PhotoMercedes-Benz USA (MBUSA) is recalling 5,754 model year 2018 AMG S63 4MATICs, AMG S63 4MATIC sedans, AMG S63 4MATIC Cabriolets, S450 4MATIC sedans, S560 4MATIC coupes, S560 4MATIC sedans and Maybach S560 4MATICs.

Due to an incorrect steering boot installation, the Active Steering Assist system may remain engaged despite the driver's hands not being on the steering wheel for a prolonged period of time.

If the system remains active despite the driver not having his hands on the wheel, the driver's inattention may increase the risk of crash.

What to do

MBUSA has notified owners, and dealers will inspect the vehicles and correct the steering boot installation, as necessary, free of charge.

An interim letter was mailed to owners on February 14, 2019 to notify them of the issue. A second notification will be sent when the remedy is available.

Owners may contact Mercedes Benz customer service at 1-800-367-6372.
