07 Tahoe LT3. Driver's side front tire sensor apparently has went out. I called the local dealership and was told there is a gray area with fixing these under warranty. He said I would have to approve him going in and taking a look to see if it needed to be replaced or just fixed. He said if the existing part needed to be fixed it would not be under warranty and I would have to pay for the 1/2 to 1 hr labor fee they charge. Seems a bit rediculous to me that theres a difference. Anyone had this issue yet?

 

There is no "gray area" when it comes to diagnosing and repairing the TPM System.
The sensors can be checked for proper operation without having to break-down the wheel/tire, the sensors are covered 100% under your GM factory 3/36,000 warranty.
I would be curious to know what the dealer does to "fix" a broken sensor.

 

Probably relieves the customer of about $80.
