Mercedes-Benz USA (MBUSA) is recalling 42 model year 2017 E300 4Matics, E300s, E43 AMGs and E400s.
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.
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.
What to do
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.
