There are 2 parts that are not covered that will get a stiff pedal, the
first will be the Dual Function Pressure switch and the other would be the
Accumulator, if the Accumulator goes out it will cause the pump to cycle
everytime the pedal is pressed. the switch will cause the pump to not turn
on

Update: problem has become intermittent...

Went to another dealership, they found a low accumulator fault code, but
couldn't get it to fault again after two days. Of course, once they
returned it to me, it faulted on the drive home...returned to dealership,
(same fault code) but they couldn't pin it down or get it to fault again
after a few days of trying...

Since then it's faulted once more...but fixed by turning on/off the
ignition switch until the ABS pump starts up. Also seems that the
problem occurs in stop&go heavy traffic where I'm riding the pedal a lot.
Other times there's no problem...

Sort of at a loss on what to do here...

Did you look up a five star dealer.
Did the dealer offer to fix it for you?
That thing is under a life time warranty as stated in upper post.
Get right on there case and or call the 800 customer service no in your
owners manual.

I've been to *two* "five-star dealers" so far...

The first one said "ABS computer problem" & quoted some high $$$ options,
which I didn't take up, so replaced computer myself...

The second (which I used to deal with regularly), can't get the brakes to
fault while in the shop. When I specifically asked about the
warranty/recall, their answer was that the problem could be "one of five
or six things", and that they would be on the hook if they replaced the
recall items and Chrysler found that they weren't faulty. I can
understand their stance to a degree, but from my point of view it
bites...

I'm running out of local 'five-star dealers' to take this thing to...

Thats not good to have an intermittent Low accumulator fault because you are
loosen pressure and could possible loose all brake pressure

Once again, A low accumulator fault is a pressure problem.More then likely
the pump is not kicking on.

Of course it happens in stop and go driving because each time you hit the
brake pedal the pressure drops and the pump is supposed to kick back on when
the pressure drops to 1600 psi. The pump will kick on and turn off once the
pressure reaches 2000 psi. The pump is not turning on when it is supposed
to.If you get the lite to stay on and the pedal goes hard take a long
extension or pipe and tap on top of the ABS pump motor ( located just under
the throttle body on top of the transmission) and with the key on see if the
pump turns on. If it does, the pump is bad and will need replacing, (part or
the Bendix10 recall)

Not all true MT... A stopped up return filter, a worn out accumulator, a
faulty ABS relay or the Dual function pressure switch is not covered under
this recall and will cause the same problems as the OP is talking about. But
agreed that he should take it back to the dealer be it five star or not and
tell them it is NOT fixed and he wants it fixed NOW!!

I thought I told you that this module has nothing to do with your problem
long ago before you replaced it??

Call that 800 customer service no in the owners manual and tell them
what the dealers are pulling on you.
And then tell them you want it fixed on there dime.
It is under a lifetime recall so get on there case.

Yep, but still replaced it since 1) it was faulty anyways and the 1st
dealership had this "do not pass go" attitude where they didn't want to
investigate further until it was replaced...

BTW, I talked to an independent repair shop today & they told me that the
ABS computer needs to be "programmed"...funny enough, it's not mentioned
anywhere in the Chilton manual. So forgive me if I take any information
with a grain of salt these days...

Today, it faulted after about half an hour of driving, stopped/restarted
a few times to see if the pump would turn on...it wouldn't. Tapping the
pump had no effect. Got back home (carefully!) and waited 3 hours, and
started the van up again...bingo...the pump turns on for almost a minute
and the fault lights go out...Temperature/overheating problem???
