Turns out, that the check valve in the fuel vapor evaporative emissions control system of 1990-1992 Daihatsu Rockys might crack, causing fumes to fill the cabin. Gasoline fumes inside your Rocky's cabin are bad (think fire, explosions), especially if you smoke. Of course, if you own a convertible Rocky, this won't be too much of an issue. Still, might as well take advantage of this NHTSA recall at your local Daihatsu dealer. Wherever that might be.
Also, in case you've been worried sick about it, there are no recalls for the Toyota Starlet. Phew!
