Hmmm, maybe not as common as I thought. It seems like most I see in Florida have this problem.
At any rate, I just bought two new lids from Acura. I will try to dissect the old ones to see if the leather can be removed and reapplied.
I was going to recommend just buying two lids...my 2011 has been re glued once...I can barely notice it, but my next step will be two new lids...might should do it now while the parts are still around. What did they end up costing you?
Atlanta area here re heat.
Not sure if you guys stumbled across this video before but maybe it'll give you some ideas on a DIY fix?
