I took my car through a hand car wash but it has a metal guide track. I didn't remove my FOBO sensors and the track broke off both valve stems and of course lost all pressure. I got the car to a tire shop, but I'm wondering if they can replace just the valve stem or if the entire TPMS unit now needs replacement. My VIN is 15xxx so it's the early version. I've taken the car to this wash before without any problems, just this time I guess I was too close to the left track rail. Lesson learned.
