So today my low tire light came on.. again.. for the third time..

The last 2 times this has happened it was because there was a leak in the tpms sensor, and they've had to replace the entire assembly which is right around $150. If this is another tpms sensor I'm gonna be ripped. I have owned this car less than a year and have already put in $600 in repairs none of which were my fault. Starting to think I should've kept my old beater instead of buying a relatively new car.. Would've cost way less even though it needed a new tran. That sorta turned into a rant about how much i am disliking my V right now. Anyways, I got the tpms components replaced when i switched the summer and winter tires and then replaced again when i switched back in the spring. I do live in an area with bumpy roads, but nothing that I would think could cause this much damage to my tpms sensors? Has anybody else had 3 sensors go on their car? Im getting this checked tomorrow, and im hoping I just have a nail in their somewhere

And before anyone asks, yes the bumper to bumper warranty is expired, so its not covered. the first one was, but the last one I had to pay for myself. Last time the dealership charged me $45 to reset the warning light..
