All three warning lights came on after driving about 15 minutes. I had noticed some very slight rough idling, especially right after the lights came on, but then after calling Lexus Roadside Assistance and getting the OK to drive the car if I desired and felt safe, the car seemed to drive and idle as well as ever, but the lights are still on. It sounded like they have heard this before. Anyone have any ideas?

Bob, let us know what you find on this. I would also check each of the 4 ABS speed sensors on each wheel. Sometimes these may have some interfeering dirt on them (roads are awfully dirty up here) or a broken lead at a sensor.

Good luck

Ed, well, what should I do when the lights go out??
After a couple days the warning lights all went out. No idea what was going on, I had put the vehicle into a minor skid to try out the VSC a few days earlier, but no other real clues. After the OK to drive her from Lexus Roadside assistance, it drove fine and the slight idle hesitation disappeared too. With the lights out now I am keeping her out of the shop, if you know what I mean. I will report it for a checkup next time in.

If the lights went out - good news. If they stay out - that's better news. If they come on again - we have a problem re-occurring. A one time occurrance might be a dirt problem or such. Repeated warning lights on, I would have it looked at.

Let us know how it works out.

PS, I've been so busy the last 4 weeks, the job has me going atround the clock - hope it slows down soon.

Check the brake fluid level or top it off little bit. Hope this help.
