Brakes: “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.”

I was enroute to the mercedes dealer ship to purchase a switch for my electric windows. I had noticed enroute that the vehicle seemed to not be shifting. I looked down to see if I had someway manually shifted down. I had not and when I attempted to accelerate it seemed I was in second gear.
