GX470forKC

My 2006 GX470 brakes suddenly went completely out and all the lights came on (Brake, ABS, VSC TRAC, VSC OFF, and some car with squiggly lines symbol light) and a buzzer was sounding, when up to that moment the brakes were working perfectly. Is this a common problem? And what is the likely solution as well as cost? Should I have a Lexus dealer do the fix or any mechanic?

It's either a massive leak from a busted brake line or you electronic master cylinder died. Lexus will be expensive, try to find an import specialist mechanic. Ask around most areas have a Toyota tech that opened his own shop.

Agree. Most likely the brake booster pump. About a $1800 repair.
Seldom happens, but when it does, it isn't cheap.
