When I was driving my Lexus GX470 (2003) with my family on a local street at around 35 mph, my vehicle suddenly stopped by itself. The brakes engage by itself and the vehicle stability control activated with beeps. Fortunately, no one was behind me. I took my car to the local mechanic, he checked the brakes, calipers..etc, he said everything is fine but he couldn?T find any reason why it happened, he asked me to contact Lexus dealer. I called the Lexus dealer service center, I explained the service representative about what happened, he told me to check the brake calipers, I told him the mechanic already checked it. Anyway, even the Lexus dealer couldn't explain why it happened.
