When my wife left for work the car displayed an SRS/airbag warning on the dash. It was running so she decided to go to work, but turned around after a few miles when she realized all of the driver assist systems were also disabled. When she got home I checked the battery voltage and it read 11.8 volts (I also read the DTCs, and pulled B1AC0). After charging overnight the error was gone. This vehicle is driven almost daily, was delivered to us 3 months ago, and doesn't sit with the ignition on draining the battery (my short way of saying there no behavioral or maintenance related reasons for this to occur). I have been monitoring the battery charge after drives now and putting it on the charger every night. It appears the car is chronically undercharging the battery--a known issue going back several years on RAV4 hybrids (layperson analysis here: [XXX]) INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
