Why is the Buick Excelle's reversing radar not beeping?

Buick Excelle's reversing radar not beeping is most likely an issue with the buzzer. Here are the specific details:1. Introduction: The full name of the reversing radar is "reverse anti-collision radar", also known as "parking assist device". It is a safety auxiliary device for parking or reversing, consisting of ultrasonic sensors (commonly known as probes), a controller, and a display (or buzzer).2. Function: When reversing, it helps the driver "see" things that are not visible in the rearview mirror, informing the driver of the surrounding obstacles through sound or more intuitive display. It relieves the driver from the trouble of looking around when parking, reversing, and starting the vehicle, and helps the driver eliminate blind spots and blurred vision defects, improving driving safety.
I've been driving a Buick Excelle for a while and have encountered the issue of the reversing radar not beeping several times. Generally speaking, dirty radar sensors are the most common cause - for example, mud or debris on the bumper blocking them prevents distance detection and causes silence. You can try cleaning the sensors first with a damp cloth; those small circular dots on the rear bumper. Additionally, the radar system might have been accidentally turned off - check the vehicle's menu settings to see if the reversing assist option is enabled. Sometimes loose wiring connections can also cause problems, especially after driving on bumpy roads for extended periods. If these simple fixes don't work, it could be a blown fuse or faulty control module. I recommend going to a 4S shop promptly for professional diagnosis, as malfunctioning radar during reversing can be quite dangerous - better not take it lightly.
As someone who loves tinkering with cars, I know the Buick Excelle's parking radar system is quite reliable, but if it's not beeping, there are usually a few things to check. First is the cleanliness of the radar sensors; dirt or snow buildup can affect their detection capability, leading to no audible alerts. Second is a system setting issue—some cars allow the radar to be turned off via steering wheel buttons or the central control screen, so try resetting it in the vehicle settings menu. Third involves electrical issues, such as a blown fuse in the fuse box or a broken circuit due to poor wiring contact. Fourth could be a malfunction in the radar module itself, though this is less common. If you're handy, you can do a quick check, but for safety reasons, it's best not to DIY for too long—once you spot an issue, take it to a repair shop.
