NHTSA's recall notice
As NHTSA's recall record states it for campaign 15V657000.
Defect description
Mercedes-Benz USA, LLC. (MBUSA) is recalling certain model year 2015 S550 4Matic Coupe, AMG S63 4Matic Coupe, and AMG S65 vehicles manufactured January 27, 2014, to April 2, 2015. In the affected vehicles, left-side front seat belts may have been installed on the right-side and vice versa. As a result, the installation angle may be incorrect, affecting the seat belt locking behavior. Additionally, the child seat restraint function for the passenger seat would not be available. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 208, "Occupant Crash Protection," and FMVSS number 209, "Seat Belt Assemblies."
Safety consequence
If the seat belt is installed improperly, it may not properly restrain the seat occupant in the event of a crash, increasing the risk of injury.
Manufacturer remedy
MBUSA will notify owners, and dealers will inspect the installation of the seat belts, correcting them as necessary, free of charge. The recall began on October 30, 2015. MBUSA's recall number is 2015100002. Owners may contact MBUSA customer service at 1-800-367-6372.
Notes
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 www.safercar.gov.
