What is your question?
When reversing from a cold start (sp. backing up from parking spot in the morning), there is an audible groan associated with a vibration that I can feel in the steering wheel. It resolves after cycling the brakes by pressing the peddle down several times. I have taken my care to 2 GMC dealerships now: 1st stated they could not reproduce the problem... 2nd stated that it was most likely due to breaks sticking because of moisture in my break line. The second dealership replaced my brake fluid and said that the issue had been resolved. The issue has not been resolved. Any advice on how to proceed or thoughts on possible causes? Thanks for any help.
What makes this problem better or worse?
Occurs only when car is cold

This is a rather unique concern that will require *hands-on* evaluation .. Symptoms are too unusual for online diagnosis.. Additionally - it is very difficult to determine the cause of any intermittent failure unless it can be experienced first hand. With that - I recommend leaving the vehicle at local independent auto repair facility for a few days so a technician can test drive it as often as needed to duplicate this issue. Good luck!
Quite honestly I don’t think the dealerships will take the time needed to actually test drive the vehicle until this problem presents itself.. I think you’ll get better service from an independent repair facility.. I’m retired now but it was quite common to test drive customers vehicles until we could determine exactly what they were experiencing - it is impossible to fix this issue otherwise! And yes - sometimes it would take a few days to do so.. For what it’s worth as an online guess - I suspect the problem will be found within the power steering system - OR - the ‘antilock brake’ system - of course other possibilities certainly exist.
