Automatic Transmission Control Module Problems of Jeep Grand Cherokee - part 1

My 2023 Jeep Grand Cherokee has a persistent, intermittent grinding or rumbling noise during moderate acceleration, most often under load such as going uphill. The noise has been documented over seven service visits and confirmed in writing by two separate Jeep dealerships, yet Jeep claims they cannot replicate it consistently. In 2024, my husband experienced violent jerking during upshifts at highway speeds, forcing him to restart the vehicle to restore normal operation. While that specific event has not repeated, the grinding/drivetrain issue continues, with no warning lights or diagnostic codes. The defect has persisted for more than a year, despite extensive service attempts, and raises serious safety concerns — particularly if the drivetrain locks up or loses power while driving. Jeep has not resolved the issue and is attempting to close my case without a fix. Case no. 93653073 is on file with Jeep/stellantis customer care. Dates of service visits: repair history 6/12/24 (1 day) – rhythm Jeep – unable to replicate 6/19–7/23/24 (35 days) – rhythm Jeep – replaced faulty resonator 8/1–8/2/24 (2 days) – rhythm Jeep – replaced exhaust assembly 9/21–10/2/24 (12 days) – rhythm Jeep – pcm update, cam/crank relearn, star case s2309000002; noise confirmed 10/30–11/11/24 (13 days) – rhythm Jeep – replaced motor mounts; vibration noted 11/27–12/17/24 (21 days) – rhythm Jeep – tcm reprogrammed and quick learn 7/12–7/15/25 (4 days) – freeland Jeep – transmission tech assigned; grinding confirmed total days out of service: 88. No warning lights, no stored codes.

On the highway my 2015 Jeep Grand Cherokee diesel briefly stalled and the check engine light came on. I then lost all power and could only maintain a speed of 45mph in a 70mph speed limit highway. I turned on my flashers and could not get off the road due to construction and jersey barriers for several miles. When I had the opportunity I pulled off the side of the road and called to have my vehicle towed to a service facility. I was informed by the mechanic that scanned my car for trouble codes, a p0336-00 was set in my pcm. The mechanic informed me that I would have to take the vehicle to a Jeep Chrysler dealer. This is apparently a known issue with 2014 to 2018 Jeep grad cherokees equipped with the 3. 0l diesel engine including ram 1500s of the same vintage with the same diesel engine installed. The specific problem is that the crank shaft tone wheel is not read by the crankshaft position sensor because of degradation to the tone wheel which is connected to the crankshaft. I have complied with all safety and emission recalls. Related: rc-rw68-20 safety recall w68 transport canada 2020-371 loss of crankshaft position. Requires the replacement of the tone wheel. Issued 02/11/2021. Rc-rw58-20 safety recall w68 transport canada 2020-371 loss of crankshaft position. Requires pcm software update for loss of crankshaft position. In lieu of the tone wheel failing, the computer uses the camshaft position sensor. This is only designed to not disable the car completely but allow the driver to pull of the road. P0335-00 or p0336-00 wil be set and a check engine light will illuminate. My vehicle was not included in the nthsa safety recall and it should have been.

I need help! please! my car is under the x78 extended ecodiesel warranty. The government (epa) sued fca back in 2019 for making these cars with over 14 illegal deletes, like Volkswagen. Instead of making them buy the cars back, they let them say they would make all repairs related to this huge list of components. I’ve had nothing but problems the past almost 2 years. My Jeep was at one dealership a full year. Now it’s at another dealership in ennis texas for about 59 days now. . My Jeep went into limp in mode in front of an 18- wheeler on interstate 45, I was almost killed. I was so afraid! I sent a letter requesting they contact the manufacturer as they have said so on the paperwork. I’ve gone to get my car 4 tiles and it’s still not repaired. I get a text message on Saturday telling me my Jeep is fixed and ready? I’m not getting into that vehicle again, my daughter is having nightmares, she’s asked me please don’t drive that car again! I’ve attempted to pick this car up 4 times, it’s not fixed! same code from 10/04 initial drop off. The same codes came back on 11/9 after they said they’ve replaced the pcm and mass air flow sensor and other parts?.

