My car wont start unless i disconnect the battery and reconnect it , the other day alll the lights on the dash lit up and all the fans came on, and i could not cut the car off , pushing the start button did nothing, this car is just having a episode
Brought my car used and it had a auto starter that i didn't know about so one day i used it and the car did not crank on all the way which caused the engine light to come talking about service vehicle soon (What!!!!!). Then when i tried to normally start the car i could hear a hesitate so i knew it was a battery. Got that changed but the light was still on. Looked in manual and it said the gas gap could be loose after like 30 starts the light went off. I could have went to the dealership but i knew nothing was wrong with the car just don't panic if it happens to you. Give it two weeks if the light doesn't go away then take it to a mechanic
