Hi Gang,

I've recently purchased a 2009 G8 GT with about 26000 miles on it. After I got it home, the TPMS kept faulting out. Took back to dealer, they did the reset, problem persisted. Took it back, the replaced 3 sensors. Problem persisted. Took it back and the removed the rear tint and replaced the receiver. The problem still persists.

It seems that I drive it for about 20 miles then the fault appears. After the car is shut off for a while, the fault clears. I have put it in engineering mode and when the fault comes up even there the psi goes to --. it is currently at the dealer and they are waiting to hear from "tech support" to help identify the issue. I know some have had issues, but is there any clear answer to this.. Is this a persistent problem. Tires and wheels are stock.

Thanks in advance!

You can go to your dealer and have your TPMS reset.

You can go to your dealer and have your TPMS reset.

I've been back to the dealer a few times. Resetting does not do the trick. it's been back to the dealer a few times and 3 of the 4 wheel sensors have been replaced, and I believe that the unit has been replaced as well. Still...after 20-40 min, the tpms fault comes on. It is not always consistant though so I am not sure what the problem is. The last time I went to the dealer they said they could not reproduce the problem. Thinking of taking it to a buick dealer that used to sell pontiacs. Perhaps they know of the issue and can correct it.
