Have checked Key FOBS', as I thought I may have a dead battery 'in the FOB', but my FOB and wifes' acting the same when starting the car.

Went to Hyundai dealer to make an appointment, but the earliest they can get my car in is Oct 31. They said they only have 2 Techs that can run the diagnostics machine and they have soooo many appts for this service they're 'booked out' ! Mechanics said a 'bad' main battery will cause my type of conditions. They said a bad battery will light the Dashboard like the 4th of July!

I ran a volt meter on my battery, and it indicated 12.1 volts, according to my research, that is about a 50% charged battery !

In the meantime, I'm going to call AAA to come to house to test battery, with their equipment. If they say it's basically on its way out I'll have them replace.
Battery is OEM and 5 years old !

Will circle back, after more tests.....

Try jump starting it. Sounds like battery is bad or corroded loose battery cables.
