There are issues where the dash display goes blank and the headlights do not operate properly. The headlights will not switch from dim to bright automatically or manually. At times one or more lights will not even illuminate. It is not a constant problem but intermittent instead. We are not comfortable driving the vehicle after dark because it may happen at any time.

When the turn signal bar is in the neutral position, the right turn signal stays on. When the turn signal bar is in the left position, the right turn signal turns off, but the left turn signal stays off. This makes it impossible to signal left, and often causes the right turn signal to come on, which can be misleading to other drivers.

Went to start the vehicle with the key fob and the vehicle would not start. Had it towed to ram dealership and was told that the RF hub module needed to be replaced due to being damaged from water at leaked in from the rear window. Upon researching online forums, this seems to be an ongoing problem for this making model because of where the module is located. If there is not already in the works, there should be because this will continue to happen, especially where it rains a lot.
