general problems of the 2007 Lexus LS460

Multiple failures of air suspension struts. My first was on 9/11 at 50k mile, but 3 months out of warranty. Now, within 30 days is a second failure. Lexus did offer and I did accept on the first that I pay $500 for the part and the would provide labor. Now with the second failure at 30 days on the left rear(first failure was the right rear), I began investigating owners forums, etc. This is a very common and major defect in the Lexus air suspension models. Numerous complaints and multiple failures from 12k miles up on forums. Lexus again offered to provide labor if I would again pay another $500 for part. Lexus by now knows this is a major defect as there are numerous complaints and they readily offer to everybody the same "Lexus participation" offer. This must be deemed a recall as it does involve suspension and ultimately causes unstable cornering. Lexus being able to pass this serious design defect on to the owners is not only deplorable, but should be stopped by your agency. I would appreciate a report with the number complaints filed with this safety problem as my next course of action will be a legal filing. Thank you for any efforts.

I took my 2007 Lexus Ls460 into Lexus of reno for it's 15k mile service on 11. 12. 08. During that service the dealer reported the tires in good condition with 8/32 of tread remaining. On 9. 30. 09 I returned to Lexus of reno for my 20k mile service. I was told that my tires were worn to the cords and that the left rear tread was separating from the tire body. They advised me the tires are very dangerous and I should not drive on them. They reported the tires are now at 0/32 of tread remaining although just looking at the tires the tread seemed to be more than adequate. I was told I did "something" to the vehicle to cause all four wheels to become misaligned. I took the vehicle to a local tire dealer and had all four tires replaced and the vehicle aligned. I did not keep the old tires as I concluded the problem was with the vehicle and not the tires. I do not drive this car hard. If I had done something horrendous enough to cause all four tires to become misaligned I would remember it. I can recall nothing that would have caused such damage. Therefore, there may be something wrong with the vehicle.
