5/5 Overall
NHTSA 5-Star Safety Rating
Engine complaints dominate the 2021 CX-30 owner reports, with the most common scenario being the vehicle losing drive power while the engine continues running, owners describe pressing the accelerator and getting no response, with a dashboard warning indicating an engine malfunction. Some report shutting the car off and restarting multiple times without restoring movement. The forward collision avoidance system draws the second-largest cluster of complaints, where owners describe the front camera disabling itself during normal driving, taking automatic emergency braking, lane-keeping assist, and adaptive cruise control offline with it. A smaller but consistent group of reports covers visibility, primarily sun visors that sag from the retracted position on their own due to a broken attachment point, which owners say creates a glare problem in direct sunlight.

By System
The 2021 Mazda CX-30 has 3 recalls, the most serious being a tire valve stem defect that can cause sudden or gradual air loss while driving, raising the risk of losing control of the vehicle.
The tire valve stem issue stems from damage that may have occurred during assembly, and because air loss can happen suddenly rather than gradually, a driver may have little warning before handling becomes unpredictable. There is also a structural concern with the power liftgate: when the vehicle is parked facing uphill on a slope and the liftgate is fully open, it can drop down unexpectedly without warning. Anyone loading or unloading cargo from the rear of the vehicle at that moment could be struck by the descending gate.
