Need help diagnosing please
2024 Kia carnival EX. This issue hasn’t happened to me yet so I’m relaying info from wife. She said the vehicle wouldn’t start for her today. She said the brake wouldn’t even press down like it usually does when you go to start the car. She said it barely would and when pressed start button the screen and AC comes on but car doesn’t start. She said after several attempts the brake eventually went down and car started.
She drove it around and I was at work so asked her to run it to autozone to be tested. She said it tested good but they said that that could be false positive since had been driving around so they didn’t know for sure if battery or not is bad.
Now tonight after car had sit for 5-6 hours it wouldn’t start for her tonight. Same issue brake wouldn’t press down then eventually would.
As far as I can tell nothing has been left on to drain battery.
Only weird thing out of originally would be that she took the vehicle to dealership a few days ago so they could work on a couple recalls. She said since then she’s got a few alerts on the screen saying things she hadn’t seen before. Only specific one she remembers was asking to sync contacts. But also something else she couldn’t remember that she hadn’t seen before.
Any advice is greatly appreciated thank you!
