If the customer's vehicle is among the trim levels referenced above it is equipped with a 6-speaker infotainment system and does not include rear door speakers even though there are speaker grills/covers in the rear door panels. MazdaUSA and published vehicle specifications provide the correct information indicating that these trims are equipped with a \"6-speaker audio system\". This is a normal condition of the \"6-speaker audio system\" and current Mazda CONNECT fader function. Rear speaker diagnosis is not necessary as they are not equipped.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11026907-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11026907-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11026907","components":[],"codes":[],"topics":[],"vehicles":[{"make":"MAZDA","model":"CX-30","year_from":2024,"year_to":2026,"match":"exact","vehicle_ids":["2024_mazda_cx-30","2025_mazda_cx-30","2026_mazda_cx-30"]},{"make":"MAZDA","model":"MAZDA3","year_from":2024,"year_to":2026,"match":"exact","vehicle_ids":["2024_mazda_mazda3","2025_mazda_mazda3","2026_mazda_mazda3"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
