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. However, with proper servicing and timely component replacement, the core structure and powertrain demonstrate remarkable longevity.
What Technology & Safety Features are Included?
The 2018 Kenworth T680 integrates a suite of technologies aimed at enhancing driver comfort, efficiency, and safety. Standard tech features often include a digital driver display providing essential vehicle information, power windows and locks, and a basic HVAC system. The entertainment system typically comprises an AM/FM radio with auxiliary input, with optional upgrades to include a sophisticated infotainment unit. 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. Fuel is a major expenditure, though the T680's efficiency helps mitigate this. Maintenance and repair costs can be high; regular oil changes, filter replacements, and adherence to the PACCAR MX-13 engine service schedule are critical. Major repairs can be costly, especially for engine or transmission components. Overall, while the T680 is designed for efficiency, its long-term ownership costs are considerable due to the nature of heavy-duty trucking, making it a significant investment rather than an economical choice in terms of personal vehicle ownership.
