There is no federal law requiring rental car companies to warn consumers if the vehicle they are renting is under a safety recall.

So... whip out your smart phone or tablet before renting a car, and see if it's been marked for recalls, then check with the rental car agency to see if they state that they have sent their cars, especially the one you are renting, to the dealership for recall work to be completed
