What are the reasons for the electronic parking failure in Haval H2?
2 Answers
Haval H2 electronic parking failure reasons: Engine fails to start: If the battery is dead, you can use jumper cables or an emergency power source to start the engine. If it still fails to start, it may be due to vehicle circuit or fuel system failure, and it is recommended to send it to a repair shop. Tire punctures, blowouts, and other failures: Replace the spare tire promptly and repair the punctured tire in time. Brake failure: Perform thorough maintenance of the brake system, regularly check the wear level of components such as brake discs and brake pads, and replace them if necessary. During daily driving, try to avoid prolonged braking. If encountering long downhill sections, it is recommended to use lower gears and engine braking to prevent the brake pads from overheating.
As a veteran driver of a Haval H2, I also encountered an electronic parking brake error last year. At that time, a yellow P light illuminated on the dashboard, and the tow hook was already attached. The repair shop found that the guide pins of the rear brake calipers were rusted shut, and mud and debris had jammed the return spring after driving on muddy roads in the rain. The mechanic mentioned that this car's electronic parking brake uses a motor-driven steel cable mechanism, which has average sealing and is particularly prone to dust accumulation. He advised against directly spraying water onto the brake discs when washing the car and recommended disassembling and cleaning it every two years for lubrication. If you hear a 'clicking' noise when engaging the parking brake, it's likely the steel cable getting stuck—address it immediately to avoid burning out the motor, as replacing the actuator module can cost over a thousand. Additionally, worn brake pads can trigger false alarms due to sensor misalignment—all this comes from firsthand experience.
