ANALYSISHow safe is the 2021 Mazda CX-30?
The 2021 Mazda CX-30 achieved a 5-star overall NHTSA safety rating, with perfect scores in frontal and side crash tests. Its rollover resistance was rated at 4 stars, with a 15 percent risk of rollover. The vehicle's crash protection sub-score was a strong 66 out of 70. Avoidance technology scored a perfect 10 out of 10, with forward collision warning, lane departure warning, and electronic stability control all standard. However, the 2021 model year's Safety Index rating of 88 Strong represents a five-point decrease from the prior year's 93 Exceptional rating. This decline is largely attributable to the defect record component, which scored 12 out of 20. Two recall campaigns were issued in the same month. One recall addressed a tire valve air-leak risk, a concern also present in the 2021 Mazda3. The second recall involved a power liftgate that could partially lower when open, affecting 2020-2021 CX-30 units. Additionally, 98 unverified owner complaints, primarily detailing engine issues, contributed to the lower defect sub-score. These complaints warrant careful consideration from potential owners.
