What's wrong?
The CNG storage tank on 2011-2012 Mv-1 MV-1 vehicles holds compressed natural gas for the engine. Because the fuel is stored under pressure, the tank uses a pressure relief plug as a safety part that gives excess pressure a controlled path out of the tank when the system needs relief. That plug has to be assembled correctly to do its job.
For recall 12V468, the problem is the pressure relief plug on the CNG storage tank was assembled incorrectly. An incorrectly assembled plug does not match the intended tank configuration, so the tank's pressure relief path does not work as designed. The issue is in the fuel storage tank assembly, not a routine engine tune-up item.
There is no warning sign before failure. Owners should not expect a dashboard light, fuel smell, or change in how the engine runs to confirm this defect.
Who's affected?
Only the MV-1 model is included here; both listed model years carry the same fuel-system component.
| 2012 Mv-1 MV-1 | fuel system |
|---|---|
| 2011 Mv-1 MV-1 | fuel system |
| Units affected | 435 |
The year and model narrow the list, but the VIN decides. Check your VIN to confirm whether your specific vehicle is included.
What's the safety risk?
An incorrectly assembled plug can release CNG. If that gas reaches an ignition source, it can ignite and result in a vehicle fire. Drive cautiously, avoid ignition sources near the fuel system, and contact the dealer to confirm repair timing. Repair will be free at any franchised Mv-1 dealer once available.
What should I do?
- Check your VIN to confirm your 2011-2012 Mv-1 MV-1 is included in this recall.
- Contact a franchised Mv-1 dealer to confirm repair availability for your VIN.
- Reference recall number 12V468 when you call, and ask about the free secondary pressure relief device that prevents CNG from leaking from the storage tank.
- Bring the recall notice if you have it.
- Keep ignition sources away from the CNG tank area if you smell gas or suspect a leak, and ask the dealer whether the vehicle needs towing.
What happens at the repair
The planned dealer fix is to install a secondary pressure relief device on each affected CNG vehicle so the pressure relief plug area does not leak. Parts and labor are covered by the recall once the repair is available. The safety recall began on November 13, 2012, but the current remedy status supplied for this page is not marked available. Confirm your VIN before arranging service, then ask the Mv-1 dealer how they will complete the no-cost pressure relief device installation.
