NHTSA Complaint #11420730 — 2009 CHEVROLET SILVERADO 1500

I have had the Tire Pressure indicator that tells the tire pressure of all four tire replaced several times. John L Sullivan Chevrolet in Roseville California keeps telling me that they are wearing out do to use. But the truck only has 70K in mileage and I they malfunction all the time. I get readings of 99 lbs of air pressure. Then the same tire will say 0 lbs of pressure. And it will say 7, then 29 then 18 lbs of air pressure in a distance of 2 blocks traveled. This is a malfunction due to faulty parts in the GM tire pressure reading system and they need to fix it. If I take it to the Chevy dealer, they want to charge me $209 to per tire to replace them and then they still do not work after they replace them Still get crazy tire pressure readings and it warnings flashing on my instrument panel that are distracting and dangerous. It does not flashes every 5 seconds that I have a tire pressure issue and it needs to get resolved. But Chevrolet will not do anything but charge money of there problem with their truck part that is malfunctioning.
