Currently, the answer is none.

Ford produced the Freestyle for the 2005 to 2007 model years, more than enough time for the name-brand rental car companies to have swapped those model years from their fleets.

The original Ford Freestyle had problems with power loss – that is, the engine would race, with no power going to the drive train, causing the car to come to a complete stop. This symptom became known as the throttle body problem.

One person reported the throttle body problem happened three times within 15 minutes. Each time, he had to pull over to the side of the road, turn off the engine and restart it to reset a computer.

After being told many times by the dealership that a throttle body problem didn’t exist, he was finally told it was a bad Megatronix unit that would cost $1,500 to replace. When that didn’t fix it, he was told his car would require a new $4,500 transmission.

Ford reintroduced the Freestyle FX for the 2010 model year, probably too soon for Avis, Budget, Hertz, Enterprise, National Car Rental and Thrifty to include them in their fleets.

MotorTrend says the changes to the Freestyle for the 2010 model year are minimal, including front-seat side airbags and standard side-curtain airbags for all three rows starting midyear, as well as new option packages: Convenience, Interior Power, Limited Convenience, and Safety and Security.

One would hope Ford also fixed the throttle body problem.

If you’re thinking of buying a Ford Freestyle FX, try renting one from your local Ford dealership. Not all dealerships rent all Ford models, but it’s worth a try.

It’s also worth remembering that requesting a specific model almost certainly guarantees that you won’t be getting the lowest priced rental car.
