So I didn't post about the incident I had 1 month ago with my 2010 Prius. Before I begin, the car will be 3 years old in July and my lease will be up. It has a little under 9k miles. I don't drive very far, just locally. Anyway, a month ago I had been sick for 5 days and my car sat in my indoor garage for that time. On the 5th day when I was finally able to go out, I went to start my car in the morning and it was completely dead. Well ok maybe not totally dead as the dash flickered, the screen flickered, the lights were dim, the keyless barely worked and the lovely master warning light shined bright! However, it wouldn't start. I tried to get it to start for over an hour and then eventually nothing worked or flickered. Completely dead, and before anyone asks, nope I didn't leave any light on overnight I had to have AAA come and jump start it, and thankfully it did, but without the full hybrid display system working, so the right side of the dash was pitch black, even as I drove to the dealer. Bottom line, the car was at the dealership service for the day and was fixed by the evening. Problem? My battery got down too low, to the lowest of the low and they brought it back to life, so to speak. Easy enough right? Seems like no big deal? They said it was because I didn't drive for 5 days. Well I'd been on vacation longer than that so I didn't really buy the theory, but it was fixed and I was happy. Well, today, a month later, shy of 2 days if you want to get technical, I go to start my car this afternoon and bam! Same exact thing. Wouldn't start, lights flickered, hybrid system wouldn't stay on...etc. AAA jump started it and back it went to the dealership service. Okay so basically I'm about to get a new Prius in the next month or so since my lease is coming to an end. My car is still under warranty but from what I've explained, does it look like I need a new 12v battery?? I do not know how that would even be possible at under 3 years and 8-9k miles, but I guess stranger things could happen. Any idea what is causing this? Well actually I did forget to mention that AAA checked the battery today and the guy said it was perfectly charged So now I have no clue what to think. I'd love to hear from anyone who has gone through this or maybe knows what this is all about. I just hope the car will be healthy until I get my new one! I appreciate anyone's help. Thanks!
