“We have been to the dealer 3 separate times for our ac not properly cooling. And also no air flow through out the van. As well as the rear driver passenger door button doesnt open all the time.”
NHTSA complaint #11769908, filed 2026-10“The center console between the front seats has a design defect. When small objects such as a credit card, key fob, or coin are left on the flat surface of the console, they can slip through a gap into the internal storage compartment.
