I am having problems for 3rd time with Check Engine Light and VSC. Has been to dealer and i believe they replaced oxygen sensor. Problem appeared again yesterday (and no I have not filled up recently). Interesting my ES350 is currently in shop for same problem along with push button start (replaced 1 week prior) before problem reappeared (brake is firm and won't start when button is pushed). Is this a inherent problem with the 2008 models?

 

Well time to bring it in again...sorry. Or else try another dealer.
