I am considering the purchase of a 2007 EX AWD Element, but there is one thing that makes me pause. During a test drive, for a brief instant or two, there was a a short series of hesitations. (It felt like driving on a rough road, but the pavement was definitely smooth.) This happened twice, with the two episodes separated by a few seconds. During each episode, there were probably about 5-7 hesitations, each lasting less than a second each. I was driving less than 30 mph, and I had been driving for less than 10 minutes. I have driven it a couple more times since , but I have never been able to reproduce the same behavior. :? I even re-traced the same driving route. (I have also had it on the interstate at 70 mph, and it is smooth as silk.) Should I be concerned that there is a developing engine or transmission problem? Any ideas from experienced owners? Many thanks!
