So I went to Pepboys for an oil change, I know the mechanic is better but he was very busy. So after it was done I get in the car and start it and theres 4 warnings, an ABS fault, ASPC fault, Emergency braking assist not available and stability control not available drive with care. So I go back in I tell the manager she has the guy take the car back again. So he takes it and then brings it back few minutes after, she asked him if he got the lights off he said there wasn't any when he got in it. Sounds unusual, should I be worried at all or its fine?

 

when he worked on your car the battery may have ran down a bit
