The HVAC blower motor may fail. This is commonly caused by water entry through the cabin air filter areas during heavy rain or snow. Failed blower motors should be replaced. Our technicians tell us there is no special fix for this issue at this time.

Due to a faulty seal around the tail light assembly, water may enter the rear compartment containing the spare tire. The water could damage the lift gate control module, causing it to fail.

This recall is expected to begin during April of 2009. The Mercedes recall number is 2009030003.
