Mercedes-Benz is recalling 2016-2017 Metris vans in 22 states and the District of Columbia, where road salt could corrode and fracture aluminum bolts. That could lead to the loss of power steering and a crash.
The company said corrosion occurs when water mixed with road salt penetrates the housing that covers aluminum bolts for the steering gear and power pack.
That could cause the power pack to separate from the steering gear. If that happens, the customer would hear a noise. A warning light would turn on to warn of the loss of power steering. That loss of driving assist would require more steering effort at lower speeds.
All the recalled vehicles could have the issue. No crashes from the condition are known, the company said.
The regional recall affects 9,471 vehicles in what the National Highway Traffic Safety Administration calls “salt-belt states.”
The states are Connecticut, Delaware, Illinois, Indiana, Iowa, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, Virginia, West Virginia and Wisconsin.
Mercedes-Benz dealers will replace the aluminum bolts with steel bolts for free. The company substituted steel bolts for aluminum and added wax to the steering gear in an August 2016 production change.
The NHTSA recall number is 19V-290.
