What Problems Does the 2012 Kenworth T800 Have?
The 2012 Kenworth T800 is generally recognized for its robust build and long-term reliability, a hallmark of Kenworth trucks. However, like any heavy-duty vehicle, certain issues can arise over time and with mileage.
Frequently reported concerns often revolve around the powertrain and its associated components. For this model year, owners have sometimes reported issues with diesel particulate filters (DPFs) requiring regeneration or cleaning more frequently, especially if the truck is used for a lot of short-haul or stop-and-go driving. Exhaust gas recirculation (EGR) systems can also be a source of problems, leading to reduced power and increased emissions if they become clogged or malfunction.
Electrical issues are another area where owners might encounter problems. While not specific to the 2012 model year, older trucks can experience issues with wiring harnesses becoming brittle or connections corroding over time, leading to intermittent faults in various systems like lighting, gauges, or engine controls. The complex electronic control modules (ECMs) can also be a point of failure, though this is less common.
Suspension components, such as leaf springs, bushings, and shock absorbers, can wear out over time due to the demanding nature of vocational applications and heavy loads. Premature wear on these parts could lead to a rougher ride and affect handling. The clutch and transmission, particularly in manual transmission models, will naturally experience wear with high mileage and demanding use, requiring eventual replacement.
Recalls for the 2012 Kenworth T800 are typically managed by PACCAR, Kenworth's parent company. These recalls are usually related to specific component failures or safety concerns identified during manufacturing or by fleet operators. Common recall areas might include braking system components, steering linkages, or certain engine or transmission parts. Owners should always check the NHTSA website or contact a Kenworth dealer with their VIN to determine if any recalls apply to their specific vehicle.
Long-term reliability is generally excellent if the T800 is properly maintained with regular oil changes, filter replacements, and component inspections. Neglecting preventative maintenance is the quickest way to exacerbate potential issues and reduce the overall lifespan and reliability of the vehicle. The core chassis and frame are incredibly durable, but auxiliary systems and wear items will require attention as the miles accumulate.
