Consumer Description

The electronic tailgate switch is malfunctioning and opening on own. We brought in and paid 2 times to have repaired and now the third time has happened. It’s appears this model is recalled in Canada but not US. Why is that when it’s the same parts used and the HD models have also been recalled. Why is our truck not recalled for this?
