What's wrong?
The check valve in the 1990-1992 Daihatsu Rocky fuel vapor evaporative emission control system is a small one-way valve. Its job is to help manage gasoline vapors from the fuel tank so the vapor control system sends them in the intended direction instead of letting pressure move the wrong way. That keeps the fuel vapor system working as designed during normal driving and parking.
On affected Rocky SUVs, the check valve does not have enough durability for long-term vehicle use under certain environmental or operating conditions. Over time, the valve body can crack. Once cracked, it no longer controls fuel vapor flow the way it should, and the evaporative emission control system loses part of the barrier it depends on.
There is no warning sign before failure. An owner will not necessarily hear, feel, or see the check valve crack before the system stops working correctly.

What's the safety risk?
Fuel evaporative gas vapor leaking into the cabin creates a fire risk. If your VIN is included, schedule the recall repair soon and keep flames or sparks away from the vehicle until the check valve is replaced. Repair will be free at any franchised Daihatsu dealer once available.

What happens at the repair

Daihatsu says this service is free and began on March 31, 2010. If your VIN is included, ask the dealer to confirm the recall campaign and install the replacement check valve before returning the vehicle to regular use.
