The reason for the constant flashing of the 4WD light when switching from 4WD to 2WD in the Haval H5 is: the switching mode requires a transition process. Once the 4WD light turns off, it indicates that the switch has been successfully completed. 4WD stands for four-wheel drive, which refers to the use of a low-ratio transmission to help the vehicle overcome slipping on muddy and snowy roads, similar to driving on off-road, rocky terrain, and undulating hills. In terms of power, the Haval H5 is equipped with a 2.0-liter turbocharged engine, delivering a maximum horsepower of 190 PS, a maximum power of 140 kW, and a maximum torque of 250 Nm, paired with a 6-speed manual transmission.
I've been driving a Haval H5 for several years and encountered the 4WD light flashing issue, which really worried me at the time. Common causes include sensor problems, such as dirty or damaged speed sensors on the front or rear axle, leading to unstable signals and light flashing; it could also be due to loose or short-circuited wiring connectors, a faulty transfer case control module, or electronic system confusion. Once during winter when driving to the mountains for skiing, the light kept flashing non-stop, so I immediately stopped and went to the 4S shop for inspection. They found it was caused by rust on the transfer case contacts. After repairs, everything returned to normal. Never ignore such flashing, especially during off-roading or in rain/snow conditions, as 4WD failure could cause the vehicle to skid—safety first. Regular maintenance and cleaning of chassis dust can prevent many issues. Repairs usually aren't expensive for small part replacements, but timely action is crucial.
