“There is an active recall for the all activity module on 2001 m class vehicles. There is an extensive amount of data that owners from the release of the mercedes benz ML430 have had problems identical to those in the active recall. When I call mercedes, they say my car is not impacted. Based on the number of issues and history on 2001 m class all activity modules, I feel this recall should extend to all 2001 m class cars.”
NHTSA complaint #10549512, filed 2013-10, 117,000 miles“The all activity module (aam) does not function properly to which neither side mirrors can be adjusted because the windows no go up and down or longer operate. Then the door locks no longer functions and various other components rely solely off of this middle instrument cluster. When I took it to the dealer they said there is a malfunction in the aam controls which are the causing affect of this issue.”
NHTSA complaint #10934046, filed 2016-12, 150,000 miles“Was driving 50 miles per hour when the car slammed on the brakes, nearly getting me rear ended. The throttle would not respond until the car was doing maybe5 miles per hour - on an interstate! The BAS/ESP light was on solid. I got onto an off ramp, called the dealer, was told it could be several causes, drove home carefully, and took it to the dealer. The dealer found nothing. Several times since, the car was being driven at speeds in the 20-30 miles per hour range, and the system would slam on the brakes and pull hard to the left. I could smell the brake dust in the car. …”
