Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

My 2002 ML320 cluster display lights on my dash all light up, the check engine light comes on, the speedometer stops working actually goes to zero. Once the car comes to a complete stop it accelerates very slowly and will not shift out of first gear. This is very frightening for someone in traffic and this happens without warning. Please investigate this issue before someone is rear ended and dies.

To whom it may concern, I had a near death experience while driving one of your vehicles. I am the owner of a Mercedes 2002 ML320, which was purchased at a phillips Mercedes dealership in Virginia beach va. I need to address a very serious incident that occurred over the weekend (December 18, 2010). I was driving back from richmond going toward Virginia beach, I was driving 70 mph on I-64 and had it on cruise control, ahead I saw that traffic slowing down so I stepped on the break; I then realized that my brakes weren't working and I was unable to stop or slow the car down. I attempted to push the break pedal down and it wouldn┐T nudge even though I applied all of my weight to it, the speed did not diminish at all, I then tried the emergency brake and that also failed to slow me down, my friend suggested that I put the car in neutral and then try the brake, fortunately that worked and was finally able to come to a complete stop. It was one of the scariest experiences of my life. Your product put my friend's and my life in jeopardy. I had the bas/esp light come on in the pass and have brought it in for repairs 3 times already: 07/27/2005, 12/01/2009 and in 10/19/2010. I am stunned that a company who has such a great reputation and seems to thrive on customer satisfaction dropped the ball. At no point in time did any of the technicians who performed the repairs on my car advise me of the potential danger.

The contact owns a 2002 Mercedes Benz ML320. The contact stated while driving at approximate speeds of 60mph, the vehicle abnormally accelerated to speeds of 70 mph without driver intent. The contact attempted to apply the brakes but to no avail. She then applied abrupt pressure to the brake pedal using both feet and the vehicle began to slowly decrease in speed. She was able to stop the vehicle by engaging the emergency brake and shifting into neutral. The vehicle was towed to the dealer where she was awaiting diagnostic testing. The failure and current mileages were approximately 88,000.

[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!

Was driving vehicle on highway at 75 mph set speed in cruise control and stepped on brake as I approached traffic congestion. Vehicle would not stop and continued to maintain set speed regardless how hard I pressed on the brake. Eventually, I decided to try shifting into neutral and the vehicle was placed back under control of the footbrake. Thankfully, the vehicle was slowed down without incident but it was a very scary moment. Noticed, at this time, the bas/esp malfunction indicator lamp was displayed on the dashboard. Drove vehicle directly to a Mercedes dealership for repairs. Dealer advised stop lamp switch shorted. Replaced lamp switch. Although, this was the first incident while in cruise control the vehicle did have similar past problems with the braking system (ie-brake switch and shifter control module were replaced) that prevented shifting out of park into any other position. Vehicle should have safety device to override "cruise control" or prevent "cruise control" operation with any malfunction in the braking system or activation of the braking indicator lamp. What assurances are there to prevent this from happening again?
