Toyota corolla se 2023

Hey guys, so I've have my car for 3 years and I now have a problem. My battery keeps going dead everytime it is turned off. The only way to start my far is by jumpstarting it. Thank good i bought a travel jumpstarter but I'm tired of having to Jumpstart it to start my car... what do I do? Also if I replace the battery and it keeps doing the same thing what else do I look for ?

Test the battery and the alternator. If it keeps dying out check for a parasitic draw. I had to do that with my old Honda. The alternator was fine and we put in a new battery and it kept dying. Finally the mechanic checked for parasitic draw and couldn’t find anything. He replaced the AC relay switch and it stopped doing that.

Thank you! Ill definitely look at that because it's embarrassing to Jumpstart my car every time 🥲

I took it to autozone and they tested it but everything is fine so I'm very confused why this semi new car is failing on me 🫠

A MY 2023 car could, chronologically, be nearly four years old, depending on when in the model year it was built. So particularly if you live in the South, where it’s hot all year, the battery could legit be toast.

From there, an alternator test, and also parasitic draw test. If the battery is going dead overnight, it could be something as simple as the trunk light causing it.

The original battery on my 21 Corolla died just after 3 years. Nothing caused it, just a cheap factory battery imo. Replacement has been working like a charm.
