What is wrong
Mazda North American Operations (Mazda) is recalling certain 2019-2020 Mazda3 vehicles. The Smart Brake System (SBS) can falsely detect an obstacle while driving, activating the automatic emergency braking system and suddenly stopping the vehicle.
What can happen
Stopping the vehicle unexpectedly increases the risk of a crash.
The remedy
Mazda will notify owners, and dealers will update the SBS software. In addition, vehicles with certain production dates will receive an instrument cluster software update or replacement and a replacement owner's manual. These repairs will be performed free of charge. The recall began February 14, 2020. Owners may contact Mazda customer service at 1-800-222-5500, Option 4. Mazda's number for this recall is 4219L.
Notes
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

SSPC5 - SPECIAL SERVICE PROGRAM - 2019-2021 MAZDA3 AND 2020-2021 CX-30 - CONTROL UNITS REPROGRAMMING Concern 1: Mazda3 and CX-30 – Battery concern On the subject vehicles, the CCU (climate control unit) and BCM (body control module) may not go into sleep mode even after the ignition is switched OFF or may take time to go into sleep mode. An electric current may continue to flow, allowing the battery to discharge and run out if the vehicle is left unused for a certain time. Causal factor: Inappropriate control program of CCU and BCM. Update to BCM will also update the IC, DOOR_ESU_D, DOOR_ESU_P, ESU modules. Concern 2: Mazda3 and CX-30 - MRCC concern: On the subject vehicles, the responsiveness when driving following a preceding car using the MRCC (Mazda Radar Cruise Control) system is designed to high response. Some drivers may feel the acceleration and deceleration jerk when using MRCC somewhat uncomfortable. The product update has been incorporated into mass-production Mazda3 and CX-30 vehicles, and acceleration and deceleration has been made more natural by changing controls to be closer to human expectation. The similar update will be made on the subject vehicles produced prior to the product update under this SSP. * MRCC: Mazda Radar Cruise Control (MRCC) uses a millimeter wave radar to judge the relative speed and distance to the car ahead and automatically controls vehicle speed. Working within a set speed range, MRCC automatically adjusts and maintains a safe following distance from the car in front. Concern 3: CX-30 - Theft-Deterrent System concern On the subject vehicles, the theft-deterrent system may not recognize correctly the open/close state of power liftgate, which may allow the theft-deterrent system to activate wrongly when the liftgate is opened by pressing the power liftgate switch. Causal factor: Inappropriate control program of BCM and LFU. Update to BCM will also update the IC, DOOR_ESU_D, DOOR_ESU_P, ESU modules. |
