Well, looks like the same thing has happened again. The VSC, VSC off, and check engine lights are all on at the same time. Its been like that since Sunday morning. I went to the Toyota dealership where I purchased the vehicle from and they told me that cataylitic converters needs to be replaced and I would have to take it to a Lexus dealer and the guy also told me that it would be covered under the 8/80K original warranty. If that is the case, should I be driving the car on a regular basis until my next week appointment? Has anyone had this problem before?
