Steering: electric power assist system
NHTSA campaign 17V241000 · reported April 11, 2017 · Mercedes-Benz USA, LLC. · 58,323 vehicles potentially affected
The problem
Mercedes-Benz USA, LLC. (MBUSA) is recalling certain 2016 GLE300d 4Matic, E400 4Matic Coupe, GL63 AMG, GLE350, GLE350 4Matic, GLE350d 4Matic, GLE400 4Matic, GLE43 AMG Coupe 4Matic, GLE550e 4Matic, GLE63 AMG 4Matic, GLE63S AMG 4Matic and GLE63S AMG Coupe 4Matic vehicles, 2017 E300 4Matic and GLS63 AMG 4Matic vehicles, and 2016-2017 GL350 4Matic BlueTec, GL450 4Matic, and GL550 4Matic vehicles. The affected vehicles have an electric power steering connector that may be insufficiently sealed, allowing water to enter the control unit.
The risk
If water enters the power steering control unit, the power steering assist may be deactivated, increasing the risk of a crash.
The fix
MBUSA will notify owners, and dealers will replace the connector and inspect the electric power steering rack, replacing the rack as necessary. These repairs will be performed free of charge. Remedy parts are currently unavailable. Interim notices informing owners of the safety risk are expected to be mailed June 30, 2017. Owners will receive a second notice when remedy parts become available. Owners may contact MBUSA customer service at 1-800-367-6372.
