Transfer case malfunction part is unavailable to buy. This seems to be a widespread complaint for my make model vehicle. Service 4 wheel drive system shows up in the computer screen to warn you of the problem vehicle will not shift into 4 wheel drive low. Appears to be a faulty gearing or electrical transfer motor.

After receiving n23 recall software update, when attempting to engage 4wd low in a low traction situation, the transfer case motor would not shift due to damages resulting from the software change. The software update was issues to bypass problems occurring from an often damaged part, rather than repairing or replacing the part itself. Because if this, the software change has negatively affected numerous vehicles 4wd low capabilities, rendering them useless in emergency situations.

Transfer case malfunction. . . . Says "service four wheel drive system soon" on the dash computer. Does not go away. No part available to repair. Jeep says thousands are on back order.

Jeep n23 recall to fix inadvertent shifting of transfer case into neutral locks up control module. Vehicle transfer case will not shift anymore. Chrysler denies the effect, although thousands of jgc are now crippled. . Read more...

This Jeep had the n23 recall done and I posted earlier about the ongoing problems not going into 4 lo and neutral. . . But the problem is worse than before the recall and is a safety issue now. This problem is worse on mine than I first thought. But if the intent by Chrysler to solve a safety problem with going into neutral unintentionally, was the reason for the recall, they failed. I just did some tests on my 08 gc and found: ignition on, motor off in any gear but park and the transfer case is in neutral. In park it's locked. Motor on, the transfer case won't go into for 4 lo or neutral and the service "4 wd" comes on immediately when trying to go into 4 lo or neutral. My scanner shows no codes, and the message on the evic disappears once the Jeep is off and then restarted. In summary, if the Jeep stalls and the key is still on, the transfer case is in neutral!!! this is more of a safety issue than before.

Took the vehicle in for a noise that turned out to be a bearing problem. While in they indicated that an internal transfer case seal was leaking. I am being told that that type of failure is very common with this type of vehicle. If unnoticed could cause a failure.

While driving my car suddenly would not go into gear, I had to put my car in neutral my driving. Engine light came on as well. This happened approximately three days after I had the recall done for the transfer case at champion Chrysler dealership. I took it back in July and they told me I needed a new transfer case which I ended spending a 1000 to replace. Picked up the car and as soon as I drove it off the same things happened. I had to shift to neutral before going into 3rd gear. Took the car back to champion chrsyler again and they said it was the solenoid. I just spent another 1000 to get that fixed. They said this should definitely fix the problem. Spoke to Chrysler corp. On first incident and service mgr no luck. Spoke to service mgr on 2nd fix and no luck. Long story short getting the recall fix cost me 2000 when it suppose to be free of charge. Chrysler's recall solution for the transfer case is costing consumers more out of pocket. I had never had to put my car in neutral before getting the recall done.

Chrysler issued a recall (n23) for problems with Jeep transfer cases shifting into neutral unexpectantly. I've seen no posts where this actually happened. Against my better judgment, I had the recall done. Immediately people started having issues with 4lo no longer working, and "service 4wd" messages showing on the dash. These are my symptoms also. People that flat tow the Jeep behind a motor home could no longer switch the transfer case to neutral (ironic huh?). What does Chrysler do? they don't even acknowledge their problem. A year after the fiasco started, the dealer that did my recall doesn't know about the issue? apparently Chrysler dealers loaded defective software or installed the software improperly. The software cannot be unloaded and reverted to before the recall. Chrysler's answer when I called 800 number yesterday, over a year since this recall fiasco started, was for me to pay the dealer to diagnose the symptom and if the diagnostic code is correct, they'll reload the software. . . After I've paid the service call! there are thousands of posts on line about the problems with the n23 recall, both on automotive sites and RV sites from owners that flat tow them. And Chrysler has their head in the sand. . . Or elsewhere. This is the biggest scam. Per the posts, Chrysler is charging people thousands to replace components when it's the recall that started the problem. The problem occurs immediately when trying to actuate 4 lo. It doesn't go into 4 lo and the service 4wd message occurs on the information center. I had to show the dealer the service bulletin number calling attention to the problem, from posts on the web. That tells me that Chrysler is not even informing their own dealers about the problem created by the n23 recall. And the quadratrac ii transfer case with the 4lo capability is an option upgrade. The recall takes away this functionality!.

2005 Jeep Grand Cherokee. Consumer writes in regards to transfer case actuator recall problems. The consumer stated he complied with the recall notice he received in the mail. The dealer reprogrammed the final drive controller module. Four weeks later, the vehicle caught on fire. The consumer stated he didn't have any problems with the vehicle, prior to the recall repair. The consumer stated after a short time of driving on the expressway, it felt as though the vehicle was not shifting into the next higher gear and would not shift into the higher gear when he pressed the accelerator. While driving in the right lane, the vehicle went into neutral on its own and the vehicle began to coast. When he looked in the rear view mirror, he noticed gray smoke coming from the rear of the vehicle and then the gray exhaust smoke, turned black. Within less than a minute, the consumer was on the shoulder and two-inch red flames began emitting from under the hood. Then the flames were five to six feet high above the car hood. The local fire department and police were called to the scene.

