Karen Healey (Rutland, Massachusetts) - 4 Jeep Liberty
Noise... Her car sounds like flatulence, expelling air--sounds like it's coming from underneath, in front of her. Can happen once or twice a day, doesn't affect performance, check engine light is not on. Could be the ABS pump coming on, and a possible sign it's on the way out. It's probably okay for now, but if ABS light comes on, take it in ASAP and get it fixed.
