Recalls
3 vehicle recalls from the manufacturer. Repairs are free. Check your VIN to see if one is still open on your car.
Child seat Vehicle recall #14V158000 · 2014 · 69 vehicles
What's wrong: In the affected vehicles, the foldable second row seat bottom May not fold down low enough to allow proper use of the child seat achors. As such, these vehicles do not conform to Federal Motor Vehicle Safety Standard (fmvss) number 225, "child restraint anchorage systems."
Why it matters: Without the use of the lower anchor points, a child restraint May be insufficiently or improperly anchored to the seat, increasing the risk of injury to the child in the event of a crash.
The fix: Mercedes will notify owners, and dealers will inspect and, if necessary, replace the seat pan of the second row seat, free of charge. The recall began on May 2, 2014.

What's wrong: Mercedes-benz USA, LLC.
