After rainy day in N.VA I found water in the tail lights, right in the reflector part of the light in both sides only. The car was parked all day near house on rain.
Anyone had same problem?
It's very bad because I have removed rear decorative panel and found water on electrical connectors, because soon as I have open rear gate up the water is started escaping from the hole on upper frame of the rear gate. So it can developing corrosion plus can short a computer.

I don't want bash Lexus/Toyota, but I was expecting a better quality for this car. My other car 03' BMW 325i doesn't have water leaks. Well may be I will not buy Lexus or any Japanese car ever again. I had Acura 3.2TL too and it had enough problems that turn me out from Honda brand.

 

From your vantage point it is a problem that you did not expect and are experiencing it. Just because you experienced/ing it, you can not conclude that it is prevalent problem. I am sure there are lemons in all brands and lines, wherever the vehicle is made.

If you are within warranty, take it to the dealer. There is some seal that is broken or a drain plug that is clogged.

If you are out of warranty, use the other side as a reference and find out what went wrong.

Have it looked at as things can go worse from bad. Your reflectors may become permanently tarnished and fuses may start popping.
