I can tell you that production has been shut down at least 3 times now due to a particular suspension component failing. Assembled vehicles have had to be disassembled due to this faulty component. The component has been redesigned in an attempt to remedy the issue and controls are in place to ensure faulty parts never make it to vehicles, however the failure is one that can come up at any given time, at any point through it's life cycle. Parts that have been known to be good have failed less than 24h later.
I can also tell you that another suspension/drivetrain component, which was within Ford's own spec, has also been found to be failing and is currently (as of December 7, 2006 - the day they supposedly started shipping to dealerships) being disassembled from vehicles to be reworked and reassembled. I am not clear on how the shipped vehicles will be handled, however I do not think any of them will leave a dealership until this part has been reworked.
Now, off I go to disappear and attempt to keep my identity to myself - Ford themselves don't neccesarily know the aforementioned part still has failures...and I dont think they want anyone to know about the new issue...Thankfully, I don't work for Ford ;-)
