TiresJan 17, 2025 · NHTSA campaign 25V023000 · 165 vehicles

Problem: Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2018 E 400 Cabriolet, E 400 Coupe, 2019 E 450 Cabriolet, and E 450 Coupe vehicles.

As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 139, "New Pneumatic Radial Tires for Light Vehicles."

Risk: Tires inflated to an incorrect maximum pressure may have insufficient strength, allowing the tires to fail and increasing the risk of a crash.

Fix: Dealers will inspect and replace the tires as necessary, free of charge. Owner notification letters were mailed March 7, 2025. Owners may contact MBUSA customer service at 1-800-367-6372. MBUSA's number for this recall is 2025010008.

Fix: MBUSA will notify owners, and dealers will inspect the communication module and activate it, if necessary, free of charge. The recall began March 31, 2021. Letters for the owners of the 9 additional vehicles were mailed July 9, 2021. Owners may contact MBUSA customer service at 1-800-367-6372. MBUSA's number for this recall is 2021030005.
