2023 Jeep Grand Cherokee Transmission Problems

Your 2023 Jeep Grand Cherokee has three separate issues: the engine hesitates or struggles when you press the gas pedal, the transmission sometimes shifts out of Reverse into Neutral on its own while backing up (which could cause you to lose control), and water is leaking into the cabin during rain or snow, causing wet floor mats and a moldy smell. The acceleration problem makes it risky to merge or cross traffic safely, while the unintended shift out of Reverse increases the chance of hitting something while backing up. Fixing these issues will likely require the dealer to diagnose the transmission control module or shift solenoid, repair water seals around the power tailgate and door weatherstripping, and possibly reprogram the engine control system.

I am reporting a serious safety issue involving my 2023 Jeep Grand Cherokee hybrid. The vehicle has experienced repeated stalling and loss of propulsion while driving, including in active traffic and in a school pickup line. The vehicle has unexpectedly failed to accelerate or start, creating dangerous situations for myself, my passengers, and surrounding vehicles. The vehicle has stalled in traffic and at low speeds without warning. On multiple occasions, it lost propulsion while driving, requiring me to stop unexpectedly. One incident occurred in a school pickup line, causing traffic disruption and creating a safety risk with children present. In addition, the vehicle is subject to a high-voltage battery safety recall due to fire risk. I have been advised that the vehicle is unsafe to park in a garage, and I am concerned about the risk of fire. At this time, there is no permanent repair available for the recall. Despite reporting these issues and seeking service, the safety defects remain unresolved. The combination of stalling, loss of propulsion, and fire risk makes the vehicle unsafe to operate and unsafe to park. I am requesting that NHTSA review this matter as a safety defect involving loss of power, stalling, and fire risk.

Vehicle was charged to full overnight. Vehicle was warming up in the garage on the charger in EV mode for approx 20 minutes. Vehicle cabin was warm when unplugged and put in reverse. Vehicle struggled to get through minor snow until traction control was turned off even with being set to "snow" mode (excessive slip). Outside temperature was -1 at the time (well above cold weather operating temperature) when EV powertrain immediately ceased. The vehicle then went into a limp mode. After 20 minutes or so the gas engine functioned normally and the vehicle was on the road without any EV power (regenerative braking was restoring additional battery). Stopped at dealership on my way to work to have a DTC code analyzed from when this event occurred and it was TCM-P1D97-00 Incorrect Gear Ration: Clutch A or D Defective. The vehicle has exhibited transmission hiccups and been reported, so this appears to be a symptom of a consistent problem. At some point I recall the vehicle engaging the parking brake automatically, and the shifter demanded I put the vehicle into P to select my gear. It took a brief moment to understand what the car was doing, but I still have no idea WHY it did it. I followed the standard procedures of press brake while in park, push parking break lever/button until it disengages, but it put itself back into park a couple times before finally driving. I turned the vehicle off and on a couple times during this event as that is what Stellantis has said to do when the vehicle isn't fully operable. It was just a weird scenario of me doing the same steps to engage drive while the vehicle went back to parking brake mode until it finally stopped fighting me. The ensuing drive to work seemed normal. I did not hear or feel anything abnormal other than the complete lack of EV power. Thankfully the event occurred in my subdivision where no other cars were impacted by my vehicle's lack of mobility or determination to stop in its tracks.

The vehicle has an active safety recall related to a potential high-voltage battery fire. The recall warns that the battery pack may contain damaged cells that could lead to a vehicle fire under certain conditions. The manufacturer instructs owners not to recharge the battery and to park the vehicle away from buildings or other vehicles due to the fire risk. The defect puts my family and others at risk because the vehicle cannot be safely charged, cannot be parked near structures, and may pose a spontaneous fire hazard. This significantly limits the ability to drive or store the vehicle normally. The issue was present before I purchased the vehicle, and the recall was active at that time. The problem has been confirmed by the manufacturer’s recall documentation. I have contacted dealerships and the manufacturer, but no remedy appointment or software update has been provided, and a replacement high-voltage battery has not been scheduled. Warning messages and restrictions were communicated through the official recall notice. There have been no repairs performed, and the safety risk remains unresolved.

