Approximately 3 or 4 months since the oxygen sensor was replaced. Fortunately the vehicle is still under warranty. However since this has happened multiple times with my RX and also my '08 ES 350 it suggests perhaps there may be larger issues with Lexus.

2008 RX 350. Re-occuring problem with Check Engine Light and VSC light illuminating. Has been at dealership 3 times for same problem and I believe they have replaced oxygen sensor. Problem reappeared yesterday. Coincidentally my ES350 has similar problem and is presently at dealership for this problem as well as problems with push button star (second time--3 weeks ago they replaced the switch and problem re-appeared 1 week later (brake is firm and when push button won't start. What's up????
