It seems that this vehicle was not included in a brake booster recall which included this model from 2005 through 2015.

Somehow, this vehicle was not included in the recall, but definitely should have been.

This was part of the recall and the dealer installed a drain and replaced the board. HOWEVER, this issue again happened nearly one year later in our next rainy season. After taking it to the dealer, they said WE would need to …

Their diagnosis confirmed water intrusion into the blind spot radar sensors, consistent with Mercedes-Benz TSB LI54.71-P-056477. Both left and right sensors and wiring require …
