Just thought I'd pass along some info on how I solved a rattle problem that developed last week. I was driving my wife's rx on Friday and noticed a rather annoying rattle on my left side, right by the window. It was a constant rattle and kinda surprised me, cause I never heard a rattle in the car before. I asked my wife and she told me she started noticing it last week. So I'm thinking what a pain, gotta take it to the dealer, yada yada...
I tried opening the window and noticed that when the window was just slightly bit opened the rattle dropped noticebly. When I got to our destination, I opened the window completely and pressed against the molding area with both hands all the way around where the top of the window glass usually resides. I felt just the tiniest clicking feeling as I pressed in the molding from front to back and back to front. Once we got back in the car, rattle gone. It's been a couple of days now and not a peep. Good luck on your rattle issues.

 

My wife's car has same rattle. Its been driving me nuts. I cant wait to get home and try this, thanks

 

My rattle was the plastic wind deflector under the driver's side door...transmitting the sound up through the A-Pillar. Dealer claimed they couldn't re-create it, found it when I inspected under the car. Used a grinder to cut the shaky part off...no problems since. I think there's a TSB out on it. I found the grinder method quick and easy, as opposed to stopping in at the dealer - again... G/L!

 

I dont know about dealerships some times.They can never seem to be able to duplicate the problems.But they still charge you for trying.

 

+ who has time to take the kids seats out, drive it there, pick up the loaner, exchange the car seats, go back and do it all over again? Come on man, you had the car for 5 hours and you couldn't figure it out on your own? -end rant-

 

my rattle came from the drivers side air vent just above the cup holder. the air deflector shakes slightly usualy at a stop.
