Check if your Mercedes-Benz has a Recall

 


This is to notify you of the Recall Campaign LAUNCH for certain  MY13-16 E-Class, E-Class Coupe, S-Class, and SL-Class (207, 212, 222, 231 platform) vehicles. Please review the recall information below. The recall campaign is visible on the www.safercar.gov website and may generate questions from customers.  All affected VIN will be flagged as โ€œOPENโ€ in VMI on October 6, 2017.

 

Issue

Daimler AG (โ€˜DAGโ€™), the manufacturer of Mercedes-BenzeBay logo vehicles, has determined that on certain E-Class Coupe (207 platform), E-Class (212 platform), S-Class (222 platform) and SL (231 platform) vehicles, electric power steering control units might have been equipped with improperly soldered contacts. If the pins lose complete contact, the vehicleโ€™s electric power steering may deactivate, increasing the risk of a crash. In addition, the complete loss of electrical connection could lead to a short circuit within the control unit, increasing the risk of a fire.

 

What Weโ€™re Doing

MBUSA will conduct a voluntary recall campaign to electric power steering rack on the affected vehicles. Work instructions are available in StarTek Info
