Problem: Mercedes-Benz USA, LLC.

For a full list of the affected models visit: https://static.nhtsa.gov/odi/rcl/2019/RMISC-19V787-4620.pdf
Risk: An inaccurate vehicle location may delay emergency responders, increasing the risk of injury.
Fix: MBUSA has initiated an Over the Air (OTA) remote update.

Risk: The leaking oil in the presence of an ignition source can increase the risk of a fire.
Fix: MBUSA will notify owners, and dealers will correct the oil level as necessary and replace the reservoir sealing cap to prevent oil foam from leaking out, free of charge.

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."
