NHTSA Complaint #11587445 — 2022 INFINITI QX60

Safety issue with the Ringtone volume in the infotainment system while connected to Apple Carplay(not Bluetooth). The Ringtone volume setting is being adjusted(unwillingly) along with the call/media volume while in a phone call. Because the call volume has to be increased to a high level in order to hear the conversation, the Ringtone volume will be unintentionally increased at the same time. This cause a dangerously loud ring when a new call comes in due to the Ringtone volume stay high after the previous call. The Ringtone volume can be manually lowered after each call, but the loud ring still occur while adjusting, and defeat the purpose of such hand-free system. This issue cause a jump-scare every time a phone call is received, which could lead to an accident in certain situation. Repro steps: 1 - Start the car and let Apple Carplay connect automatically. 2 - Ensure the Ringtone volume is set to the minimum via the car's infotainment. 3 - Make a phone call using the connected phone. 4 - After the call is ringing/connected. Increase the call volume using the infotainment system's volume knob. 5 - Go back to the car's infotainment system and observe the Ringtone volume has been increased unintentionally. As I research the issue on the internet, the exact same concern has been reported and escalated to Infiniti/Nissan. There has been no resolution for the past 2+ years since the car has been on the market. Example: [XXX] resolution with my experience: Infiniti/Nissan can issue an over-the-air update and automatically set Ringtone volume back to the minimum after each call(via Apple Carplay, NOT Bluetooth) is completed. But many updates later, this issue has not been addressed. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
