Why Your Mercedes EQE350 Keeps Turning Off Its Daytime Running Lights

If you own a 2025 Mercedes-Benz EQE350, you might have noticed something odd: the daytime running lights sometimes shut off on their own, even after you’ve turned them on. One frustrated owner recently shared the problem on a forum, describing how a warning message pops up at startup saying the lights are inactive.

They then have to dig through the MBUX infotainment system to manually reactivate them. S.?

S. regulations require all new cars to have daytime running lights that activate automatically when the engine is running. But in this case, the EQE350’s system seems to have a mind of its own. The owner notes that the lights occasionally “switch themselves off” even after being enabled, which suggests either a software glitch or a setting that’s not saving properly.

It’s not a widespread recall issue, but it’s happening enough that other owners might want to check their own vehicles.

If you’re experiencing this, you’re not alone. The first step is to make sure your MBUX settings are saved correctly, sometimes a quick system reset can help. But if the problem persists, it may be worth a trip to your dealer for a software update. At Boca Auto Care, we’ve seen similar quirks in other Mercedes models, and we recommend keeping your vehicle’s firmware current.

For now, the best advice is to double-check your lights before driving, especially if you rely on them for visibility. Have you noticed this behavior in your car? Drop us a line, we’d love to hear your story.
