I am having safety issues with my 2001 Mercedes Benz ml 320 with a esp bas light coming on and locking front brake causing the abs to come on and stop SUV. To avoid an accident and almost getting rear ended with my kids in car. Contacted mercedes dealer and cant guarantee what problem is already changed brake light switch 2 times said it could be abs pump {800} or wheel speed sensors {1200} or yaw sensor, ignition switch, maybe even computer but said they could not guarantee to fix this problem. Mercedes benz should have a recall on this issue it has been going on for years some one is going to get killed. Spoke to benz at corporate and they only say bring it to the dealer who does not know how to fix this problem. Hope I can get a answer to this situation.

Then on Dec 28, 2012 I was driving back from sacramento, CA to my home in san leandro, CA. I was on the 580 freeway in livermore going around 75 miles in the fast lane and the car suddenly braked on its own. This time it was a sudden and severe braking action. It caused the tires and brakes to smoke. My two children were in the car with me. What I noticed this time was the upside down exclamation light on the dash came on right as the car was braking. The bas/esp light came on. I drove about 40 mph to get my family home. I didn't drive the car for the rest of the weekend. My advisor at mb of pleasanton. He told me it was the brake light switch. The car has been doing this on and off since Nov 2012. It will go several months without this "self-braking" action then it will do it on and off for weeks. I am so scared to drive it and even more afraid when I have my kids in the car. Recently (April 2014) I was almost rear ended by a big rig on the freeway as a result of the sudden braking. I took it to smythe european in san jose. They said it was the yaw sensor and that needed to be fixed. My this time I have replaced brakes and tires as a result of the wear from the braking. I was told I would need back tires too. The yaw sensor was replaced. I got my car back on a Friday (April 25th) and it drove fine. On Monday(April 28th) I was going to lunch and the car braked on its own. Fortunately I was only going about 5 mph bc I was at the light. I called my mechanic and was told that if its still braking it must be the aam and that's an additional $1000 repair. Mercedes benz is aware of this problem but since no one has died yet, it is not being handled properly. I need help and resolution before the fatality is me, my family or someone else's family.

[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. I was able to reduce the car's speed from about 65 to under 50 mph, but was still pretty scared. This was a terrifying experience and as an engineer I realized my options and time to react were very limited! I figured my choices were few: 1) brake until the car either stopped or I had hit the stopped cars at the toll booths (maybe damage the transmission further), 2) shift the car into neutral hoping that either the speed control would disengage or at least I could stop the car (engine rpms might run away and destroy the engine), or 3) try to shut off the speed control with the control stalk on the left of the steering column (which I obviously could not read closely to figure out where the stop might be). Fortunately, with several tries I was able to find the stop position on the speed control stalk and disengage the control. I braked very hard to stop short of a collision. . . . . And got harsh words and looks from the adjacent toll collectors. I suspected that the brake light switch was not working and this was confirmed by my mechanic (eddie rodriguez of eddy's total auto care). The mechanic also has to replace the brake pressure sensor. My wife is insisting that I get rid of the car immediately and buy a new car. I love my ml 320. . . . . But I love my wife too!.

The contact owns a 2000 Mercedes Benz Ml320. The contact was driving with the cruise control activated and when she tapped on the brakes to disengage the component, the vehicle accelerated abnormally as opposed to decelerating. The contact had to shift into neutral in order to stop the vehicle from accelerating any further. The vehicle was towed to the dealer who diagnosed that the brake light switch was defective and needed to be replaced. The failure recurred five times and each time, the vehicle was taken to the dealer where the identical, diagnosis was provided. The vehicle was not repaired. The manufacturer was made aware of the failure who did not offer any assistance, stating that the vehicle was no longer under factory warranty. The failure mileage was 100,000 and current mileage was not available.
