The vehicle brakes have stopped working on this vehicle three times. The Integrated brake system has been worked on several times with loss of brake power happening while I have infants int he car with me several times. The BMW dealership, BMW Fort Washington in Pennsylvania, ahs failed to repair it several times despite requests. I lost braking power today and almost hit two different vehicles which I barely avoided by taking dangerous evasive action. Numerous warning lights came on inside the vehicle: 1) ‘Drive carefully. Brake System’ 2) ‘Parking Brake’ 3) ‘Reduced Driver Assistance’ 4) ‘Recall or Technical Campaign’ This is the third time this has happened. I was in less than two weeks ago and the B<W dealership assured me the vehicle was safe to drive despite the warning lights being on and the recall light being active. They told me nothing to worry about and this happened this morning. This is unacceptable.
