Turn Signal problems of the 2010 Ford Edge

I recently replaced my brake and turn signal light bulb constantly and notice the socket is burnt . So I took it to the dealership I had it replaced. A year later the same instance happen again so I took it to the dealership I had to replace again. I'm noticing a pattern that socket for the turn signal and brake light are burning out.

Rear turn signal lamp and socket melted and burnt. Happened to right side then soon after left side. Replacement is showing signs of melting already. This appears to be a safety issue where a fire could happen. I have seen many complaints on auto forums for the same problem on other models and year.

Rear turn signals keep going out about every 3 to 4 months. Both rear turn signal sockets passenger and driver side.

My rear turn signals have been working intermittently lately and I thought it might be the bulb. When I went to replace the bulb I noticed that the bulb socket appears to be burnt. I immediately went online to see what needs to be done and realized that there are a bunch of other Ford Edges out there with the same problem. I felt it was necessary to report it in case this is a safety issue that could result in a fire. The Ford dealership claims that they do not know of any other complaints, yet when I look online, I see a whole lot with the same issue.

Stop/brake/signal light burned out 1st time just replaced it! burned out 2nd time a year or so later, noticed the receptacle looked black!! burned out 3rd time a day or so later, noted the receptacle looks really black,I got online and found out this is a common problem with this model car !!!. . . . Dealer knows of no recall but I can assure not having a left turn signal in the rear is a real safety hazard !!!! the bulb socket looks as if has almost melted and I think it poses a real danger .
