Lexus GS 450h: how reliable?

Lexus GS 450h: how reliable? How good are they really? I have a 2006 GS 450h and the hybrid batteries failed. I was told by a Lexus garage they cost €4,500 approx to replace. Nice car to look at and drive but when they fail you won't buy another one - that's if you can sell it. It has 143k miles on the clock only. All I can say is don't buy one with over 70k on the clock. Maybe you have better ideas on this?

Hi Laurence,

Well, to be honest, we don't often hear of any Lexus models suffering anything in the way of major component failure. Was there some major factor, such as physical damage to the batteries, or flooding or something like that? Batteries in hybrids and electric cars are always a concern when it comes to longevity, but Toyota has 15-year-old Prius still running around and their batteries are still working fine. Lexus claims that the batteries are designed to last the life of the car, so I'm suspecting that there's some other factor at play here.
