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.
Loose brake calipers can reduce braking performance or interfere with wheel rotation, affecting vehicle handling. Either of these scenarios can increase the risk of a crash.
Mazda will notify owners, and dealers will inspect the front brake caliper bolts, tightening them as necessary. If bolts are missing, the affected brake caliper will be replaced. 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.

Representative owner complaints: fuel/propulsion system
2 reports, newest first. Show all
Fuel/propulsion system, Jul 2, 2026
Low pressure fuel pump failure with 75,575 miles on odometer. Fuel pump completely seized. Car was parked at a retail location and would not start. Upon troubleshooting, mechanic was able to determine the low pressure pump was not delivering fuel. Pump was replaced. Faulty fuel pumps could lead to hazardous conditions as they are mounted within the fuel tank. I feel this is too early in the vehicles life for this component to have completely failed.
