Notes: The 2012 Grand Cherokee hasn’t seen the same complaint volume as the 2011, at least not yet.

It’s worth noting both model years are part of a class-action lawsuit that focuses on a defective TIPM and a long wait for replacement parts.

The 2012 also received national attention after it failed a Sweedish Magazine’s “moose test”. the test measures a vehicle’s ability to swerve out of the way of an obstacle you wouldn’t want to hit while driving down the road … like a moose.

When driving the vehicle within the first 20-45 minutes of starting, the vehicle will stall while driving when slowing down. The vehicle is still at speed but the engine stalls leaving no power steering or brakes. This occurs when slowing typically but can occur at speeds of up to 30-40mph. This happens almost daily at this point and seems to be getting worse.

Issue: Transmission fault leads to unexpected "creep mode" in drive, over-pressurized trans expels trans fluid onto manifold leading to engine fire. Details: When stopped & idling in drive for period of time, transmission goes into creep mode of some sort & when trying to accelerate from stop it does not move. This can happen at a left-turn red-light and when least expected, having disastrous results. Transmission failure from over-pressurization already led to trans fluid being expelled from dipstick tube onto engine manifold resulting in an engine fire. Owner was easily able to replicate the problem by sitting in drive for 7-8 minutes & then attempting to accelerate. Videotaped evidence shows the trans is at normal operating temp, yet tachometer is shooting up to 25,000rpm's & car only creeps forward. At that moment smoke began pouring out from under the vehicle as once again fluid was being expelled onto manifold. Only this time owner did not open the hood so the lack of influx of fresh O2 did not ignite fluid like it did the first time. Vehicle is under 100,000 mile drivetrain warranty & Jeep dealer entered diagnosis and request to "replace transmission, cooler, O2 sensor, & wiring harness" which fca usa, llc rejected. Fca rrefuses to say why. Dealer has held vehicle now for 2months & 2weeks while dealer tries to convince fca to replace defective drivetrain. Fca refuses to supply written documentation of why claim is being rejected. Fca sent out a "special investigator" (for fires) who without meeting the service mgr or authorized drivetrain tech, serve determines it is not under warranty. Yet he knows nothing of transmisisons & spoke to no one at dealer about their diagnosis and issue. Vehicle is unsafe as it will fail to accelerate without notice at anytime & continued exposure to over-pressurized transmission and expelled trans fluid could result in fire.

To whom it may concern: I would like to formally report what I consider a critical flaw with my 2012 9jeep Grand Cherokee equipped with the pentastar V6 engine. I have had multiple instances of unintended acceleration by the engine in the past 45 days. The most recent event resulted in my damaging vehicle's wheel as well as nearly hitting a parked vehicle. I have 85533 miles on my car and this flaw has only manifested itself in the past 3 days (85533miles). I have contacted my local dealer concerning this issue, but have been told that in order to look into this obvious safety defect, I am required to pay for their diagnostic time. I feel that the manufacturer of a product that has such a blatant safety risk should be appreciative of being informed of such a defect, and certainly take responsibility for it. Sincerely, [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

There is a leak at the transmission cooler. Looking on line, this appears to be a common problem. I notices the problem when I tried to accelerate up a hill and the transmission would not shift to the proper gear, and the car slowed and I pulled off to the side of the road to not block traffic. This was dangerous and I was not happy. I turned the car off and on, and it seemed to work fine. The dealer service department located the problem to be the transmission oil cooler leak causing low transmission fluid/oil and making the car not shift properly. I was driving/accelerating up hill at the time. The Jeep dealer at folsom California has the car now.

This is the letter I sent to Chrysler: I'm the owner of a Jeep Grand Cherokee 2012, with VIN [xxx] as I was repairing a flat tire I noticed something very strange and very dangerous happening in my vehicle. I?M a mechanical engineer by trade and in my 60 years of life I have seen and work on a lot of different cars and I know that can happen in situations similar to this. The portion of the visible threads on the front axle came out of the shaft like removing a sleeve and crumbled like bread crumbs what is to say that the portion of the thread engaged with the nut on the shaft (which isn't visible at this stage) won't have the same end results" what can happen to a car driving 65 ml/H on a highway when a front wheel will fall out? is my car just a black sheep? is the lot that my car was produced something out of ordinary" the amount of rust has destroyed the threads on the visible part of the axle. In my opinion this is a disaster waiting to happen. I have purchased extended warranty when I purchased my vehicle and I will be at the dealer tomorrow to repair it I would like Chrysler to evaluate the problem and take the necessary actions to fix the problem preventing life's being lost. As you can see from the photos there are no signs of threads left on the axles. Evaluate better. If you like to send me to one specific representative of your company in my area for evaluation please let me know right way. My contact information will be below. A copy of this letter will be sent to ntsb for the records. I hope that I'm wrong and your experts will evaluate, but I have to do this report to I can have a clear conscience that did what I thought is the best.

