+1, very anowing! Nissan, please get proper info to owners for this issue. I've been trying to fix that for 2 years now. I will not pay for that. Reading your own safety stuff in the owner's book: "it is the driver responsibility to ensure proper inflation of the tires!" We paid for those device to assume our responsibility, do your part and get them at work finally,...not for 6 months at a time plus fees. This is not a cell phone or other electronic gimmics, we are not supposed to sign a bi-annual contract to make it work.
