Tire pressure monitors going bad?

https://www.stevejenkins.com/blog/2014/11/tpms-warning-light-replace-your-tpms-sensors-for-cheap/

So I looked up the TPMS sensor OEM part number for my 2007 GMC and found (without any surprise) that the same sensor is used on nearly all GM’s trucks and SUVs of that era: Cadillac Escalade, GMC Yukon, Chevy Suburban and Tahoe, etc. The OEM sensor (made by AC Delco) had an MSRP of $72.44. Local auto parts stores sold decent quality non-OEM replacements that were compatible with my vehicle for between $52 – $62 each. Alright. Now we’re getting warmer.

But to my surprise, I found these AC Delco OEM TPMS sensors for my GMC Yukon — the exact same ones the dealer would have installed — on Amazon.com for $27.29 ea (including free shipping). So for $109.16, I had all four sensors in my hands within 2 days. I was concerned that maybe they’d be used, or somehow not as advertised. But they arrived brand new, in two days, in the original packaging:

1. RockAuto.com is another great resource.

3. RockAuto.com is very good

I've also used ebay. I needed a new front differential and looked around at a few yards who wanted $350-450 used. I found one on ebay for $200.

I needed a new electric cooling fan clutch. New from the parts houses: $175. New on ebay: $68 (With free shipping) with paypal discount $50.

5. My problem with ordering parts

is that I know just enough to get in trouble.

6. While learning is sometimes a trial and error exercise...

...it isn't always painless. I feel your pain.

2. The TPMs on my Hummer

Wig out in freezing weather. I get a tpm error on the DIC.
IMO... they may be mandatory but I can regularly check the air in my tires all by my female self and I am positive I am smarter than those monitors.
Lol

4. re: "...I am positive I am smarter than those monitors."

I am also.

I long for the days when my car had fewer computers than I have in my house.

7. that is the advantage of old cars

my 2001 kia seems rather simple compared to newer models

friend just bought a new ford and we still do not know how to get the radio to am so we can listen to the ball game

that and no car payments are good too

8. My car is an '03

For me an "old" car is one that can still use leaded gas.
