Lost 4X4 drive low range. Problem is directly related to the "safety recall N23 / NHTSA 13V-175 reprogram final drive controller module" that a Jeep service center had preformed. I am from North Canada where we have snow from early November to may end it's not safe to travel without functional 4 wheel drive.do we have to wait till someone freezes to death or dies from dehyadration in desert until Chrysler do something.

Jeep has a known problem with the transfer case actuator motor. Last fall, 9-19-13 I brought it in for a recall, number N23. Prior to the recall I had no problems with my Jeep and I had towed it up to Alaska and back, over 7,000 mi. This winter we decided to spend it in Arizona. About 2 months into it is when we get a service message to have our 4WD system looked at and that it wouldn't shift into neutral for towing purposes. So I get on the internet forums and find out that there are thousands of other Jeep owners experiencing the same thing and not shifting into 4 low also. They too had not had any troubles until they had taken their vehicles in for the recall fix which, was a reflash of the transmission software. The transfer case actuator are on backorder from Jeep at one per dealer every 14 days. And I get to shell out $500 for a problem that didn't exist until the recall. Oh, I had towed the Jeep several times since the Alaska trip in 2011. The bigger problem here is that there are a lot of Jeep owners who don't ever take their Jeep's off road or tow it behind something so they don't get the trouble message until they do and they need it. That means there are millions of Jeep owners that don't know they have a problem.

I am not able to shift the transfer case into 4 wheel drive low range or neutral after the safety recall reprogrammed the computer.

While off road very far into the desert of Arizona I was traveling with my permanently disabled wife. We were on desert trails and the trail lead into a soft silt type dry wash. When I tried to put this Jeep into 4X4 low range a message popped up in the interment cluster that said "service 4 wheel drive". the Jeep would not shift to 4X4 low range and lock the differential and drive through the dry wash to safety. This problem is directly related to the "safety recall N23 / NHTSA 13V-175 reprogram final drive controller module" that a Jeep service center had performed. The final drive controller module (fdcm) (N23 / NHTSA 13V-175) re-programming that I had performed at a Jeep service center caused this potentially fatal problem that could have left my wife dead. If we hadn't had water to drink or if it would have started to rain we(she) could have drowned in the wash while being trapped in the Jeep, because I could not place the Jeep in 4X4 low range and lock the differential to drive the Jeep out of a potentially fatal situation.

Went into dealership service center to have "N23" safety recall performed. Before N23 software update there was no problem using the 4WD-low function, afterwards the 4WD-low shift function comes up with "service 4WD" code and will not shift into 4WD-low. I discovered this while stuck in a snow drift this weekend. After researching the issue I discovered that many Jeep owners that went in for the N23 recall are having the same issue.

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.

We are full time rvers and have towed our Jeep about 40,000 miles without any issues, until the recent recall. NHTSA #13V75000, Chrysler N23. The very innocuous recall notice spoke of the dot requiring the recall based on a number of cases where the transfer case shifted into neutral on it's own and the vehicle rolled away, causing damage. The recall went on to say that the fix was to take it to the dealer for a software reprogramming to take care of the issue. The recall notice was very carefully and cleverly written to leave one with the impression that a software issue was the cause of the problem, and Jeep was going to fix it with the reflash of the transmission computer. This is not true. The issue is caused by the failure of hardware in the transfer case, and the "fix" offered by Jeep is nothing more than a band aid to meet the strict letter of the demand by the NHTSA. As thousands of Jeep owners are now learning, after the recall they find themselves in a situation where the transfer case will no longer shift into neutral, or 4WD low, at all. I have personal knowledge of dozens of Jeep owners with these issues who never had a problem before the recall. This problem creates a great uncertainty among owners. We don't know if the 4WD system will work when needed, or end up stuck in neutral or 4WD low, making the vehicle unusable. While not being able to tow may not be a safety issue, I think that disabling a 4WD system that many people rely on in bad terrain or weather would be. I don't think that NHTSA has monitored this situation properly and has allowed Chrysler to commit what amounts to a fraud upon their customers. I think NHTSA needs to take another look at this issue.

Jeep stalled in traffic. Had to quickly shift to neutral and attempt to restart. Has been in the shop probably 7 times for this issue and still hasn't been fixed.

I started to get service 4 wd system light this started after I had taken vehicle in for recall about transfer case neutral problem. I had never had a problem before this had it looked at by certified mechanic. He checked all systems and they checked out ok he cleared error code. A day or so later it returned. He said I should return to dealer. They said it was a bad transfer case range sensor. A deeper look and I found that many people have had this same trouble after having flash update for recall. This part has a large back order ( I was told by dealer part over 500 piece ) and they could only order one every 14 days.

