 The "esp inoperative" message pops up frequently,<p class="MsoNormal">even when the weather and road conditions are warm, dry and clear. When itoccurs, the car seems to loose acceleration (power) and slows down (rather veryquickly on roadway sloping up). Pressing the gas pedal would not speed up thecar immediately; it would after a while. When this occurs, i pull over the carand turn it off & on to get rid of the "esp inoperative" message.This has happened on high speed expressway as well. It felt very dangerous andunsafe since a truck was approaching closely behind. I was fortunate to pullover on the shoulder and turn off/on the car. This appears to be associatedwith a faulty part, sensor or software that needs to be fixed by the carmanufacturer. I bought this car brand new in October 2014 and it currently has5940 miles. It was serviced by dealership in October 2015 for 12-monthmaintenance. This problem is very dangerous because the SUV<span style="mso-spacerun:yes">&nbsp; </span>loses power while I'm on the road. Thisproblem should not even occur once. It is a life threatening issue.</p>
