When we start the GMC Envoy and start to drive about 1-2 blocks away from the house we notices a vibration or a buzz noise. This seems to happen as truck is getting up to speed. It buzz or vibration only happens for seconds. Once the truck warms up the problem goes away. I have checked all fluid levels and tires are good. Any idea what maybe causing the problem?
