You are correct. How many companies are going to want a fleet of unreliable vehicles though?
Ford trucks are great. All companies have exceptions.
Although I have never heard of a ford being bought back for frame rust on a car less than 5 years old.
That is becauses they won't acknowledge the issue. My buddies 01 Ranger looks worse than any tacoma frame I have seen and they won't do anything about it. From what he states, there are many people with the same issue. I have yet to confirm this though.