After having my vehicle serviced for the N23 recall, the service 4wheel drive indicator has been coming on and I no longer have 4 low. It is at the service center again for the third time. I am concerned that the recall is either not performed properly or isn't an adequate fix to the transmission issues and is creating I unintended problems.

My vehicle has been maintained by the dealership. I have 56K miles on a 2008 Jeep Grand Cherokee limited hemi 8cylinder I do not do any off roading I am told today that I need an upper differential housing insulator and pinion seals which are leaking. These products should last longer than 56K in miles and are a considerable cost to the consumer for a 5 year old Jeep. There are several bulletins out about this issue but Jeep did not consider helping me because I was out of my 3 year 36,000 mile warranty which is clearly not enough for defective parts. Please see other complaints for a recall issue. Thank you

The contact owns a 2008 Jeep Grand Cherokee. The contact stated that while driving 60 mph, the vehicle stalled without warning. The failure would recur sporadically however, after the vehicle was serviced under NHTSA campaign number: 13V175000 (electrical system, power train) the failure had become permanent. The vehicle was taken back to the dealer where a diagnostic was performed, which did not generate a failure code. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 77,000 and the current mileage was 81,000.

Vehicle shifted into 4WD low by itself while driving in a parking lot. I parked the Jeep in a parking space, and after placing the transmission selector in park, the Jeep started rolling. I had to use the parking brake to keep it from rolling out of the space. The repair shop replaced the transfer case actuator and harness due to the transfer case shifting in and out of 4WD, and having no park, which caused it to roll. I paid to have this repair work done, just prior to Jeep issuing recall N23. Jeep has refused to reimburse me for this repair. On three occasions, I have explained to the reimbursement dept, that my vehicle rolled out of it's parking space and shifted in and out of 4WD and neutral on its own. Chrysler customer assistance refuses to reimburse per the stated language in their own recall. I have sent Chrysler all the required repair documents and receipts.

2008 Jeep Grand Cherokee overland hemi 5.7 stalled after a rapid sudden acceleration. Jeep started "bucking" (losing power and regaining it) then took off without anything touching gas pedal and no warning. The Jeep went from 30 mph to over 50 mph and kept accelerating. I had to throw in neutral to get it to stop. I then pulled over and it stalled out. This has been reported to Chrysler case #[xxx] and I spoke to [xxx]. information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

2008 Jeep Grand Cherokee overland 5.7 hemi stalled on freeway. I had to immediately pull over as heavy traffic and vehicle would not restart and I lost all steering/brakes/engine control. I ended up hitting a road cone (no notable damage) as I was pulling into the somewhat small pullover zone (was in highway construction). Vehicle restarted only after being put in park and removing and reinserting the key.

2008 Jeep Grand Cherokee hemi overland stalled on street twice. Attempting to back into a spot and it stalled twice, blocking a lane of traffic. Had to put in park, pull key out, put key back in to restart. Luckily nobody was driving the posted 35mph speed limit so I was able to get out of the way.

Jeep stalled on the freeway. I was going 65 mph on I-71 and it stalled dead in the roadway. I had to pull over after avoiding other vehicles and restart the vehicle. When it stalled, it gave no warning, simply died on the freeway and I was left with no brakes, no steering and limited drivablity. I called Chrysler and got a person by the name of [xxx] as my case manager. She was the most clueless and incompetent person I have ever spoken with. After taking it to the dealership, it stalled again on the freeway a few days later, same thing at freeway speeds. Chrysler support is a joke...this issue is still going on.

I received in late June a recall notice for my vehicle, titled "safety recall N23/NHTSA 13V-175 reprogram final drive controller module. When I took my vehicle to my local Chrysler Jeep dealer's auto repair shop, they notified me that the issue is software related and they had not yet received the software patch. I took my vehicle again to them in early July, mid July, late July and early August and still they have not yet received the software patch.

Driving at the posted speed limit on a 4 lane divided highway, the 2008 Jeep Grand Cherokee my wife was operating, violently and without warning swerved off the road. My wife described the event as "all the wheels suddenly stopped spinning". the SUV first went off the right shoulder of the road, then skidded across two lanes of traffic and swerved off the left shoulder, nearly rolling over and coming to rest in the median near an embankment. The vehicle was towed to a nearby Jeep dealership where it was subsequently evaluated. The service manager noted that the problem was related to the rear differential. He surmised that the component was assembled "out of spec" and subsequently failed catastrophically. The differential was rebuilt and the vehicle returned. Under the circumstances, my wife will not drive this SUV again.
