What Problems Does the 2015 Mack GU713 Have?
The 2015 Mack GU713, being a workhorse truck, tends to have reported issues that are often related to its demanding operational environment rather than inherent design flaws. One common area of concern across many heavy-duty trucks, including Mack models from this era, can be related to the Emissions Control Systems. Diesel Particulate Filters (DPFs) and Selective Catalytic Reduction (SCR) systems can sometimes require maintenance or experience clogging, especially if the truck is used for frequent short trips or operates in conditions that don't allow for proper regeneration cycles. This can lead to dashboard warning lights and reduced engine performance.
Electrical System Gremlins are also sometimes reported. This can manifest in various ways, from intermittent dashboard warning lights to issues with lighting or auxiliary systems. The complexity of modern truck electrical systems means that identifying and resolving these issues can sometimes be time-consuming and require specialized diagnostic tools.
Transmission Issues, while not universally prevalent, can occur. Depending on the transmission type (e.g., manual, automated manual, or automatic) and how it has been operated and maintained, owners might experience issues with shifting, clutch wear, or internal component failures, particularly in trucks that have seen heavy hauling or aggressive use.
Suspension and Drivetrain Components, due to constant stress and heavy loads, are also areas that require regular inspection and maintenance. While designed for durability, components like U-joints, leaf springs, and air suspension bags can eventually wear out and require replacement. Specifically for the 2015 model year, it's worth checking for any specific technical service bulletins (TSBs) or recalls that may have been issued by Mack Trucks concerning known issues that were addressed through factory updates or recommended maintenance.
Long-term reliability for the GU713 is generally considered very good, provided it has been meticulously maintained with regular oil changes, filter replacements, and component checks. The robust build quality of Mack trucks is a significant factor in their longevity. However, neglect in maintenance, especially concerning the powertrain and emissions systems, can accelerate wear and lead to more costly repairs over time. Owners should also be aware of potential issues with turbochargers and fuel injection systems, which are critical components in high-horsepower diesel engines.
