Brake pedal is hard when starting the vehicle. Brake pedal turns soft when engine is started. The brake pedal is so hard that it requires significant force to depress sufficiently to start the engine. This indicates loss of vacuum in brake booster when engine is off. The vehicle is equipped with a start/stop system and it seems likely that the brakes would not sufficiently hold the vehicle when the start/stop system turns off the engine.

Me and my son were traveling on a business road trip from my home in Lincoln, CA to do business at several companies and end up at a customer located in Anaheim, CA. We started on [XXX] in Roseville, CA highway Interstate [XXX] traveling towards Anaheim with stops along the way. We were coming down [XXX] on the southside of the grapevine at the speed limit of 70 MPH, when the engine began to stall, and the steering also began to lock up. We began losing control of the vehicle and engine power was failing and stalling. In addition, the stall was impacting the car battery. We had difficulty steering the car and controlling the direction of the car and getting the car to the side of the road. Once we were at the side of the road, we looked up the closest Audi dealership, fortunately we were 3.9 miles away from Audi Dealership in Van Nuys, CA. Once on the side of the road the vehicle initially would not restart the engine stalling had drained the battery. We waited on the side of the road for approx.. 40 minutes and were able to restart the car and drive with much difficulty to the Keys Audi Van Nuys dealership. We were able to barely get into the dealership parking lot when the car completely stalled, we went in and met with the service manager. We explained what had happened, and with the service teams help we pushed the vehicle into a bay to get reviewed. I have purchased eight (8) Audi-??s over the past years for me and my wife. The service manager promised to review the problem. Typically, Audi service will give you a vehicle to drive but the had no vehicles available, so they told us they would take us to a rental car company and cover the cost of the vehicle except for the insurance on rental car, which we had to pickup at a rate of $ $35 per day. As we were on a work trip we had to hustle to our customers as we had a meeting scheduled for 2:30 PM at Manna Beverage in Anaheim, CA. We went to our meeting and then returned to the Audi Dealership in Van Nuys. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF I
