Defect

Mercedes-Benz USA, LLC. (MBUSA) is recalling certain 2020 CLA250, CLA250 4MATIC and CLA35 AMG 4MATIC, 2020-2021 GLE350, GLE350 4MATIC, GLE450 4MATIC, GLS450 4MATIC and GLS580 4MATIC and 2021 GLE53 AMG Coupe, GLE63S AMG 4MATIC, GLS63 AMG 4MATIC and Maybach GLS600 4MATIC vehicles. The instrument cluster software may deactivate the illumination of certain interior switches (switch bar, overhead control unit, steering wheel) if the hazard lights are turned on and the ignition switch is in the 'off' position. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 101, "Control and Displays."

Consequence

If the interior switches are not illuminated, they may be more difficult to find and operate, increasing the risk of a crash.

Remedy

MBUSA will notify owners, and dealers will update the instrument cluster software, free of charge. The recall began March 31, 2020. Owners may contact MBUSA customer service at 1-800-367-6372. MBUSA's number for this recall is 2020030019.