on 10/24/2025 my wife and daughter were in the vehicle driving to her school. My wife was on the phone with me when she stated the car was reving really high and sounded like it was going to blow up how loud it was. she was driving at about 25-30 mph when the car suddenly jerked and shut off completely, the battery light turned on and the check engine light flashed before it shut off. she was able to brake and roll to the side of the road. I had instructed her to keep her foot on the break since it was not letting her shift to park. We stayed on the phone as i contacted jeep directly and get a hold of a rep she said she was able to put it in park and she tried to turn the car on and she was able to turn it on after 10 min. She drove with the hazards on to my daughters school and dropped her off i told her park the car and don't use it until i get home. I got home on 10/26/2025 and the light was off i made an appointment with jeep for that week 10/31 and they stated they were unable to find anything in the computer for the issue that had occurred instead they saw a issue with my heating and it was pump. i have a case open with jeep and they have yet to return my call after a week of non stop calling, i emailed stelantis but they stated they cant assist has to be jeep directly. i would love some help with this as the car has been to the dealership three time for multiple issues and recalls that they stated they did and still show are not done. i have a schduled appointment for the 68c but there is no remedy yet.

73C / NHTSA 25V576 Recall regarding loss of propulsion/vehicles stopping and / or decelerating.

Backing into a parking space in reverse the vehicle all of a sudden begins to accelerate forward with the gear selector showing "R" illuminated almost causing me to hit 2 cars parked in front of me. After putting the vehicle in park and reverse again i was able to park and then the vehicle gave a "service hybrid system" warning and then stalled out. I had no issues prior to this and it seems the 95B recall had something to do with it as I had this performed a week prior. It has a stored code for " digital input crash " according to the dealer but they said it is deemed safe to drive. I don't think so.

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.

The contact owns a 2023 Jeep Grand Cherokee. The contact stated while driving at an undisclosed speed and depressing the accelerator pedal, the vehicle hesitated and stalled. The contact stated several unknown warning lights were illuminated. The contact stated that the transmission failed to shift into the intended gear. Additionally, the contact stated that an unusual alarm had sounded while the vehicle was parked. The vehicle was taken to the dealer, where the failure could not be duplicated. The contact was advised that the vehicle was unsafe to drive and could not be returned to the contact. The contact stated that the failure initially started a day after the vehicle was purchased, and the vehicle was taken to the dealer several times. The contact stated that while the dealer's mechanic was test-driving the vehicle, the mechanic was nearly involved in a crash due to the failure. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure and a case was filed. The contact requested buy-back assistance. The failure mileage was approximately 13,000.

Driving down interstate going 78mph in hybrid mode and the car shuts off and I was able to get over to the side of the road since traffic wasn't bad at the time. Restarted the car and went on my way with no other issues until last week. Driving down the interstate again in hybrid mode and the "service hybrid " light starts flashing and so I changed to all gas for the remainder of the trip. Took it to the dealer yesterday and they had no answers other then they updated the software. We shall see but how it works but I have my doubts that it wont cut off again or have issues. Only has 14K miles on it when this stuff happened.

While driving, the vehicle sends a message that the automatic cruise control has shut down, the car starts slowing down and doesn't respond to pressing on the gas. Only recourse is to move off to the side of the road, shut everything down and turn it back on. The batteries show two miles left on the electric system. This is the second occurrence. Both have occurred at highway speed.

