Throttle malfunction!!!!

This morning I was driving to work, up a hill and going about 55 on the highway, when the throttle completely went out. I was in the center lane and was barely able to get out of the way and on to the left shoulder before getting run over. The engine was still running, but the RPMs never went above idle no matter how far I pushed the gas pedal down. I shut the engine off and cycled the ignition as the owners manual suggested, but nothing.... Now the dealerhip says that they are not responsible for providing me with transportation so I get to pay for the rental out of my own pocket. I am not a happy camper and am actually on hold with the Crysler Corp right now.... Has this happened to anyone else?

UPDATE: I just got off of the phone with the Chrysler Corp and they said at this point the dealership cannot diagnose the problem. Apparently everything checks out normal.....EXCEPT FOR THE MINOR ISSUE THAT THERE IS NO THROTTLE RESPONSE! They also mentioned that they would not reimburse me for rental car expenses, how nice of them.

That sucks, when my GMC was in for warranty work they gave me a brand new unit to drive until the repair was complete.

Is it automatic or stick?
Not a nice situation to be in. Any feedback from the dealer?
Computer, linkage, fuel, anything???

It's stick. The dealership said "We've hit a roadblock, we cannot determine what's wrong with it at this point!?" It has to be a computer issue. New Jeeps dont use throttle cables or linkages anymore, it's all electronic now. The fuel is still there because the engine never shut off, it was still idling.

Fly by wire throttles should set a p2100 and up to 2135 code when there is an anomily....is there a code in the system.....most times FBW problems are a pretty straitforward diag......the system is rerally quite simple a sensor sets a signal to a stepper motor in the throttle body which opens based on how far you are commanding with your foot.......g

I just spoke to the dealership again and they said that they are on the phone with Star, I have no idea what that means. In short, they still don't know what is going on.

Star is Chryslers Technical assistance phone line....Us techs call it when we are lost..... .......which we avoid cause it means sitting on the phone listening to bad elevator music for upwards of 45 minutes before ya actually talk to a human who often knows less about it than you do

Gary, is this a bad sign? Since you're a tech, have you dealt with this problem before?

Fly by wire systems are having lots of problems in ALL manufacterers, not just DC. Toyota, BMW, GM, everyone is having problems with TBW. Most the time is is heat related, but thats just a very general statement. Anyway, It may not make you feel any better, but this is a semi-common problem on any new model vehicle with TBW. Glade your ok. Sucks about the rental car, but get used to it!! Jeeps are great vehicles off road, and a blast to own, but their customer service and warranty work BS is the worst thing you will ever deal with. I have almost sold my Jeep on more than one occasion because of the dealers around here, and only did not because of all the stories I read on the inter-web about the same situations all over the globe at these "5 star" dealers. If you can find a good dealer, KEEP THEM

Now the dealership is saying that everything is functioning as it should, but they have been directed by Chrysler not to release the vehicle to me because they are unable to determine what caused the problem and if it will happen again. Still paying for a rental..........

Finally got my Jeep back. Service invoice states that P2167, P2166, P2116, P2115 were the codes that caused the problem. Everything seems to be working great now.

Nope, they did NOT change that. It will only read the POWERTRAIN codes and not the BCM, SKIM, TCM codes. You really should have a scanner to properly diagnose one of these vehicles. Codes really do nothing but to HELP assist you in finding the problem.

Maybe I'm missing the obvious . . . . .but what was the reason(s) for changing to a fly by wire throttle?

to make things more complicated than they need to be.

The more the computer can control of the vehicle, the more geeks can control fuel efficiency, drive train life expectancy and even now handling. In a street car it can be very beneficial. off road it can be very irritating.

Ah crap, this is in the JK section again. sorry, forget I said anything.
