Last week, my bride returned from a trip to the store, reporting an incident where she put the car in gear, and it bucked as it tried to move forward. It would move, but not very far and not well (bucking). She pulled over, turned off the car, waited a few min, restarted, and resumed normal operation. It sounded like clutch slip to me, and I suspected that it might be a programming issue with the transmission.

We drove the car for over week with no recurrences.

As I pulled away from a stop light yesterday, I experienced it for the first time. It would pull, buck lightly, pull, buck lightly, and hit a certain point in the RPMs where it seemed to catch and work just fine. It felt like a carbureted motorcycle with a vacuum leak. After a few moments, it seemed to clear out, and again, resumed normal operation.

Anyone else experience this? I've got 34k on the rig. I've had the cat and DEF injector replaced. Love the vehicle. Hoping someone else has encountered this and can give me a heads up of what to expect/look for.

Thanks!

I have had the shuddering/missing problem episodically since new. Historically, I would take it to the dealer and a software fix would solve the problem for a some months. Most recently, the shuddering (like the transmission was hung up between different speeds - say 40-50 & 60-70mph) has been occurring more frequently. Last month the check engine came on and it spend two and 1/2 days at the dealer. When I got it back the shuddering occurred between 60-70mph and I called the dealer. I called the factory and spoke to Dillard, who assigned a case number and promised to work the dealer to find the gremlin. Finally the dealer called back and said the mechanic thought it was the torque converter and to bring it in they would change it out when I was ready. I said ok, but indicated I would drive it some more to see if the problem persisted. I then drove it around 800 miles on two trips and it drove flawlessly. In the two weeks since the trip the shuddering has been become chronic and so, I scheduled a trip to the dealer - scheduled for 6/15/15. Today, while driving on a four lane road the Jeep had a shuddering/missing spell that was violent - thought I might have to have it towed - scared my wife. No check engine light, transmission temperature 195 - normal. We bucked home, got a friend to follow me to the dealer and left it at the night drop. The truck has 12770 miles, oil changed at the dealer every 4 to 5000 miles, is garaged and has never had any towing duties. John A Howard

Have had the same problem intermittently since purchasing 14 GC in Jan 2014. Now I see there is a service bulletin (TSB 09-008-15) which recognizes the problem called "Intermittent Engine Shudder While Driving". It references the problem is with the 2014 Jeep GC and Dodge Ram with 3.0 V6 Turbo diesel. I called my dealership and clued them into this service bulletin. They said before doing an engine rebuild per this TSB, they would like to try adding "sea foam" to the oil over three oil changes. I'm not sure about this. Any one heard of "sea foam" correcting this issue?

The shudder TSB, requires the replacement of the heads, etc. My shudder experience was extreme at times and my dealer agreed to install the news heads. But, what was thought to be a week long effort, at best, turned out to be a two month ordeal. The mechanic explained that the instructions regarding this TSB was not really adequate and apparently no one has had any experience with this engine - it is new. Someone posted a reply that indicated a dealer in Colorado was able to do the fix in 5 days. JAH SR

Mine goes in on the 5th to investigate this shudder problem, the wife will not be happy if it has to be gone for the head replacement.

Interestingly we've not seen the problem since the colder weather has come in.

My guess is that the head replacement will solve your problem. But, my Jeep was in the shop for 2 months. I took it in on August 17th and the dealer called me on October 17th to report it was fixed. At some point during this ordeal, the mechanic told me the instructions for the repair were just not adequate - that there was a lot of additional information needed to comply with the TSB. He said he had had to do a lot of independent research. I was later told the Dealer had to order additional unspecified parts in order to complete the repair. On the other hand, someone reported in this forum that his Colorado dealer completed the repair in 5 days. JAH SR

I think Chrysler/Fiat needs to 'weed these dealers out' . Again- looks like best to 'research dealer' before you make your purchase! A suggestion would be to make sure they sell commercial trucks - and have a 'qualified diesel mechanic' on board.

The dealer did have two qualified techs who worked on diesels. It seems that the dealers have had a lot of experience with cummins diesels and I was told that Cummins had a support tech center in Atlanta. So, if a dealer had a problem with cummins, Chrysler would pay Cummins to help resolve the problem. Apparently the VM Mortori diesel is somewhat of a different animal. I think Chrysler should have taken a more active role supporting this TSB. JAH Sr
