I've been experiencing this same issue lately. For the last couple of months actually. I've kept the car very local for this reason. I was backing out of the driveway one day and I felt something like the front wheels slip. The lights came on and they stayed on until I unhooked the battery and left it off for about 10 minutes to clear the computer. Restarted the car and it was cleared of the three lights. My wife drives it back and forth to work within about a mile. A couple of days ago I was going to put gas in and the lights were back on. My wife had forgot to tell me they came back a couple of days ago.

This time I'm thinking about bringing it and having it scanned at a local parts store and see what it comes back with.

Keep us updated on how yours does and I'll report back my findings.

I think if y'all search this forum, you will find that a dirty ABS sensor or ring (it mounts on the inside of the brake rotors) is often the cause, and a cheap DIY. Search youtube...

Yes, a bad O2 sensor can cause this as well - if the CEL/VSC warning lights comes on, don't automatically assume something catastrophically bad (if the car runs and drives smoothly). If a sensor goes bad, it can trigger these warning lights. You need to get a OBD II scanner or borrow one from your mechanic and see whats causing it to go off. Don't let any mechanic or the dealership talk you into an expensive ($1000-2000) repair until you can get a scanner to read the error code from the ECU.

I have a 2008 rx400h and everything I've read so far is great info. But there's always a but mine has the vsc light on and it runs fine till you shut off car then it won't start again no good have certified mechanic checking it out he reset all the codes and in less then 5 mins the lights come back on and the car won't start when you shut it off and yes it has a brandy new battery thinking it may be water related and shorting one of the many sensors wish the technology was you could find problems faster like directly to the point oh well if anyone can help yay happy holidays