The vehicle is a Jeep Grand Cherokee 4xe plug-in hybrid SUV. While driving in heavy traffic on a 45 mph road, the vehicle suddenly lost propulsion, with the dash lighting up with a large "Service Hybrid System" warning. After several seconds of no response, with traffic trying to work its way around my stalled SUV, the vehicle began to move again, albeit very slowly, just enough to limp it to a side street. After another 30 seconds or so, the problem cleared itself and the vehicle returned to a normal state of propulsion. I took the car to the dealer where I left it for more than a week. Apparently this is a known issue, and a code appeared (B273C-00, Digital Crash Input), but they were not able to replicate the issue while they had the vehicle and so they just reset the code. The automaker is also aware of this problem, but doesn't deem it severe enough to issue a warning to customers or provide alternative transportation while a fix is developed. The dealer's advice is to let them know when it happens again. At this point, I don't feel the vehicle is safe to drive, and it will remain parked until a fix is available.

BELOW IS THE LETTER I SENT TO STELLANTIS. I am writing to file an urgent and formal complaint regarding ongoing, severe safety and functionality issues with my Jeep 4xe , leased through Stellantis Financial. These issues have not only rendered the vehicle unreliable, but they have also endangered my life, the lives of my children, and the public-particularly as I work in an elementary school setting where safety is paramount. Most alarmingly, my Jeep 4xe recently reversed on its own at an accelerated speed without input, and would not stop until I prompted the brakes repeatedly. Had a child or pedestrian been behind the vehicle, the incident could've resulted in severe injury or death. As a parent and educator, this experience was traumatizing and has left me fearful of operating the vehicle in any public or residential space. Additionally, my vehicle frequently enters "turtle mode" (reduced power mode) without warning, significantly increasing my risk of being rear- ended in traffic. This unpredictability is unacceptable for any vehicle-especially one marked as a safe, family-friendly hybrid. These critical safety failures began shortly after the recall involving the vehicle's battery. Since then I've experienced: *Multiple simultaneous sensor malfunctions *Reduced driving speeds and performance *Inability to charge the vehicle on a professionally installed Level 2 charger *Recurring shop visits without permanent resolution While earlier issues were inconvenient, they pale in comparison to the dangerous and erratic behavior of the vehicle now. Despite repeated attempts by service technicians to address these problems, each "fix" is followed by a new or recurring issue. This pattern shows that the vehicle is fundamentally flawed and no longer safe to operate.

Vehicle: 2023 Jeep Grand Cherokee Trailhawk 4xe Problem Description: While driving at highway speeds, the vehicle suddenly loses all propulsion and displays a message stating: “Put in Park Before Restarting.” This happens without warning, creating an immediate safety risk in traffic. The engine shuts down, and I am forced to stop in the middle of the road, shift to park, and manually restart the vehicle. This has occurred multiple times. The dealership and Jeep customer service acknowledges the issue but says no repair is available and has not resolved it. I’ve also been without a reliable vehicle since February 2025. I am aware of NHTSA complaints #11579877 and #11576290 describing identical problems in the same make/model/year. I believe this defect is related to the battery or hybrid powertrain system and poses a serious safety hazard to myself and others. I am also aware of NHTSA Recall 24V720000 related to battery issues, which may be linked to this sudden power loss. Symptoms: •Sudden loss of drive power •“Put in Park to Restart” message •Dash warnings (wrench/lightning bolt/hybrid system fault) •Must restart car to regain function Date problem began: [Feb 2025] Mileage: [17000] Vehicle still unrepaired and unsafe to drive.

3 instances of complete loss of power, 1 while driving. Vehicle came to a hard stop as though I had slammed on the brakes. Dealer and Jeep have acknowledged the problem as a known issue. Jeep is saying it's safe to drive, but dealer agrees it is not and is not returning the vehicle to me. All dash lights came in during each instance and gave the error message "Service Now, Hybrid System Failure." Summary of the 3 instances below. It has been at the dealer since 5/8/2025. 3/29/25 approx 6pm I was stopped, and the error message came on and vehicle shut off. Attempted to restart approximately five times. Let’s sit for a few minutes, vehicle restarted and all error messages went away. 4/23/25 6:30pm Driving at low speed, air Messages came on vehicle abruptly stopped, narrowly avoided, getting rear ended, passengers complaint of neck pain. Engine turned on, all error messages immediately went away. 5/6/25 5:35pm Error messages came on while driving, engine started, no impact to driving. Error messages went away almost immediately. Jeep S.T.A.R. case was created

See attached document for complaint.

