took my 07 crewmax in to get the pedal done and mentioned to the guy, for the second time, about the rear end drop problem and the feeling like i'm being rear ended sometimes when i'm at stoplights. he said Toyota knows about it and if they get enough complaints that maybe they'll issue a recall or TSB. i know a lot of you guys have this issue too, but i have no idea who to complain to. seems like telling the local dealership wouldn't help much. any ideas?
