You need a mechanic with experience with Lexus cars----. May I revise that slightly....? Mechanic implies "wrench" and that does not "fit" the process of troubleshooting these modern day cars, Lexus or no. So the "proper" statement might have been.... You need a GOOD, HONEST, technician for troubleshooting... Now that we have given you the easy part the hard part is up to you......FINDING ONE. Ask around amongst your friends.... Oh, typically they do not "reside" at dealerships. Oh, yet another thing... Autozone isn't a bad place to start, knowing the codes will at least give you an edge up on the dishonest "mechanic" that tries to oversell the repair. I went to AutoZone this morning. The guy told me to hit the VSC Off button to turn the light off. It went off. He said, that should take care of the problem. I left and that took care of it. I had tried to turn it off before when it went on, but it wouldn't go off. He said the same thing that you did that it was probably the battery. I just replaced the battery less than a year ago. I don't understand if the battery is bad, why does it start the car right up? Thank you for your reply. I know that I need to find a good Lexus technician. Eva

I have a 1999 LS400 with 67,000 miles on it. I also am having the VSC Off light and the CEL come on at the same time, the Check VSC error message comes on and I my car dies. It does this when I let off of the gas, like when I am going around a corner or through an intersection. It is very scary. This happened one time last year and I called the dealership, the mechanic told me to make sure that my gas cap was on very tight. I tightened it and the problem went away. Now it has happened several times over the last few days and today when I was driving home my car quit 5 times. I have to pull over, stop the car, turn it off, then turn it back on, and put the gas to it right away to keep it running. I called a local mechanic that replaced the brake sensors on my car a little over a week ago. He said that it was a problem with the transmission. That didn't make any sense to me at all, although I must admit I know very little about the mechanics/electronics of this (or any) car. I am a pretty quick study though and want to understand it before I take it in to either the dealership or another mechanic so that I don't get taken advantage of. Per the suggestion, I will take the car over to a local AutoZone tomorrow. I have two questions. 1. What is the cause of this problem? 2. Could the mechanic that replaced my serpentine belt and brake sensors last week have contributed to this problem? Thanks so much for having this great forum.
