Ford has issued a recall of about 221,000 F-150 pickup trucks in Canada, saying the vehicles are at risk of a potential transmission downshift.

The downshift “can cause the vehicle to slow down suddenly and without warning. This can also cause the rear tires to skid or lock up, increasing the risk of a crash,” the US National Highway Traffic Safety Administration said in a statement.

The automaker said select 2011-2013 model year trucks with six-speed automatic transmission could have the defect. Ford also announced it is aware of five accidents related to the issue – including one that led to whiplash injuries.

The Canadian recall is just a portion of the 1.48 million trucks in North America Ford is pulling out for the downshift issue, Global News reported.

Vehicles returned to dealerships will have their powertrain control software updated to resolve the issue.

On top of the F-150 recall, Ford is also recalling 28,200 2017-19 Lincoln Continental vehicles in North America for faulty door latches, as well as 4,200 2019 model Ford Mustang, Lincoln Nautilus and Lincoln Navigator vehicles for instrument panel cluster assemblies that appear blank when the car starts.
