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.
Even though the battery tested fine the problem went when I replaced the battery.
Also, most car manufacturers know that customers are generally bad at doing the "correct" thing, so they protect their batteries by design.
When you are charging to 100% you are actually closer to 95-97%, when you run your car to 0% it's actually 5-7%
All because it's easier to show you another number and build the protection into the system, than to change people's habits.
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.
My Kia EV6 does 10-80 in 18 minutes which is getting close, IMO. It\u2019s certainly enough for me
My 2019 e Niro has done 67k miles and range has not dropped significantly. Over 300 miles suburban in summer and around 230 motorway miles with heating in the winter.
My 2012 recently needed a battery replacement
So on top of cold weather, your battery may need attention
Of course you do. 16-19 kWh/100km to 20-23 kWh/100km. Kia EV6.
My factory battery died at 30k miles on a 2024 corolla…
I bought a ‘24 GT with 5k miles and regret it every day. The battery had to be replaced at 9k miles and we had a loaner for a 5 weeks. Everyday issues like Carplay not working 50% of the time and the backup sensors being way too sensitive drive me insane.
