What Problems Does the 2018 Kenworth T680 Have?
The 2018 Kenworth T680 is generally regarded as a reliable workhorse in the trucking industry. However, like any complex vehicle, it can encounter specific issues. Frequently reported problems tend to revolve around the sophisticated electronic systems. Some owners have reported issues with the diagnostic trouble codes (DTCs) related to the engine control module (ECM) or various sensors, which can sometimes lead to performance derating or check engine lights. The PACCAR MX-13 engine, while robust, has had some reports of EGR cooler failures or issues with the diesel particulate filter (DPF) regeneration system, particularly if maintenance schedules are not strictly adhered to or if the truck is used primarily for short-haul, stop-and-go driving which doesn't allow for proper DPF cycles.
Recalls for the 2018 model year, if any, would typically be issued by the manufacturer and would involve specific safety-related components. It's crucial for owners to check for any open recalls through Kenworth's official channels or the NHTSA website. Long-term reliability concerns often center on the longevity of certain electronic modules, such as the infotainment system or adaptive cruise control sensors, which can be sensitive to vibration and environmental factors over many years of service. Premature wear on certain suspension components or exhaust system parts can also be noted, though this is often dependent on operational conditions and maintenance. Specific to the 2018 model year, there aren't widespread, model-year-specific systemic failures reported, but rather individual component issues that can arise in any heavy-duty truck of this age. Consistent and proactive maintenance, including regular software updates and adherence to the manufacturer's service intervals, is key to mitigating potential long-term issues and ensuring the continued reliability of a 2018 Kenworth T680.

How long will the 2018 Kenworth T680 last?
A 2018 Kenworth T680, with diligent maintenance, is built for high mileage. Owner data and industry standards suggest that these trucks can comfortably achieve well over 500,000 miles, with many exceeding 1 million miles in long-haul applications. Average annual mileage for a full-time commercial truck can range from 80,000 to 120,000 miles, meaning a 2018 model could have accumulated 400,000 to 700,000 miles by now. The long-term durability is a strong suit, primarily due to robust PACCAR engines and a well-engineered chassis. Weaknesses that emerge over time often relate to wear on consumables like brakes, tires, and suspension components, as well as potential electronic module fatigue.

This optional system can feature a touchscreen display, AM/FM/WB radio, USB/Aux inputs, Bluetooth for hands-free calling and audio streaming, and integrated navigation capabilities. For enhanced driver-assistance, Kenworth offered several optional packages. These could include Lane Departure Warning (LDW) systems that alert the driver if the vehicle drifts out of its lane, and Collision Mitigation Systems (CMS) such as Bendix Wingman Fusion, which uses radar and camera data to detect potential collisions and can automatically apply braking if necessary. Adaptive Cruise Control (ACC) was also an option, helping to maintain a set speed and distance from the vehicle ahead, reducing driver fatigue on long hauls.
Safety features are paramount. Standard safety equipment includes anti-lock braking systems (ABS) for improved stability during braking. Optional safety enhancements go further, with features like a digital camera system for improved visibility and advanced lighting options for better nighttime operation. While heavy-duty trucks like the Kenworth T680 are not subjected to the same passenger car crash-test ratings from organizations like NHTSA or IIHS, manufacturers adhere to stringent federal safety standards for commercial vehicles. These standards encompass cab integrity, structural strength, and protection for occupants in various impact scenarios. The T680's design emphasizes driver protection through its robust construction and available advanced driver-assistance systems, which actively work to prevent accidents.

2018 Kenworth T680 Prices and Market Value
When new, a 2018 Kenworth T680 could range from approximately $100,000 for a basic Day Cab configuration to over $150,000 for a fully equipped long-haul sleeper model, depending heavily on engine, transmission, interior options, and brand-new status. Currently, on the used market, a 2018 Kenworth T680 can be found for anywhere between $50,000 and $100,000. Depreciation on heavy-duty trucks is generally slower than for light-duty vehicles, especially for well-maintained models with lower mileage. Factors significantly affecting resale value include: engine hours and mileage, overall condition (both mechanical and cosmetic), maintenance history, presence of advanced technology packages, and the specific configuration (sleeper size, axle ratios). A truck with a comprehensive service record and fewer than 500,000 miles will command a higher price.
2018 Kenworth T680 Cost of Ownership
Owning a 2018 Kenworth T680 involves substantial costs. Insurance premiums for commercial trucks are significant, influenced by the truck's value, the owner's driving record, and the type of cargo transported.

reasonable repair costs.
How Does the 2018 Kenworth T680 Compare to Other Truck?
The 2018 Kenworth T680 competes directly with other top-tier Class 8 trucks, primarily the Peterbilt 579, Freightliner Cascadia, and Volvo VNL series. In terms of performance, the PACCAR MX-13 engine in the T680 is competitive, offering strong power and torque curves comparable to the Freightliner DD15 or Volvo D13 engines. Fuel efficiency is a strong suit for the T680, often matching or exceeding the Cascadia and Peterbilt 579 due to its advanced aerodynamics.
When it comes to features, the T680 is known for its driver-focused interior and spacious sleeper options, rivaling the comfort and amenities offered by the Volvo VNL and Peterbilt 579. The availability of advanced driver-assistance systems (ADAS) on the T680 is on par with what competitors offer, with options like collision mitigation and lane departure warning systems.
Reliability is a subjective measure, but all these premium trucks are engineered for durability. Kenworth, like Peterbilt (also owned by PACCAR), generally has a strong reputation for build quality. Freightliner and Volvo also have robust offerings, though specific component reliability can vary.
Price-wise, the T680 typically sits in the premium segment, comparable to the Peterbilt 579 and Volvo VNL. The Freightliner Cascadia might sometimes offer a slightly lower entry price point, depending on configuration.
Recommendations:

Recommendations:
- Similar Alternatives: The Peterbilt 579 is a very close sibling to the T680, sharing many PACCAR components and design philosophies. It offers a similar blend of performance, efficiency, and driver comfort. The Volvo VNL series is another strong contender, particularly known for its innovative safety features and comfortable ride.
- Slightly Different Focus: The Freightliner Cascadia is a widely popular choice, often praised for its fuel efficiency and broad range of options, and can sometimes be found at a more accessible price point.
Final Verdict: Is the 2018 Kenworth T680 a Good Truck?
The 2018 Kenworth T680 is ideal for owner-operators and fleet managers prioritizing fuel efficiency, driver comfort, and long-term durability in a Class 8 truck. It's an excellent choice for long-haul applications where driver satisfaction and operational costs are critical.
Whether it's worth buying depends heavily on the purchase condition. A well-maintained used 2018 T680, especially one with lower mileage and a solid service history, represents a compelling value proposition. It's significantly more affordable than a new model but retains much of its performance and efficiency.
Buying new might be justified for fleets demanding the latest technology and maximum warranty coverage. However, for most buyers seeking a reliable, efficient, and comfortable long-haul truck, a carefully selected used 2018 Kenworth T680, particularly in a 76-inch sleeper configuration, is a wise investment that offers strong returns through fuel savings and reduced driver turnover.
