Hybrid battery not holding charge

you need a dealer, or someone with toyota tech stream diagnostic software

 

Seems like you have a failing hybrid battery, needs a replacement.

you can try force charging it as a temporary band aid. Put it in drive and hold the brake down with your left foot. Fully depress the accelerator with your foot, this will force charge the battery until full. Repeat this a few times (drain it by letting the AC run on high). Force charge when it gets low.

This is just a band aid to buy you time to save money for another battery

 

Sounds like you may have a failing inverter pump Do you know where that is You know it's supposed to be running when you like open the door to the chiropractically anyway turn the car on get out open the jug next to the silver hybrid synergy drive inverter with the writing on top of it Do you see the coolant moving Is the coolant that the full mark there's a pump right behind the headlight of the driver side It's on a gold bracket put your hand on it Do you feel it vibrating see the two hoses coming in and out of it squeeze them You hear the pump change tune when you squeeze the hose? If the reservoir is a little low top it off If you don't see coolant moving in the jug that is a good possibility that is a problem that'll let your inverter get hot and then it throttles back or doesn't charge the HV battery maybe have a look good luck.

 

It could be the inverter water pump OR one of many other things that is triggering the warning lights(trouble codes). You need to get the trouble codes read. Most scan tools can not communicate with all of the 12 or more ECUs in the car. You need a better mechanic or a Toyota dealership to retrieve the trouble codes.

If you want to DIY, you can buy a good scan tool like the Autel Maxi AP200 as reviewed in the thread linked below.

Who replaced the HV battery, and was it an OEM battery?

Welcome to PriusChat!!

A new OEM battery installed by a toyota dealer gives you have a three (3) year warranty. If OEM and otherwise, then only one (1) year.

I just replaced My HV battery about 11 months ago. Was about 1488 ordered online through the largest Toyota dealer in my area to get the online price you've got to order online or you get charged retail almost double this is me picking it up at the parts department dropping off my old battery and taking the new but it had to be ordered online as the catch to get the lower price.

 

That $1488 price was a one-off special price not likely to be repeated, Tom lucked out there.

 

I thought some guy just said he paid similar to that not too long ago maybe it was 16 or 18 but anyway that was the price when the pandemic started at Rick Hendrick Chevrolet I don't know much else I don't know if it went up during the pandemic maybe after because I think I checked I don't know a year into the pandemic when all the crap was on the fan. And they told me the salesman at the parts department do the same thing again Mr deramus and everything should be good and then I went and got the battery from the hybrid doctor in Virginia instead for like $700 and that battery still running top-notch driven everyday and back and forth to work.

 

didn't the hybrid doctor retire during covid?

 

Geez I don't think so He's got a bunch of people working for him and those cars with logos on them somebody's running the place He's from South America real nice guy matter of fact I need to give him a call so I'll probably find out shortly and I don't think so.

 

if your battery is not charging, then you have some major issues going on. MG1 and MG2 in the transaxle responsible for your lack of charging to the hybrid battery. You will definitely have codes for this type of failure.
