Any idea of serial number vs build date? How can I tell he build date? And this was rectified in later models? Thanks for the input....
At least with respect to the 60D I don't believe there was an "official" recall, just a policy that Canon would take care of things if the camera was returned for the issue. Some people had an outright replacement of all the rubber at no charge and well past warranty. A few seem to have paid a reduced amount for the repair. Perhaps the overall condition of the camera enters into how Canon treats the owner.
With respect to the T4i however there was an "official" recall due to a white residue on the rubber grips that some people found to be an irritant. A very specific line of serial numbers was mentioned as I recall.
By the way with respect to the repair of peeling rubber parts...many people recommend double backed tape which is the original product. I have repaired rubber components (not my 60D which is holding up well) with one of the Loctite or 3M products available in auto stores for attaching rubber seals to metal car surfaces. You need a product that when cured retains some flexibility. Gorilla glue hardens rigid, expands when curing and in time will crack. The 3M product is called 3M Super Weatherstrip and Gasket Adhesive, about $4 at an auto store. It is black. Just use care when applying (avoid excess) and hold in place with duct tape or electrical tape until cured. This is the 3M product description.
My one reservation is in this thread someone mentioned holes under the rubber grip that would possibly seem to allow a passage of adhesive into the internals of the camera. I would still prefer the adhesive but would likely place some thin double backed tape in the immediate area of any hole to both cover the hole and provide an adhesive property.
