The automatic belt tensioner pulley is in the process of going out. The pulley itself is slowly suffering from a high pitched whining noise which is caused by bearing failure. With the current mileage the part in question shouldn't by any means be failing, the tensioner works fine but the pulley wobbles a bit too much. If the pulley continues to wobble more and finally results in catastrophic failure it can shred the serpentine belt which will render the vehicle useless or even become a danger to any and all occupants in the vehicle especially if it fails on the highway. If the belt goes out it can bend other pulleys or shear off pulleys, bolts, or even bend the harmonic balancer (engine vibration dampener) which would result in a blown or seized up engine. I'll also add that the belt could cause a fire if it gets wedge between other spinning pulleys at the time of the pulley's bearings overheating and the pulley either breaking off or causing the belt to shred.

This is a dealer demo vehicle, first 2235 miles were demo. During my first morning (12hours after picking up at dealer) of ownership I was descending down a hill with the cruise on, and the vehicle proceeded to over speed approximately 5-7mph. I travel this hill both ways to/from work daily and this happens everytime. I though this might be an abnormal adjustment within the computer/etc so while taking in to the dealer for a TPMS (tire pressure monitor system) issue I mentioned the overspeed issue to the service write up and they said that it was normal. I don't agree, but maybe it is. It does adjust back to normal cruise set speed but is unique. I had a 2002 dodge ram 1500 previously and it did not do this, and I have drove otr (over the road) semi-trucks and know the difference with overspeed being normal and abnormal. I would like this to be looked into, as it could be a hazard that could lead to unsafe situation.
