2010 Jeep Liberty • 6 cylinder 4WD Automatic • 19,971 miles

When I started my 2010 Jeep Liberty this morning, the engine was loud, and the RPM's were approx. Double what it should be. At each stop light, the Jeep wanted to move forward, even though the brake was applied. In addition, as I removed my foot off the brake, the Jeep would hesitate, then abruptly move forward. I am fearful that the engine will "blow", and the dealership is closed. What is the problem. The vehicle is not even 11 months old, and I need my Jeep!

First check to see if your floor mat is impeding your accelerator pedal in any way. Second look at the throttle plate (out on engine) to make sure it is fully closing. Beyond that you should be under warranty
