My 2012 Eos has traction control and flat tire warning light coming on,

No the lights went off after I restarted the engine, they said that they didn't show any faults on the computer , so they don't know what caused it , so they can't fix it. also the car has a keyless ignition and now the dash shows key not in range when its in my pocket, so I can't start it, sometimes its as much as 5 minutes before the car will read the key, the battery is new. This car is cursed !

Sounds like you need to speak with someone at the dealership that will work with the car and you , until the symptoms can be duplicated , don't take 'no' for an answer! Also do you have more than one 'key'? Also try unplugging any power adapters/chargers just in case they are causing interference ...Becoming a more common problem with all the wireless devices.
