Looks like the issue I'm having with the Tire Pressure Monitor and Key fob not working has been going on for along time. I'm 1 week over the 3 year warranty protection and they are wanting $710.00 to replace TMP module, door lock receivers and calibrate the key fobs. Needles to say I'm not a very happy GM person right now. The issue has been going on intermittently for over a year, with the tire pressure readings not working along with the key fob. Checked both fobs, same thing. When I did discuss with the dealership they said if the issue was not present when I took it in they don't have anything to check. I get it and understand, however, it appears this is not an isolated issue. The dealership urged me to call GM to see if they would consider covering as it was so close to warranty time frame. Any comments?
