The car was sitting for about 3 months now because out of nowhere it didn’t want to turn on, a month in it turned on fine but didn’t trust it so left it running for a bit then turned it off after 10 min or so, next day car cranked (sounded like impact drill that’s over tightening a bolt) but didn’t turn on after that it didn’t turn on at all, a few days later my hazards would come on for some reason and next day same thing and that’s when I just disconnected the battery (I know I should have done it earlier) the started is 7-8 months old, alternator is about the same and the battery had warranty so I just went and got a new one yesterday and the car turned on like nothing but I don’t want to drive it since I hooked up my BlueDriver and the codes C1241 and C1223 came up what could my problem be ? Car has 117k miles.
Wow you said it started fine with the new battery just had a bad battery hopefully. And those codes like that for communication codes will often trip up because the batteries weak you'll have to go to a guy like me with an advanced scan tool to reset all the communication codes though those things won't go away with the cheap scan tool
One more thing about I that at night in the morning probably around 12 hours later the hazards came on so I went to turn on the car and it turned on ? But I did have the car on jack stands would that be the trigger for the hazards coming on ?
