This is a recurring but intermittent problem with the exact same symptoms as described for non-Corvette GM models in NHTSA campaign number: 14V252000 "the brake lights to illuminate without the brake pedal being pushed; the brake lights to not illuminate when the pedal is pushed; difficulty disengaging the cruise control; moving the gear shifter out of the 'park' position without pushing the brake; and disablement of crash avoidance features such as traction control, electronic stability control, and panic braking assist features." I have noticed that the problem often initiates when driving over a bump, suggesting an intermittent open or short wiring issue. Then later things will return to normal for days or weeks. Chevy dealer first recalibrated the "brake pedal position sensor" then later replaced and recalibrated it; both non-warranty repairs. The problem continues with the next recommended action to replace the BCM at $700+ cost.
