Just an update. I had the Brake system malfunction warning appear on the way home Sept 18. I drove straight to the dealer and left the key on as instructed. Received a loaner (ford focus) and was called on Monday and informed they have a call into Ford engineers. Later in the week I was informed that they are waiting on a improved connector for the brake booster assembly. Repairs were compleated and my Fusion returned to me on October 2. Only had 1 day of driving but all seems well will find out in the next couple of days if the fix is permanent. The repair notes read that they (Ford Engineers) wanted the brake booster and connector sent back un disturbed. This required the wires into the connector to be clipped and the entire booster replaced and a new connector installed. It seems they have had a couple of other occurences of this as well. Other than the long wait for a repair I still like the Fusion, back to 40+ MPG :)

I haven't had the check engine light since they cleared it in saturday but I hace had several occurences of brake system malfunction and just last night one event of the little yellow qrench. According to the manual it is "throttle control/ powertrain malfunction. Seems to be temp/time related and only occurs after about 15 miles of mixed continious driving.

Well it gets better, I had the check brake system light come on with the same symptoms just befor reaching my destination in the morning and also this after noon. This evening I had the brake system warning and the "throttle control/ powertrain malfunction" indicator as well. In all cases a key cycle restores normal operation. My local dealer said to bring it in when the faults are active. Hopefully tomorrow they will come on during my ride home past the dealer.

Brake system warning light associated with loss of the power brake boost system-brakes still worked just harder to operate. This has happened twice on my 2010 fusion hybrid in the past 2 weeks. Currently have 2500miles, I too have also experienced the check engine light related to the egr fault as well. Back to the brake system, when driving in stop and go traffic I heard a warning chime and saw the check brake system warning indicator. When I applied the brakes it was apparent that the power boost assist has shut off. Pulling off to the side of the road and cycling the key switch turned the warning off and restored normal brake operation. I just hope this does not occur when the brakes are really needed. The dealer reset the codes, the check engine light went off by itself after 3 driving cycles as the manual indicated for a temporary fault. The dealer said the engineers are working on a solution. The brake system checks ok but they reported the event to ford engineering. The down side to having a car with modern tech. is that the dealers seem to be playing catch up with technician skill sets. In particular the hybrid vehicles. Other than that the fuel economy is great.
