What Problems Does the 2016 Kenworth T680 Have?

  • Frequently Reported Problems:
    • Emissions System Issues: Like many modern diesel trucks, the 2016 T680 can experience problems with its Diesel Particulate Filter (DPF), Selective Catalytic Reduction (SCR), and Diesel Exhaust Fluid (DEF) systems. These issues often lead to "derates" (reduced engine power) and expensive repairs. Sensors within the DEF system, DPF regeneration cycles, and DEF quality can be common culprits, requiring significant attention and cost.
    • Electrical System Glitches: Owners have reported issues with various electrical components, including dashboard warnings, sensor failures, lighting problems, and power accessory malfunctions. These can sometimes be intermittent and difficult to diagnose, leading to frustrating downtime.
    • PACCAR MX-13 Engine Specific Concerns: While generally reliable, some PACCAR MX-13 engines have experienced issues with turbochargers, EGR coolers, or fuel system components. These are often component-specific rather than a widespread design flaw, and by 2016, many earlier iterations' issues had been addressed.
    • HVAC System Problems: Air conditioning and heating failures, especially in the sleeper unit, are occasionally reported. This can range from refrigerant leaks to blower motor issues, impacting driver comfort.
    • Brake System Sensors: Issues with ABS sensors or other brake system components can sometimes trigger warning lights, requiring diagnostic attention.
  • Recalls (2016 Model Year Specific, general search):
    National Highway Traffic Safety Administration (NHTSA) records show several recalls that impacted the 2016 T680, reflecting common heavy truck concerns:
    • Brake System Concerns: Potential issues with air brake lines or valves that could reduce braking effectiveness.
    • Steering System Components: Recalls related to steering shaft fasteners or other components that could affect steering control.
    • Electrical System: Wiring harness issues or potential fire hazards related to specific electrical components.
    • Air Tank Issues: Some recalls have involved air tanks that might not meet specifications, potentially leading to ruptures.
    It's crucial for any prospective buyer to check the specific VIN against NHTSA's recall database to ensure all applicable recalls have been addressed for safety and compliance.
  • Long-Term Reliability Concerns: The T680 is built for durability, but long-term reliability hinges heavily on rigorous maintenance. Emissions components remain the most significant long-term cost and potential headache. Chassis and driveline components are generally robust but require routine inspection and lubrication. Frame cracking is rare but can occur under severe conditions or neglected maintenance over millions of miles.

How long will the 2016 Kenworth T680 last?

The 2016 Kenworth T680, when properly maintained, can typically achieve impressive mileage and years of service. Many owner-operators and fleets report these trucks comfortably exceeding 750,000 to 1,000,000 miles, with some well-maintained units pushing even further. An average life expectancy for a Class 8 truck in long-haul service is often 7-10 years before major overhauls or replacement, though many remain in service longer. The frame, cab structure, and major drivetrain components are generally very robust, contributing to excellent long-term durability. However, emissions system components (DPF, SCR, DEF pumps/sensors) are prone to failure and costly replacement as mileage accumulates, representing a key long-term weakness. Wear and tear on suspension components, steering linkages, and electrical connections are also common over time. Preventative maintenance is critical to achieving maximum lifespan and minimizing expensive unscheduled downtime.

    • Kenworth NavPlus System: A prominent integrated touch-screen infotainment system was a key feature. It offered navigation specifically designed for heavy-duty trucks (truck-specific routing with height/weight restrictions), Bluetooth connectivity for hands-free calling and audio streaming, and a premium audio system. In some configurations, it integrated vehicle diagnostics and fleet management tools.
    • Driver Information Center: A high-resolution digital display in the gauge cluster provided critical operational data, trip information, diagnostic alerts, and performance metrics to the driver in an easy-to-read format.
    • Power Outlets: Multiple 12V and optional 110V power outlets were available throughout the cab and sleeper for charging and operating electronic devices.
    • Premium Sound: Options often included enhanced audio systems with multiple speakers and subwoofers for a superior entertainment experience in the sleeper area.
    • Telematics Integration: The T680 supported various third-party telematics and fleet management systems for tracking, diagnostics, and communication.
  • Driver-Assistance Features (Optional/Emerging):
    While not as pervasive as in passenger vehicles, the 2016 T680 offered some Advanced Driver-Assistance Systems (ADAS) as optional extras:
    • Bendix Wingman Advanced: This radar-based system included features like adaptive cruise control with braking and collision mitigation technology (forward collision warning and automatic emergency braking) to help prevent or lessen the severity of rear-end collisions.
    • Lane Departure Warning: Some models could be equipped with systems that alert the driver with audible or haptic feedback if the truck unintentionally drifts out of its lane.
    • Tire Pressure Monitoring System (TPMS): Available to monitor tire pressures, improving safety by preventing blowouts and enhancing fuel efficiency.
    • Electronic Stability Control (ESC): A standard safety feature designed to help prevent rollovers and maintain control during evasive maneuvers by automatically applying brakes to individual wheels.
  • Safety Features:
    • Robust Cab Construction: Kenworth cabs are built to meet or exceed stringent industry safety standards for structural integrity and occupant protection in the event of an impact.
    • Air Brakes with ABS: Standard anti-lock braking system ensures controlled stopping performance, especially under adverse conditions.
    • Daytime Running Lights (DRL): Enhancing the truck's visibility to other road users.
    • Large Mirrors: Providing excellent visibility around the truck and trailer, often with heated and powered adjustments.
    • Airbag Availability: While not as common as in passenger cars for Class 8 trucks, some configurations might offer driver-side airbags, though this was less prevalent in 2016 for this class.
  • Crash-Test Ratings: Independent crash-test ratings (like those from NHTSA or IIHS for passenger vehicles) are not typically conducted or published for Class 8 heavy-duty trucks like the Kenworth T680. Safety is primarily assessed through compliance with federal motor vehicle safety standards (FMVSS) and manufacturer internal testing for structural integrity and brake performance.

