2021 MAZDA CX-30 Complaints
The climate control system suffered a sudden, complete failure due to an engineering defect documented in Mazda Technical Service Bulletin (TSB) ID: MC-10203760-0001. The factory evaporator core leaked refrigerant rapidly starving the A/C compressor of essential lubricating oil. This caused the compressor to overheat and complete seize. This failure occurred during extreme summer heat exceeding 100 degrees Fahrenheit, creating an immediate health hazard inside the cabin during my daily 40-mile highway work commute. Additionally, the complete loss of climate control functionality compromises the vehicle's defogging and defrosting capabilities, creating a severe visibility hazard during sudden weather changes on the highway. Mazda customer service corporate teams refused to cover or reimburse the repair because I had to utilize an independent repair facility (Firestone) within walking distance of my home to safely remedy the immediate environmental hazard. The manufacturer is actively denying financial accountability for a well-documented manufacturing flaw that leads to premature secondary component failure. No warning lamps, messages, or other symptoms of the problem prior to failure. First appeared 7/23/26.;
2021 MAZDA MAZDA3 Complaints
My rear differential case cracked, anytime the four wheel drive system was engaged the entire drivetrain would lock up. Luckily we were only on side roads so going less than 30 mph if we had been on the highway when this happened we could have been in an accident or lost control. The dealer did confirm the problem and it was fixed under an extended warranty. There was no warning just all of a sudden a loud bang and all the wheels locked up. I have a copy of the video inspection done at the dealer if there's anyway to send that. I can get a copy of the repair invoice if needed;
