When Upgrade the Premiere CC to the 2015.3 Version, lots of users reflect that all of the .mts files can not be imported while everything worked fine with CC2015.2. In this case, this article comes out. It divided into 3 Part, you can direct jump to the solution, somehow.
Here list some threads from Adobe forum:
1. After update, no more MTS
I just updated Premiere July 2016 which I’m always reluctant to do due to new bugs, the first thing I noticed was all my MTS files are no longer recognised. It says media is offline. Secondly, all my windows icons are now blank. Thirdly, all my historical menu files are from about 2 years ago, WTF?

2. video .MTS not known with upload cc2015.3
When I Installed the new CC2015.3, one problem appeared with video AVCHD: they are not recognized and off line. These rushes have extension MTS
I have to find again these media and localised them to the disk, but I lost the sound track!
With CC2015, I don’t have any problem.
Could you help me please? Did someone meet this trouble?

3. Can’t import spanned MTS (AVCHD) files in Premiere CC-2015.3
I am trying to import (or open a project containing) long video clips, where the source files are Canon MTS files. They would normally be spanned, and joined in Media Browser. I can import and open a short, 4-minute video clip. But if I try to import files that are part of a 2-hour video, my computer freezes up, to the extent that Task Manager can’t open, and I have to do a forced reboot by holding down the power button.

4. Premiere Pro freezes when importing MTS media
Last week, I had no problem with this situation. The files are very big, 4 hours of footage and about 20 Gb, no problem with the import and export, not even a lag at the moment of editing.
But for the past 4 days, I’ve had this problem with the same videos, I try to import them by dragging and everything else but my program keeps freezing and then crashing, I doesn’t happen with other video formats, just the MTS I am working with. I have read a bunch of solutions but they don’t work for me. I’ve tried to unistall and install Premiere, but nothing. I think it had to do with the last Adobe Cloud update, but I’m not sure.

6. avchd files won’t import in PP CC 2015.2 on new mac with El capitan
On my former mac I had no issue importing AVCHD files in premiere pro cc 2015.2
Recently, on my new mac with El Capitan, same version of Premiere pro cc; AVCHD won’t import. Error messages states file format not supported and lists all of the .mts files. No issue importing .wav files.
I am importing correctly from media browser and the file structure is intact as was written to the media card.

If you want to downgrade from Premiere Pro 2015.3 to the previous version i.e., Premiere Pro 2015.2, follow these steps:
1. Open the Creative Cloud desktop application.
2. Click on the Apps tab.
3. Scroll down to the section titled ‘FIND ADDITIONAL APPS’.
4. Click on the ‘All Apps’ drop down menu to the right of the section heading and select ‘VIEW PREVIOUS VERSIONS’.
5. Locate Premiere Pro in the list and click on CC (2015) 9.0.
Note that this will install Premiere Pro CC 2015 (9.0) on your computer, not Premiere Pro CC 2015 (9.2).
6. In Premiere Pro, choose Help > Updates….this will update the application to Premiere Pro CC 2015 (9.2), the previous version.

The step by step guide cite from https://forums.adobe.com/thread/2170895, I am not sure it will work for all the users. You can try the easier method below.
