“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!”

NHTSA complaint #11057753, filed 2017-12, 106,500 miles

“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. …”

NHTSA complaint #10923995, filed 2016-11, 135,000 miles

“While driving on the highway at 60mph the vehicle started shaking violently. The brakes started engaging on their own pulling the car to the left and right and nearly bringing the car to a sudden stop. It took a lot of effort to keep the vehicle from pulling into the other lanes and causing an accident. The bas/esp light came on the dash and has stayed on now. This all lasted for about 10 seconds. I was in the 3rd lane of a 4 lane highway during moderate traffic. I was almost rear ended by two different vehicles. …”

NHTSA complaint #10587996, filed 2014-05, 149,000 miles

“[mercedes benz ml 320 2002] while driving east on route 80 at 65 MPH and approaching the toll booths of the george washington bridge, I tapped my brakes to disengage my speed control. The speed control did not shut down. I hit the brake pedal several more times harder and harder, but the speed control stayed in control. I pushed down very hard on the brake pedal with both feet and although the car slowed a little, the speed control dramatically speeded up the engine with the tachometer going almost full scale. …”

NHTSA complaint #10330616, filed 2010-05, 118,206 miles

“The anti-lock braking system would engage without driver activation. The bas/esp light would come on without any reason either. One day I was on the freeway when it happened and suddenly the breaks were engaged at 73 MPH when I was on the fast lane and other vehicles following at about the same speed. My leg was on the accelerator gassing to continue, but the anti-lock braking system forced the car to almost a stop - about 10mph, before the breaks disengaged and the car continued to move (that is accelerate again). I almost got rammed by the vehicle behind me. …”
