Description of the defect

Mercedes-Benz USA, LLC. (MBUSA) is recalling certain 2019 C300, C300 Coupe, CLS450, E450 Coupe and S450, 2017-2019 E300, 2018 E400 Coupe, E400 Stationwagon, and 2018-2019 S560 vehicles that have previously had the instrument cluster replaced. The software in the replaced instrument cluster may cause the seat belt warning system to not operate properly, only displaying a solid warning light if either the driver or passenger seat belt is unfastened, instead of a blinking light with an audible tone.

Potentially affected

56

What can happen

Without the audible tone and blinking warning light to remind the front seat occupants that their seat belts are not buckled, they may forget to buckle their seat belt, increasing their risk of injury in the event of a crash.

Remedy

MBUSA will notify owners, and dealers will update the instrument cluster software, free of charge. The recall began September 8, 2020. Owners may contact MBUSA customer service at 1-800-367-6372. MBUSA's number for this recall is 2020080015.
