What's wrong?
The headlights on the 2018 Mercedes-Benz C 300 4MATIC and C 300 are the front lamps that light the road and help other drivers see the vehicle. They are set at a specific height and aim point at the factory so the beam reaches far enough ahead without creating excess glare for oncoming traffic.
On these vehicles, the factory headlight adjustment system had worn during production. That wear left the headlights outside Mercedes-Benz production specifications. The filing says Mercedes-Benz ruled out blinding oncoming traffic, but the lamps still failed to meet the required lighting standard because the beam was not set correctly.
An owner can notice reduced headlight range, especially at night or on unlit roads. The road ahead looks shorter than expected, even when the lights are on. That is the warning sign to describe when calling a Mercedes-Benz dealer about this recall.

What should I do?
- Check your VIN to confirm your 2018 Mercedes-Benz C 300 4MATIC or C 300 is included in this recall.
- Contact a franchised Mercedes-Benz dealer to schedule the free headlight inspection and adjustment that corrects the low-beam aim.
- Bring the recall notice if Mercedes-Benz mailed one. If not, reference recall number 18V906 when you call.
- Drive cautiously after dark until the repair is complete, and avoid using the vehicle when reduced visibility makes the trip unsafe.
What happens at the repair
At the dealer, a Mercedes-Benz technician inspects the headlight setting and adjusts the headlights if they are outside specification. The inspection and adjustment are free under the recall. Mercedes-Benz is not offering a separate reimbursement program because the involved vehicles remain covered by the New Vehicle Limited Warranty. If you already paid for a related headlight adjustment, ask the service desk how that warranty coverage applies to your prior repair paperwork.
