you're not the only one having problems with your 04.
I got the ground effects package. My front lips weren't primed properly, all the paint started chipping off. After a lot of heated conversations with the manager, they finally decided to replace it for me.
My passanger door vibrates like crazy. There's even air leaking into the car.
My front 2 windows vibrate when i want to put them down. (i think its got to do with the motor).
Everytime I turn on the car and put it into Drive and accelerate, the engine makes 4 clicking sounds.
I love the engine they put into the new camrys, but the overall quality and finish is not the same as gen3/4s

. But thats just my opinion based on my experience.
