What's the latest on the best source for the TPMS Sensors?

I have bought them before on Ebay, only to have them die after a year or so.

I suspect they were old stock where the batteries where already old when I got them.

These look good and they are AC Delco:
TPMS

Thanks

For your newer SS ? I had looked them up several times/places and was scared about getting some old stock.
I do recall that the stock SS wheels required the metal stemmed TPM’s.

 

The SS rims OEM sensor part number is 20925924

I can’t confirm if the rubber valves tens fit those rims , but at the price I would try. Maybe swap the sensors themselves

 

The sensor doesn't care which type of stem. Only tire stores think there is a difference, they try to sell expensive stems. My local store tried to convince me I should pay $15 per wheel for a stem kit that consisted of a core, a chromed plastic stem cover and a chromed cap on top of the "special" $10 rubber stem. They said it was "required" for the warranty. I went to AutoZone and got 4 "special" rubber stems for $10, they are "special" because they have a (2 cent) brass threaded bit for the sensor to screw into.

NAPA claimed that all HHRs use the metal stem with the sensor all together in one box. Can't buy one without the other.

Any wheel can use metal stems, most alloy wheels need metal, some can accept rubber.

One thing that might require metal stems is for a RF antenna but I think that is bogus.

 

Actually, these TPMS Sensors are for my daughters 2011 HHR 1LT with 16" aluminum wheels.

Then those are correct. Two of mine just failed yesterday

 

Supposedly, the metal stems are 'required' on cars capable of going over 150mph, I've been told that by a few people NOT in the business of selling expensive TPMS stems.

When I put the AR Torq Thrusts on my 08 panel, I went with all new TPMS from Discount tire. Sometimes, and only at speeds above 70mph, I will lose signal from the right rear sensor, and occasionally the left rear. I've rotated the tires, but it's still the same position failing.
My guess is that the aftermarket sensors don't have as strong of a signal and the receiver will not get the signal reliably at high speed. I think the receiver is up near the front by the mirror, so this makes sense.
I have an Autel TPMS tester, and have tested the signal when the TPMS light is on and no data is displayed on the dash for the right rear wheel. Sensor tests fine, and because of this, Discount tire won't warranty it.

Right now, I'm glad the 07 panel I just bought doesn't have this nonsense. I'm not the type of person who likes driving around with warning lights on, even if I know WHY they are on. To me, that just means something else could fail and not give a warning, because the warning light is already on.

 

The ‘08 model years did have issues with the RCDLR location and programming.

 

2007 the RCDLR is under the rear quarter trim behind the driver. In 2008 TPMS became mandatory, the RCDLR was moved to under the headliner by the mirror. The people responsible for writing the 2008 program forgot to account for loss of power to the memory, so a 2008 that experiences a dead battery will need to have a reflash with updated firmware.
When I took my 2008 into the dealer to reflash the RCDLR the tech tore the interior apart and declared it was not equipped with remote door locks, while using the fob to lock it. Turns out the 2008 shop manual didn't get updated, it still says the RCDLR is under the quarter trim.
After I convinced him that it did have one he had to call Techline to tell him how to do it. This was in early 2009 when they should have had a clue.

 

My dealer experiences of late have been less that stellar, so much so that I'm reluctant to bring my Yukon in for the airbag recall. I'm sure that something will be horribly broken afterwards.
