NHTSA's summary

Some customers may complain about one or more warning lights ON when they start the vehicle during hot weather. The following DTCs are stored in memory: U3000:98 - Forward sensing camera (FSC) stops functioning due to temporary high temperature. U3000:04 - Forward sensing camera (FSC) internal malfunction. The combination of warning lights mentioned by the customer may include: Instrument Cluster Multi-Information Display (if equipped) warning messages may include: Forward Smart City Brake Support Malfunction, Smart Brake System Malfunction, Front Camera Sensor System Malfunction, MAZDA CONNECT center display warning messages may include: High Beam Control [HBC] / Lane-keep Assist System [LAS] Malfunction. Have the vehicle checked by a dealer if this indicator stays on. Smart City Brake Support [SCBS] Malfunction. Have the vehicle checked by a dealer immediately. Note: The center display Warning Messages are only displayed when the customer selects Applications>Vehicle Status Monitor>Warning Guidance>Warnings. This condition may be caused by FSC control logic that is too sensitive. When the FSC detects DTC U3000:98 during high temperature, it stops the internal communication and stores DTC U3000:04. DTC U3000:04 will not clear and SCBS/SBS, LAS/LDWS, and/or HBC functions will not resume until the ignition switch has been turned OFF even if the temperature of the FSC cools.

01-018-16	2021-01-25. Service bulletin. Unusual engine noise after a cold engine start. Some customers may complain about an unusual noise coming from the engine compartment for about 20 seconds after a cold engine start. This noise is a normal engine operation for improved exhaust gas emissions. The noise does not indicate a malfunction.
09-031-20-3736	2020-10-03. Service bulletin. Some vehicles may exhibit a distorted image or no image from the rear mount camera when shifted into reverse. Due to friction, the coating of camera socket terminals may wear out, creating high electrical resistance. NOTE: The icons and the messages are displayed normally.
SA-038-20	2020-04-06. Service bulletin. Some customers may complain about a rear view monitor display that is: • Blank (or may have backup camera warning message) • Distorted • Blurry • Fuzzy • Split screen (see attached video) • Grainy. The icons and text are normally displayed.
15-004-19-3639	2019-10-04. Service bulletin. Some customer's may complain that In heavy rain, the front parking sensor system detects objects despite nothing being in front of the vehicle, and no related DTCs are stored. This may be caused by the ultrasonics diffusing inside when the front parking sensors get wet. As a result, the parking assist unit mistakenly detects objects near the front of the vehicle. To correct this issue, the detecting logic in close range has been improved.
09-033-19-3590	2019-08-21. Service bulletin. Some vehicles may exhibit the rear parking sensor beeping without any obstacles behind it when the shift lever is shifted into Reverse. This concern only occurs when the rear USB power outlet (1) is broken. This is caused by noise from USB interference with the harness of the rear parking sensor (when the USB power outlet is broken).To correct this issue, the configuration of the USB power outlet has been changed to improve durability.
09-032-19-3579	2019-08-21. Service bulletin. Some customers may experience improper operation of the rear parking system with beep sounds coming from the rear parking sensor when there are no obstacles behind the vehicle. This occurs when the blower fan is on (at any fan speed) and the transmission is in "R" position. The concern is caused by electrical noise from the blower fan controller circuit affecting the rear parking sensor circuit. To eliminate this concern, the harness to the rear parking sensor has been twisted to improve its tolerance to electrical noise.
