You mean you watched it fly off? Is there any adhesive remaining on the charge flap? The badges are not supposed to come off, the adhesive tape that is used is very strong. This indicates defective installation and you should try and get it replaced under warranty, no reason you should have to pay for a replacement.
Like all things Clarity, beauty (and grossness) is in the eye of the beholder. Even before I bought my Clarity I knew the first thing I would do is remove the plug-in badge from the charge flap as I don't like what I consider showroom advertisements on my cars. I wound up removing all three plug-in badges including the one on the rear. My car is on the left in the attached photo. If you look at the Clarity that I am parked next to you can see the plug-in badge above the front wheel well.
Removing the badges requires using fishing line or dental floss to "saw" the adhesive away. Some people use a hair dryer to warm the adhesive, I tried that but it didn't seem to make much difference. It took me about fifteen minutes of sawing for each badge. Some people saw only halfway then pull the badge the rest of the way off, but to me it felt like it could break off if I did that so I sawed about 90% and only then did the badge come off easily. That's why I think yours must have had some problem with the installation if it came off that easily. After removal there was still some adhesive on the paint which I removed with Goo Gone®.
I kept the badges so that I can reattach them when I sell the car. Although I will have to obtain the special adhesive tape that is used for badges, you can't just use regular double sided tape or they will eventually come off. Or I suppose I could purchase new badges which presumably come with adhesive, but I have not priced them.
Did you buy your Clarity new or used? If used it's possible that the previous owner debadged, but then didn't use the correct adhesive tape to reattach it. But if you bought new, in my opinion the badge should be replaced under warranty.
