Sbc brake unit which control the brakes just failed when driving on highway,very limited braking,very scary when you are driving 70mph. I have read that this is major issue with Mercedes Benz ,some kind of penalty should be assessed to them because this is a dangerous situation. It just cost me 2380. 73 to get my car fixed and I understand this is a problem that will keep happening over and over again. Hopefully it's a situation that the ntsb can look into about this defected unit from Mercedes Benz. Thank you.

The sbc brake unit failed while I was on vacation. The rest of the brake system works fine.

It is an electronic braking system.

6 Brakes Failed problem

Failure Date: 09/11/2015

I was driving on route 5, branch Ave. , near clinton, MD, about 30 mph, down slight decline of a hill, approaching a place in the road where cars can enter the highway from both the left and the right. As we normally do, I pressed on the breaks to slow down, in case one of the cars sitting on both the left and right, decided to enter on to branch Ave. My brakes failed - the foot peddle went completely to the floor when I was trying to slow down, there was little to no control in the steering wheel and I looked at the dashboard and it was lit up in red warning lights , first saying brake need maintenance (or something) at first. I manage to get the car to steer towards the right to get on the side of the road, hoping the rough terrain would help to slow the car to a stop. By this time the red warning lighted up dash board said stop, brake failure or something. The car finally stopped and I turned if off. I am 59 year old woman and was absolutely petrified - my whole body was shaking from the fear that I was going to wreck on this busy highway. Luckily for me the cars waiting to enter the road, did not and cars on the highway slowed down and went around me while the car was coasting towards the side of the road. There was no warning light telling me to get the brakes services - they just failed while I was driving on the freeway. I called mercedes roadside service for them to pick up the car. After an hour and they had not arrived, I turned the car on, there was no red light. I pressed the brake and it didn't go to the floor but it was soft and went nearly to the floor. I kept pumping the breaks - something I used to see my father do - thinking that would bring the breaks back up so that I could at least drive back home to await service truck. I let mercedes service know, then I slowly drove back, side roads, pulling over to allow cars to pass until got home.

7 Brakes Failed problem

Failure Date: 09/08/2015

I was traveling on a secondary road at a speed of 30mph when the mfd turned red, started beeping and stated brake failure, stop driving. When I attempted to stop, the brake pedal went to the floor and the transmission automatically down shifted. After pulling the car to the side of the road, I put the transmission in park where it locked in place. After fifteen minutes the sbc reset itself and the transmission unlocked. The vehicle was removed to the mercedes dealer where I purchased it. The mercedes tech stated that the sbc needs to be replaced. I was told there was a 10 year warranty on the sbc unit, but it expired in June 2013. I am the original owner and Mercedes Benz USA stated that they did not notify the owners of the warranty extension or of the problems with the sbc. The cost to replace the sbc is $2,000.

I was driving down a side road by a college in lowell MA and my dash board lite up and starting beeping. Said brake failure sort stopping distance, visit work shop ASAP. I tried to stop the car but it was very hard stopping it, I honked the horn because I was coming up on a school crossing( thank god) they all moved out of the way because I would have ran over them all. I got the car stopped and shut it off, police over saw the whole thing and pulled up behind me and I explained what happened, we went to go start the car up and all the light where off and the car seemed fine, there was no way I was taking that chance again so I called a tow truck and had it towed to my garage, mechanic just called me and said nothing was stored in the computer system and the brakes are working fine now. He checked on line to see if there where any other complaint about this issue and informed there a lot of problem from Mercedes Benz owners on this issue. I will not drive this car again, I could have killed all those people in the walk way because of this problem that mercedes is aware of. Please help ! I just looked up the same information on google and there are hundred of complaint about the same issue, my brakes are new. It is a electrical problem that they are aware of.

9 Brakes Failed problem

Failure Date: 01/03/2015

My wife and I were traveling northbound on texas hwy 281 just north on marble falls texas. I noticed a train coming and started to slow down and made the decision to stop for the train! well at that time my brake dash warning came on and it was all red and my brakes failed. Their I was not able to stop going 75 miles per hour (legally) and I could not stop and it was way to late for the train to stop also so I floored it to get over the tracks then I finally came to a safe stop. I searched the internet for a fix and to my surprise mercedes had known of this for many years and stopped all help with the issue when the car reached 10 years old. This car should be fixed by the company that knowingly put it on the road with an experimental new type of braking system then tells owners down the road to kiss their butt. And its now the owners problem. What a deal my car is in great shape but has a defective experimental braking system that mercedes will not even discuss fixing. I should hav bought a corvair or maybe a pinto at least you can stop them! wow why have you not jumped all over this manufacture about this deadly problem even you have known for years! but no one has told me??? the title should be marked deadly in bold letters.

