Mercedes Benz ML320 abs comes on

Filed Apr 30, 2022 · Brakes, Driver assistance · CA

The car brakes suddenly by itself just after the ESB/ABS lights come on along with an exclamation point (!). This has happened randomly at least 4 times since we purchased the car. Once at high speeds on the highway. It appears this problem is common with other owners of Mercedes 2001-2002 ML's. According to the forums below, the problem seems to be a "YAW RATE SENSOR" malfunction or defect. My Mercedes mechanic saw no error codes for this component and it seem extremely expensive (forum states part is $3000) to replace.

While driving at 50 MPH, vehicle lights started flashing (warning for esp and ABS) and the vehicle slowed dramatically and pulled to the right... I got to the side of the road and assumed I had a blow out... But all tires were fine and no issues... Turned off vehicle and drove about 13 miles then turned vehicle off for 10 -15 minutes came out and got in vehicle... When I started to go... Orange triangle was still on and if I even touched brakes they all locked up and would even squeal when even touching brake petal. It was 79 degrees, dry on a highway that was a smooth road, in traffic and was almost hit. Updated 05/11/16

Was driving truck at highway, when brakes activated by itself, ABS, traction light, brake lamp and hazards flashed. Had to immediately move to side of road, while brakes where activating. Felt as if ABS was activating as if I was sliding on and icy road. Had to have vehicle towed as I was not able to move more that 5 feet

Same story as I've seen thousands of times on the internet and you claim not enough occurrences! I'm on the interstate, going 70 MPH. Weather is good, traffic is light (thank god!) and my breaks slam on. The ABS system kicks in, so I'm able to get over to the shoulder before being rear ended. The triangle warning lamp is lit and the bas / esp lamp is lit. I try turning the car off and back on, lights go out, I move forward, get up to about 20 MPH and the breaks slam on again. I shut the car off for about 15 minutes while I got out and was investigating the tires and breaks. Get back in, start the vehicle and drive another 45 minutes. Get into town, driving about 25 MPH and they slam on again. I'm able to limp home with the ABS going on and off. I park it for the night. Next day I do some research and see there are thousands of similar complaints. Follow one of the suggestions and disconnect my battery. Fixed the issue for about 4 months before it happened again. This time I was in the passing lane going around an 18 wheeler with traffic behind me. Me and my 8 year old was almost killed along with other drivers. This is a life threatening issue that you can't ignore. It has happened 4 or 5 times in the two years I've owned the vehicle.

I have experienced multiple incidents of a situation where the ABS, esp, and ets lights come on and a noise occurs when depressing the gas pedal at low speeds. The noise stops only when the brake pedal is depressed or at speeds over 40 MPH. There is also a vibration that occurs that can be felt by depressing the brake pedal. The noise continues as soon as the brake pedal is released. The car becomes difficult to drive. Turning the car off and on again does not clear the problem. When the car is turned off, a noise can be heard coming from under the hood that sounds like a motor or a fan that is running. This continues for hours. The hood of the car becomes warm to hot to the touch. At some point the fan or motor stops running. If the car battery has not been drained, the car functions normally--until the next time that the problem occurs. After a quick internet search, I found many similar reports of these symptoms by other owners of this make and model vehicle of the same or similar year of manufacture. The vehicle owners have received diagnoses of a bad ABS control module, a bad ABS pump, bad solder joints on the ABS pump assembly's circuit board, or bad relays in the fuse box. Repairs have cost in the thousands of dollars for what is apparently, a known defect. Drivers of these vehicles have been subjected to frightening incidents where their safety has been compromised by their vehicles. I realize that the law governs safety defects in cars manufactured within the last 10 years. However, people with older cars need recourse for known defects. A mercedes such as mine, that only has only a little over 100k miles and that has been well maintained, has a life expectancy of at least another 50k to 100k miles. However, they should be safe miles.
