Recall 18V271000

Headlight Adjustment Screws Not Sealed To Prevent Adjustment

Recall Details

The sealing caps that prevent horizontal adjustment to the headlamps may not be effectively secure, allowing for mis-adjustment. Dealers will retrofit the sealing caps for the headlights free of charge to resolve the concern.

Our Quick Take

The headlights have screws that allow for horizontal adjustment, but these screws should be sealed off by sealing caps to prevent this. On affected vehicles, this may not be effective, allowing for misaiming of the headlights. This can increase risk of a crash.

What Should You Do?

Recall repairs on your Mercedes Benz vehicle must be performed by a Mercedes Benz dealership. Mercedes Benz will notify known owners of affected vehicles beginning in June, 2018. If you do not receive a notification, but wish to check to see if your vehicle is included, please contact one of your local Mercedes Benz dealerships. They will also check for any other incomplete recalls on your vehicle. For best results, be prepared to provide your Vehicle Identification Number (VIN) to the service department consultant you speak with.

Original Recall from the NHTSA

Manufacturer's Report Date
April 27, 2018
NHTSA Action Number
Potential Number of Units Affected
Mercedes-Benz USA, LLC. (MBUSA) is recalling certain 2017 Mercedes-Benz E300 4Matic, E300, E43 AMG, and E400 vehicles. The headlight horizontal adjustment screws on these vehicles may not be properly sealed behind a non-removable sealing cap to keep headlights from being readjusted. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."
If the headlight's horizontal aim is altered, a misaimed headlight may lead to an insufficiently illuminated roadway, which may increase the risk of a crash.
MBUSA will notify owners, and dealers will retrofit the sealing caps for the headlights, free of charge. The recall is expected to begin in June 2018. Owners may contact MBUSA customer service at 1-800-367-6372.
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to
