Recall 10V366 covers 3,552 2002-2010 Mercedes-Benz G500, G55, and G550 vehicles for reduced front turn-signal visibility. Repair is free at any franchised Mercedes-Benz dealer.
Mercedes-Benz is recalling 3,552 2002-2010 G500, G55, and G550 vehicles because the grille cover used to protect the front turn signals can interfere with FMVSS 108 visibility over time. Reduced signal visibility makes the vehicle harder for other drivers to read and increases crash risk; the dealer repair will be free once available.

What's wrong?
The front turn signals on the 2002-2010 Mercedes-Benz G55, G550, and G500 tell other drivers when the driver is turning or changing lanes. These lamps have to stay bright and visible enough to meet federal lighting rules, including FMVSS 108. On these G-Class vehicles, a grille cover sits in front of the turn signal to protect it from damage.
In NHTSA campaign 10V366, Mercedes-Benz says that protective cover is allowed, but over time it can interfere with the signal's ability to meet the minimum visibility requirements. The problem is not the driver using the signal incorrectly. The concern is that the cover changes what other road users see from the front of the vehicle.
There is no warning sign before failure. An owner is not expected to feel a change from the driver's seat, so the issue is handled through inspection and recall repair, not by waiting for a dashboard light or driving symptom.
Who's affected?

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific SUV is included.
What's the safety risk?
Reduced turn-signal visibility makes it harder for other motorists to see when the vehicle is turning or changing lanes, which increases the risk of a crash. Until the improved turn light units are installed, use extra caution when signaling and changing lanes. Repair will be free at any franchised Mercedes-Benz dealer once available.
What should I do?
- Check your VIN to confirm your 2002-2010 Mercedes-Benz G55, G550, or G500 is included in this recall.
- Contact a franchised Mercedes-Benz dealer and ask whether the free turn-signal-unit repair is open for recall number 10V366.
- Bring the recall notice if Mercedes-Benz mailed one, or give the dealer recall number 10V366 when you call.
- Use extra care around traffic until the repair is complete because reduced turn-signal visibility raises crash risk.
What happens at the repair
The recall filing says dealers will install improved front turn light units designed for vehicles equipped with grill covers. Once the dealer repair is available, a Mercedes-Benz technician replaces the affected turn signal units with the improved parts so the lamps meet the required visibility performance with the grill protection in place. The repair is free under the recall, including parts and labor. Ask the Mercedes-Benz service desk to confirm the campaign is open for your VIN before arranging the visit.
