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.

I was driving on a busy intersection in my 2002 mercedes benz ml320 when driving the yellow triangle in the speedometer starts to flash and all the breaks lock up, this is followed by a stall, thankfully I was able to pull off to the side of the road without being hit. After doing some research I discovered that many mercedes ml320 owners were having this same problem. Specifically the yaw rate sensor. This is a serious life threatening issue that can injure or worse yet kill someone. You guys need to do a recall before someone dies!

On numerous occasions occurring in different conditions regarding speed, weather, road conditions, etc., I have had the vehicle pull hard to the right while engaging the front brakes, both while turning the vehicle and on straightaways. When this occurs, the triangle hazard light and esp lights start flashing. Most often I have been able to pull off to the side of the road, thankfully safely, or on one occasion stop in the middle of the road as the car wouldn't allow me to continue driving which was incredibly dangerous and scary. I have taken it to the dealership who replaced the front brake sensors, which didn't fix the problem, and returned to have them again diagnose the issue and declined their recommendations such as replacing the back brake sensors, until I came upon the repeated issues of the stability sensors failing (specifically the yaw sensor). I can't believe that, to date, this has not been a recall issue and no one has been seriously injured or killed due to this problem (I filed a previous claim, but the website went under maintenance and closed my complaint as I was filing and was given id #10923983, but there is no information filed in association that I could find hence the re-filing).

On multiple occasions and numerous different speeds, weather, both driving on a straightaway or turning, and other road conditions, the front brakes have locked up on the car causing it to veer right while engaging the brakes. Most often I have had to pull over, thankfully safely, or on one occasion, stop in the middle of the road to turn the car off to be able to continue driving which is incredibly dangerous and scary. I've taken it to the dealership and they had me replace the brake sensors which were obviously not the problem and then recommended other replacements, since the problem continued, that I declined until I found that this was a common problem with the stability sensors in this vehicle (specifically the yaw sensor). I'm amazed this is not a recall situation and that no one has been seriously injured or killed due to this problem.

Brakes applied on their own without pedal pressure while car was moving at highway speed. Front brakes were smoking by the time I found a safe place to stop off the 4-lane road on a side road. Rear brakes seemed hot, but not smoking. No warning lights came on. Immediately before this highway event, car had just been traveling around 35 MPH on hilly side roads with steep ascents and descents. This is the fourth time brakes have self-applied in a similar manner. After second event, dealer examined car but could not reproduce the problem or find any faults on computer diagnostics. When brakes cool, car restarts without brakes coming on. Brake pads and sensors were replaced 6,000 miles earlier; significant brake drag was present for around two hundred miles after that repair; dealer said brakes were self-adjusting and declined to examine car at that time. It was about 4,000 miles after brake pad/sensor replacement that the self-braking problem started.
