What Causes Automatic Parking System Failure?
3 Answers
Automatic parking system failure can be caused by the following reasons: Lever cannot be fixed: The parking brake lever cannot be fixed; the lever needs to be replaced or reinstalled. Brake failure: The parking brake fails; it is necessary to inspect and replace parts such as brake pads. If the parking brake makes abnormal noises or is aged, lubricant should be added or the brake should be replaced. Excessive gap: If the friction pads of the automatic parking system have too large a gap with the brake drum, or if there is oil contamination, severe wear, exposed rivets, or surface hardening causing slippage, the brake pads and brake disc should be replaced.
I've driven many cars with auto-hold function, and there are quite a few common failure causes. If the sensors are covered by mud or dust, they can't detect obstacles; the vehicle's electronic modules might malfunction, such as internal wiring aging or short circuits; sometimes the software system isn't updated or has conflicts, leading to misjudgments; insufficient battery power can directly affect power supply stability. There are also human factors, like frequent starts causing overload. I recommend starting by cleaning the sensors and checking the battery status. If that doesn't work, take it to a professional shop to diagnose the ECU with a scanner. Regular system maintenance can avoid many troubles—after all, safe driving comes first. Mishandling these small issues can lead to big risks, especially when reversing, as it's easy to get scratches.
The auto-hold function on my car stopped working last week, and I almost hit the wall while reversing—it scared me to death. Possible reasons include dirty sensors failing to detect objects, sudden software freezes, system hibernation when the battery is weak, or common issues like loose wiring or blown fuses. A friend’s car even had problems due to aftermarket audio modifications interfering with the system. A simple DIY check is to wipe the sensor area with a damp cloth and restart the vehicle. If that doesn’t work, don’t force it—get a mechanic to look at it immediately. Once this feature fails, parking becomes a hassle, especially in crowded areas where accidents are more likely. Make it a habit to check regularly to avoid such scares.
