If there is a problem with the sensors they should fix it. I'm not at tech, so I'm at the mercy of the dealer. Too be clear, I haven't paid the $22.50 because I dispute the charge every time. It's a **** poor way to deal, try to stick the customer and if he makes enough noise, then waive the charge, instead of simply not charging. I have to argue every time I go in. It's a terrible way to do business.
