just an update, turns out the car is still covered under Lexus 60 months power-train warranty. So now the dealer has to send the car to Lexus because the warranty company (the one I bought with the car) will not cover the repair.
Eventually this will all get fixed, but in the mean time, I've been without the car for over a month! I am considering trading this car in for a newer ISF but I was planning on driving it for a couple years first.
I think I am going to put it back to factory suspension and get smaller 18" wheels with all weather tires to make it drivable since I live in a big city. The lowered suspension and oversized wheels have been scraping and giving problems anyway.
To add to the fun, none of the electronics on the steering wheel work, including the cruise control so even after this major problem is fixed, I still have at least another claim to put in for this issue.
Basically I will spend a lot of time and energy (and hopefully no money) fixing this car back up to the way it should have been when I bought it. At least I got a good deal I paid around $33,000 for 2009 with under 40,000 miles. When compared to comparable cars I think I did OK.
This has been an adventure, and at least the dealer gave me an 07 Infiniti G35 to kick around in while all this drama has been unfolding. I've been able to continue with business as usual, just not in the car that I was so thrilled to finally own
