I have replaced all four TPMS sensors originally they worked for a while. I don’t drive the car every day but I have the tires checked and they’re all good, holding pressure Is it possible that all 4 my sensors are defective?

 

Where did you get them from? I bought brand new ACDelco sensors for my Corvette from a seller on ebay and they didn't last long at all. The seller got frustrated with me after 3 failed within a few months, like I had done something wrong, and wanted all of the sensors back for a refund. Gladly. I then bought a set of Schraders (OEM) from tpms.com and they've been perfect. So, yes, it's possible they're all bad.

 

Yes I will not be buying them from eBay to save a couple bucks anymore I bought them directly from the manufacture I all for work 100% thank you.

 

A lot of "official" parts on eBay (ACDelco/Toyota/Mishimoto/etc) are really just elaborate Chinese fakes.

I've seen it with a handful of different brands, as well - been burned on one specifically a handful of years ago. You have to pay attention to who the seller is - even then, I tend to avoid eBay for parts.

Someone did a YouTube video recently of this with Toyota parts. Boxes looked correct and the parts looked right to the unsuspecting eye. He would have never known had there not been a tiny slip of paper inside one of the boxes that said "Made in China".
