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.

I have a 2003 Mercedes SL500 with 52000 miles on it and suddenly the brake warning light came up and the investigation linked it to the sbc hydraulic recall (2005070007). Mercedes had extended the warranty on sbs unit for 10 years and my car is now out of that extended warranty period. The sbc issue did not occur until the car had over 51000 miles. I reached out to Mercedes Benz customer care and they wanted me to take the car to the authorized dealer which I did and the dealer's report clearly states that they could not connect to the sbc pump and it needs to be replaced immediately. Mercedes Benz customer care called me back stating that the car is out of the 10 year warranty period and does not qualify for the replacement. As a matter of fact, I was told that there was no recall on the entire sbc pump and also stated that it was only on the installation of bracket, which happens to be another recall on the sbc unit (2005110001). The vehicle does not adequately stop due to this failure and the repair cost to replace the sbc unit as stated by the dealer is $1939.75. This is clearly a safety recall that is a concern and so would like to request nhsta to advise.

While driving at approx. 20-35mph I pressed the brake and almost went to the floor with no resistance. Dashboard indicates red warning "stop" brake defective, stop vehicle with yellow ABS warning light. After I pulled over, parked the car and shutting down the engine... warning lights, red emergency "brake" illuminated. As well as, reduced brake effect, start engine and followed by incr braking distance, start engine.

While driving to work, I was going about 35 mph when the dash lights up red saying "service brakes, stop vehicle, etc". my mechanic looked over everything to do with brakes and could not fix it. He called Mercedes of tallahassee and was told it was an electrical issue that was a common problem with this vehicle. It did have a recall on it, but it expired in July last year, just my luck. So I googled it and have now found tons of people with the same experience! how can the vehicle safety administration legally allow Mercedes Benz to continue letting this happen to people" how many accidents must take place, or god forbid deaths before something is done" I have no option but to pay out of pocket to have this piece of $100K junk fixed and pray it never happens again! Mercedes Benz and the vehicle safety administration better pray this doesn't cause an accident or I will sue the [xxx] out of both! information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

My wife was driving about 1/2 mile from our house when the brakes completely failed. She was on a back road and had to brake for a stop sign. She was able to pull off on the side of the road, to avoid rear ending a car stopped at the stop sign, and finally bring the car to a stop. The brakes started to work with about 1" of pedal from the floor. She said it was so hard to push on the pedal that she could barely do it. Luckily she was not hurt. Had this happened on a major road or highway the results could have been catastrophic. Apparently this was the first year for a new braking system referred to a "drive by wire". euro motorcars in md informed me that because Mercedes had so much trouble with this new system that they extended the warranty for this problem for 10 additional years. The new extended warranty on this brake failure issue was for complete parts and labor. I was never notified of this extended warranty. No one at the dealership, where I have had the car serviced exclusively, notified me of any warranty extension for this very serious braking failure issue. I find this reprehensible! my wife could have killed. Why was such a serious braking issue not made a recall instead of "if you have a problem warranty extension"? at the very least Mercedes should have recalled all cars with this potential braking failure. The problem lies with the sbc hydraulic braking unit. The car was towed to euro motorcars where it was repaired. I asked the service writer if it could be covered under the extended warranty and he told me that the extended warranty had expired this past February 2013. Mercedes told me the same thing. Tough luck! in addition to helping recover this expense of $1593.81 please explain to me why this was allowed to happen. No recall and no notification. Someone could have killed!
