I thought about just buying the driver one and keep it in the attic until that one breaks as a precaution.

If your window makes loud noises when openning and closing, you should take it in. That is the precursor to it fully coming off track.

I wanted to know if this is a common problem? I looked and looked but just see the transmission flare issues. I like the ES350 and the general direction Lexus is going in terms of design, etc., but that really is dissapointing for a brand new Lexus with less than 5,000 miles on it. The window is being repaired under warranty and re-tinted.

Did you find any other way of reinforcing the strength of the plastic? I read somewhere that someone got rid of the plastic and replaced it with an aluminum tab instead. I don't recall where I read that though.I've also measured all the dimensions of the tab the last time I opened up the panel. I should be able to 3D print it if I chose to but I have doubts the strength of printed material is as strong as the original plastic. It's probably better to have it machined in aluminum...

The reliable way to connect the regulator to the window is to waterjet 2 holes into the glass and mechanically connect the window to the regulator with bolts or rivets. This is how REPUTABLE auto designers operate. This basically lasts forever. Lexus and some low reliability US manufacturers figured out they can save $4.00 per window by gluing plastic tabs onto the glass and mounting the regulators thru these tabs. They also use less glass. The etching compound used to prep the glass to the tab can react with the plastic tab causing the plastic to get brittle and break over time. And/or the plastic tab is formulated with insufficient plasticizer (expensive part of the plastic formulation) which also causes the plastic to get brittle and break. You would think that when you buy a premium car you would get the best design but we got the worst design from Lexus. They are not about to fix all these defective vehicles at $2000 per copy. Our only recourse is to file a complaint at www-odi.nhtsa.dot.gov. The government forced Toyota to do a recall in 2008 for a similar problem on bad window connections on Corollas and Matrix.
