What Problems Does the 2014 Peterbilt 579 Have?
For the 2014 Peterbilt 579, frequently reported problems largely center around the complex emission control systems of that era. Both the PACCAR MX-13 and Cummins ISX15 engines were subject to issues with the Diesel Particulate Filter (DPF), Diesel Exhaust Fluid (DEF) system, and Exhaust Gas Recirculation (EGR) system.
One prevalent issue involves the DPF system, prone to clogging, requiring frequent regenerations, or expensive replacements. Sensors associated with the DPF, such as differential pressure sensors, are also common failure points, often leading to engine derates and "check engine" lights.
The DEF system frequently experiences problems with DEF pump failures, quality sensor malfunctions, and crystallization within the tank or lines, especially in cold weather. These issues directly impair the Selective Catalytic Reduction (SCR) system's function, resulting in engine derates and significant downtime.
EGR coolers and valves are also known trouble spots. Leaking EGR coolers can cause coolant loss, while faulty EGR valves can affect engine performance and fuel efficiency.
Electrical issues, though not exclusive to the 579, are also reported, ranging from minor sensor failures and dash lighting glitches to more complex wiring harness problems that are challenging to diagnose.
Regarding recalls, like most heavy trucks, the 2014 Peterbilt 579 has had various recalls, often addressing safety-related components, specific engine or transmission parts, or emissions system defects. Owners should always verify open recalls via the NHTSA website or a Peterbilt dealership using their VIN.
Long-term reliability concerns typically revolve around the lifespan and operational costs of these emission components. While the core engine and drivetrain are generally robust, the ancillary emission systems often require substantial maintenance, repair, or replacement once the truck accumulates high mileage (e.g., 500,000 to 800,000 miles). Interior trim durability can also become a minor concern after extensive use.

reasonable repair costs.
How Does the 2014 Peterbilt 579 Compare to Other Truck?
The 2014 Peterbilt 579 faced strong competition from rivals such as the Freightliner Cascadia, Kenworth T680, Volvo VNL, and International ProStar.
Performance: The 579, equipped with PACCAR MX-13 or Cummins ISX15 engines (400-550 HP), delivered comparable performance to its contemporaries. Freightliner's Detroit Diesel DD13/DD15, Kenworth's shared MX-13/ISX15, Volvo's D13, and International's MaxxForce/ISX all offered similar pulling power for standard 80,000 lbs GCW operations.
Features: Peterbilt positioned the 579 as a premium, aerodynamic truck. Its interior, particularly with upgraded trim, often felt more luxurious and driver-centric than a base Cascadia or ProStar, rivaling the Kenworth T680 in comfort and amenities. The optional SmartNav system provided integrated tech. However, advanced driver-assistance systems were rudimentary across all brands in 2014, with stability control and ABS being common safety features.
Reliability: For 2014, all manufacturers grappled with the reliability of post-2010 emissions systems (DPF, DEF, EGR). While the 579's core drivetrain components were generally robust, emissions systems were a widespread Achilles' heel across the industry. The Kenworth T680, being a platform mate, shared very similar reliability characteristics. Freightliner and Volvo also faced their own emission-related challenges. International's MaxxForce engines of earlier years had more significant reliability concerns, though Cummins ISX options improved their standing.
Price: New, the 579 was positioned as a premium offering, priced similarly to the Kenworth T680 and Volvo VNL, often higher than base Freightliner Cascadias or International ProStars. This premium brand perception generally translates to slightly better resale value for Peterbilts and Kenworths in the used market, assuming comparable condition and mileage.
Alternatives:

This premium brand perception generally translates to slightly better resale value for Peterbilts and Kenworths in the used market, assuming comparable condition and mileage.
Alternatives:
- Similar Alternatives: The 2014 Kenworth T680 is virtually identical in many respects, sharing engines and fundamental architecture, making it the most direct and comparable alternative. The 2014 Volvo VNL is also a strong competitor, especially known for its comfortable cab and integrated powertrain.
- Potentially Better Alternatives (depending on specific needs): If the lowest acquisition cost is paramount, a 2014 Freightliner Cascadia could be a "better" option due to generally lower new and used pricing, often making it a fleet favorite. However, "better" is subjective and depends on specific operational requirements, driver preferences, and the perceived long-term total cost of ownership, especially concerning emission system maintenance.
Final Verdict: Is the 2014 Peterbilt 579 a Good Truck?
The 2014 Peterbilt 579 is an excellent choice for owner-operators and small to medium-sized fleets prioritizing driver comfort, aerodynamic efficiency, and the prestigious Peterbilt brand for long-haul operations. It appeals to those seeking a comfortable "home on the road" and an image of professionalism.
Is it worth buying? Yes, but with crucial conditions. As a used vehicle, it offers significant value due to substantial depreciation from its new price. However, buyers must be financially prepared for potential maintenance and repair costs, particularly concerning its 2014-era DPF, DEF, and EGR emission systems.
When considering a purchase, target a used 2014 Peterbilt 579 with a verifiable, meticulous maintenance history. Prioritize models that have either had recent major emission system overhauls or engine "in-frames," as these address the most common and costly long-term vulnerabilities. A thorough pre-purchase inspection by a specialized heavy-duty mechanic is non-negotiable. Trims offering larger sleepers provide superior driver amenities. For those who can budget for these potential expenses and find a well-cared-for example, the 579 remains a solid, dependable workhorse with strong driver appeal and decent resale potential.