My jgc 2014. I was on a 5 lane interstate in the far left lane when my car started decelerating at a speed of 64mph. As I was merging into the left emergency lane it switched into neutral gear. I then proceeded to stop and put the Jeep into park and turn it off. Prior to this incident my check engine light had just illuminated a month prior and I ran a diagnostic computer test and it returned stating it was an evap problem. I haven’t had any systems. So I was waiting on my first check to get it taking care of (meaning no gas smell in the cabin, no fuel leaks under vehicle, no bad gas mileage). So the police came to my rescue and helped me pull the emergency neutral pull in the middle console in order to get it off closer to the median so I wouldn’t get hit until I could get a tow. Well it wouldn’t turn over again. It sounded like I had a fuel pump problem but when I went to turn it on but not over I heard my fuel pump cut on. So no problems there! so my battery started running low in voltage so I charged it with a battery pack and it got around 13 v and I unplugged it . It’s a 14 v battery. Well I got my vehicle turned in the off position the emergency neutral gear unlocked and then my windshield wipers started and the car was not on . I heard clicking in the fuse part under the hood so I found that fuse and pulled it. I think took a fuse checker and checked every fuse in my box they all had fire. On my dash it started saying system brake suspension and the check engine light was off. So I checked it with the computer diagnostic tester and it said a code of all u’s which were the ecu and the tcm and the gear shifter which was the only p. O. Code. So we took my gear shift off and cleaned it and hooked it back up. It was nasty. And it would slap again but not show on my dashboard. So I reset my battery and nothing. I am so upset about this. I’ve worked on every vehicle I’ve owned and this is mind boggling. Everything is up to date and seems fine.

Vehicle shifts into neutral when driving down the road and then dies. There is no rhyme or reason to it. Sometimes it does it everyday, sometimes it doesn't do it for 6 days. Seems to happen within 3 to 7 miles of driving the vehicle. Took to Jeep dealer to see if they could figure it out. Over a month later and $1000. 00 Jeep dealer replaced the pcm pin (?) and checked wiring. Picked up the Jeep and 6 days later on way home from work it shifts into neutral going 58 mph down the road and stalls. 30 mins before it would start back up and allow me to drive it. Never any check engine light on, never and noises or chugging, the vehicle does this with no warning and after 5 to 30 minutes will start back up like nothing happened.

The contact owns a 2018 Jeep Grand Cherokee. The contact stated while starting the vehicle the pcm warning light illuminated. The dealer was contacted, and the dealer stated that the vehicle was previously serviced under NHTSA campaign number: 18v332000 (electrical system, vehicle speed control) and that the contact had to pay out of pocket for all future repairs. The manufacturer was contacted but provided no assistance. The failure mileage was 70,000.

I noticed things like the cluster going completely black at random and it would last for seconds before re-illuminating; it happens while driving. I took in my vehicle to the dealership on June 28, 2022, two days prior, I noticed that my doors were unlocking while I was inside my workplace, the alarm was going off another day and I noticed shifting issues with the transmission. On June 27, 2022 I was forced to buy a brand new battery because the Jeep was running in power saving mode, instead of taking a risk with a low battery, I bought a new one and thought everything was good, but it continued to run in power saving mode; I received two cel codes, both correlating to the transmission control module (tcm). Later that evening my son informed me that the cluster light was still on, the Jeep had been parked for several hours so there was no reason for the light to still be on (wake mode?). Also, I notated the codes I received before I had to have the Jeep towed to the dealership on Jun 28th to compare to what the service dept came up with; however on Jun 28th I attempted to jump the battery to take it to the service center but it wouldn’t jump or charge; what happened was, just before the cluster went haywire, the wipers were moving across the windshield while it was in an off position, the uconnect was glitching out then went black, cluster warned to service the electronic abs and the shifter, the fuse box was vibrating and shuddering very loudly, a hissing noise was coming from the back of the vehicle (could be the fuel pump? like compressed air) so by Monday morning, the 27th the battery had completely died and by the time it got to the dealership on tues, I had to use the battery warranty to replace the battery so that the service department could then diagnose the Jeep. Fine, the battery was replaced Jun 30th with a brand new one, but by fri Jun 8th I was told I need another brand new battery. All the issues had had a prior recall and seem to be reoccurring.

Vehicle stalled without warning. No power whatsoever. Illuminated battery light came on. Noticed a burning odor coming from vehicle. Checked engine bay and noticed heavy smoke coming from alternator for a good 10 minutes. Vehicle would not take a jump nor could I put into gear. Battery is completely dead. Pcm also seems to be fried. Will have to be towed to dealership. Called Jeep costumer care and referenced the t36 recall but my VIN does not fall under it even though vehicle fits exact description of recall. Also noticed that many others are have same problem with Jeep and them not expanding the recall to their VIN. How terrible!! this could have easily been a fatal situation. Jeep needs to take some responsibility and action!.

