5/5 Overall
NHTSA 5-Star Safety Rating
Complaints for the 2024 CX-30 are spread across several systems, with forward collision avoidance generating the most reports. Owners describe the automatic emergency braking activating unexpectedly, applying hard braking with no obstacle present, typically on highways or near shadows and overpasses. A handful of airbag-related complaints follow, though the specific symptoms vary across those reports. A couple of owners report seat concerns. Outside the top systems, individual owners mention the push-button start becoming unresponsive on multiple occasions, a sunroof that shattered without impact, and a loose fuel door assembly. One owner describes a broad electrical failure affecting cabin controls including the infotainment and climate systems. The unexpected braking events from the forward collision system are the clearest recurring pattern, with multiple owners describing near rear-end situations as a result.

By System
The 2024 Mazda CX-30 has 3 recalls, the most serious being an airbag deactivation issue where a drained and recharged battery can cause the airbag system to shut off entirely and fail to deploy in a crash.
This airbag concern stems from two related scenarios: leaving the ignition in the "ON" position long enough to drain the battery, or a low battery condition that triggers an error in the airbag control module. In either case, the airbag warning light comes on and the system stops working, leaving occupants without that protection in a collision. The third recall involves the forward-facing camera that feeds several driver assistance features. When that camera malfunctions, automatic emergency braking and lane-keep assist can stop working, and the headlights lose the ability to automatically switch from high beams to low beams when oncoming traffic is present. The loss of automatic emergency braking means the vehicle will not apply the brakes on its own in situations where a collision is detected, and the lane assist failure means the car will not steer itself back into the lane if it begins to drift.
