NHTSA Service Bulletin 10226922: 2022 Mazda Mx-30 Phev
Official manufacturer communication context for 2022 Mazda Mx-30 Phev, with affected products, buyer checks and links into Carchieve recall, problem and VIN research.
Reviewed June 2026 from NHTSA manufacturer communication and service bulletin records. Carchieve is independent and not affiliated with any vehicle manufacturer or government agency.
Some customers may complain that the HVAC system's touch panel switches settings on it's own. When you receive a customer complaint regarding this concern, explain the following characteristics of the touch panel to the customer. The MX-30 heater control unit uses a capacitive touch screen which may determine that a switch has been pressed because of the close proximity of a hand, even though it has not been touched directly. No repair is necessary unless you confirm abnormal operation different from the description. NOTE: The heater control units operation confirmation sound does not sound if there is another warning or confirmation sound of another system at the same time. Since the confirmation sound of the heater control unit is missing in this special case, some customers may feel that the heater control settings have switched by themselves.