On 7/9/24 I was driving on the highway and jeep began to lose power and speed. I was unable to accelerate to maintain speed or safely pull to the shoulder. Jeep completely lost power and stopped in the middle of the highway and I had to wait with hazards until I could successfully turn on the car and drive again. This exact thing happened again today on 7/16/24 it was very dangerous and scary especially since I was almost rear ended.

on/about 3/20 while driving on the freeway changing lanes, the transmission went from 8th gear to 3rd and did so with such violently it felt as though i was struck by another car. The transmission did this multiple times with multiple drivers. This has been a systemic problem since i bought the car with 11 miles on the odometer from a Jeep dealer. last, the transmission stuck in 8th gear and barley rolled into a driveway where it had to be towed to the dealer for not being able to select a gear and with a check engine lite on. This jeep has been at the dealers service shop for over 45 days with issues related to the transmission and only had 3000 miles on the odometer currently. This has been a problem since being purchased. multiple forms talk about transmission issues on their like model 2020-2023 jeep grand cherokees.

While driving on the freeway. Slowing down speed due to traffic, the vehicle through itself in park. With the warning messages stating service transmission. The vehicle would not go into any other gear besides park. Thankfully no collision was caused due to the abrupt halt. The vehicle was then towed for repairs to the dealer. It was determined that the valve body had to be replaced. The transmission now whines when accelerating. Then the forward collision illuminated along with airbag icon. Message stated service airbag system. Airbag system unavailable, safety hazard. Pending diagnosis of why airbag system has failed.

approx one time per month the transmission will not upshfft from 1st gear when accelerating from a stop. Engine RPM is very high and resulting vehicle speed low. Only remedy I have found is to pullover, stop and turn engine off, then restart.

Vehicle emits vibrations and shutter/loud noises from transmission at different speeds traveling on roadway. Dealer has deemed unrepairable and calls it harmonically imbalanced. Vehicle presents hard shifts to gear and downshifts.

When the transmission warms up to operating temp, the first gear shift is extremely rough from a stop. It is most noticeable when accelerating on a highway. It is even worse when utilizing Sport mode. The best way to describe it, is a jerking motion or the transmission failing to shift in time. This is an everyday occurrence and not a random one. My concern is the transmission will fail in the middle of driving on a busy highway. The car has been to the dealer and according to them, this is “normal operation”. It has not been inspected by anyone other than a dealer and no warning lamps are on. This has been an ongoing issue since the date of purchase.

Dashboard showed Transmission Error Message: Service Transmission Continue in D, Do Not Shift or Turn off Engine Until you Reach a Desired Location, You may not be able to shift again until serviced. Vehicle was stuck in 1st gear and would not shift out for 5 minutes. Taken to dealer with engine light on and shown pictures of error messages and dealer found nothing wrong with vehicle. This all happened on a highway and I had to navigate from high speeds to slow and stop in the exit lane.

On 10/07/2023, about 7:30 pm, I was driving down 6th Street in Beaumont California at about 30 mph speed when all of a sudden the engine made a horrible loud noise and it looked like the accelerator pedal was suddenly hit. It seemed that the vehicle speed did not increase accordingly, but my foot had released the gas pedal already. Once I confirmed that the noise was indeed coming from my car, I pulled over and turned off the engine while the loud noise was continuing. Then I restarted the car and the problem didn't reoccur this time. Then, the car has performed normally.

The contact owns a 2023 Jeep Grand Cherokee. The contact stated that occasionally while driving at undisclosed speeds, the vehicle randomly lunged forward and stopped. No warning light was illuminated. The contact stated that he was concerned for his and his family safety while driving. The vehicle was taken to the dealer however, the failure could not be duplicated. The contact was informed by the dealer that the failure was a known issue and was believed to be related to the power train. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 4,700.
