My car have none of your issues too bro.
For your info, I sold off my 2011 Camry because of sound orchestra in my cabin.
The reason was partly due to my mistakes too....installation of aftermarket dvd player and tint with an accessories shop.
These accessories shop use Myanmar workers and their fittings were absolutely rubbish. Need to dismantle my centre of dashboard uncountable times to settle the creaking noise.
5 months down the road...I can hear all the loose noises coming up again and worse still....my driver side door power window become loose....Toyota say warranty cannot cover since I put aftermarket tint.
So I learnt my expensive lesson not to open up anything in my K5...I have not even tint my car.
Perfectly alright so far.

Yeah bro, I argued with Toyota, but they said cannot cover. I tried 3 different SC and all gave the same answer.
I paid to replace it, and then removed all the additional tint before selling off the car.

My tint was 3M bro...not a cheap one.
How to say that its not a reputable shop?
