I just bought a 2013 Range Rover Sport and have only had it for a few days. Three times so far the engine starts surging while I am stopped and I have to press really hard on the brake to keep the vehicle from moving forward. Then after a few seconds it goes away. It only seems to happen when I am driving at low speed and then stop. This is a Certified Pre-Owned vehicle so I will take it to the dealer for repair, but I wanted to get an idea of what is causing it. Interestingly, when I drove the same model at a local dealership it did the same thing, so I'm thinking it must be an issue with the 2013 models. My vehicle only has 29,000 miles and when this happens it feels like someone is flooring the accelerator while holding the brake. A little scary - my wife is afraid to drive it.
