NHTSA Complaint #11620728 — 2015 MERCEDES-BENZ E400

The sub frame of this car is being replaced under a warranty extension due to severe rusting and separation creating an extremely unsafe driving condition. It was determined during inspection the rear brake lines were also corroded. This is also due to environmental exposure and substandard materials of construction. Many E classes of the W212 and prior have this concern but Mercedes is not covering the brake lines as part of this warranty. In fact they are charging up to $4000 to replace with the subframe already removed!! This is highly concerning as this is a safety concern that must be covered.
