The problem is with the rubber seal at the back of the engine bay, which according to the statement below "may temporarily stick to the hood when it is opened and then may fall into the engine bay when the hood is closed." If it then comes into contact with the exhaust system, it could start a fire. And fires in the engine bay are never a good thing, unless they're contained entirely within the combustion chamber.
The issue affects an estimated total of 147,224 E-Class and CLS-Class vehicles, all told, across America – including four-doors, wagons, hybrids and AMG performance models (but no E-Class coupes or convertibles) from the 2013-15 model years. To fix the problem, Benz dealers will simply need to attach four additional clips to keep the seal in place, and will start doing so midway through next month.

The affected vehicles have a rubber seal at the back of the engine bay that may temporarily stick to the hood when it is opened and then may fall into the engine bay when the hood is closed.
If the rubber seal falls into the engine compartment, it may contact parts of the exhaust system, increasing the risk of a fire.
MBUSA will notify owners, and dealers will attach four additional retaining clips to the rubber seal, free of charge. The recall is expected to begin by mid-March 2015. Owners may contact MBUSA customer service at 1-201-573-5339. MBUSA's number for this recall is 2015020001.
