I have a 2003 E320 Mercedes Benz with sbc brake system. The company has admitted having issues with the system and has extended the warranty to 25 years on the sbc pump. My car has on about 4 or 5 incidents gave me a red warning on my dash to stop the vehicle and see workshop. Each time this happens my braking ability is significantly reduced to the point of needing a lot of distance to stop. I have had the brake system flushed, that worked for a while. Around January of 2018 the dealer updated some kind of software package. January 2020 the brake issue happen again. I am being told that unless a certain default code is indicated they cannot replace the pump. I told Mercedes customer service that how will I know that the next time my braking is reduced will be my last time that will cause death or property damage to other drivers or my self before this default code comes up, a code no one will tell me what it is. I was told that they understood my concern but until this default code comes up they cannot replace the sbc. I find that statement to be not consider of life and property damage on our national highways

Brake failure occurred with no prior warning. Brakes are electronically controlled and complete loss of braking occurred while vehicle was in motion. Red "brake" and "ABS" lights in dash started flashing along with continuous beeping. Was able to bring vehicle to a stop within parking lot by using parking brake. Upon shutting off and restarting engine, vehicle regained braking. Car will not be driven until issue is addressed.

I purchased my current vehicle 18 months ago used. This weekend the giant stop light came on asking me to take the car into the dealership due to defective brakes. It turns out it's the sbc pump which was recalled by Mercedes Benz. Except, Benz will not repair it as it's a 2003 and out of their 10 year rule. It's a $2100 I cannot afford and cannot sell vehicle with this issue as I fear it may cause harm to others. A friend suggested I ask for NHTSA's help as Benz is unwilling to stand by the recall and repair the safety issue.

Brakes seeemed to working fine and out of no where at 65mph a red notification came on the dash saying "reduced braking effect/longer stopping distance visit workshop". Mercedes is aware of this because they extended the warranty on the sbc unit the is needed to safely operate the car but didn't do a recall and eventually stopped installing this part in the models. If the vehicle is 10 years old plan to shell out thousands since the part isn't covered and it is unsafe to drive because your brakes may go at any time. I have 96K on my vehicle and because it is over 10 years old the faulty part that the manufacturer knew about is not covered. The part is designed to malfunction at 300,000 compressions and this can happen at any time. This is unsafe and should be recalled! I hope someone doesn't have to die for Benz to do something about it!

Mercedes dealer says that my VIN number is not under this recall. I bought the car on July 31,2009 and the recall for the brake pump came out in October 2009. I have had the car serviced at the same Mercedes dealer for 8 years and they have never told me about any recall. Is my car covered under this recall. I understand there is a 10 years limit on the recall and Mercedes has been regularly servicing my car since year 6 to year 10 I.e. @009 to 2013 and they have never mentioned any recalls in any of the times I have had the car serviced since July 31, 2009.

I own a 2003 E320 Mercedes Benz with 67,000 miles. I took my car to a dealership and was told my sbc unit needs to be replaced. I was also told that the warranty on this component was extended but is now outside the extended warranty period. Why was not covered by a recall rather than just an extended warranty? this seems to indicate Mercedes is acknowledging a faulty component. This appears to potentially affect safety so I would hope Mercedes would be eager to replace the sbcs.

I been driving Mercedes for passed 20 years but never experienced scary moment like this. Thursday 09/01/16 on my way home from work out of nowhere red brake warning light lid up my whole dash with big stop sign in the middle, flashing with esp and ABS saying visit workshop and I lost 90% of braking power.luckily, it happened on open road with cars far ahead of me. Pulled aside and after few restarts warning went off and I made it safely home without towing service, keeping my left foot close to emergency brake pedal. Google search revealed to my surprise very common problem with Bosch sbc units installed in this model. Is this even possible for one of the top names in the world to limit their service cycle to 300,000 brake pedal applications" are some of the top engineers involved out of their mind? Mercedes, is it safe to drive this car in highway speeds with two kids in it? would one of the engineers like to take my car on the autobahn now to proof their point? I believe the counter is up with 13 years and 122K miles of service because all other brake components checked fine. Unbelievable??? where is the safety recall??? ended in 10 years??" what a shame for both Mercedes and Bosch names.

ABS brake system failure. While operating the vehicle a warning light blinks in the cluster panel. Then the vehicle loses all braking power. On Monday September 5th, I was driving on the highway, 110th South bound 1 mile South from downtown los angeles, suddenly a warning light appear with the following message 'brakes defective stop vehicle' the cars begins to downshift and it slows down. However the brake does not work in full. It appears that the brake works enough to come to stop after the vehicle has downshifted to the lowest gear. All braking ability is disable. After I research the code and narrow to the problem that I had, I noticed that merecedes Benz had extended the warranty for the ABS pump for these models for 10 years, since my vehicle is 2003 the warranty had expired on 2013. This is an electronic braking system so if an electric failure occurs there is no way to stop the vehicle. There is no manual brake power other than the emergency brake in order to stop this vehicle.

Recently on today 7-12-16 at 174,000 miles the display on my 2003 E320 4S Mercedes Benz all of a suddenly displayed an illuminated message in bright white : "brake" service brake visit workshop. My vehicle was in motion on a busy major highway when the hydraulic brake system exhibited this message. Shortly prior to this messaging, I notice my brakes were more hard to apply pressure, . I am glad I wasn't driving fast, this could have been a serious tragedy to myself as well as those others on the expressway just a as I was. 2. problem with my gas tank after I fill the tank, the gas fumes become so intense after parking this vehicle inside my garage. I didn't know there were a recall. Is this fuel safety hazard recall still in effect" if so, whom do I contact to have it repaired at no cost to me the owner? 3. 4 months prior in March 2016 I incurred a problem with the coolant fluid leaking into the transmission resulting in a major monetary expense out of my pockets above $5000. Can this be covered by the manufactuer so I may be able to be reimbursed"

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.
