From a liability stand point, I'd call the dealer, and explain that it seems to have "unintended accelleration" issues, and that you are worried that it might surge at the wrong time, and slam you into someone, etc...and that they should TOW IT to the shop to take a look at it...and give you a loaner while they figure it all out.

 

Now this is different.

Some one complaining of too much power........

Seriously...listen to the others....get to the dealer

 

Torque converter working TOO well?

X25: Bring it to the dealer - they'll get you all fixed up and you'll go back to loving your new Jeep.

 

I know this will sound stupid, but...my wife had similar issues with her Liberty.

Check your floor mats. She still has a red face over that one.

 

That is kinda funny right there!

 

thanks everyone for your opinions. i am definately taking it to the dealer for sure. my first thought was that it may have been the gas peddle getting stuck on the floor mat. yesterday when it happened again i got worried as i was pumping on the gas peddle and that was almost not working, it took a couple seconds for me to be pumping the peddle before it finally idled back down.

 

If you are pumping the pedal and it is coming back up with your foot this is not a floor mat issue. Along with others, only the dealer can help you here. I suspect the sensor for the pedal or the motor assembly for the throttle is bad. Both are warranty items. I also agree that your should use the words "unintended acceleration". Post back if your dealer blows it.

Now stop driving around! Go to the dealer and drop it off or have it towed.

 

explain to the dealer the scenario in great detail as to what is happening. I think others here already covered the varying options of what if it could be. I'd suggest getting behind the wheel at the moment is a safety issue at this point. something is sticking and there are to many points where this could happen all the way to the throttle cable connecting at the engine. Computer is more than likey in need of aflash which does not take long and as stated earlier it probablly logged an error code as to the cause of the issue. Look at mechanic tech section and diagnostic codes are available there if you want to see if one was logged.

 

I thought the JK had "DBW" Drive by wire? I don't have mine yet but for some reason I recall reading this...

 

WOW, this is a strange one.
Normally in the "drive-by-wire" system there are two position sensors attached to the pedal, and two position sensors attached to the throtle body. This redundency is for safety.
The pots attached to the pedal transmit an input signal to the electronic control module (ECM), which in turn sends an output signal to the servo motor on the throtle body. As the throtle body opens the pots there send a signal back to the ECM denoting position. Once position of the pedal and position of the TB are the same, the signal is then cancled out through the ECM, and the TB stays at that position untill the ECM sees a different input from the pedel sensors, (either positive or negative). There is a bit more to it than that, however that is the basic control.
Although I've heard of a few cases of this "unintended acceleration", it is the first I've heard of a case with a Jeep.
There are a few cases still pending which are being investigated by the Center for Auto Safety.
$80 million was awarded to a Missouri couple who claimed thier 93 Olds Cutless had this happen which resulted in a crash. The claim was awarded in 2003.
At any rate , since this is such a big safety issue, take that Jeep to the dealer ASAP.
Your discription would lead me to believe that somehow the ECM sent a bogus signal to the TB servo motor, ignoring any inputs from any of the position sensors.
THAT IS INDEED A SCARY THOUGHT.