The vehicle had a complete shutdown while being driven. While driving on the highway, several dashboard warning lights began to appear. Within seconds afterwards, the headlights went out, along with the dashboard lights and radio. The vehicle became difficult to steer and then the vehicle lost all power, and could not be restarted. The vehicle was picked up from the dealership the day prior to this occurrence, and the pcm had just been replaced. The vehicle had been towed to the dealership just short of two weeks earlier, after it wouldn't start, having replaced the battery, and experiencing the passenger front window to randomly go down. This incident fortunately did not result in any crash or injury, however, it is only a matter of time if it isn't correctly diagnosed and fixed, as this problem results in an extremely hazardous condition.

The contact owns a 2014 Jeep Grand Cherokee. The contact stated that while the vehicle was stationary, the vehicle stalled without warning. The contact stated that the check engine warning lights was illuminated. The vehicle was towed to a local dealer and it was diagnosed with needing the pcm replaced. The vehicle was not repaired. The manufacturer was informed of the failure and informed the contact that they would cover a portion of the repair cost. The failure mileage was approximately 29,000.

I was driving around 75mph on the interstate for about an hour (not using cruise control) when all of a sudden the accelerator no longer worked. There was no warning, no error lights or codes or anything. I tested the brakes and they still worked. I was able to coast to a stop on the breakdown lane. I waited about 20 seconds and restarted the car and everything worked again. This is my son's car that I was driving and it's really concerning because I thought I bought a safe car for him. I'm an experienced driver, but either way it's extremely dangerous. I looked information up about this issue and I guess it's been happening quite a bit according to the internet. Someone mentioned that the 4 pcm torx head t15 mounting screws that hold the pcm faceplate to the protective metal case where the circuit board is housed are too long. (not the 3 bolts that hold the pcm to the mounting bracket) when there was a vibration or shift, the screws touched the circuit board shorting everything out and causing the engine to stall. The owner put washers with the 4 little t15 screws and were able to fix the problem. I think there needs to be a recall. I'm afraid to drive the car myself or have my son drive it. I'm taking it to the dealer, but I don't think they'll be able to recreate the situation.

The inspection recall on my 1996 Jeep Grand Cherokee did nothing to fix the problem with pcm and catalytic converter specified in the defective issue within the recalls issued. This harms the driver, pedestrians, other passengers and motorists. The tech where I went to have recall work performed ordered parts (see attachment), but nothing was installed on my vehicle. Only "inspected. " the tech was told of detailed poor performance and symptoms of a bad pcm. Such as shifting, stalling, fuel economy & hard to start. The Jeep is not operating optimally & this could mean there are. Other problems between different systems. All of these are indications of a faulty pcm. As well as the abs light being on the dashboard. The pcm is a "critical" system & needs to be replaced. I'm requesting that you fix this problem for free, as it is defective and could mingle with other systems and cause a complete vehicle break down. Or refund the cost to me in full, including labor charges, if I replace/repair myself. If this defective part is not fixed, it could result in property damage, in which cdj would be liable for. Please advise as to how you can help enforce the manufacture to fully repair these defective parts & remedy this problem on fixing the faulty pcm & catalytic converter within a recall and possibly the abs system and transmission. The vehicle stalls on highway, in park, on the street, when stopped and then it stalls out and is hard to start. It also has not been able to go in reverse ( back up). Which mean it's not getting proper lubrication. Also, the alarm goes off when using key to gain access. Unhooking battery to reset does not help.

I continue to have service shifter and check engine issues with my vehicle, which have been ongoing for the last three years. This has occurred while stationary, in motion both on city/neighborhood streets or on the highway. It's happened while turning and in park. When the check engine and service shifter lights come one, in many cases the car goes into limp mode and I lose the ability to accelerate, which causes a severe safety risk if it occurs while turning or going down the highway. Many times my dashboard will go completely black for seconds and my wind shield wipers will turn on. My car has been in the dealership for service related to this issue for 180 days over the past three years and they are unable to resolve the issue. They have replaced the steering control module, the tcm, the telemax communication module, the transmission, and the shifter, but the issue always comes back. Over the last six months the issues have gotten worse and the vehicle is getting more unsafe to drive. Based on my research there are a significant amount of these issues and fca should take action.

