On February 18, 2008 at approximately 3:30 pm I was involved in an mva in which I struck the car in front of me at considerable speed. This caused considerable damage to my car (2007 Mercedes GL450) with no air bag deployment. During the attempt at stopping I felt the brake pedal become mushy and be ineffective. At first the brakes grabbed strong and then let loose with the eventual collision. After consulting with an independent Mercedes mechanic, it was suggested that this brake behavior could be explained by an anti-locking brake (ABS) sensor failure. This would account for the release of the brakes (possible detection of skid) but also the false data reaching the central computer with an erroneous speed, thus disabling the airbags. I have been in contact with Mercedes Benz or North America which has yielded no inspection or resolution. I have been asking for one of their field engineers to examine the car and see if the ABS sensor is responsible for the possible brake failure. Although the crash may still be my driver error, I don't feel comfortable repairing the car and giving it back to my wife for transportation of the family. Has an ABS sensor failure been reported for this model before?
