Whether the radar host line is loose, the buzzer is broken, or the wiring at the bumper is damaged. Here is some related information about Mercedes-Benz: 1. Meaning of the name: "Mercedes" means happiness, implying that the cars produced by Daimler will bring happiness to their owners. Mercedes-Benz, a German automotive brand, is considered one of the most successful premium car brands in the world, renowned for its perfect technical level, high-quality standards, innovative capabilities, and a series of classic coupe models. 2. Noble products: Currently, it mainly produces C-Class cars (mid-range sedans and coupes), E-Class cars (high-end sedans and coupes), S-Class cars (luxury sedans and coupes), and G-Class vehicles (SUV off-road vehicles).
When I was driving my Mercedes-Benz GLA, the radar stopped making sounds. It's possible that the sensors were covered by dust or mud, causing signal interruption. Clean the surface immediately to prevent dirt from blocking them completely. A blown fuse is also a common cause—check and replace the corresponding one in the fuse box. If there's a short circuit or damaged wiring, use a multimeter to test it. A faulty control module can affect the entire system and requires professional diagnosis at a 4S shop. Software bugs may also need firmware updates to fix. Driving with a malfunctioning radar increases the risk of backing into walls, so it's best to troubleshoot simple issues first or visit a repair shop if needed. Regular maintenance can reduce such problems—don’t let them escalate.
The radar on my Mercedes GRA occasionally doesn't beep, probably because I accidentally turned off the setting. Go to the central control screen to confirm the alarm function is on, and make sure it's not in silent mode. The sensor may also malfunction if covered by rain or snow. Usually, wiping the surface with a cloth after parking helps. Low battery voltage can affect device operation, so check the charging status. Operational errors are common among beginners; develop the habit of testing the radar function before driving. If resetting the system doesn't work, there might be an internal component issue, and it should be handed over to a technician. Safe driving is the most important—don't overlook it.
My Mercedes-Benz GLA's radar suddenly stopped working after several years of use, most likely due to aging sensors, loose connectors, or worn components causing poor contact. Long-term vibration and high temperatures accelerate part fatigue, while insufficient battery power can also lead to unstable power supply affecting operation. Regular maintenance such as cleaning sensors and checking wiring can prevent minor issues from escalating. Ignoring repairs leads to higher costs, and replacing with new parts is often the solution.
