The vacuum brake assist failed with less than slightly less than 50k miles on the car. Not sure exactly when it failed because the brake and traction control lights were on intermittently for awhile before we took the car in for service. We did have a near miss while making a long drive when we were trying to leave the interstate on an off ramp and I was almost unable to stop at the top of the ramp. I had to angle the vehicle to the left to avoid hitting a pickup truck at the top of the ramp.
