What Problems Does the 2008 Peterbilt 365 Have?
The 2008 Peterbilt 365, like many heavy-duty trucks from its era, entered the market during a significant transition in emission regulations, which often became a source of frequently reported problems and long-term reliability concerns. For the 2008 model year, the primary concern revolved around the early implementations of the EPA's 2007 emission standards, specifically the Diesel Particulate Filter (DPF) and Exhaust Gas Recirculation (EGR) systems. These systems were designed to reduce emissions but often proved problematic, leading to:
Recalls for the 2008 Peterbilt 365 would typically be engine-specific (issued by Cummins or Caterpillar for their components) or related to chassis components (e.g., brake systems, steering linkages) rather than specific to the 365 model itself. Owners considering a 2008 Peterbilt 365 should thoroughly review maintenance records, specifically looking for evidence of DPF/EGR system overhauls or removals (if permitted) and regular service. The longevity of these trucks is high, but the cost of maintaining the emission systems can be a significant factor in long-term reliability and ownership costs.
- DPF Regeneration Issues: Clogging of the DPF was common, particularly in vocational applications involving frequent idling or short-haul operations. This led to frequent "regen" cycles, reduced power, or even derates. Sensors related to the DPF (delta pressure, temperature) were also known to fail.
- EGR Valve and Cooler Problems: The EGR system, responsible for recirculating exhaust gases, was susceptible to soot buildup, causing valves to stick or coolers to clog and even leak, potentially leading to engine damage.
- Turbocharger Failures: The increased back pressure from the DPF and the demands of the EGR system could put additional stress on turbochargers, leading to premature wear or failure.
- Fuel Injector and Fuel System Issues: The high-pressure common rail fuel systems, while efficient, could be sensitive to fuel quality, leading to injector issues or pump failures, which are costly repairs.
- Electrical System Gremlins: Wiring harness issues, sensor failures, and problems with the Electronic Control Module (ECM) could cause a variety of intermittent performance problems or diagnostic challenges.
- Cooling System Leaks: Radiator and hose failures are common on high-mileage trucks, and the 365 was no exception, especially under demanding vocational use.
- Suspension and Steering Component Wear: Due to their heavy-duty applications, components like kingpins, tie rods, drag links, and leaf springs/airbags would experience wear over time and require regular inspection and replacement, though this is typical for vocational trucks.
