What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2010 Mercedes-Benz M166, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Reports naming the steering system — racks, columns, power-steering assist and steering linkage.
From owner reports, verbatim
AFTER DRIVING THE VEHICLE TO WORK (APPROX. 35 MILES) AND THEN RETURNING AFTER THE WORK DAY WAS COMPLETE, THE VEHICLE WOULD NOT START. WE SPOKE WITH THE MANUFACTURERS ROADSIDE ASSISTANCE AS WELL AS THE TECHNICIAN THEY DISPATCHED TO OUR LOCATION. WE TRIED MULTIPLE SOLUTIONS TO OUR PROBLEM WITH NO AVAIL. THE VEHICLE WAS TOWED TO THE DEALERSHIP AND UPON INVESTIGATION, THE ELECTRONIC STEERING LOCK MECHANISM HAD GONE BAD RESULTING IN A NEED TO REPLACE THIS PART. I HAVE DONE RESEARCH ONLINE AS WELL AS SPOKEN TO SEVERAL MEMBERS OF THE SERVICE DEPARTMENT AT THE DEALERSHIP WHO INFORMED ME THAT THIS WAS A GROWING ISSUE. THERE ARE MULTIPLE COMPLAINTS ONLINE OF SIMILAR ISSUES AND THE DEALERSHIP SAYS THEY ARE SERVICING 1-2 VEHICLES WITH THIS ISSUE EVERY DAY. WITH THAT TYPE OF VOLUME, THIS SEEMS TO BE AN ISSUE WITH THE SOURCING OR MANUFACTURING OF THIS PRODUCT. THIS IS A VERY COSTLY REPAIR THAT SEEMS AS IF IT COULD HAVE BEEN PREVENTED.
WHILE COMMUTING ON A HIGHLY CONGESTED HIGHWAY THE CAR LOST POWER CAUSING THE STEERING WHEEL TO BECOME LOCKED THIS LOST OF POWER AND DISABLING CAUSED MY CAR TO VEER INTO ONCOMING TRAFFIC AND TAKING MY VEHICLE UNCONTROLLABLY OFF THE ROAD
