Black speckles in clear caulk
I am not sure if anyone else has experienced this, and with the other issues I had with my GT 328ts, I was not willing to start that fight.
But the time may have come. The clear caulk all over the RV has black specks in it. I am not sure if it is mold or stuff that was blowing around the factory when they were caulking mine.
Any suggestions would be great. Should I just grin and live with it, or should I go after warranty?

Have same thing going on with 2012 378 but I put it down to the silicone just general aging, debris etc. Had some success with lightly brushing it with soap , water and soft bristled tooth brush but you have to be mindful not to rip the caulking. 2015 is still pretty new to have it happening already unless there's a lot of miles involved - I wouldn't wait too long to ask them about it.

Most likely not, they will say does not affect the product, it is aesthetics only.

I love that answer when they come up with it.
When you buy a ford, chevy or Chrysler and you find something like that they jump to fix it and you paid 1/3rd what you pay for a coach.

I agree but rv industry is NOT the auto industry. That is painful obvious in how they act. It's sad.

I have the same problem in my 2014 335. Looks like only way to fix it is gently dig old calk out and redo it.

Test if dirt or mildew
Greetings! Two things can be happening. Mildew happens if the is a food source and wet conditions. You likely have both in the caulk. On the other hand, as elastomeric type caulks such as silicon, expand and contract with temperature it can embed dust and dirt inside the caulking and it becomes impossible to get out. In both cases, it isn't so much a failure of the caulk as it is environmental conditions.
A good test to see if it is dirt or mildew is to take a little bleach on a rag and wipe the area. Wait for a minute, it the stain visibly changes (disappears or turns from black to light brown), then it is mildew. If so, wipe it with bleach and let it dry thoroughly. You're all set. If it is dirt, then enjoy the 'road warrior, experienced' look. The only recourse if to remove the caulk and start over.
Hope that helps. Good camping!

Removal of sealant
Anyone have an easy way to remove the sealant? I was able to remove the horizontal sealant on the passenger side just above the cargo bay, but the drivers side is in solid. Have tried plastic and would scraper. Not easy....

If it is in solid it is adhering well so why remove it?

I cut it with a knife first seems to help brake the seal then scrape the rest off then I hit the area with 3m adhesive remover before I reapply it.

The reason why I want to remove and replace the mildewed sealant is that if it is mildewed. It by definition is permitting moisture to get under it. While it is "adhering" it is also failing.

what can happen is the installer could use his spit on a finger to wipe the caulk. Bacteria then makes the caulk get black. Not sure of your problem but it is true.

There are commercial removers by 3M and another (I think Dap). Additionally, there are commercial caulk removing tools that is shaped like a corner. Not easy any way to do it.
