“The brakes totally failed with little warning. In mid-october, 2018 driving about 15 MPH my brake light came on and then within approximately 5 seconds alarms started sounding and I totally lost all braking power. Mercedes of denver repaired. On december 17 same exact thing happened at an even slower speed but this time the loss of brakes was instantaneous. Very concerned what would have happened had this happened at higher speed.”

Fast swipe ... Windshield washer squirter). …”
NHTSA complaint #10692093, filed 2015-03, 34,700 miles“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.”
