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.
Starts fine even in -4F weather. Will probably swap it this year with another OE battery as oddly i have better luck with OE batteries and they tend to be cheaper than Autozone/Orielys/Advanced.
2017 got a new battery in 2023 before winter, didn't have a no start issue but figured it was time. Went with a dealer battery, was only $138ish for the 72ah upgrade and replaced it in their parking lot to get the core charge back.
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.
Update: it was just the battery, everything works fine after replacement and coding/adaptation. No error codes. Thanks everyone
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
I’ve had my id3 5 years now and had very few problems with the car or charging. I’ll get maybe 180 miles on the motorway but close to 240 miles cross country. Manchester to Sheffield to Nottingham and back to Manchester left me with around 50 miles range, but I can’t get from Manchester to London, or Manchester to Glasgow without charging.
My factory battery died at 30k miles on a 2024 corolla…
2022 ID.4 in Canada. Have had two replaced. Luckily when it happened it was in my driveway for all three times. Hooked up a charger to the 12v for a few hours and it started like nothing was wrong.
