Owner report 11419118 · 2021-05-31 (May 31, 2021)
I was driving 35MPH on a side street in “sport” mode. Car system beeped, car auto stopped, red circle with explanation mark and the word Break appeared on my center console. My drive shift popped out of Drive. No object was in front of my car, nothing ran out in front of it. Fortunately, there weren’t any other cars behind me or an accident would have followed.

Owner report 11430207 · 2021-08-23 (August 23, 2021)
The Mazda Radar Cruise Control (MRCC) system performs poorly (it does not hold a set speed well up and down hill; compared to our 2006 Mazda3), but the safety concern is the forceful, sudden, and not-always-predictable braking the vehicle does even if there is not another vehicle in front of us. It brakes, sometimes, for a vehicle in the right lane (we, in the left), and continues to brake unless we override the system. No problem--except if there may be someone following too closely, it could cause a collision. It seems to be related to the MR…

Reported: 2019-12-19 (December 19, 2019)

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.

Reported: 2020-06-12 (June 12, 2020)
Mazda North American Operations (Mazda) is recalling certain 2020 CX-30 and Mazda3 vehicles. The front brake caliper mounting bolts may not have been tightened properly during assembly, possibly allowing the calipers to loosen.

Repairs will be performed free of charge. The recall began July 24, 2020. Owners may contact Mazda customer service at 1-800-222-5500, Option 4. Mazda's number for this recall is 4420F.