My 2012 Jeep Grand Cherokee has the 3.6 liter pentastar V6 with the 5 speed automatic transmission. It has the quadra trac 1 full-time 4X4 system. The transmission is very "clunky" and feels unsure of what it should be doing. Upshifts come early, at low speed and RPM's. often this is not an issue, but sometimes causes the vehicle to feel extremely underpowered. Pressing the accelerator further will eventually result in a downshift and a resulting clunk in the driveline. Low speed driving on curvy roads is not a nice experience with this vehicle. Downshifts are abrupt and anything but smooth. There is often a clunk that can be heard and felt while decelerating for an upcoming curve. The best way to describe the feeling is riding with a person who is learning to drive a manual transmission car for the first time. Not sure if this complaint is recall worthy, but I worry the transmissions indecisiveness is going to prematurely wear the driveline components. Perhaps a software update for the transmission would be a good place to start.

Was driving down highway approx. 65 mph when transmission appeared to jump out of gear, engine rev'ed to approximately 3000 to 4000 RPM's, coasted a distance and the car jumped back into gear and I continued on. The check engine light came on and the eoc signal turned off. This has happened on numerous occasions. The second time the dealer had it for a week+ and rebuilt the transmission. It happen again and they said they fixed it and it did not occur until just last week and it happen twice then. I was preparing to take it back this morning and when I got in the vehicle the check engine light was and it is now running fine. There was a 3 month period that it did not occur and as I said it happen twice last week. I purchased this used with 42500 miles on it, it now has 46500 miles. The dealers hayes Chrysler has done an outstanding job and has been very cooperative, but this is starting to get frustrating. Not sure if this is a safety issue, but likely it is. I have spoke to a couple of owners and they have had very similar stories about this vehicle. Please look into this issue.

3/28/2015 (20,924 miles): This is the second time my 2012 Jeep Grand Cherokee has stalled when I put it in reverse after starting. I started the Jeep and put it in reverse and I began to back out of a parking space and it stalled. However, when I looked at the display showed that the Jeep was in park, however the shift lever was still in reverse, and the radio was still on like the car electronics were on. I moved the shift lever back into park. I pushed the start/stop button but I could not get the vehicle instruments or radio to shut off. I tried several attempts to start the vehicle, however it just clicked once and the starter did not engage. While my foot was on the brake, I put the gear shift in reverse and then back into park. I again tried to push the start/stop button and this time it just kept cranking but failed to start. The vehicle started to roll while the dash displayed P and I was in a level parking lot. When I stepped on the brakes they were hard to press. I used my phone to call moss bros service and they transferred me to the moss motors riverside, ca service center. I explained my situation but all service advisors were busy. I waited on the line for over 11 minutes and someone came back on the line and told me that someone would call me back. See call log from phone records below. I explained to the operator that if I could not get the vehicle to turn off that the battery would eventually go dead. After waiting on hold all this time I attempted to push the start/stop button one more time and this time all controls seem to shut off. I pushed the start/stop button again and the vehicle did start this time. (datetimephone #destinationminutes used / 03/28/157:33 AM855-777-2770toll free call,11.0

I was driving on the 241 toll road up a steep hill going approximately 65 mph and the engine down shifted into a lower gear, the engine began revving high, the RPM went high, and I lost speed. I pulled off to the side of the road. I put the vehicle in park while I called my husband because I did not know what was happening to the vehicle. I wanted to let him know in case I was stranded on the side of the road. We decided we wanted to try to get the vehicle home, if possible. I put the vehicle back in drive and got back on the highway and it did not do it again and I made it home.

My wife was driving the vehicle when all of the sudden the engine started to rev and would not shift up or down. She could only go maybe 20 mph - people passing and honking on a 4 lane road. She found an area and pulled off the road into a retail parking lot. She put the car in park and then shifted back into drive and the issue continued as the car moved but the engine rev'ed without shifting to the next gear. She put the car in park and called the local dealer, where she was told to call Chrysler road side assistance and have it towed in. The dealer took a look at it the next day and could not make it happen again. They said they re chipped it I believe(reset the electronics). This same issue happen again approx. 30 days later and it was towed in and they could not find any issue. They said we had to take the vehicle back and there was nothing they could do. We have had the vehicle towed twice now both in the morning taking our daughter to school. We cannot trust this vehicle and are looking at selling it. That is what the dealer suggested as well.

My 2012 Jeep Grand Cherokee encountered the same problem as stated in the Chrysler recall P54, which is the recall for 2011 Jeep Grand Cherokee. The engine would stall while driving, and it also encountered not start problem as well as the not start on the first attempt problem. Even the car could start, the engine would stall again shortly. The problem is resulted from the faulty tipm, which is the same on both 2011 and 2012 model. However, only the 2011 Grand Cherokee is being recalled. So I urge Chrysler to initiate a recall on the 2012 model as well.
