Service bulletins for the 2019 Mazda CX-3

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

MT-006-202020-12-03. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY; ELECTRICAL SYSTEM. Some customers may complain about the following MAZDA CONNECT™ Temperature Warning message: • Display is too Hot. Screen performance may be decreased until it cools. The warning message displays when the MAZDA CONNECT™ screen temperature is above 176 degrees Fahrenheit (80 degrees Celsius).
MT-004-202020-12-03. Service bulletin. EQUIPMENT; FUEL SYSTEM, GASOLINE. Some customers may complain about a tapping or knocking noise coming from the rear seat after fuel fill. The concern will likely occur if the fuel tank is overfilled (more fuel is added after the fuel pump nozzle shuts off automatically) or filled up normally in high ambient temperatures and the fuel expands.
09-036-20-37562020-12-03. Service bulletin. ELECTRICAL SYSTEM; EQUIPMENT ADAPTIVE/MOBILITY. Some vehicles may exhibit a Connectivity Master Unit (CMU), a BLUETOOTH® hands-free unit or text messaging related concerns. To improve the handling of BLUETOOTH® hands-free and/or text messaging customer concerns, Mazda created a special service and parts exchange program as of February 2010.
04-007-20-3713a2020-12-03. Service bulletin. PARKING BRAKE:ELECTRICAL; SERVICE BRAKES; EQUIPMENT. Some vehicles equipped with electric parking brake (EPB) may exhibit a grinding noise from the rear brakes when braking. This may be caused by the rear brake pads not having the capability to remove the rust from the rear brake discs. The red rust accumulated on the discs is exposed to high temperatures during braking, and consequently the rust turns black. As the black rust is too hard to be removed by the brake pads, the rust progress is accelerated, resulting in the grinding noise.
SA-047-20a2020-11-04. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY; EQUIPMENT; ENGINE AND ENGINE COOLING:ENGINE:ENGINE CONTROL MODULE (ECU/ECM). CRACKED REAR DIFFERENTIAL: Be aware that some new AWD vehicles have been found with cracked rear differential cases, as shown below.

Some customers may complain about a high frequency noise (like a mosquito sound) while the active driving display is in the flip-up position. The noise may be coming from the capacitor inside the active driving display which vibrates according to the display control frequency. The circuit board resonates with it resulting in an audible noise. To eliminate this concern, the active driving display has been modified to use a higher frequency for the display control.

09-008-20-36752020-01-30. Service bulletin. STRUCTURE:BODY; EQUIPMENT. Some vehicles may experience stains appearing on the hood, roof and/or trunk of the vehicle. This concern is most likely to be found in a cold weather areas just after the RAPGARD is removed at PDI. This may be caused by moisture which has been trapped and condensed between the paint and the RAPGARD. These types of stains can be removed with a heat gun or an infrared drier. If you encounter this concern during PDI, use a heat gun or an infrared drier to apply heat to the affected area to remove the stain(s).
