What does parking failure mean?
2 Answers
Parking failure refers to the loss of braking function after the car has stopped. The parking system involves many components and is related to safety issues. If the electronic parking system fails, it is likely due to a problem with the electronic handbrake, worn brake pads, an issue with the electronic system, or a power supply problem with the battery. In such cases, it is necessary to visit a repair shop to read the fault codes with a decoder and then perform repairs based on the fault codes. The electronic parking system serves as a temporary parking function. For example, when stopping at a red light, releasing the brake pedal will activate the automatic parking, which locks the wheels until the accelerator pedal is pressed again. At that point, the electronic parking system will automatically unlock the wheels, and this action is much faster than pressing the electronic handbrake.
Parking failure means the car doesn't stay still when parked and may move or roll away on its own. I remember last year when I took my old car out for a drive, parked on a small slope, and after getting out, I noticed the car was slowly sliding backward. It scared me so much that I immediately jumped back in. Upon inspection, I found it was an issue with the parking brake system—either the handbrake hook wasn't engaged properly or the sensor in the electronic version had failed. This kind of malfunction is quite dangerous, especially in urban areas or parking lots, as it could lead to collisions with other vehicles or pedestrians. Common causes include excessive wear on brake pads, aging wires with poor contact, or software defects in the system. For example, some cars' electronic components are prone to short circuits in humid weather. If you notice such a problem, don't delay—take it to a 4S shop immediately for inspection. They'll use professional tools to diagnose it and replace any necessary parts. During regular maintenance, pay extra attention to the braking system, testing it a few times to ensure everything is secure and prevent accidents.
