Gotdamn... Infiniti must sync across the country since mine just went out too. I searched and searched for a solution. Thankfully I have an extended warranty, dropped it off at Infiniti and found out all four are bad. Glad its being covered. I told them they were full of shit and they stuck to their guns saying Nissan actuators must suck cuz they get all kinds of cars in all the time that have bad actuators, and all four going out together is no surprise.
