So i live in a snowy area and theres a lot of salt. my dealership put a metal valve stem cap on for some stupid reason and it corroded on the stem and broke the valve. i have the valves with the sensors to let me know if my tire pressure is low... i went to get it replaced...$150 for the valve...20 for tire mount and balance...and $60 for activation?! Is toyota frickin serious with this?!?!!?...i went to sears and had them throw a regular one on for 20 bucks.
