Bill 2/16/2011If your mileage is only 4,545 miles is it still under warranty? If so, get an oil change if been awhile. Recomend changing oil every 3-5,000 miles or yearly, whichever comes first. This will avoid dealership from saying oil dirty, maintenance not properly done, your problem not ours. If you actually only drive this many miles I would use synthetic oil also. Changing oil may just cure the problem, and check oil level on dipstick now to see if at full mark.
