I have a 2002 Olds Alero with 80,000 miles and a V6-engine. About a month and a half ago, I had the transmission flushed, changed the fuel filter, and got new break pads and rotors. A couple weeks after I had these repairs done, I started to hear a humming noise while driving. It starts out low when I hit 15-20 miles per hour and increases in both pitch and volume the faster I drive. Also, I've noticed a dramatic decrease in my miles per gallon. Before the repairs, I was getting about 28 mpg (mostly highway driving). Now I am getting only about 20 mpg at most. I took my car in to ask about the noise and the decrease in mpg and they said I probably needed a couple new tires, so I purchsed two Yokohama tires. The noise has not stopped and I am still getting low mpg. Also, I change my oil regularly and I have not been advised to perform any other maintenance. Does anyone have any suggestions?
have the same problem?
