What Problems Does the 2017 International Prostar LF627 Have?

The 2017 International Prostar LF627, like many heavy-duty vocational trucks, can present a range of issues that owners and fleet managers should be aware of. One of the most frequently cited areas of concern revolves around the complex diesel emissions control systems (DEF/SCR systems). Problems can include clogged filters, faulty sensors, or issues with the DEF pump, leading to reduced engine performance and potential downtime. These systems, while crucial for compliance, can be a significant source of repair costs and require meticulous maintenance.

Another area where owners have reported issues is with the electrical system. Gremlins can manifest as intermittent warning lights, issues with dashboard components, or problems with power windows and locks. These can be particularly frustrating and time-consuming to diagnose and repair in a commercial setting.
