Thanks! The dealer had cleaned the battery post but not the cable. It appears that was the problem (car started first try after cleaning). I will know for certain in the next couple of days.

It was working perfect when we took it in. Dealer is saying it's just a coincidence.

I took my 2007 400H in for a oil change and the Toyota dealer said my battery needed to be replaced as it was really low on cold cranking amps. After they installed the battery it would take at least two tries to start the car. A call to the Lexus dealer suggested a new battery in the key fob and then two days later it would not start at all. Connecting the battery to a charger showed that it was low and needed a charge. My old battery was working fine when I took the car in. Does anyone have an idea what could have happened?