(xk) Jeep commander, the transfer case of our Grand Cherokee could not be shifted out of 4-high to 4-low. This was discovered while attempting to use the vehicle to launch a 7000 pound sail boat on a marina launch ramp about a week and a half after the n23 reprogram was made by an authorized dealer. This demonstrates the software is defective and potentially dangerous by creating an unexpected safety issue.

The contact owns a 2005 Jeep Grand Cherokee. The contact stated that while driving approximately 50 mph, the vehicle would not accelerate and the transmission failed to down shift. Additionally, the transfer case would not shift out of four-wheel high into neutral or four wheel low properly. The failure occurred after the vehicle was serviced under NHTSA campaign id number 13v175000 (electrical system , power train). The vehicle was being taken back to the dealer for the third time due to the remedy not correcting the failure. The manufacturer was not notified of the problem. The approximate failure mileage was 86,300.

This demonstrates the software is defective and potentially dangerous and may not correct the reason for the recall. The Jeep cannot be towed in neutral, and 4-low, a feature I specifically required in a vehicle, is now useless! this could have been avoided by completely replacing the fdcm instead of a poorly constructed software "fix. ".

Thousands of Jeep vehicles subjected to this recall have suffered the same loss of function. How does NHTSA, or we, know the safety problem is actually fixed? it is obvious the software used in this recall was not subjected to sufficient testing to validate it. I therefore fear my car is just as liable to have a safety defect as before the recall. There are several consensus standards for the testing of software, they were developed by ieee, ansi, iso and ul to name a few. We own a second Jeep Grand Cherokee. We refuse to have this recall performed on our second vehicle until this problem, and any others that may be hidden in the poor design of the software, are corrected.

I filed complaint (10561016) when the first Jeep dealer I went to would not honor the safety recall n23. The second Jeep dealer I went to said they would honor the safety recall n23. After going to the Jeep dealer they checked their records and advised me the recall was already completed on my Jeep Grand Cherokee. I was advised that my Jeep Grand Cherokee needs a transfer case actuator and I will be charged for this part and labor. In addition they advised this part is on back order. My Jeep Grand Cherokee's 4wd lo was working prior to this safety recall n23. I feel that Chrysler/Jeep should be held accountable for replacing this part. I intend to write my state attorney general.

Jeep shifted to neutral upon startup and rolled downhill in park. (Jan. 2013) note there is a recall on this issue Chrysler/Jeep "n23". I had not had the recall service performed. I scheduled the recall service, which was done at bosak Jeep, merrillville in, in February 2013. The service is a software update to the final drive control module (fdcm). The reason for this complaint is to state that the software update performed eliminates specific functionality from the vehicle, namely 4-wheel drive low range and neutral modes (Jeep being towed/transfer case disconnect). The elimination of these functionalities is creating a "black market" of owners who are swapping out the updated fdcms with pre-updated ones; and has initiated discussion of persons "hacking" the fdcm code to regain the functionalities. .

I believe this issue/complaint is a result of safety recall n23/NHTSA 13v-175. Ten days ago we were preparing to hook up my Jeep for towing behind our RV. When I attempted to put the transfer case into neutral it would not move and I would get a 'service 4w system' error message. We took the Jeep to the dealer and was advised the transfer case module was bad. The worst news was there were none to be found within hundreds of miles and I had no powertrain warranty. Ten days later and I am still waiting for a replacement part. This is the part that was 'reprogrammed' as part of the safety recall n23/NHTSA 13v-175. Ever since this reprogramming was performed I have no 4x4, no 4low or neutral. This is expensive to repair and we were forced to cancel our trip. Now, as a realtor in upstate NY I am not able to do my job as I cannot take buyers to properties on snow covered roads. My Jeep worked perfectly fine until this module was reprogrammed. Additionally, now I hear a thumping noise from the rear (it sounds like the rear,) when I first start out every morning. I see other Jeep owners are experiencing the same problem, and feel confident that this part is being replaced all over the us as a result of faulty reprogramming. . . And that is why they cannot get a new one. I do not want to wait till this problem causes other electrical issues, which it very well could. I believe Chrysler is ultimately responsible for this repair as my transfer case worked fine till they reprogrammed it.

The contact owns a 2005 Jeep Grand Cherokee. The contact stated the vehicle was serviced under NHTSA campaign number: 13v175000 (electrical system, power train) however, the recall remedy disabled the transfer case functionality thus creating another problem. The vehicle was taken to the dealer. The manufacturer was made aware of the failure. The vehicle was not repaired. The failure mileage was 95,000.

