We are new owners of a 2021 Pacifica Hybrid & are really happy to have found this forum!
For us, we definitely need 2+ profiles to accommodate the different driving styles and preferences. For example, for the older family member profile, we intend to configure the safety settings to trigger faster, louder and be more prominent. For the younger drivers, we will include profile settings that are not as loud and aggressive, plus things like stereo settings, tilt mirror on reverse, etc...
We are very disappointed that FCA dropped the ball on this; this vehicle shouldn't have gone into Production with such software defects especially if the User Manual describes the behavior one way, but the purchased product doesn't honor what's written; in the software industry... the teams/managers responsible for major blunders like this would be let go. One person put it perfectly in a previous post - the software on this vehicle reminds them of an old Windows operating system.

It's frightening to think what other software safety-related issues/defects are out there.
Question for the forum, when an OTA update occurs, how can you tell? Is there a notice of some kind or it just happens silently?
