Across the board, Fusion Hybrid owners are complaining about their fuel efficiency.

A proposed class-action lawsuit takes aim at Ford saying the Fusion Hybrid gets nowhere near its advertised MPGs. To make matters worse, the lawsuit says Ford issued a software update that deceptively changed the MPG numbers on the instrument panel, without actually making the car more fuel efficient.

What’s that called again? Starts with an “L” … it’s something automakers think they can get away with … oh, right: lying.

It’s unclear at this time what model years the lawsuit focuses on. What is clear, however, is that some owners are more than a little ticked off about this double-dose of deception. You should be too.
