There is a small pin hole in the radiator that the dealership advised was created because of a problem with the thermostat. Apparently GM is aware of the problem and will fix it if it's prior to 60,000 miles. I am several thousand over now and they refuse to cover any of the $1100 bill to repair

On two separate occurrences, w/ family in the vehicle, starting speed at approx. 35mph, the accelerator (gas pedal) stuck to the floor during the process of passing another vehicle during city street driving. Top speed got to approx. 55mph, w/ stop lights fast approaching. The pedal simply would not release from full throttle until after the vehicle finally came to complete stop with brakes applied, shifter to neutral position, slamming the shifter to park, and ignition was turned off! had to take immediate and decisive emergency actions during both situations! the first time it occurred, thought perhaps the rubber floor mat may have contributed to this event; however, driver side floor mat was immediately removed. Several days later, during similar operations, the accelerator (gas pedal) again stuck to the floor board in full acceleration mode w/ family in the vehicle! currently have appointment set-up at a huntsville, al. GMC dealership. This truck was purchased brand new at laura Buick in collinsville, il. Although I realize there are other GMC customers; not sure why this huntsville, al dealership would not work me in sooner. This vehicle has approx. 49K miles and should still have warranty remaining until 68K miles. GMC service department rep. Stated, "Monday 26, February is first date available."