2016 Kenworth T680 Insurance

Insurance for a 2016 Kenworth T680 is moderately priced, reflecting its status as a Truck with strong safety ratings and
reasonable repair costs.

How Does the 2016 Kenworth T680 Compare to Other Truck?

The 2016 Kenworth T680 competes fiercely in the Class 8 aerodynamic highway truck segment, primarily against strong rivals like the Freightliner Cascadia, Peterbilt 579, and Volvo VNL.

  • Performance: The T680, especially when equipped with the Cummins ISX15 or PACCAR MX-13 engine, offers robust performance suitable for diverse hauling needs. It generally matches or slightly edges out rivals like the Peterbilt 579 (its PACCAR sibling) in terms of powertrain breadth. Freightliner Cascadia offers similar Cummins and Detroit Diesel options, often providing competitive power and torque. Volvo VNL is typically paired with Volvo D13 engines, known for integrated powertrain optimization.
  • Features: Kenworth is renowned for its driver-centric cabins. The T680's interior, particularly with the 76-inch high-roof sleeper and Diamond VIT trim, is often considered more premium, spacious, and quieter than a comparably equipped Freightliner Cascadia or even the Volvo VNL. The Peterbilt 579 offers a very similar interior experience due to shared platform elements. Kenworth's NavPlus system was competitive for its time, though all rivals offered similar infotainment and telematics integrations.
  • Reliability: The T680 is considered a very reliable truck when maintained diligently. Its Cummins ISX15 option is a proven workhorse. The PACCAR MX-13, by 2016, had largely matured, though emissions systems remain a common pain point across *all* modern heavy truck brands. Freightliner Cascadias are ubiquitous and generally reliable but can suffer from similar emissions and electrical issues. Volvo VNLs are known for their integrated powertrain reliability but can have unique diagnostic challenges. Peterbilt 579s share much with the T680, so reliability is highly comparable.
  • Price: New, the Kenworth T680 often commanded a slightly higher price point than a similarly specified Freightliner Cascadia, aligning more closely with the premium positioning of Peterbilt. Used, this trend continues, with the T680 often holding its value better than a Cascadia, and on par with the 579. Volvo VNLs can be found at competitive used prices.
Recommendations:
  • Similar Alternatives: The 2016 Peterbilt 579 is an almost identical twin in many mechanical aspects, offering a very similar ownership experience with a slightly different aesthetic. Both are excellent choices for long-haul.
  • Competitive Alternatives:
    • 2016 Freightliner Cascadia Evolution: If initial acquisition budget is a primary concern and a massive service support network is desired, the Cascadia offers a highly capable and efficient package at often lower acquisition costs (new and used).
    • 2016 Volvo VNL: Known for its integrated powertrain (Volvo engine, I-Shift AMT) and strong safety features, it's a compelling choice, especially if looking for a truck optimized for specific routes or requiring a comfortable, quiet cab.
The T680 ultimately stands out for its excellent balance of aerodynamics, driver comfort, and perceived quality, making it a strong contender and often a preferred choice for discerning owner-operators.

Final Verdict: Is the 2016 Kenworth T680 a Good Truck?

The 2016 Kenworth T680 is an excellent choice for long-haul owner-operators and fleets prioritizing driver comfort, fuel efficiency, and a premium brand image. It's ideal for those who spend extensive time on the road, appreciating its spacious, well-appointed sleepers and ergonomic design, which can significantly reduce driver fatigue.

Is it worth buying? Absolutely, especially as a used truck. The significant initial depreciation has already occurred, offering substantial value. A used 2016 T680 with a documented, comprehensive maintenance history (preferably with either a PACCAR MX-13 or Cummins ISX15 engine and an Automated Manual Transmission) provides a durable, comfortable, and efficient platform.

Conditions for buying: Look for units with verifiable service records. A thorough pre-purchase inspection by a reputable heavy-duty mechanic is non-negotiable, with particular attention paid to the condition and operational status of the complex emissions systems. Opt for 76-inch sleeper trims (mid-roof or high-roof) for maximum driver comfort and living space. While ownership costs are inherently high for a Class 8 truck, for a professional driver, the T680's operational efficiency and driver satisfaction can outweigh the expense, making it a wise investment if well-maintained.
