The main issue currently facing Mazda is rusting of vehicle components, particularly the corrosion of the air conditioning expansion valve gasket in the Mazda 3 Axela models. This problem is most prevalent in 2020-2023 model years, accounting for up to 56% of complaints. Owners report that even during normal operation without water exposure, the evaporator pipe head gasket still develops abnormal corrosion, compromising the air conditioning system's functionality. While the 2024 model has adopted more corrosion-resistant aluminum materials, earlier production models require resolution through dealership-provided complimentary inspection services. Other reported problems include electrical equipment malfunctions, body corrosion, and airbag/seatbelt retractor failures. These issues are primarily concentrated in the Mazda 3 Axela, indicating the brand needs improvement in component durability and quality control.