On 01/20/2014, I brought my Jeep Grand Cherokee 2006 to my mechanic due to a service 4wd system light on dashboard. My mechanic advised me that the computer revealed code safety recall n23/NHTSA 13 v-175. Safety recall n23 may unintentionally cause the transfer case to shift to neutral position without input from the driver. This condition could allow the vehicle to roll away inadvertently while the vehicle is parked and cause a crash without warning. My mechanic advised me to go to my Jeep dealership due to the safety recall. On 01/21/2014, I contacted via telephone the Jeep dealership where I purchased my vehicle. I advised the Jeep employee of the situation with my Jeep Grand Cherokee 2006. The Jeep employee advised that I would be charged for repair. I advised the Jeep employee that the code n23 was a safety recall. The Jeep employee responded by making an accusation that my mechanic's computer was probably outdated. In addition the Jeep employee advised that the code n23 was not a safety recall. Continuing on the same date, I contacted another Jeep dealership. I explained the situation with my Jeep Grand Cherokee 2006. I was advised by the Jeep employee that the code n23 is a safety recall and the Jeep dealership would honor the recall. I conducted further research to discover that on 08/17/2013 I brought my Jeep Grand Cherokee 2006 to the first Jeep dealership mentioned for safety recall n23.

I have a 2005 Jeep Grand Cherokee, took in in my dealer in Aug, 2013 for a safety recall (n23). First time I tried to shift it into neutral, it flashed a "service 4wd system", and would not shift into either neutral or 4low. Jeep forum, with 70 pages and hundreds of comments on this problem, looks like the recall software update is the problem and Chrysler has not yet owned up the issue. Meanwhile, I cannot use my vehicle as intended. My dealer says I need a $500 part, but others have had that replaced and still have the same problem. There are about 2,000 transfer case actuator motors on back order to correct this problem; however, many who have had this part replaced still have the same problem. The new part is not fixing the issue, Jeep needs to replace the final drive control module and the transfer case actuator motor.

The contact owns a 2005 Jeep Grand Cherokee. The contact received notification of NHTSA campaign number: 13v175000 (electrical system , power train) and had the recall remedy performed on the vehicle however, the transfer case actuator failed shortly after the repair. As a result, the vehicle would not engage in four-wheel drive. The vehicle was taken to the dealer where it was diagnosed that the transfer case actuator needed to be replaced. The vehicle was not repaired. The dealer informed the contact that the remedy part was on back order. The manufacturer was made aware of the problem. The approximate failure mileage was 185,000.

After my Grand Cherokee had the "n23" recall performed on it by the previous owner, the "service 4wd" indicator comes on and disables my transfer case shifting. I clear the codes and it works again for a short period of time then the codes return (c1406, c1405, c140f) disabling the shifting again. This appears to be a common issue with Grand Cherokees according to the information I have found on Jeepforum.

Took Jeep in for recall recall completed some odd miles down road 4wd low would not engage took back to dealer after internet findings of a bad recall( they make some by pass software instead of actually fixing the computer chip that cracks in transfer case) anyway they reset worked for a week mayb and again low didn't work anymore back to dealer they had new software Jeep was reflashed on way home service 4wd system light on all the time took back to the dealer they reflashed it again n told me they'd have to contact Chrysler if it happened again went out started Jeep lights back on and back thru the door into dealer now I gotta wait for some star technicians to come look at it who nos how long that'll take. Fighting with them over this recall for years is rediculous if they woulda just fixed it the right way I'm sure these issues wouldn't happen. O and also the interior door handles are junk plastic n break n will cause u to be unable to safely exit in a fire!! this recall has takin to long to get fixed n Chrysler should do something about it!!.

After having the n23 recall preformed, the vehicle transfer case refused to go into either neutral or 4 wheel low drive. Dealer reprogrammed the dtcm and tipm and corrected the problem. This was for the original owner. I purchased the vehicle in Feb 2014. After working correctly for several days, the problem reoccurred. It is not safe the have an off road vehicle that cannot be reliably be shifted into 4 wheel low range, which locks the transfer case and provides true 4 wheel drive. As a result, of this safety concern and fiat Chrysler's failure to provide a solution, I have installed a fdcm that has not had the n23 recall performed. This may also be unsafe, but can be mitigated by using the parking brake. Fiat Chrysler needs to provide a real fix to the original problem that does not cause other safety issues.

Vehicle refused to turn over, service 4x4 and engine light on. Brought to dealer replaced fuel pump. Returned to me with service 4x4 and engine light on, slid down on hill no 4 wheel drive. Returned to dealer 4 weeks later transfer case replaced car jump into 4 wheel low while I was on highway almost put me thru windshield. Back at dealer over 1 week the do not know the problem and stated no one on their country wide database has this problem. I was told today that Jeep headquarters wants all reports sent to them to assist repair. I purchased this car used in October and have not driven it more then 1 week. I have a huge payment and huge rental bills I did file a case with Jeep customer but no help.

On two occasions the transfer case has shifted to neutral on it own. One time it left me in the middle of the road with traffic. Also, 4wd low rand of transfer case does not work. There was a recall done, known as the "n23 recall" first, it was done incorrectly resulting in no low range. Second, it was redone correctly and it worked as it should. Now a couple months later it is shifting to neutral on it's own and no 4low. It is a known problem among Jeep owners. The dealers only want to replace parts at customer's cost and very unsuccessfully.
