must be a computer glitch, disconnect the battery overnight, this should reset the computer. may not work, but well worth a try.

I think unclebob has a good point here. Unless I am totally confused, the 4 LO is activated only by the big lever and you have to pull a bit hard on it. If you think you are in 4 LO because the light is on but you didn't pull the lever then it most likely is an electronic glitch.
I have a call in to my favorite mechanic at the Jeep dealer. This guy is sharp, he was sent to school for the CRD as soon as the dealership learned it was coming out. This dealer works hard at keeping the five star rating. My mechanic has changed one EGR in 117k miles so you know he put in the right one first time. His work under warranty has been flawless. He will know what to make of this.
I suspect something is mis-communicating between the engine computer and the body computer. It might be shifting the transmission to a low gear and turning on the 4LO light. I am just guessing because I can't be there when it happens. You said NO GO so that could mean a couple of things.
Like uncle bob suggested let the Libby sit with the battery off overnight and hopefully the problem will go away. Please let us know either way.
Good luck with that problem, glad you like your CRD, I sure like mine and all of my friends who have driven like its agility compared to their bigger units or its quickness compared to their small cars.

Thanks I will try disconnecting the battery It did it about 10 times today It does actually shift all on it's own no lever pulling this would be great if I was climbing a mountain when the light comes on the RPMS shoot up and pushing the gas pedal feels like sludge Could this be doing damage??????? I was thinking of driving it in 4All time for awhile but will kill the mpg Wish I had a mechanic like yours Mine told me not to buy mine when I had it inspected he couldn't find anything wrong just didn't like Jeeps and suggested a Honda CRV Needless to say I didn't pay for his opinions I love my Jeep I will let you know if the battery disconnect has a positive outcome Thanks again unclebob and biodieselman

I forgot to ask you if the dash light is coming on to indicate it is in 4lo or if you assume it is in low because of the high RPM.
This might be just a transmission bug. I was made to believe it could not (should not) go into 4 lo unless the 4 lo lever was pulled up. If that is correct then I suspect it is the transmission shifting to a lower gear.
Hopefully leaving the battery off with cure this problem before the engine or transmission is seriously harmed.

Have you checked your transmission fluid level?
and are you using a good synthetic fluid?
I recoment putting in a Transgo shift kit, next time you change the trans fluid, it is not very hard to do and costs under $50 if you shop around.
Another thing you might check is your motor mounts.
put on your parking brake, have someone stand next to the open engine compartment (never in front of the car) and give it come gas. (not much) in both forward and reverse. The engine should remain stable. If it tries to lift up out of the car, you have a broken mount.
the reason I am thinking this is enough movement might cause it to shift into 4-low. I kinda doubt it, but it' a free check!
Best of luck: bob

I just read this post and had to chime in my thoughts. I purchased one of the first CRD's on the lot in 2005. I now have 98M on it and other than the EGR problems that I think every owner had when they first came out, I have had zero problems. I pull 3 different trailers with it on a regular basis and can say that this engine/vehicle combination has the previous truck I owned beat to pieces! I sincerely believe that having grown up with diesel engines on a farm have helped me know how to maintain and drive a diesel vehicle. Diesel's are a different beast from a gas engine and learning to "let the engine do the work" instead of constantly thrashing the throttle to floor when you need power, is something that many owners never learn. A short "warm up and cool down" period is also something that I do religiously. There isn't another vehicle on the market right now that I would trade for ...and possibly won't be until some maker comes out with another "smaller diesel".

I'm glad to hear you are happy with your CRD. Mine has been very reliable since purchased new. I am fortunate to have a five star dealer close by who sent his mechanic to school as soon as he learned the CRD was hitting the market. The guy knows his stuff. My first warranty issue was the EGR. Thankfully, I got a stainless one right away. It is still in service now at 116 K miles. There was a ball joint and torque converter recall which was only a minor inconvenience. the dealer had a rental car waiting for me. I suspect he added that cost into the warranty claim.
Other then that there have been no problems I can attribute to the Jeep itself. I had a fuel problem one time. Left the house in cold weather, got five miles away and........no power. It could run at about 35 mph. I suspect the filter was due for a change so it was partially clogged, but worse yet I think there was water in the fuel. I limped to a truck stop about 15 miles away and added a double helping of Howes diesel treatment. Tired of pulling off the road every time a car came from behind, I went inside with the engine idling, doors locked, and had a bowl of soup. I always keep a spare key in my pants pocket. By the time I came out the Howes had done its thing. I got in and the power was back. So now I add it at least every other tank even in summer and ALL fill ups in the winter.
I have good luck using 20% biodiesel IF I add the Howes every time. I like knowing the pump and injectors are getting proper lubrication that the missing sulfur USED to take care of. It runs great on it, I don't notice any great difference in mpg so I use it every chance I get. It can't be bad news if I have driven 116,000 miles using it.
I hope they can get this little dynamo cleared to pass emissions for more Jeep vehicles in the future. I have talked to a lot of Wrangler owners who would dearly love to have that engine in a Wrangler. That would be an awesome stump jumping, rock crawler with almost 300 pounds of torque at just 2000 rpm!
#121 of 178 106,000 and still going
Dec 22, 2011 (6:53 pm)
106,000 and it's still going strong! It just got the transmission fluid changed a couple of months ago and I installed the Fumoto oil drain valve P/N F102N : PF-3/8 http://www.oildrainvalve.net/f102n-pf-3-8/.
#122 of 178 101M with Zero problems!
Dec 22, 2011 (7:29 pm)
I have just under 101M on my 05 Liberty CRD and have never enjoyed a vehicle as much as I have this one! I've ran the recommended Mobil oil since day one ....have changed the tranny fluid 2X as I pull my Kawasaki Mule on a tandem trailer on a regular basis. Fuel economy has been great ....low 20's pulling my trailer and 25 -27 MPG average when not pulling my trailer. The only thing I have replaced is the alternator which went out at 98M miles ....I can't complain about that. I'd purchase this vehicle again if a small diesel were offered. I also have a '97 Wrangler that I wish had this engine. I'll only have a diesel in my next vehicle so until something else comes along, I'll have to keep this one running! I have a close friend that also had a CRD and just sold it a month ago so he could move to a larger vehicle ...he went to a 3/4 t. Dodge with the Cummins ....but only because he needed a larger truck ...he also loved his CRD and hated to see it go.
