problem #1

Dec 192009

Silverado 1500 Hybrid 4WD 8-cyl

  • 5,000 miles
I hear a high pitched whining noise under the hood. Varies with engine RPM, vehicle can be parked and you'll still hear it. Only happens in extreme cold situations, usually sub zero. I live in fairbanks. Other than the noise, vehicle operates just fine. It can be quite loud. This problem is intermittent. Haven't been able to make it to the dealership while it's happening. Dealership suggested changing the heat setting from floor/dash to just floor. That fixes it. Apparently this isn't enough info for them as they don't know what to fix. I wanted this on record in the event something broke just after it went out of warranty. Currently approaching 25K miles on the truck.
