bj40 diesel version common problems are: transfer case fracture, resonance, abnormal noise, water leakage, oil leakage, and even brake failure. Taking the Beijing BJ40 2021 2.3T manual four-wheel drive Blade Hero Pioneer Edition as an example: it is a compact 4-door 5-seat SUV with a length, width, and height of 4645mm, 1925mm, and 1871mm respectively, a wheelbase of 2745mm, and equipped with a 5-speed manual transmission. The maximum torque of the engine in the Beijing BJ40 2021 2.3T manual four-wheel drive Blade Hero Pioneer Edition is 330 Nm, the maximum power is 155 kW, and the fuel tank capacity is 75L.
I've driven quite a few diesel vehicles including the BJ40, and found several common issues. The diesel engine produces noticeably loud noises during cold starts, sometimes sounding like a tractor, which isn't great for the driving experience. Fuel consumption is also less than ideal, especially in stop-and-go city traffic, where it's significantly higher than the claimed values—likely due to clogged fuel injectors or low turbo efficiency. The DPF (Diesel Particulate Filter) tends to clog easily, leading to reduced power and warning lights, requiring frequent highway driving to clean it out. There are also minor electronic system glitches, such as false sensor alarms, which disrupt normal driving. The suspension is sturdy but too bumpy, making long trips uncomfortable. My advice is to maintain the fuel injectors regularly and check the DPF periodically to avoid breakdowns and delays.
