Very seldom can you get away with just one battery replaced. Good idea to check the whole charging system.

What I want to know is if the OP ever got back the $350 the delaership charged him for replacing the "bad" switch that turned out to not be the problem.

well, mine is doing it again as well. If it sits for a day without running it'll give me the check brake system message when cranking. Of course my dealership only replaced one the last time so........you see where that got us. This will be battery #4 since february 2010.

check the sensor at the master cylinder or the brake pedal.

Maybe your fluid is low or you actually need to check your brakes?

I'm glad this thread resurfaced recently. It would have been hard to find that is was related to batteries with a title of "check brake system."

Last few days my 08 with 56k miles has been having trouble starting. It won't turn over at all for a couple of seconds and then all of the sudden it will crank and the "check brake system" message will show. This is different than what I typically expect with a battery going bad. Usually, they will turn over slow which is a good sign of an impending death of a battery. Also, all the gauges will max out for a couple of seconds. Regardless, I'm going to assume it's the batteries. I bought the truck 3 years ago with 36k miles, so I have no knowledge of the batteries. The passenger battery is Motorcraft and the driver side battery is Autocraft.

I did just complete a 1300 mile round trip to Ft Wilderness at Disney World. I had the refrigerator in the travel trailer running (propane) but I assume it needs a little current for controller board. It also sat overnight once keeping the refrigerator running. I wonder if this contributed to the battery issue.

If I have to jump start truck, does it matter which battery I connect too?

Thank You
