2 Electrical System problem

Failure Date: 02/01/2018

My 2008 is having the same problem as this 2009. Mercedes benz is recalling 16,130 my 2009 m-class w164 passenger vehicles equipped with the optional power lift gate. As a result of a faulty seal around the rear tail lamp assembly, water may enter the rear compartment containing the spare tire. Water contamination of the control unit for the power lift gate can result in disabling of the power lift gate motor. Hazard:water will cause a short circuit which could lead to a fire. Remedy:dealers will replace the seal of the rear tail lamp assembly with a thicker one and reposition the affected power lift gate control unit inside the chassis. This service will be performed free of charge. The recall is expected to begin during April 2009. Owners may contact mercedes-benz at 1-800-367-6372. Additional info:Mercedes Benz recall no. 2009030003. Owners may also contact the national highway traffic safety administration's.
