The '09 FEH has a much better brake pedal feel than my '05 FEH. It's like comparing non power brakes to the '09 FEH. The '09 FEH has been out almost a year before the '10 FFH and no programming problems that I've heard of yet. There may have been a brake programming change because of the variable voltage converter (VVC) in the FFH.

In trying to mask the regenerative braking, they had to change the pedal feel with software, which means the software could have a bug. This is the same problem that the Gen 3 Prius has encountered. The programmed "feel" can cause the user to think that there is no braking being applied.

I have not heard that it affects the 2009-2010 FEH, but it is the same sort of programming.
