2016 Lincoln MKZ - Weird Electrical Stuff

Car wouldn’t start. Then tried horn and it wouldn’t shut off. Seats wouldn’t adjust themselves. Then I tried to start it and it worked.

Ask your shop to do a basic battery and alternator test. The diy’er method is: Before first start of the day the battery should measure about 12.6 volts. Immediately after starting the engine, 13.5-15.5 volts. If you diy’er’ed it, report what you measure here.

It sounds like a short time but maybe the battery needs to get checked.