The vehicle stalls while driving on the highway. I will be driving on the highway at about 70 mph and sometimes the car will give a jerk when I accelerate and suddenly the vehicle slows down to a stop (gas pedal does not work to accelerate) the car shifts itself from drive to neutral and a message appears on the dash screen "put vehicle into drive". Sometimes the check engine light turns on and sometimes is does not. Once the vehicle has stopped I'm able to restart the car and drive again. This occurs again sometimes multiple times in one day or will happen once every week or so. I was told to change the tcm, battery, spark plugs and clean the fuel injectors and that did not solve the problem. I've been to multiple mechanics and Chrysler dealership service centers and they can never seem to duplicate the problem so they have no real answers as to why this is happening.

The pcm is not communicating between the computer and the transmission. It's making the transmission jump, loose power while driving, warning saying transmission over temp (can come on even when you just start driving), code p1603-pcm internal dual port ram, communication failure. The rpm's have ramped up and down while at a stop, loose power while driving, and can even turn off while driving. Eventually the alternator went bad. Replaced alternator and battery have been replaced 8/16/20. Eventually if the ecm is not replaced then it'll kill the vehicle. The transmission over temp started around 60,000 miles. This issue has steadily gotten worse overtime, became more frequent, and more dangerous. I've read of lots of people have the same issue and there's been no recalls. I feel there should be a recall for safety issues. Please look into the number of people having the same issue.

Pcm has been replacement multiple times by different repair shop. When computer fails it has failed a circuit with 02 sensors which kills engine power randomly while driving on highways. It has turned abs light on and service 4x4 randomly and won’t let the vehicle travel over 10mph. Very dangerous on roads. I’ve had three computers installed in the last year and a half and have given me 3 close calls almost causing accident. That’s 3 too many. I’m not the only one with the computer issues ask around to owners with these Jeeps. How many close called does someone need for Chrysler to not even repair but just to look into. Do people need to die in an accident for people to take this seriously. The issue is not from lack of maintenance either. If my abs module was failed I would no. My vehicle has a 115,000miles on it and when this dangerous intermittent issues occur there are no dtc codes stored. This is a total epic failure done by Chrysler. If they don’t find something soon about theses vehicles. I will be sure never to by another Jeep product. I don’t drive this vehicle unless I’m alone never-mind one of my niece or nephews with me in this death trap I’ve learned my lesson on this one Chrysler please help NHTSA!!.

Current issue - while waiting in a fast food line the battery light came on. . . After receiving food - I pulled into a parking spot and before I could turn the vehicle off, it started giving off error codes related to various electrical items not being available - first warning - svc. Air suspension - second - blind spot detection not available - third evic error - fourth - adaptive cruise not available. . . Then died and smelt like burning rubber when I exited the vehicle. . . A failed effort by roadside service to jump the vehicle did manage to turn on the windshield wipers which wouldn't turn off but that's all that accomplished so I had roadside service put it on a flatbed and tow it to my house since nothing was opened and I didn't want to leave it somewhere with the windows down (of course they wouldn't roll up). . . Pretty clearly this should be part of the t39 alternator recall that was issued due to bad diodes which cause the alternator to fry the electrical components with very little warning. . . The car should die and then the replacement of the alternator should rectify the situation. . . Not - the light comes on - the car immediately dies - and then you need a new pcm or ecm and all new wiring. . . Issue #2 - the suspension has been a total fiasco accumulating $13,000 in dealer assessments not under warranty - the whole system has gone out within 80,000 miles and even after replacing 2 air struts - 2 upper control arms - the tie rods end links - and the cv axles - and the compressor - it still sounds like a rickety bucket of junk. . . When driving - always. Issue #3 - the water pump continuously fails. - not sure if when driving but one would suspect that to be the case.

Vehicle was stationary and idling in the park position, went to shift to reverse and it would automatically shift into neutral and the check engine light came on immediately after. Attempted to shift back into reverse and it would once again shift into neutral. Turned vehicle off and back on and was able to shift into reverse fine however the check engine light remained on. Prior to this event happening there had been a jerking and pulling feeling in the transmission when the vehicle would shift gears as it accelerated on city streets as well as on the highway. Vehicle was taken to the dealership to get inspected and was diagnosed with the tcm codes p1d92 and p1da8. Was adviced to have the valve body replaced or possibly even the transmission. The jerking and pulling feeling is still current.