12 Brakes Failed problem

Failure Date: 11/08/2013

I was driving to work when my brake system failed. My car displayed a code stating "brake defective; stop vehicle". This occurred on a busy highway in rush hour traffic. I am a pregnant female and was in the car alone, it was terrifying. After having my car towed to the dealership, I learned of an extended 10 year warranty on the sbc unit of my car. Since I bought this car used, I was not the "registered user" even though I have the loan and title in my name. The warranty expired in sept of 2013. After my car was diagnosed, it was found that it was the defective sbc unit that failed me. I had previous similar codes (none that caused my brakes to fail) related to this sbc unit defect in April 2011 & August 2013 to which I purchased new brakes. It is not know whether this was necessary or not since my code of "service brake" at those times are a part of the faulty sbc unit and not necessarily related to the safety of my brakes. After my case was reviewed and denied at the corporate level, my husband and I had to shell out $1135 to fix the part ourselves. My husband was previously laid off and just started a new job in June. I feel it is unfair that we had to pay this money when we take good care of the car and were not privy to the information to fix the brake system within the warranty time. I worry about other people who have this car, are unaware of the warranty, and are outside the warranty. I was lucky to not have damage or injury. I feel mercedes should be held accountable. I also feel I should be reimbursed as this was not a wear and tear issue and I feel it was handled unfairly on the corporate level of mercedes. Thank you for your time.

13 Brakes Failed problem

Failure Date: 06/04/2013

On June 6, 2013, while braking on approaching intersection, brakes failed and transmission locked. Mercedes customer assistance towed vehicle to dealer, m-b greenway, houston, TX, where the service advisor explained that the pressure reservoir of the sensotronic brake unit had failed and must be replaced at a cost of $1,350. I complained that the sbc unit was the subject of NHTSA safety recall 05v0133 and two mbusa recall campaigns (2005070007 and 2005110001) resulting in the extension of the original warranty to 10 years with no mileage limitation. The dealer refused to honor the warranty or replace the entire sbc unit, because the electonic diagnostic code required by mb USA, llc for a dealer to file a warrntry claim under the NHTSA 05v033 campaign did not appear on the diagnostic equipment. I paid the disputed $1,350 charge and drove the car about 6 miles on June 6, 2013, wnd the brakes again failed and the transmission locked. Mercedes customer assistance towed it back to m-b greenweay, where the service stated the entire sbc unit had failed and must be replaced at a cost of $2,030. I complained that the replacement was mandated at no cost by NHTSA 05v0133, but she said mb USA llc would allow the dealer to honor the sbc warranty because the car was "driven out of the shop. " she also refused to credit the $1,350 charge I paid for the sbc pressure reservoir replacement, but offered to "discount" the replacement of the entire sbc unit to "$1,799. ".

Complete brake failure. Almost crashed. I have numerous fault codes in computer, abs code, sbc code, resivior code, etc, etc on a 58,000 milr car! they are telling me only one part has extended warranty and that is the sbc. Everything else I must pay for. The sbc effects all of these other parts and that is crap! like which came first? the chicken or the egg. Why have you not effected a complete recall of this make & model as everyone is having the same problem. You and mercedes are going to get someone killed as the brakes go to manual and it's hard panic stoppng a 3400lb car!!!!!.

2003 E320 mercedes brake failure!! -------------------------------------------------------------------------------- I bought this car in 07 with 65,000 miles a good deal. Fine car! however. . . Today while driving to work a red brake failure warning. . . Flashes across the screen and my car would not stop!!! I am rolling across a small country rd bridge and thankfully am at the bottom of a steep hill. The brake pedal just flopped. . Nothing. . I managed to get it into park and get out with the car still running!!! I've had it towed two hours away. . . While waiting on my husband to get home to go the dealership with me, I located about 3 recalls on this model. . Question. . . What responsibility does this used import car dealer have to me as a customer? they are consulting the mercedes dealership to see if it is indeed an issue with a brake/hydraulics recall. . I don't want to drive this car again. . I owe some money on it. What could I insist they do???.

16 Brakes Failed problem

Car e-320 Mercedes Benz 2003 with 53404 miles while my wife was driving this car, the vehicle panel indicated a total brake failure and she had no breaking response from the car at all. She was traveling at around 40 mph but says she had no one in front of her so she let the car coast to a stop, she had no breaking power at all. At this time she called me and I had her take photos of the car panel lights and then I contacted Mercedes Benz. We know that there has been a recall for this issue on these vehicles, based on information that I found filed with NHTSA. The biggest problem is that the exact same incident happened to her on this same vehicle back in January of 2009. At the time of that incident she was at a parking lot and driving very slowly. We contacted Mercedes Benz and were told to bring the car in. Mb said that the car required an sbc control unit upgrade (software) and the job was done at no cost to us. So here we are, 16 months and about 9,000 miles later with the same issue again, both times this problem could have resulted in a serious accident and we are happy that this was not the case. Although mb has already made an appointment for us and I was told that the problem will be resolved at mb's cost, this time they indicated to me they will be replacing some part (?) and not just doing an electronic update. Of course my wife is now very scared to drive this car, even if they do the repairs and I do not blame her. We will see. In doing internet research I found many other complains that are very similar, where there is a total electronic failure of the break system (no stopping power at all, no dual-system back-up). In other complaints if the car is turned off and then re-started the problem goes away. This is exactly what happened to my wife's car. This problem is serious enough that should be properly addressed and research so as to avoid accidents.

17 Brakes Failed problem

Failure Date: 04/07/2008

While I was driving the car in 35 miles speed, all of a sudden the brake system failed. I was unable to control my 2003 mercedes e 320 and I was almost dead crossing a heavy traffic area. Fortunately I turned the car left to a parking lot and changed the gear to parking to stop the car and to avoid getting in to the shop. I bought the mercedes with a trust, but I lost my trust. Not only that I am still waiting to get the repairing cost from mercedes due to the product defect.
