On vacation while using the cruise control, I hit the brake pedal to turn off the cruise control. The car started to slow down. I then pressed on the gas petal and it was very stiff and hard to press down. I wanted to get control of the car myself instead of using the cruise control. I turned off the cruise control but no good. The only way I could get control of the gas petal was to pull over to the side of the road and come to a complete stop(or very close to a complete stop), Then the gas petal worked as normal. We are still on vacation so I haven't taken it in for service yet. I just don't use the cruise control. But the problem doesn't happen all the time. I searched the web but found now hits on this type of problem so far. The car is one year old. Thanks.
