Not sure if this is the right place but I'm having trouble with my 2017 Ford fusion hybrid se.

Symptoms Rotten egg smell in car after driving at 65 mph for awhile Sync system is displaying message that it needs to shut off to conserve battery and to shut off ignition Autolocks are not working correctly

Car is working fine otherwise. Starts up like normal, there is a slight delay on the digital dash but not significant. The battery light is not on nor is there any other indicator lights. Not even a check engine. The battery is original from when the car was manufactured I think based off the serial number. I might be misreading that though. Taking it into the dealer just wanted to see if anyone else had experienced something similar to potentially avoid being screwed by dealership.
