Daimler AG will be asking owners of some 2015 Mercedes-Benz C300 and C400 sedans to return their vehicles to a Mercedes approved repair facility to have the steering system inspected for a manufacturing error that could result in loss of steering control. According to reports filed with the NHTSA, an improper assembly procedure could result in the steering coupling interlock mechanism not being locked in place. The sliding shaft could become disengaged from the coupling as the result of vibrations, steering thrust, or load feedback from the road surface. If the shaft becomes disengaged the driver may experience noises, steering backlash, and/or loss of steering control.

Owners wanting more information about the defect are asked to contact Mercedes-Benz USA customer service at 1-800-367-6372. MBUSA’s recall number is 2014090008 and the NHTSA campaign number is 14V-598.