Tl- the contact owns a 2014 Jeep Grand Cherokee. The contact stated that while attempting to make a left turn when the vehicle suddenly stalled. The contact stated they were able to immediately turn the vehicle back on and continue driving.

The manufacturer was not made aware of the issues. The approximate failure mileage was 140,000. Gl.

Ecm was not functioning properly. Connections were failing. Due to this engine power was lost while running. At times would just shut off. Vehicle was stationary at time of wiggling pcm but don't want to find out if this would happen if I hit a rough spot on the highway going 75. Problem is manufacturer is not producing these computers anymore and can't find one anywhere, also can't be repaired.

"service shifter" warning appears on dash. While driving on city or highway. All lights on shifter are lighted up at one time. Ie. P,r,n,d,s all lite at once. Brought to dealer for pcm update. This did not fix the issue.

While driving the vehicle I receive a message on the info center displaying "transmission over temp" the fan kicks on high and the vehicle will not go faster than 25mph. I have to pull over, turn the vehicle off, wait 30 seconds, turn it back on and it goes away. Had my vehicle at the transmission shop and had it thoroughly looked through and the pcm is to blame. It is very common on these vehicles. I feel it is a saftey concern due to the "transmission over temp" displaying every couple of miles as I drive. Calling Chrysler directly to ask of the problem and they were very rude and hung up on me. Not happy!!.

Tl- the contact owns a 2011 Jeep Grand Cherokee overland. The contact stated that the battery warning light illuminated. The vehicle was taken to an independent mechanic who replaced the battery, the alternator assembly and the pcm. The alternator assembly had been extremely warm internally which had affected the pcm.

A week ago my battery light came on in my car on my way home. Luckily I was able to get home before it died. We drove my car to an independent mechanic that we always go to get it diagnosed. My mechanic said I made it just in time because when they went to start my vehicle it was completely dead. They diagnosed that I had a bad battery and replaced it. They also identified that the alternator was bad and said there was a recall on it (I never received a recall notice on this part though). My car was towed to a nearby Chrysler dealership and they completed all the open recalls on it, including the alternator belt. Then my car was towed back to my independent mechanic. After my mechanic ran my car for 20 minutes the car shut off and it was found that the powertrain control module shorted. I immediately called Chrysler customer service to report the issue. It has been over a week and I have spoken to 5 different customer service agents. Every single one has told me something different and a different process I have to follow. My car has been towed back to the dealership and just sitting there. It has been over a week since I have had my car. I just heard from a customer service agent today that the car has to be diagnosed by the dealership and they have to declare that the pcm is not working. I have no idea what will happen after that. I am really trying to get them to pay for this and not go through a reimbursement process because I don't have faith I will actually get reimbursed in the end. I am so disgusted with the treatment Chrysler has given me. They obviously are trying everything to get out of paying this. Well they picked the wrong person to mess with, I will not back down.

After we purchased the Jeep Grand Cherokee it was taken in for a recall for the tcm, to be serviced and have the power steering fluid checked for leaks due to the well being empty. We were then told when we picked up the vehicle and the power steering well was dry that all Jeeps are like that. After questioning that statement the tech went to vehicle and filled the well. After the dealership replaced the part, the vehicle will hold for 2 to 3 seconds then begin to roll back for 10 to 30 feet depending on the grade of the incline when in drive. It is an automatic with the hill start assist which does hold the brakes for the allotted time. The recall was for the vehicle to go into park if the driver takes off his seatbelt and exits the car in gear. That does work. The Jeep will continue to roll until it jerks itself into neutral then stalls the motor, it will continue to roll if the brake is not applied. Chrysler and the dealership continue to say that all vehicles (automatics) will roll back on an incline in drive and not stop until you apply the brake no matter the distance. We have discussed this issue with multiple Chrysler certified mechanics and they have stated that under any circumstance no automatic transmission should roll back more than a foot. The manager of the service department stated that all vehicles roll back no matter the distance. I stated my kia soul does not even move an inch backwards in drive on an incline, he responded with"yes it does". He then stated that "due to the lemon law we can not guess what is wrong, if we are fix it three times you can return the vehicle and the time we have put into your Jeep we are not getting paid for ". He also stated that our Jeep does not idle high enough and can not be adjusted and Chrysler says we are responsible to have control of the vehicle at all times. We don't want to return the Jeep we want it safe.
