2004 Denali - Has anyone ever experienced this? It is hard to explain but it happens when Im cruising down the freeway and I ease onto the throttle. I get a high frequency vibration in the gas pedal that is comparable to a foot massager. It's a crazy feeling. It has only done it twice and both within the last month. If you let off, it stops but if you ease back on it continues then it slowly just stops and the pedal is smooth as glass again.
