We are having the same passenger wiper jamming problem with our 2016 Miramar.
There is a lot of slop in the assembly. At first the passenger wiper swings across normally: It ends right in front of my view of the road, but then swings further across until the passenger wiper over-extends and jams the drivers wiper.
The back and forth rod assembly has a lot of play and throws the wiper crank over the top and pulls the wiper down past the windshield.
FYI we’ve had it into dealers four times, including the two recalls, with no fix in sight. Have applied Rain-X to avoid using wipers as much as possible.
Taking it in again to try and get this resolved. For normal rain it’s more a surprise irritation, but in a heavy downpour it can be downright treacherous.
