P0A80 Is Here Had I Had P0AA6 Last Month. Check Hybrid System Is Back. Toyota Said Battery Is Bad Block 14 At 15.23V Others At 17VS. I Had The Dealership Fix It Under Warranty But Now Is Failing Again. Prius At 145,383, Miles 145,310 When It Was Repaired Last Month. 12V 11.93 OFF 13.92 ON.
Whatever it may be, the dealer is willing to fix it under warranty. If they put a new battery in already, the problem maybe somewhere else. Let them sort it out for you
It may not even be the battery that's failing, but since they are the Pros, let them tell you what the problem is
unless they didn't replace the battery, a new battery should not fail again in a month. So best to let them address it
You shouldn't do anything to the battery if it's new. It's very suspicious already that a new battery has failed. Let them deal with it
In a perfect world, it wouldn’t fail at all. Did you actually get a new battery or a non Toyota refurb? A feller once got the same code as yours, he had a 2014 with 54,000 miles and swore it couldn’t be the hv battery.
do you have extended warranty? or is maryland a 10/150 state? if the latter, they are supposed to replace the whole battery, and you would have paperwork. if the former, and they actually 'replaced a module' (most dealers won't) anothe module may have failed, and it will probably keep happening. you need a new 12v battery or at least a charge. it is low from not driving. any idea how old it is?
