NHTSA Complaint #11607954 — 2023 TOYOTA COROLLA

Volume of media from certain apps can't be adjusted. The vehicle says that if media is not playing, the volume can't be adjusted. This can cause distraction while driving and increase risk of a crash. Specific application where this is the case: Youtube audio through an Android Auto connection. Yes it is available for inspection. My safety and the safety of others is at risk, because all Toyota models with this infotainment system function the same way. Drivers may choose to become distracted by their mobile device while trying to adjust the media volume, risking a crash. The problem has not been reproduced or confirmed by dealer, however it would be very easy for me to do so. The vehicle has not been inspected by any party outside of the Toyota dealership. When attempting to adjust the volume, the volume level will appear as a numerical value in the infotainment screen ONLY IF there is currently "audio" playing. If there is no "audio" playing, an error message will appear telling the occupant to begin playing audio to adjust the volume. This becomes an issue when using an app like YouTube to play audio. With YouTube Premium, you can set a playlist of music, videos, or podcasts to listen to with the screen of your mobile device off. However, the infotainment system will not detect the audio the speakers is playing AS AUDIO, and will not adjust the volume. This leaves the driver with no choice but to pay for a Spotify, Sirius XM or Youtube Music subscription in order to listen to music or media and adjust the volume safely. Reproduction: Start vehicle. Start Android Auto. Start playing media through YouTube. Attempt to adjust media volume using the dial or buttons in the vehicle. Error message should appear. Only way to adjust volume is to switch to FM/AM Radio, play Spotify or other app to adjust volume and then resume YouTube media (REQUIRES TOUCHING PHONE), or don't use Android Auto and pay for Toyota GPS. HOW TO FIX: Allow volume adjustment at all times.
