2021 Mazda Mazda3: Recalls and Reported Problems
Every NHTSA safety recall recorded for this model year, what owners report most often, and how to check whether one specific vehicle still has open work.
Two identical Mazda3s can differ entirely: one may have had every recall repaired, the other none.
NHTSA lists 1 safety recall for the 2021 Mazda Mazda3, alongside 49 owner complaints filed with the agency, most often about engine. Recall repairs are performed free of charge by a franchised dealer, with no expiry on safety recalls. A recall applies to a production range, so check the specific VIN — a previous owner may already have had the work done.

Recall campaigns for the 2021 Mazda Mazda3
Each campaign below is an official NHTSA record. The remedy is performed free of charge by a franchised dealer, and safety recalls never expire — but a campaign covers a production range, so only a VIN lookup confirms whether a particular vehicle is included and whether the work is still outstanding.
| Campaign | Component | Issue |
|---|---|---|
| 21V101000 | TIRES:VALVE | Mazda North American Operations (Mazda) is recalling certain 2021 Mazda3 and CX-30 vehicles. Air may suddenly leak from the tire air valve. |
How to check one specific Mazda3
- Copy the 17-character VIN from the windshield or driver-door label — not from the listing.
- Run it through NHTSA’s free recall lookup to see open campaigns for that exact vehicle.
- Ask the seller for repair documentation on any campaign that shows as completed.
- Check title, odometer, and total-loss history separately; recalls say nothing about a vehicle’s past.
- Book an independent pre-purchase inspection focused on the systems owners report most.
What this data cannot tell you
- Whether a specific vehicle is included in a campaign, or whether its recall work was completed — only a VIN lookup answers that.
- Whether a complaint is accurate. NHTSA publishes owner reports without verifying them.
- How reliable the model is overall: complaint volume tracks how many vehicles were sold as much as how they hold up.
- Anything about title brands, accident history, odometer records, or liens on an individual vehicle.
