Howdy all,

I'm hoping someone could help an old guy understand a thing or two about some issues I'm having with my Impala.

Over the past couple of months, the "Service Tire Pressure Monitoring System" has started to come on intermittently. When this happens, the right-rear tire always shows as -- where the other 3 tires show typical 33-37psi readings. I recently replaced two tires, and had the fronts rotated to the back at the same time... TPMS signal still shows the right rear tire as faulty.

Assuming there is a problem with whatever unit receives the signal from the TPMS sensors (which is covered under my warranty), I took it to the dealership to have a look. They told me it was a bad TPMS sensor (which is NOT covered under my warranty) and they'd be happy to replace it for $175. I explained that the issue didn't follow the tire when they were rotated, and the reasoning the service manager / technician gave me was that the place where I had the tires rotated either didn't relearn the sensors correctly, or didn't do it at all. (I know for a fact that they did it, I was sitting in the waiting room when I heard all four "beep beep"'s from my car, notifying that the sensors were relearned.)

The dealership relearned the wheels themselves, and sure enough, the same tire is still giving the same error. Next time I am in, I am going to have them rotate the tires and relearn the sensors, then, if it follows the tire, it will prove to me that their diagnosis is correct. If it sticks with the same wheel location, then it should prove to them that it's the receiving unit (whatever the name of the module that receives the signal from the TPMS sensor is called).

Well, to add an additional symptom, this morning, my key FOB stopped working. I replaced the battery, still didn't work. I tried reprogramming it with the new battery and it wont take.

I called the service manager this morning to tell him of this new symptom, and instead of just accepting this as further evidence that the receiver unit is failing, he suggested that my key FOB needed to be replaced as well.

I'm having a very hard time accepting this diagnosis, and I'm hoping a third (impartial) party might be able to convince me that I should.

Thanks,

Jerm

You could, but you'd be better off just finding a new dealer who isn't trying to screw you.
