What should I do if my Mercedes blind spot assist sensor is not working?

Yesterday, I was driving in a big thunderstorm and my blind spot monitor stopped working. Bad weather is when I need that feature the most! How can I fix a broken Mercedes blind spot assist sensor?

Liz Jenson · Updated on Mar 20, 2023

Reviewed by Shannon Martin, Licensed Insurance Agent.

I’m sorry to hear that you’re dealing with this issue! I hate to say it, but it’s actually somewhat common for the

blind spot assist sensor to not work in inclement weather. For best results, try to avoid large puddles and other sources of water when driving.

The good news is the system will typically reset on its own when you turn off the vehicle. But if it continues to malfunction—even in dry weather—you should visit your dealership to have the issue checked out.

While you’re learning how to keep your blind spot sensors clear, why not learn how to save on your car insurance, too? It’s easy— just use the

app.
