I had the same issue of not getting any notifications after ending calls through my car's bluetooth system...contacted Motorola and got this response below. I cleared the partition following the instructions and it has been working fine ever since. Luckily I didnt have to restore factory settings...I would have been more willing to restart the phone after each call rather than set up all the apps and settings all over again. Hope this helps.
Thanks for reaching out to Motorola. I’ve reviewed your e-mail and I’m ready to help.
We do apologize for the inconvenience this has caused you. We recommend that you do some troubleshooting:
1. Power the phone off and back on. Unpair the bluetooth device from your phone.
2. Please do the clear partition process. Clearing the partition will remove any temporary files that may be causing the problem, but will not delete your files or settings. Please follow this link for steps:

3. If you get the same result, perform a factory data reset. We use Reset as troubleshooting for major phone issues.
Factory Data Reset is a tool used to remove everything that was imported, added or installed on the device. Keep in mind, when using this feature everything is deleted.
To reset your device:
1. Touch
2. Touch Settings
3. Touch Backup & reset
4. Touch Factory Data Reset
5. Touch Reset Phone
Before resetting the phone, please be informed of the following.
- Reset will require a minimum battery level of 20%. If you're unable to perform a reset, I recommend to charge the phone for 20-30 minutes and try reset again.
- Ensure any personal data is backed up.
