The interior ambient lighting does not turn off with the rest of the vehicle. If the car is left unlocked and plugged in, but the radio and all other accessories are turned off, the ambient lighting will not turn itself off occasionally. To force it to shut down, we have to hold the radio power button and then exit the vehicle. After a short delay, it will usually turn off. Rather annoying because while it's not consuming that much power, if we left the vehicle for an extended period, it could potentially drain the battery.
