Analysis
What Problems Does the 2006 Peterbilt 387 Have?
Another common long-term reliability concern revolved around the Diesel Particulate Filter (DPF) system, which was becoming more common. DPFs require regular regeneration cycles to burn off trapped soot, and failures in the DPF or its sensors could lead to "derate" conditions, severely limiting the truck's power. Sensor failures, especially Nox sensors, were also prevalent.
Beyond emissions, other frequently reported problems included electrical gremlins, such as faulty wiring harnesses causing intermittent issues with lights, gauges, or accessory power. Air conditioning systems could also be troublesome, with compressor failures or leaks being relatively common. Some owners reported issues with the Peterbilt Air Trac suspension system, specifically airbag or leveling valve failures over time, requiring consistent inspection. Interior plastics and trim, while initially robust, could suffer from cracking or fading with age and sun exposure. Frame and chassis components generally held up well, but rust on older, high-mileage units, especially in road-salt prevalent regions, could become a concern. Regular maintenance, particularly regarding the engine's cooling and emissions systems, is paramount to mitigating these known issues and ensuring long-term reliability for a 2006 Peterbilt 387.
How long will the 2006 Peterbilt 387 last?
What Technology & Safety Features are Included?
Built-in Tech & Entertainment: Standard tech included basic analog gauges for engine vital signs (oil pressure, water temperature, RPM, speed), an odometer, and trip meters. Digital displays were minimal, often limited to small LCD readouts for things like outside temperature or basic diagnostics. Entertainment typically comprised an AM/FM stereo with CD player, often from a third-party supplier like Panasonic or Kenwood. Optional upgrades might have included more advanced stereo units with auxiliary inputs, or even rudimentary satellite radio systems if selected. The sleeper cabs offered 12V power outlets for charging personal electronics and provisions for installing CB radios and televisions, which were considered high-tech amenities for drivers spending extended periods on the road.
Driver-Assistance Features: True driver-assistance systems as we know them today (e.g., adaptive cruise control, lane keeping assist, automated emergency braking) were virtually nonexistent in 2006. The 387 offered fundamental assistance features such as standard cruise control for highway driving, power steering for reduced effort, and air-ride seats and suspension to mitigate driver fatigue. Driver vigilance was primarily supported by manual operations and basic warning lights for low air pressure, high engine temperature, or charging system issues.
Safety Features: Safety features were predominantly passive. These included a robust steel cab structure designed to offer protection in the event of an accident, a comprehensive air braking system (ABS was standard), and effective halogen headlights for visibility. Large mirrors with convex sections were standard for improved situational awareness. Some trucks might have had optional heated mirrors or power mirror adjustments. However, active safety technologies like electronic stability control (ESC) were not standard across the board for Class 8 trucks until later years. Airbags for the driver and passenger, common in passenger vehicles, were not standard in most heavy-duty trucks of this era, including the 387, due to differing crash dynamics and design priorities.
Crash-Test Ratings: Independent crash-test ratings, akin to those performed by organizations like the NHTSA or IIHS for passenger cars, are not conducted for heavy-duty commercial trucks like the Peterbilt 387. Manufacturers perform internal testing to meet federal safety regulations (FMVSS/CMVSS), but public consumer-oriented crash-test data is unavailable for these types of vehicles.
