Having an issue where when I am shifting into second, as well as third gear and then proceed to cruise between 2000-3000RPM for whatever reason I am feeling small jolts, as if something is catching an then releasing/ tapping on the gas feeling where it accelerates and then let's go even though I am not. Really hard to explain. It was doing this yesterday noticeably and not at all today. Also noticed it off and on on a recent vacation of about 1200 miles. No idea if I should take it in for repair or not as its off and on, but it has been not so minor lately, very noticeable catches/jolts if you will, but off and on. New car and still has extended warranty.
