NHTSA has received 31 owner complaints about the 2024 Mazda CX-30, or 11.1 per year on the road — far fewer complaints than typical (complaint index 0.28, where 1.00 is the average of all tracked vehicles). Among the 89 model-year 2024 vehicles we track, it ranks #19 of 89 by complaints per year (#1 = fewest). Against other Mazda models its rate is about the same; against other Subcompact SUVs it is 51% lower.
