None of the ES' you mention are affected by this problem. The problem is only found in 1997-2001 Camrys, Solaras, Siennas, Avalons, Celicas and Highlanders as well as 1997-2001 Lexus ES300s and RX300s, so I'm not surprised those older ES' have held up so well. It is a huge across the board issue on the 97-01's. If you maintain your car properly, you'll just see the problem at a later mileage.
I resurrected this only because I am new here and saw it for the first time. Why do I still drive a lexus product? I don't understand the connection. I was merely responding to someone's comment on this discussion- they stated that Ford and Chrysler don't stand behind their products like Toyota and Honda do, and I pointed out how Toyotra and Honda both avoided recalls even though they had acknowledged design faults, so they are no better than the domestic automakers in that respect.
Just because someone has a problem with one aspect of a company doesn't mean they will abandon the company completely- constructive criticism and suggesting improvements is what I'm doing. I was merely pointing out that all car companies do this to some extent, and I believe Toyota could do better. Moreover, I would never buy a lexus affected by this problem- I bought a '97 LX after doing a lot of research. If I had come across a problem like this on the LX, I would never have considered the vehicle.
