Not sure if this is right category for topic Within the last month or so I have noticed the battery icon shows the battery where the blue is below the charge line, almost zero. As we drive the blue slowly climbs up to where the charge line is. Also we are no longer getting the driving range of a full battery, even on a good day of no heater or any accessories that rely on big battery. Used to be 22+ miles, now lucky if get 14 miles before ICE kicks in. Wondering if Toyota can do a big battery load test, or is it time to think about a new big battery?
how many miles? can you post a pic of the charge icon? are you aware of winter effects on range? tech stream can certainly do a load/capacity test on the battery, but without any dash lights, they are just gonna call it normal degradation. a new battery might cost more than a new car, better to live with it imo.
If it is an old battery, 3rd gen. You could have a person who knows how to get into the hybrid battery and test each cell. I had mine checked and found a few cells that were bad and had them replaced/balanced. Fixed the range of the battery.
I checked with my Toyota dealer and they said not to worry that if something is wrong with battery or charging you will see error light(s) and/or message. Does not give me alot of confidence.
