespan of the truck. Proper DEF fluid usage and adherence to service intervals are also critical to avoiding aftertreatment system problems.

How long will the 2017 International Prostar last?

A 2017 International Prostar, given proper maintenance, can realistically achieve 750,000 to 1,000,000 miles or more. Years of service can easily exceed 10 years, depending on usage. Factors influencing lifespan include adherence to maintenance schedules, driving conditions, and the quality of replacement parts used. Long-term durability hinges on addressing common issues promptly. Weaknesses include potential for corrosion, particularly in areas exposed to road salt, and wear and tear on suspension components. Regular oil changes, filter replacements, and inspections are essential for maximizing longevity. Neglecting maintenance will significantly shorten the lifespan.

What Technology & Safety Features are Included?

The 2017 International Prostar's tech features are generally practical for long-haul trucking. Standard features often include a basic infotainment system with AM/FM radio and Bluetooth connectivity. Some models offered upgraded sound systems and satellite radio. Driver-assistance features were typically optional and could include collision mitigation systems, lane departure warning, and adaptive cruise control. Safety features include standard ABS brakes, traction control, and driver and passenger airbags.
Optional features could also encompass electronic stability control. Some models featured telematics systems for fleet management, providing real-time data on vehicle performance and driver behavior. Crash-test ratings for heavy-duty trucks are not typically conducted by the NHTSA or IIHS in the same manner as passenger vehicles. However, the Prostar is designed with safety in mind, incorporating features to protect occupants in the event of an accident. The focus is more on preventing accidents through driver-assistance technologies and ensuring structural integrity to minimize damage in a collision. Enhanced visibility through large mirrors and well-placed lighting is also a key safety aspect. The interior design prioritizes ergonomics to reduce driver fatigue and improve alertness.

Current used market prices typically range from $30,000 to $70,000, contingent on mileage, condition, and maintenance history. Depreciation is significant for commercial trucks. Factors affecting resale value include engine hours, mileage, maintenance records, overall condition, and any upgrades or modifications. Trucks with well-documented maintenance and lower mileage command higher resale prices. The reputation of the engine and its performance also heavily influence the used market value.

How Does the 2017 International Prostar Compare to Other Truck?

The 2017 International Prostar competes with trucks like the Freightliner Cascadia, Kenworth T680, Peterbilt 579, and Volvo VNL. In terms of performance, the Prostar offers similar engine options and towing capacity. Features-wise, it's generally comparable, though some rivals might offer more advanced technology as standard. Reliability is where the Prostar can sometimes fall short, with some owners reporting more frequent issues than with the Freightliner Cascadia or Volvo VNL.
Price-wise, the Prostar is often competitive, especially on the used market. The Kenworth and Peterbilt often command a premium. For similar reliability and features at a comparable price, the Freightliner Cascadia is a strong alternative. The Volvo VNL also offers a comfortable ride and generally good fuel economy, but may be slightly more expensive to maintain. Ultimately, the best choice depends on individual priorities, such as budget, preferred features, and tolerance for potential maintenance issues. If reliability is paramount, the Freightliner Cascadia or Volvo VNL may be better choices. If budget is the primary concern and you are comfortable with potentially more frequent maintenance, the Prostar remains a viable option.

Final Verdict: Is the 2017 International Prostar a Good Truck?

The 2017 International Prostar is ideal for owner-operators or small fleets looking for a cost-effective solution in the used truck market. It's worth buying if you're prepared to perform regular maintenance and address potential issues promptly. A thorough pre-purchase inspection is crucial. It's generally better to buy a well-maintained used model than to seek a newer, less-reliable option. Specific trims with the Cummins ISX15 engine are often preferred for their balance of power and reliability. The Prostar provides a good value proposition for those prioritizing affordability and willing to invest in upkeep.
