Is there any logical reason why a national chain like Car-X wouldn't carry TPMS Rebuild Kits? Of course, I realize that they want to sell more brand-new TPMS sensors at $75 a piece. I have a wheel with a slight leak. The local Car-X shop blames the TPMS sensor, and wants to replace it for $75. The sensor works just fine, as it has been signaling that there has been a slow leak of air for the past couple of months. I asked them why they don't carry the $5 rebuild kits. I was told that "we just don't". Really?
