You might also check the 12v battery, if it's limping along on the original or a dead one it would have to be constantly recharged by the HV battery & inverter running more often. Our 2013 had the original battery still in it when we bought it a couple months ago, clinging on at 11.9v. Mileage seems to have improved slightly with a fresh one.
I have a 2016 Gen 4 that my partner commutes about 100 miles round trip in. Aside from its strange looks it's a great car. Zero repairs so far at more than 220K miles. No rattles or clunks. Every single electric button and switch still works.
I personally use Samsung 50S and RS50. The RS50 or 50XG are the optimal choice in my opinion.
I did the same replacements two weeks ago, it took about a week for the battery to recalibrate, definitely am seeing the improvements now.
Not a Lexus but 2023 Camry and had my battery die twice and both times had Toyota test it and charge it.
It was from lack of use, and short drives. The battery was also on the low amp of cca ratings. I replaced it with a much stronger CCA rating battery and haven't had any issues,
My 2012 recently needed a battery replacement
So on top of cold weather, your battery may need attention
Assuming that it's a hybrid and not a PHEV it should run you about $2,500 to have it done professionally, or less than $1000 to do it yourself. At least that was my experience with my Prius.
My factory battery died at 30k miles on a 2024 corolla…
Looks like I'm getting a battery replacement. Very disappointed in Samsung this year.
im on my second tablet a9 the first wouldnt charge after a update now its not charging again this model has problems with thiere batterys
