Our 2003 Yukon XL has heated power front seats and power adjustable pedals. The front seat will only move about halfway forward (with "all the way" being the forward-most position that was possible when we purchased the vehicle--positioning the driver very close to the steering wheel). When you reach the point where the seat will no longer move forward, there is still track visible in front of the seat. On the passenger side, the seat moves forward until the track is hidden--and then keeps going several more inches. Also, when you reach the point where the seat will no longer move forward, it sounds like the motor cuts off. It doesn't sound like it's binding up and can't move forward further, it's just humming away, and then, completely silent, like it was turned off. But, I suppose it's *possible* something is binding up really quickly once a certain point is reached? I checked the track and can't find any obstruction. A few weeks ago, it was working just fine. We noticed this because one of the drivers for this vehicle is a smaller girl, and she needs the seat all the way up. She can no longer drive the vehicle because she can't reach the pedals with the seat only halfway forward. Also, the power adjustable pedals do not work. When you press the "forward" (i.e., away from the driver) button, you hear a click and there is no motion. When you press the "back" (i.e., towards the driver) button, there is no noise and no motion. It's not critical that we get the pedals repaired, but I mention it in case it is related to the seat. I don't know how long the power adjustable pedals have not been working, as we never used this feature.
