Mazda is recalling 19,000 2014 MAZDA6 sedans because the fuel tank can be filled beyond its rated capacity. An overfilled tank can send gasoline into the charcoal canister and out the external vent, which raises the risk of a fire; the Mazda dealer repair will be free once available.

What's wrong?
The fuel tank on the 2014 Mazda MAZDA6 stores gasoline and keeps it contained while the fuel system feeds the engine. It is designed around a rated capacity, with space left for fuel vapor and normal expansion instead of filling every part of the tank area with liquid fuel.
On affected MAZDA6 vehicles, the tank can be filled beyond that rated capacity. The problem is not that the engine needs extra fuel; it is that the tank accepts more gasoline than Mazda designed it to hold, which defeats the intended fill limit.
There is no warning sign before failure. The issue is tied to how much fuel the tank accepts during refueling, not a warning light, sound, smell, or change in how the car drives.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether this recall applies to your specific sedan.
What's the safety risk?
If the fuel tank is overfilled, gasoline can enter the charcoal canister. Gas in that emissions component can leak from the external vent and raise the risk of a fire. Do not top off the tank, and schedule the recall repair soon. Repair will be free at any franchised Mazda dealer once available.
What should I do?
- Check your VIN to confirm your 2014 Mazda MAZDA6 is included in this recall.
- Contact a franchised Mazda dealer and ask whether the free fuel-tank shut-off-valve and charcoal-canister repair is open for your VIN.
- Reference recall number 14V170 when you call. Mazda also lists recall number 7414D.
- Bring the owner notice if Mazda mailed one after the recall began on May 19, 2014.
- Avoid overfilling the fuel tank until the repair is complete. Stop fueling when the pump first clicks off.
What happens at the repair
At the dealer, a Mazda technician inspects the fuel tank shut off valve and adds an adapter so the tank cannot be filled beyond its rated capacity. The technician also checks the charcoal canister for gasoline and replaces the canister if gasoline is found. The final dealer repair will be free once available for your VIN, with parts and labor covered under the recall.
