Elevated severity

What the defect is

Mazda North American Operations (Mazda) is recalling certain 2021 Mazda3 and CX-30 vehicles. Air may suddenly leak from the tire air valve.

Why it matters

A sudden air leak from the tire air valve may cause a loss of vehicle control while driving, increasing the risk of a crash.

The remedy

Mazda will notify owners, and dealers will replace all four tire air valves with new parts, free of charge. The recall began April 6, 2021. Owners may contact Mazda customer service at 1-800-222-5500 Option 4. Mazda's number for this recall is 4721B.

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.
