2010 Pontiac G6 electrical system problems

I bought this car from a dealership called drive now in lebanon tennessee. About 2 miles after signing and trading my vehicle for this one the ESC, tc off, check engine, low tire pressure sensor lights all came on on the dash. I took it to them 4 different times now and they stated to me it's an electrical problem and they claimed to have fixed it!! A month later it all began again.

When starting my car, power steering service ESC was shown on my message center as my car beeped to alarm me of the message as well as I had no power steering and could not turn my wheel. I looked up on the internet what that message meant and saw that there have been recalls for the same issues on previous years of the same vehicle but that 2010 isn't covered under the recall. Online it stated to turn off the vehicle and take the key out of the ignition and then try again.
