Faults:

I purchased my Lexus RX300 with 70,000 miles. Now the SUV has 147,000 miles driven. It drives very smooth.

I was in the process of giving my SUV to my father, until my engine light came on. I have it in the shop as we speak. This has been my first issue, and my mechanic says is not a big deal. I hope he is telling me truth. I will keep you all posted.
