Hi, all. I just bought a 2012 Liberty lattitude about 2 months ago. I love it, no problems. I,m new to Liberty,s. When i start her up in the morning or some times during the day, when i take off after warm up and i beleave when she shifts into 2nd gear. I hear a sound like a piston air pump running for a few seconds . Sound is only for a few seconds and then stops. I thought i read were there is some kind of a pump on the engine, am i right or wrong. Is this normal. I'm no mechanic. Thank's all.

Its right around 15mph, right? That should be the ABS pump doing a self test.
