What's wrong?
The fuel tank assembly on the recalled 2012 Acura Mdx and Pilot vehicles stores gasoline and manages vapor movement from the tank. Inside that assembly, the vent shut float valve case holds a small float valve. During normal operation, that valve helps control the tank vent path so air and vapor move where the fuel system expects them to go.
In recall 12V063, the valve case in the fuel tank assembly does not meet Honda's design specifications. That means the case was built outside the intended design limits, so the valve housing is not the exact part the tank design calls for. The concern is inside the fuel tank assembly, not a trim piece or dashboard part an owner can inspect from outside the vehicle.
There is no warning sign before failure. An owner should not expect a warning light, sound, smell, or change in drivability to confirm whether this defect is present.
Who's affected?
Covers the Mdx and Pilot in the same model year, with both tied to the fuel tank assembly.

A matching year and model does not confirm inclusion. Check your VIN to confirm whether your specific SUV is included.
What's the safety risk?
A fuel leak from the tank raises the risk of fire. Schedule the recall inspection soon, and keep fuel odor or visible leakage away from heat, sparks, and enclosed storage. Repair will be free at any franchised Acura dealer once available.
What should I do?
- Check your VIN to confirm your 2012 Acura Mdx or Pilot is included in this recall.
- Watch for Acura's recall notice, mailed on March 13, 2012, if you have not received one.
- Contact a franchised Acura dealer and ask about the free fuel-tank inspection for recall number 12V063.
- Schedule the VSF valve and fuel-tank assembly inspection that checks for the fuel leak risk, with tank replacement if needed.
- Bring the recall notice if you have it, and tell the dealer the fuel tank assembly is the recalled component.
What happens at the repair
At the dealer, an Acura technician inspects the vent shut float assembly date in the fuel tank. If the assembly falls within the recalled build range, the technician replaces the fuel tank assembly. The dealer repair is free once available, with parts and labor covered by the recall. This inspection matters because the valve case is inside the tank assembly, so the service desk confirms the affected part before replacement.
