I don't think they replaced anything. I originally had an appt scheduled for tomorrow for them to look at it again, but I cancelled the appt. I am now working with my original salesman to attempt a trade-in for a replacement H3. I am done messing with this lemon (see my axle replacement thread). I will let you know the outcome.

HummerTech, does it effect anything if you don't do anything about the TPM?
