There will never be a recall on any engine that has 140K miles on it. Never
The absolute best you may get is a class-action lawsuit, in which you'll get a percentage of the repair back. That's it.
Why? First, the water pump is considered a "wear and tear" part. In other words, they degrade over time, and they fail. They may not fail as frequently as in years past, but I've owned more than one vehicle that needed the water pump replaced.
Also, the NHTSA will NOT issue a safety recall over this, because it's simply not a safety issue. If it fails, the engine may die, but the car will still be driveable, and will allow you to stop and exit the vehicle safely. Now, a failing steering column, suspension components, brakes, airbags, etc. that may fail and possibly lead to severe injuries or death? That's what warrants a safety recall.
