Is anyone having a problem with Yukon driver's power seat adjustment electronics and gears going out. I've a '04 Yukon. At 40K miles the power seat adjustment gears (driver's side) started growling and at 45 K miles went out entirely. The dealer split the cost on it but was still about $400 out of my pocket. Now at 52K miles I'm getting the same growling from the gears when the driver's seat is adjusted, which is every time I open / close the door and pull the key out of the ignition. Thanks for any comments.
