Ford said it was not aware of any accidents or injuries related to the problem.
A frozen latch found in these vehicles may cause doors to not open or close correctly.
The automaker said it will notify customers by letter the week of November 13 to let them know if their trucks are part of the recall.
The f-150 pickup has been the bestselling vehicle in the country for decades. The bulletin told dealers to install a rain shield to address the problem. "When the data indicates a safety recall is needed, we move quickly", she said. Affected trucks are 1.1 million in the United States, more than 222,000 in Canada and 21,000 trucks in Mexico.
Even if customers are able to open and close the door, that latch may not fully engage, meaning the door could fling open while driving, Ford warned.

A Coast Guard helicopter, along with Coast Guard vessels and boats from local agencies, continued looking for the missing worker. The Coast Guard will be conducting a water quality evaluation as well as the Lake Pontchartrain Basin Foundation.
The recall of the trucks, Ford's best-selling and most profitable model line, is so big that the company made a filing with the Securities and Exchange Commission informing investors that it will have an expense of $267 million, which will be reflected the company's fourth quarter 2017 financial results.
Despite the hit, Ford said that it still expected to earn between $1.65 and $1.85 per share for the full year.
In September 2016, Ford said it was taking a $640 million charge for its expanded side-door latch recalls.
The recall is for a faulty driver's side door that may allow the door to open unexpectedly while the vehicle is moving. It shares were flat at $12.20.
