NHTSA Complaint #11435636 — 2010 MAZDA MAZDA3

As the original owner, I have now experienced (4) faulty/broken/corroded valve stem as part (attached to the TPMS-Tire Pressure Monitor System). This happened over the course of 12 years. I do believe all of them were OEM parts. All of them broke when attempting to air up the tire. It is a safety issue because once broke, you can no longer put air into the tire. The first occurrence was while still under warranty and i had to argue with the Mazda dealer to replace it . The dealership gave me some sort of unofficial receipt which I actually kept, found, and attached to this complaint form. During my second set of tires, Sams Club graciously replaced 2 more as part of their tire warranty package (I dont think they documented this on their receipts). Now, what i believe to be the final OEM stem left has broke. Unfortunately, I have a third set of tires through Costco and they wont replace without a fee. This should be a safety recall absolutely no doubt in my experience!
