| Description of the problem | When attempting to exit the highway, the sensotronic brake control system (sbc) failed and there were no noticeable brakes. The pedal went all the way to the floor with no resistance. Manufacturer claims that if you apply additional pressure during a failure, there will be some braking power available. In the situation though, when the pedal goes to the floor, human instinct is to immediately find an alternative way to stop the car. I was able to stop by downshifting the transmission and applying the emergency brake. Less experienced drivers may not be so lucky. Mercedes benz usa is aware of the potential for all sbc electric pumps to fail at any time causing this same situation for anyone. They are unwilling to cover the defective part because i am one year beyond the 'extended warranty.' they claim that as with any car parts, the sbc system can be expected to fail at some point. Anything beyond 10 years and they do not take responsibility for. Normally i would agree with that sentiment, but not when it concerns the primary electric system of electric brakes to fail. There should at least be a sufficient and noticeable hydraulic back up if this part is engineered to fail. Mercedes has recently extended all fuel tank related issues and components to 15 year coverage, and this would at least be a step in the right direction for the sbc system. However, i believe mercedes benz usa and the nhtsa should mandate a recall of all vehicles equipped with sbc to be inspected yearly and replaced free of charge for the life of the vehicle. I believe it is just a matter of time before there are significant deaths or injuries due to this problem - as the affected vehicles are all about 10 years old at this point. It is a valid concern for both me as a driver of an affected vehicle, and a concern for fellow motorists and pedestrians on the road. |
