2002 MERCEDES-BENZ ML500 Complaints

There is a serious defect in the YAW rate sensors in these Mercedes ML W163's. Thank God I was driving down a secluded road and nobody was behind me, but my vehicles brakes locked up, on their own, even with my foot on the accelerator pedal, with no warning lights or warning signals. I have no error codes, and my vehicle is well maintained. There are many many people that are having the same issue with their Mercedes ML's. Some people have experienced this happening to them at freeway speeds. The YAW rate sensors are at fault, and send a signal to the ABS pump which in turn locks up the brakes without even touching the brake pedal! This is EXTREMELY DANGEROUS to everyone in the vehicle, and to ANY other vehicle in the area. People can DIE! Again.. This is a terrible defective function of a sensor that will spontaneously apply the brakes fully to lock up automatically with no persuasion from the driver. It is extremely dangerous and can cause fatal injuries. This has been researched thru many Mercedes forums including benzworld.org, mbworld.org, Mercedesforum.com, and ml w163 Facebook forum, all of which many ML owners have experienced the braking system lockup, and in some cases accidents have occurred. Another unfortunate issue in this happening, is that the brake lights do not light up when this sudden braking happens due to the YAW rate sensor malfunction. If there is a vehicle behind a Mercedes ML when this sudden braking occurs, there is NO WARNING LIGHTS, and can cause a serious accident and injury or death! Many people, including myself, do not feel safe behind the wheel of our Mercedes ML's for fear of the brakes locking up in their own because of this poorly programmed default function of a possible faulty YAW rate sensor. This is the worst default function to ever have a vehicle do. I now steer clear of other Mercedes ML's in the road knowing they can automatically lock their brakes for no apparent reason. Please research this and take action!

HOUSE FROM POWER STEERING POMP IS LEAKING , DURING DRIVE I LOOSE POWER STEERING FLUID AND ALMOST I HIT CAT FROM ANOTHER LINE.

THIS WAS THE 3RD TIME IT HAPPENED, THIS TIME ON THE FREEWAY IN CALIFORNIA AND LASTED UNTIL THE CAR CAME TO A STOP. THE CAR WENT INTO BREAK MODE ON ITS OWN, THE CAR FISHTAILED AND CAME TO A STOP BEFORE RECOVERING. LUCKILY THE CAR BEHIND ME WAS ABLE TO STOP, I HEARD BREAKS SCREECHING, BUT NO KNOWN CRASHES. I SCARED ME TO DEATH AS THIS COULD HAVE IT COULD HAVE CAUSE A MULTI-CAR CRASH. I PULLED OFF THE FWY AND INTO A NEARBY GAS STATION AND CALLED AAA TO TOW MY VEHICLE TO THE MERCEDES REPAIR CENTER. THEY CANNOT RE-CREATE THE PROBLEM AND I WILL NOT TAKE MY CAR BACK UNTIL I AM SURE THE PROBLEM HAS BEEN FIXED. MERCEDES NEEDS TO RE-OPEN THIS CASE AND FIND OUT WHAT IS HAPPENING.

I, 12 YEARS AGO WAS DRIVING MY ML 500 MERCEDES ON US 23 BETWEEN ANN ARBOR, MICHIGAN AND SYLVANIA, IN OHIO. MY CAR SUDDENLY LOST ALL POWER. I FORTUNATELY WAS ABLE TO SWERVE TO THE RIGHT AND THE CAR STOPPED. THIS OCCURRED TWICE. I HAVE SINCE SOLD MY CAR SEVERAL YEARS AGO. I CALLED MY DEALERSHIP IN SYLVANIA AT THE TIME, AND THEY CHECKED WITH MERCEDES, WHO RELAYED THAT IT HAS TO DO WITH THE WEIGHT OF THE KEYS ON MY KEYCHAIN. THIS SOUNDED EERILY SIMILAR TO WHAT APPARENTLY HAS OCCURRED WITH THE GM CARS BEING RECALLED. PLEASE MAKE SURE THIS ISSUE IS INVESTIGATED FURTHER SO THAT NO INJURIES THAT CAN BE PREVENTED HAPPEN .

WHILE DRIVING AT 70 MPH WITH CRUISE CONTROL ON ESP/BAS LIGHT CAME ON. CRUISE CONTROL FAILED TO DISENGAGE WHEN BRAKE PEDAL PUSHED TO SLOW VEHICLE, CAUSING ENGINE TO RACE FORCING VEHICLE TO SPEED UP ALMOST CRASHING INTO VEHICLE AHEAD.
