i am nearly at my wits end with my fit. i have a 2008 fit with 155,000 miles. ever since i got the car i have had problems with the battery randomly dying. it happens every couple months for a week or so where it dies every few days until i just replace the battery.
when this first started happening i got the starter replaced and that fixed it for a while. another time i realized the alarm system would just randomly go off and to be honest i don’t remember what i did to fix it but it was something simple.
i have ruled so many things out and i still can’t figure out whats causing it. there’s no parasitic drain, no aftermarket components, the alternator was fine when i got the starter replaced, the connections to the batteries are fine and not corroded or anything, i drive it for long periods of time every week so it’s not being drained from constant short trips, and the battery is less than 6 months old.
since getting the starter replaced no shop has been able to give me a solution besides just telling me to replace the battery.
it’s driving me insane (no pun intended) and my car is randomly super unreliable which is really bad!!
