I have a 2012 Prius and this sucker needs a professional eye to take a look at what's going on with it. After replacing the battery a few months ago, my "ready" light is still having issues turning on. I've disconnected and reconnected the negative cable on the 12v battery whenever the issue happens, but I can't be doing that all the time. plus, the car has been averaging less than 35mpgs, and the EV doesn't turn on when it should, even after a substantial warm-up time. I feel like this prius is just getting worse and worse, and I'm only at 95k miles. I thought this thing is supposed to last forever! Anyways, anyone know of a good and honest shops in the Los Angeles/Hollywood area?
avi's advanced automotive in tejunga. great guy, very knowledgable, and he is a member here. you're fortunate to have him in your backyard. all the best!
In your shoes, I would measure the 12v after overnight with a multimeter from engine jump points first. If it's lower than 12.7v then you can hit the panic button.
the Synergy drive system warranty in CARB states, like Cali, is for 10yrs - 150K miles - not "forever". So - since you're still under warranty, what's the big deal about going in & having the precise issue determined? .
the only big deal is that I'd rather not deal with it and just have a fine working machine out of the box. But that's not the case, so now I'm on a prius forum to find a professional to look at it.
Thanks for the response! What would it mean if it was below 12.7v? Also, I'm not sure what you mean "Engine Jump Points" - is that somewhere else other than the battery connections themselves?
in the owners manual, you will find instructions on how to access the emergency jump start point located in the fuse box under the hood. this is easier than accessing the 12v terminals in back, and if the battery is dead, much easier than climbing into the hatch from the rear seat because the hatch door won't open if the battery is dead. pop the hood after finished driving for the day. the next morning, put a volt meter on the jump point and a clean ground bolt in the engine bay. it's not scientific, but if it is below 12.4, the battery might be getting weak. or you can go to an auto parts store that has a load tester and will give you a free printout on the 12v health.
Avi is at hybridfix.com, he's next to USC Your car should still be under warranty in CA, so if your 12v battery connections are good and tight, I would just bring it to the dealer. But it's most likely your 12v connection not tight
