Service Brakes Problems of Mercedes Benz SL550

Complete brake failure while driving. No one was injured but the vehicle could not be stopped until the transmission went into limp mode with still no brakes. Now the abs and srs lights on. Brake pedal to the floor. I completely have new brakes speed sensors fluid exchanges and more. The current recall doesn’t seem to cover my vehicle. I contacted the dealership and they said there are no open recalls.

The brake handle popped off for parking brake.

I bought the almost 3 years now since I bought it I seen and message on the dash board reduced braking power depress brake pedal fully . I search on the website most the mercedez benz has same problem but when check my VIN number I saw no issue on my Sl550 2009. I almost depress on my car ill spend a lot of money and its dangerous to used it I went to a dealer 2 years ago for but on their diagnose they don saw anything about this issue. Before its happen only when the weather is cold and car cold too but now while you on the road keep losing brake.

The vehicles brakes stopped working due to the sensotronic brake control unit. I'm told that there is a limited set number of how many iterations you can get out of this part before it stops working.

Frequently and intermittently (not every time) when I start my car's engine, the srs malfunction warning light and "take car to service facility" message display appear on the instrument panel. When the srs warning lights are illuminated, the windshield wipers do not work, irrespective of how the wiper controls are manipulated (one swipe . . . Intermittent swipe . . . Slow swipe . . . Fast swipe . . . Windshield washer squirter). When I try turning on the wipers while the srs malfunction warning light is illuminated, the roll bar malfunction alert yellow symbol illuminates on the instrument panel and I hear an audible clicking sound from somewhere behind the seats (this is a two-seater car). I tried cycling the roll bar all the way through its range of motion . . . From all the way stowed, to all the way deployed, back to all the way stowed . . . But this did not clear or change the roll bar malfunction alert yellow light, did not clear the srs malfunction warning, and did not activate the windshield wipers. Mb dealership replaced the "passenger seat occupancy switch gear," but this did not eliminate the srs warning problem. The second time I drove the car following mb's repairs, the srs malfunction warning light reappeared, the wipers refused to work, and the roll bar malfunction alert yellow symbol illuminated. I cannot drive the car in the rain if the srs malfunction light is illuminated, as it frequently is, nor can I depend on the srs safety system. I need to have these vital safety conditions resolved.

Almost exactly one year after dealership "fixed" the same problem, the brakes on the vehicle totally failed while driving. After the initial failure in 2013, I was assured that this problem was fixed. I was very reticent, but drove the care again. However, based on the second total failure of the braking system, the vehicle is worthless. Mercedes benz says they have fixed the problem, but it is the same assurance they gave me the first time. The car is 2007 sl 550 with approximately 60k miles.

The contact owns a 2003 Mercedes Benz sl500. The contact stated while driving approximately 40 mph, the brakes abnormally traveled to the floorboard when depressed. The contact referenced NHTSA campaign id number 05v133000 (service brakes, hydraulic) but was advised that the recall repair had been previously satisfied. The failure was recurring. The manufacturer was not notified of the problem. The approximate failure mileage was 24,679.
