Enroute from palo alto to mountain view and was at a complete stop waiting at a stop light on a major thoroughfare (central expressway) when the car stopped running. Cars behind me proceeded to pass me to make the left turn while my car was shut down. I was able to re-start the car after ~5 - 10 minutes and drive another 1000 feet when the car stopped running again. Prior to both incidents the panel indicated an alert "transmission fail" and a "check engine" alert. The car would not start back up and had to be pushed through the intersection to a street where it could be parked safely. Initial autobody electronic diagnosis and repairs related to battery replacement, however, transmission related fault codes still showed up. Fortes brothers autobody discovered "safety" related notifications issued by BMW and therefore recommended taking car to BMW. Car was then towed to BMW mountain view dealership where service department diagnosed and then replaced both hydraulic pump and clutch. Based on subsequent research on the internet, there are references to hydraulic pump recalls by BMW for BMW M5 2005 model. Although my car is a BMW M5 2006 I am requesting follow up to confirm that the hydraulic pump is manufactured to all required specifications and does not pose a safety risk.
