VSC/Check Engine
My 2007 Lexus RX 350 with about 165,000 miles in it has randomly been showing the VSC Light, followed by the Check Engine Light. For a time, I could disconnect the battery and both would go away. Today that solution stopped working. Is this a sensor issue? Any ideas on cost to fix it? Thanks in advance!

same issue resolved with a new gas cap
I know this may sound like a weird solution, but I would definitely recommend checking out what codes your car is actually receiving.
Mine would constantly throw the check engine and VCS lights.
When I check the codes a lot of them were evap errors and one was a transmission connector error of some sort
None of these really had anything to do with the VCS that kept coming up
I did flush all my brake system using a power bleeder but that didn't resolve the issue and they all came back.
I checked under my hood and made sure all of my vacuum hoses were connected well. One was a little loose and I improved that. And then I bought a new gas cap and a new vacuum solenoid.
I switched out the gas cap first cuz it was the cheapest. And eventually all the errors went away.
And thanks to a recent ice storm up here in Michigan I was able to test the VCS and confirm that it works perfectly
I don't know what errors you are actually experiencing but it may be worth a $10 gas Cap to a start fixing them especially if they're evap errors.
Hope this helps
