2022 Mazda Mazda3

The vehicle's Connectivity Master Unit (CMU) / infotainment system has experienced a complete, permanent internal electronic failure, logged by Diagnostic Trouble Code DTC U3000:49 (Control Module Internal Electronic Failure). The main display screen is completely dark at all times and never powers on or responds. The unit is available for inspection upon request. This total hardware failure creates critical safety hazards: 1. Non-Compliance with FMVSS No. 111 (Rear Visibility): Because the rearview camera relies entirely on the main display screen, the backup camera is 100% inoperative. When shifting into Reverse, the screen remains black, offering zero rearward visibility and creating an immediate backover risk to pedestrians, children, and property. 2. Complete Loss of Driver Assistance & Emergency Systems: The permanently dark display eliminates access to active safety guidance, rear cross-traffic visual alerts, parking distance indicators, turn-by-turn navigation, and hands-free emergency communication interfaces. 3. Ongoing Driver Distraction: Operating the vehicle without essential safety/navigation displays requires additional driver focus, causing persistent cognitive distraction. The failure was confirmed via professional OBD-II diagnostic scanning showing DTC U3000:49, which explicitly denotes an unprovoked internal component failure rather than wear and tear. The manufacturer has declined to repair or replace the failed assembly out of warranty.

“My 2022 Mazda 3 is experiencing an ‘in-network malfunction’ related to the vehicle’s internal communication system. Multiple technicians have told me this is an internal vehicle network/communication fault, not caused by wear or damage. The dealer refuses to repair it unless I pay out-of-pocket, even though this appears to be a manufacturer defect in the electrical network system, (TCU)This malfunction affects the reliability of the vehicle’s electronics and could impact safety systems while driving. Mazda has not taken responsibility for diagnosing or repairing the issue, and I believe this defect needs to be investigated, as other owners may be affected as well.”

Car doesn't start if sitting more than 4 days untouched. When i went to the dealer, they informed me they know about the issue but nothing can be done about it. They even told me what the issue was, there's something in the car (they don't know what) that draws a lot of power non stop. kills the battery and some time will get stuck mid ignition. I've replaced the battery a few times as well. It's very stressful trying to deal with it after a 12-16 hour shift at work. knowing it will happened again and again, over and over.

I recently received a warning on the dashboard that there is an airbag malfunction and needs to be taken in to get serviced. The warning continues to appear. This appears similar to a recent recall of 2024-2025 Mazda 3s and CX-30s, but there does not appear to be a recall issued for 2022 Mazda 3 models. I have scheduled an appointment for July 24, 2025 at the Mazda dealership to get my vehicle inspected, but because there is no active recall, Mazda states that I may have to pay for the diagnosis and any repairs. I disagree that I am required to pay for any diagnosis/inspections/repairs.

The passenger-side "airbag off" light does not go off, even with an adult in the passenger seat. This is a US car without an ability to disable the airbag, so this should never happen. We assume this means that the airbag will not inflate in an accident. It happens on about 60% of drives with a passenger, and the dealer was unable to reproduce.
