Elevated severity
This campaign addresses a defect NHTSA classifies as carrying elevated crash or injury risk.
What the defect is
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.
Why it matters
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.
The remedy
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.
What this page does not include
NHTSA's public recall feed does not supply an affected-population count, the manufacturer's own campaign number, owner-notification dates or a defect chronology for this campaign. Rather than estimate them, we omit them. Confirm whether a specific vehicle is affected — and whether the repair has already been done — using its VIN.
