afstoll,
You posted the same issue in two locations on the forum. I've taken the liberty to combine them in one thread to keep all responses in one place. You will get less duplication of advice and all advice will be in one place, not only to help you, but also any other member who may be experiencing the same problem.
It looks like you have a significant problem with the fiberglass front cap on your RV. As for your statement about Keystone issuing a recall about this last year. You can go to this website to check for any recalls applicable to your RV.:

Keep in mind that even if Keystone issued a recall, say for Montana RV's, it does NOT include Cougar RV's, so you may find a recall for front cap delamination in one brand, but that won't mean your Cougar is covered by the same recall. It also appears, from your first picture, that the front cap is cracked and glazed. You may have a problem with the actual material leaking water through to the substrate rather than a seam or joint that is leaking. However, it does appear that water has made its way through the fiberglass and has damaged your front cap.
I would think, from the pictures you posted, that your repairman gave you some good advice about what caused the problem. The front seal on most RV's is composed of an aluminum strip that lays over the fiberglass and the rubber DICOR roofing membrane. This strip is secured to the RV with a line of screws and then the entire area is covered with DICOR self-leveling sealant. This sealant is subject to cracking or even completely separating from the strip. This would allow water/moisture to enter the front cap and with heat from the sun, could cause the type of damage you have.
There are several places in the owner's manual that discuss the need for owners to regularly inspect all sealant on the RV, especially on the roof. Keystone recommends that this be done 3 or 4 times a year. I would suspect that your sealant cracked, it wasn't repaired in a timely manner and water got under the seal causing the damage you face.
I doubt that Keystone will do anything under any recall or warranty, but will deny any claim. You might contact Keystone using their website warranty/service link:

I believe your best solution would be to contact a fiberglass repairman, possibly a boat dealer could offer you some suggestions to who, in your area, is a reputable repair shop. Once repaired, I would suggest you start a regular inspection of the sealant on your RV.
You might get some help from your insurance company, but I wouldn't count on Keystone for anything other than confirmation that your RV is damaged.
Good Luck.
