Complaints by model year
Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.
NHTSA lists 1 recall campaign for the 2025 CX-30 over its history. Campaigns are matched by model and year, so each one may apply to a given car, and its repair may already be done: check a VIN on NHTSA's recall lookup for the open recalls on that exact car.
Mazda North American Operations is recalling certain 2024-2025 Mazda3 and CX30 vehicles. The Sophisticated Air Bag Sensor (SAS) units may set an error code and deactivate the air bags, due to a low battery condition.
Risk: Air bags that do not deploy in the event of a crash increase the risk of injury.
Remedy: Dealers will reprogram the SAS unit with improved software or replace the unit, free of charge. Owner notification letters were mailed July 24, 2025. Mazda's number for this recall is 7525E.
Carmakers sent NHTSA 153 service bulletins and notices that cover the 2025 CX-30, the latest on Oct 1, 2026. They tell dealers how to fix known issues.
The parts they mention most: unknown or other (75), electrical system (62), engine (23), structure (14), power train (13).
NHTSA hasn't opened a defect investigation that covers this model year.
