Even the dealer can't get rid of my TPM messages. Yesterday the H3 was in for service and they themselves set the tire pressure, re-calibrated the system, poked, prodded, etc. They are dumbfounded. Meanwhile I got tire low messages leaving for work this morning and going to lunch today. And it is not cold out today. Its a wonderful nice sunny day. </div></BLOCKQUOTE>

As I stated in the other message, tell them to get an engineer out there or spend some time in replacing all the components, including the BCM.

Hi f5fstop,

have been having the low pressure alarm coming on. Called the dealer, the service person said, " oh this is the most common problem, I hear about this all day long." "Yeah well, you have to understand how the system works. (going into an almost breathless exhausting explaination)When she finished I asked her if GM was planning on correcting the issue. She said "oh no, it's just how it is....there is nothing to fix".
" Oh ok,thank you," I said, "can I have parts please?"

I really like my dealer, but thats just plain silly.

What is my next step? Save my confrontation for when there is a fix???

To be honest it is a large problem, but 99% of the time it is due to under inlflated tires, not equipment. Yes, some sensors can go bad, and if the tires are properly inflated, then something needs replacing.

Well BeeBe's tires are properly inflated, checked, checked and re-checked.

I've tried 40psi, 38psi, 35psi. Same thing same thing.

As I said before, my tires were all exactly 2 psi low (33 psi) when my alarm went off. Not something I should just "live with" GM should FIX it!

I have noticed that my light comes on every morning (below 50 degrees) only after I deliberately had the tires low.

So they are fine for a while then if I go off-roading and lower them then air them back up, the next cold morning they are low again but actually the tires are about 36 PSI.

Anywho, I took the trunk to this guy at cartoys and he did something to stop the dinging.
Now it doesn't ding at me all the time. Also the lights left on or door open won't ding but I don't care.

So it can be disabled but I am useless to know how.
