It was bought in 2011, and ever since me and my wife are so sick in tired of buying and buying and buying these valve stems that are junk and it looks like 15 dollars to buy but its 60$ to put in..this is garbage completely useless.. you fill the tire up and you can hear the air come out of it its like a every couple of months I've had to buy one now I think its time to say something this should be a recall to put regular old fashioned valve stems and take them TPMS out of the cars/trucks some people cant afford these things every couple of months.

Vehicle has 31K miles. A flat tire occurred and the vehicle was taken for repair. The repair facility indicated that they could not repair the tire since the tread had reached through wear bars. This vehicle has been properly maintained with correct tire pressure and tire rotations. No accident or injuries were sustained as a result of the incident but the tire wear was not an issue at the last service, and if it were not for the flat tire, would not have been noticed until the next service which would have occurred after the start of the snow & ice season. Tire was on the right rear. Left rear tire also showing considerable wear, just short of the wear bars.

While operating my 2007, Chevrolet Trailblazer, I notice that the vehicle was leaning on the right side, I stopped the vehicle and after checking the tires I found no flats, and no air missing, as I drove away I began to feel a wobble in the front tires, which led me to meyer Chevrolet, where he found that the shock absorbers where still good several weeks later the leaning and the wobble continued and I took it to my mechanic where he found that all the shocks where leaking and had worn out at 33000, miles, before replacing the shocks I called General Motors to see if they can set up an appointment with another dealer which they stated that I should return it to the dealer I purchased it from. I then returned the vehicle again to meyer Chevrolet where again I was told that they where good and not bad, I continued to drive the vehicle and the tires where so bad that I decided to take it to my mechanic for an inspection of the front end which he found that the four shocks where bad the tires, and the alignment where bad, I then called Chevrolet to ask for there assistance in the costly repairs and they stated that because I had my repairs done elsewhere they could not help, so 1400 dollars later my car is running good again lets see how long before something else goes wrong. Last year while driving to Virginia beach, I stopped to refuel and when I got in the car again the gauge had stopped working, the little yellow light came on and would not shut off giving me false gas readings that the tank was empty, when I arrived in Virginia beach I called the dealers for an appointment and no one would repair it they said take it back to New York city for repairs. I then placed a call to on-star and they said unless you get stuck you will have no choice but to take it back to New York for repairs, we will send you a tow truck at that point and left me with a car that I didn't know whether there was gas inside or not. GM get it together.
