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.

Pros: Mileage seems improved

Cons: original battery was dead

Vehicle: Toyota Prius

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.

Pros: Zero repairs, great car

Cons: strange looks

Vehicle: Toyota Prius

Mileage: 354000 km

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,

Pros: no more issues

Cons: battery died twice

Vehicle: Toyota Camry
