2013 Prius v - "system check" and "map check" with sometimes slow start and need to then reseWindows

Sounds like time to replace the 12 V battery. If you have the chance try to get it checked at a store.

 

Oh, there are jump points under the hood much more accessible than under a full trunk! Please check the manual for where to connect. Positive is under a little red flip cap inside the fuse box. Negative is part of the engine. I am hoping you have access to a manual to find the points in pictures. I’m afraid for now I need to get back to bed....

 

Here are the pertinent pages from the 2013 Prius v Owners Manual...

 

I printed out the under hood instructions and kept them in the glove box for my wife and anyone who might want to help. I too suspect your 12v battery, especially if it's original. Most likely its just good enough for normal situations but does not much reserve. I have attached another version of the jump starting procedure that can be printed (if you don't have a printer, send it to a local kinkos for print).

PS: It's a good idea for everybody to actually open the hood and access the fuse box and the positive (red) jump terminal. It is small so a small cheap pair of jumper cables is a good thing to carry behind the back seat in the umbrella channel.

 

As suggested above, all symptoms of a failing 12V auxiliary battery. Easy fix.

 

High ignition-off current draw? (Further taxes an old and failing 12V auxiliary battery.)

 

I hardly ever go to the dealer unless I can’t fix it on my own I’m afraid.

I was trying to find if the usual local auto parts stores like AutoZone and O’Reilly’s would help replace the 12 V battery for you for free, as I thought some of them do. So far with those two I don’t think O’Reilly’s will if they have to remove the spare tire from what I read on their site. (But I just realized I do not think the spare needs to be removed to access the battery)? It would be more cost effective than labor at a dealer I would think.... I had a friend who decided to use AAA to replace her battery, non Prius though, even though her husband does electrical installations for police departments, and I want to assume it would be an easy task for him.

Other sources are Costco or Sam’s Club if you are a member, or Walmart. I found Walmart has these for sale:

OPTIMA YellowTop Dual Purpose Battery, Prius ds46b24r - Walmart.com

Maybe some who have used it can chime in on whether they are still good like they used to be....

 

Changing the 12v battery is easy and fast. Yes you have to pull up and out some trunk floor panels. No you don't touch the spare tire.

How do I know this, I once had a bottle of wine (red) brake loose in the trunk and smash into another one thus braking. In spite of a Weathermate mat back there, some sloshed over the lip of the mat and into the 12v battery compartment on the right rear of the under the floor. I needed to remove the battery to clean up the spill.

If you pulled out those panels and pulled into Autozone with the battery exposed, I'll bet they would do it in 5 minutes.

 

An Optima yellow is a good choice. Ours is on its fourth year of service in the v, with the CTEK LED battery status indicator.

I previously used the Optima yellow in the CR-V until it developed an internal dead short, and in the sports car, but switched to a much lighter, laydown lithium battery.

 

Changing the battery in a v is no more difficult than in a conventional car. Except if you have the trunk full. Of groceries and melting ice cream in 95 degree sun. You can jump a v via a little box under the hood. Jumper cables fit nicely in the spare tire compartment. Get long one with thick cables. Don't try to jump someone else's car with a Prius.

 

Glad you are home safe and sound!

One other battery to keep handy is the one for the key/remote. We were in HI and first sign of trouble with the rental, a Nissan, was that the vehicle stopped responding to the unlock button while we were trying to find it on the lot. I had to use the manual key to open the door. Later on in the week all of a sudden the dash display started giving key not detected or invalid key, and I couldn’t start it for 4 or so tries in hot weather with chocolates in the back... Would have had to drive to the rental place at the airport, read waste of plenty of time, to swap out the car, instead used the spare we had from my son’s toy and no problems until we returned the vehicle at the end of our trip....

 

When my wife and I go on a long trip, we have the passenger swap their normal set of keys for the set that has the key of the car we are driving. Since she always chooses her car and I mine, it works that we each have two sets of keys. Even better the extra set only has one key and the fob. So light.

Takes care of the battery problem and the Oh sugar I locked the keys in the car problem both. Last thing I want to happen is get back jet lagged from an overseas trip and a fob doesn't work or a battery is discharged. Which is also why I have a great set of jumper cables in each of our cars.
I buy the batteries on Amaz... and buy two at a time so I update both sets and we know her and my other car sets get few uses so they will be fresh when we need em.
