Battery Change Is Killing Me

[sad2390]

Car struggled to turn over this morning, started twice and then dead. Jumped it and took to store to get a new battery (haven't changed it since I got the car in 2022). Battery connected and car wouldn't start. Guy at store recommended jumping it, which started it and now I am getting error codes up the wazoo - Thought they cleared out and the car started on its own, but now back to square 1.

Got about 6-8 codes;

1) smart braking system
2) engine
3) sensor system
4) EPB


When the car DOES start, the check engine light is on and the only noticeable issue is it is slow on the uptick when I accelerate. Once it's driving, it seems normal.

I tried the parking brake and that did make an unusual screech, but I was able to release it.

Is there anyway to fuddle my way out of this, or is it straight to the mechanic?

Thanks,
Stephanie

Is this a 2022?

What kind of car do you have? Do you get any CEL ( Check Engine Light)? Regardless, connect a scanner on the car, see if you get anything, any codes. How old is the car, do you have any maintenance history on it? I would start from the spark plugs. Do a visual inspection on them, maybe you need a new set. Check the start push button, maybe you need a new one. Start from here if you don't have any other ideas so far.

If the CX is a '22 I seriously doubt that it needs new plugs and I'm somewhat surprised that it needed a new battery. I'm still on the OEM from 2016 and still starting the car just fine.

Some, or perhaps all, of those error codes will clear once the car gets started and moving.

I would, too, but he said he got the car in 2022, not that the car is a 2022 model. Maybe I misunderstood.

Nope, you're right. The OP said that the car was acquired in 22, I'm assuming that it's a 2022 but of course, I could be wrong. That's the only number that I have to go by, so...

Probably not a 22 though, since the OP didn't mention warranty.

Is there a possibility that disconnecting the battery again to clear the codes would help?

There's a possibility you got a bad or discharged battery.

Yeah, maybe it was sitting a little discharged on the shelf.
