What's wrong?
The Approaching Vehicle Audible System Information Sound Box amplifier is the notification and warning amplifier for the 2024 Mazda CX-90. It controls the outside sound that alerts pedestrians to the vehicle, including the sound used for reverse.
On affected CX-90 SUVs, the amplifier was built without the program software that controls when the reverse warning sound turns on. Because that control software is missing, the reverse warning sound can activate even when the gear selector is not in reverse. Mazda traced the problem to shifts made quickly between park, drive, neutral, and park.
There is no warning sign before failure. An owner is not given a dashboard message or clear symptom that the amplifier software is missing before the outside warning sound operates incorrectly.
Who's affected?
The same external/pedestrian alert amplifier is listed for both back-over and forward-collision warning systems.

What's the safety risk?
Inaccurate external warning sounds can make pedestrians misread the direction of an approaching 2024 Mazda CX-90, increasing the risk of a crash or injury. There is no warning sign before the sound issue. Use extra care around pedestrians and schedule the software update soon. Repair is free at any franchised Mazda dealer.
What should I do?
- Check your VIN to confirm your 2024 Mazda CX-90 is included in this recall.
- Contact a franchised Mazda dealer to schedule the free AVAS ISB amplifier software update that fixes the inaccurate pedestrian warning sounds.
- Bring the recall notice if you have it, or reference recall number 23V553 when you call.
- Drive with extra care around pedestrians until the software update is complete.
What happens at the repair
At the dealer, a Mazda technician updates the AVAS ISB amplifier software so the external pedestrian warning sound works with the required software in place. The recall repair is free, with parts and labor covered by Mazda. Mazda is not offering a separate reimbursement program because the subject vehicles are under new vehicle warranty coverage. If you already paid for related work, ask the service desk how the new vehicle warranty applies to that prior repair paperwork.
