In answer to your question, the bell ring happens when the brake warning light comes on. It is the same one that occurs if the brakes need servicing.
There is NO PATTERN to when these lights come on and off. Sometimes they occur when the ignition is turned on, sometimes they occur during driving, they usually turn off one at a time but generally come on all together. They can stay on for a few hours or a few days.
The dealer who performed the tune up and brake job, the GM dealer in Oakland, CA, is aware of these problems and tried to "re-program" the onboard computer the last time the car was brought to him with these complaints. That did not fix the problem.
