| Today my husband was involved in a car accident while driving my 2007 gl450. thank god he wasn't injured but the situation he explained to me has happened several times before and i've been able to regain control of the car before something terrible happened. he left home for work at about 6am and while still in the subdivision driving about 20 miles/hr on a road with about 1 of snow, he tried to make a right turn but the brakes locked and the steering wouldn't turn and he ended up smashing the front end on a huge stone and ricocheting to a fire hydrant. like i said, this has happened before and i'd been assuming that the skidding was because our tires were worn but we got brand new tires less than a week ago so this does not make any sense. i haven't been in touch with mercedes yet but i will be contacting them to advise them of this issue. *tr | |||

| Tl*the contact owns a 2007 mercedes benz gl450. the contact heard a squeaking noise when he depressed the brake pedal and the stopping distance increased. the dealer was unable to diagnose the cause of failure, however, they grinded the edges of the brake pads to reduce the squeaking noise. the speed was unknown. the failure mileage was 4,000 and current mileage was 6,600. the dealer recommended chamfering the brake pads to alleviate the noise. the dealer stated vehicle low on oil. updated 09/2807 *tr | |||

| 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? *tr | |||
