Time Point

Thousand Per Month Value

Equipped cars with new shifting transmission (bad concept)

First year 3,469 reported problems

Consistent software updates or replacing transmission

Number of Ford Focus recalled

Vehicles were equipped with a “dry” method clutch instead of a “wet” one. Caused vehicles to have problems downshifting. When accelerating, vehicle would hesitate and keep it from reaching speeds of a normal vehicle. There have been consistent software updates and even replacing the transmission 2-4 times within a 3-4 year of ownership. This is clearly a Lean Six Sigma Waste. It would fall under defects.

Summary and Recommendations

Remove defected vehicles from roadways

Offer incentives to help remove defected vehicles

Should settle any pending lawsuits

Because the Focus has taken such a devasting lost over the years. It is best for Ford to stop production on this vehicle. If they continue to produce this vehicle, it could put someone in the biggest danger, death. For the vehicles that are currently being used, incentives should be given to return the vehicle. These incentives would be use to purchased another vehicle in Ford’s lineup. This should settle any lawsuits and help with Ford’s market value and image.
