Draining charge after tire change

Just drive it, its fine. If there's still an issue after a couple days then visit the dealer.

 

The spare tire is quite near the somewhat exposed 12v battery, which is the "little battery" that powers things like your power door locks when the car is off.

However, that's completely different from the hybrid battery pack that is monitored on your system screen. This is also not too far from the spare, but it is not really exposed.

The hybrid pack is actually quite powerful (201 volt, 1.3 kWh), and thus a bit dangerous. Because of that it is reasonably well protected against shorts and abuse, and is built inside its own metal case to protect it. If they managed to short your hybrid pack, your whole car would probably reek of ozone and scorched electronics.

If it keeps discharging, take it to the dealer and have them check the electrical side of the hybrid system for problems (hybrid battery, inverter, etc).

 

i honestly can't think of anything they could have done to affect you hybrid battery. reset your trip meter and watch you average mpg's. also, can you track and give us a more complete picture of the battery meter and exactly how many bars it's showing at different times?

 

Maintaining normal mpg means the hybrid system is properly managing the delicate balance of HV charging versus discharging the HV battery for more power or acceleration. Lower bars generally means the system is using the battery for efficiency and your driving is not providing many regenerative charging opportunities, like going downhill or the use of moderate braking which primarily regenerates energy versus over taxing the physical brakes.. If I park somewhere with the "ready" mode running for 15-20 minutes, the hv battery may go down to 2 bars before the engine starts to recharge, however it will not recharge much before the engine cuts out 5 minutes later. Getting a full charge takes driving and ideally having those opportunities for regenerative charging. When I drive up and down hills and do things like slowing down early for an upcoming red light, the HV battery quickly goes up. If the HV battery is not pulling it's weight, your mpg would likely drop by 10 mpg or more and the normally decent acceleration capability will disappear making you think you lost half your horsepower.

 

^^^this^^^ how long have you owned it?
the battery charge indicator goes up and down all the time. even as low as two purple and as high as all green.
it does ride around 5 or 6 bars a lot during normal driving.
the biggest issue is your first statement about how many bars it's dropping when shut off. more than two is unusual.
