After 7 days finally got 'little red' back this morning - creak could not be heard on the 20 mile drive home - here's what they wrote on my receipt...
CUST STATES THERE IS A LOT OF CREAKING NOISE COMING FROM THE SUNROOF/CHECK AND ADVISE
CALLED GM TECH LINE FOR INPUT ON THIS CONCERN/WAS TOLD TO INSTALL FOAM AND THE STOPS/INSTALLED POWDER TEFLON/SPRAY LUBE ON THE GLIDES AND STOPS
COMPLETEDLUBE THE SUNROOF GUIDES AND STOPS/
ROAD TESTED NO NOISE HEARD AT THIS TIME/
Per the service manager, GM tech is getting a lot of these calls. First fix was installing foam (I don't know where) - didn't work. Second was dry teflon lubricant - didn't work. Third was a silicon (I think) spray lube that seems to have done the trick. TIME WILL TELL!!!
