Is there a fix? Manufacturer service bulletins

The failure pattern owners describe
The dominant problem: the fiberglass roof panel separates or completely detaches from the convertible top frame while driving or during towing. Owners report the separation happens without warning at highway speeds (35 to 72 mph), with some cases occurring at lower speeds. One owner heard wind noise and a brief "road noise" sound near the rear-view mirror just before the panel separated at 70 mph in heavy rain; another received wind noise complaints from the dealer about a worn seal before the panel cleanly separated the next day at 72 mph.
One owner was being towed to a Cadillac dealership when the roof flew off. Another discovered the roof had separated only when inspecting after believing the seal was broken. One report mentions the convertible top fiberglass panel "cannot drive car with top up (closed) as it will most likely detach at highway speeds." Owners cite adhesive failure as the root cause—the glue holding the panel to the frame is giving way. One owner paid $759 for the roof panel and $550 for installation at a Cadillac dealer. Another complaint involved a weight-restriction disclosure issue unrelated to roof separation. Owners note similar recalls exist for the Corvette, on which the XLR is based.
Failure modes owners describe
Roof panel separation/detachment from convertible top frame
Fiberglass roof panel separates or completely detaches from the convertible top frame structure while driving, during towing, or with the top in closed position. Failure attributed to adhesive breakdown.
When: Occurs at speeds from 35 to 72 mph; one case at 100,000 miles; another during towing; timing/mileage unknown for most reports
Symptoms owners cite: Wind noise and air noise near windshield seal or rear-view mirror area (precursor in some cases); Brief 'road noise' sound at roof line before separation; Loud bang and heavy wind noise upon separation; Roof panel visibly separating or completely detaching from frame; Panel found loose or dislodged; convertible top cannot be safely closed at highway speeds
Repairs/costs cited: One owner paid $759 for roof panel replacement and $550 for dealer installation at Vera Cadillac Dealership
Recalls/TSBs owners mention: Case number 8-42070007824 opened by manufacturer for at least one report; one dealer suggested silicone caulk as temporary mitigation but no recall issued. Owners reference similar recalls for Corvette (model the XLR is based on) but no recall issued for XLR.

Cadillac xlr roof separation: I was driving a 2005 Cadillac xlr south of I-75 when the roof suddenly, and quite unexpectedly separated at approximately 70 MPH.

Wind noise near the seal between the windshield and the closed convertible top.*cw the dealership stated it was probably a worn, old seal where the top closed and no action other than applying some silicone caulk at some point in the future would reduce the wind noise.
