my 500 does the same thing. Try to make a right on a red light. Its pretty much 50/50 if the car will rev/downshift/accelerate as you would expect it to. I might die someday from side impact, just trying to make a right turn. You pretty much take your life into your own hands anytime you try a semi aggressive (read: normal pre-2006) driving maneuver.
what we have here, everyone, is the advent of the electronic throttle and assholes who work in the engineering departments of the carmakers who program the throttle / tranny combos in insane and dumbass ways....i.e. 'protect the consumer from themsleves'. Its probably all tied to the legal department and lawyers somehow.
My 500 actually downshifted and took off today when i turned a corner at a stop. I just about crapped my pants. I didn't realize my car could do that. Pretty zippy! Now the damn thing won't do that again anytime soon.
Most cars as we know them downshift to 1 when you come to a full stop. Mine don't. It waits until you take off again, so the car stumbles and then the only way to get it to downshift is to literally floor it. Then the car jerks into gear and feels like its gonna break apart.
I assume this all due to electronic throttles and trying to program the trannies to either last longer, get better mpg, or save iditos from putting the car into the ditch.
I'd like to put my car into a ditch. the ditch outside my ford dealer.
I have a TSB available for a tranny reflash on my 500. I'll do that soon and see if the same problem is fixed. I totally bet the Camry is having the exact same issues.
