2024 Jeep Grand Cherokee acceleration problems

Filed Nov 5, 2026 · Acceleration · NJ

acceleration capability while driving, particularly at highway speeds. The vehicle becomes unable to accelerate beyond approximately 60 mph, even when I press the accelerator further. The engine does not respond normally to additional accelerator input. The exact cause has not been identified. I suspect an issue involving the powertrain, hybrid propulsion system, or electronic throttle controls, but this has not been confirmed by a technician. Also, I did see on Carvana's website where I purchased the vehicle, that there was a recall for vehicle loss of power - 78C. The vehicle is available for inspection upon request. Plug-In charge also not working/unable to charge. This malfunction creates a potentially dangerous situation while driving on highways. When the vehicle unexpectedly loses the ability to accelerate, I cannot safely increase speed to merge into traffic, pass other vehicles, change lanes, or respond to changing traffic conditions. The problem occurs without warning, leaving me unable to predict when the vehicle will stop responding normally to the accelerator. I have reported the acceleration problem to AXIS Jeep, an authorized Jeep dealership in [XXX]. The dealership kept my vehicle for an extended period but advised that technicians were unable to duplicate the condition or identify any diagnostic trouble codes. As a result, the underlying cause has not been diagnosed or repaired. The vehicle has been inspected by AXIS Jeep, an authorized Jeep dealership. I also opened a case with Jeep/Stellantis Customer Care, case number XXX. The manufacturer has been informed of the recurring acceleration problem and the unsuccessful dealership evaluation. I requested a manufacturer buyback because of the ongoing safety concerns. Stellantis declined that request and offered further diagnostic attempts. There were no dashboard warning lights or error messages before or during the acceleration incidents. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I lease a 2024 Jeep Grand Cherokee 4xe. Since XXX, the vehicle jerks and surges unexpectedly while driving. It happens almost daily, at speeds from 10mph to 30mph, during acceleration. The jerking is abrupt and hard to predict. It affects my control of the vehicle in traffic and when merging, and I am concerned it could cause a rear-end collision. I have taken the vehicle to Salerno Duane Jeep 6 times for this problem: XXX. Each time the dealer recorded "cannot replicate". Repair orders show the vehicle was driven as little as 1 mile during some visits, and one order states a 10-mile road test while the odometer shows 1 mile. The most recent visit began XXX. After 9 days and 20 test miles, the dealer again reported it could not replicate the problem. I have requested they keep the vehicle until it can be replicated. I have recorded multiple videos of the jerking as it happens and gave them to the dealer. During the service on XXX, the vehicle also set fault code P0BBE-00 (hybrid battery pack voltage variation) and required a hybrid battery replacement, with a 5-week wait for parts. The jerking lessened after the repair but has since gotten continually worse. No repair has been made for the jerking. I am asking the federal safety agency to review this complaint for a possible safety defect in the 4xe powertrain or hybrid system. I am linking a shared folder of videos of this happening across multiple months and dates, different times of day, etc. The link is also in a PDF attached to the complaint.

I own a 2024 Jeep Grand Cherokee 4xe that has experienced a recurring safety issue involving unexpected deceleration and loss of acceleration while driving. The vehicle unexpectedly slows down and will not accelerate beyond approximately 60 mph, creating a potentially dangerous situation, particularly on highways when merging, passing, or keeping up with traffic. The vehicle has also displayed a “Service 4WD System” warning. The dealership diagnosed diagnostic trouble code C1463, “Front Axle Disconnect Control – Unexpected Operation,” and recommended replacing the front axle disconnect actuator/motor. The estimated repair cost was approximately $1,054. The dealership subsequently replaced the part, but the same problem occurred again afterward. This indicates that replacing the recommended component did not resolve the underlying issue. During these incidents, the vehicle’s ability to accelerate is severely limited, and turning the vehicle off and restarting it has sometimes restored normal operation. The recurrence of this issue despite the repair raises serious concerns about the vehicle’s reliability and safety. I am concerned that this defect could cause a crash or place the driver and other motorists at risk, especially when the vehicle unexpectedly loses speed in highway traffic. I am requesting that the federal safety agency investigate this recurring loss-of-power and unexpected-deceleration issue in the 2024 Jeep Grand Cherokee 4xe and determine whether other vehicles are experiencing the same problem.

When accelerating, the car suddenly jerks and stops moving at a consistent speed. This happened multiple times over the last 8 months or so. Sometimes it happens immediately after backing out of my driveway. It has also happened while driving on a highway at high speeds (65mph) where I've nearly been involved in high speed accidents. There was a recall back in November that claimed this was a software issue, however, it has continued to happen. No warning lights come on.

While driving down the road on the highway, the hood randomly popped open, engaging the emergency breaking system extremely harshly. Then the vehicle was unable to shift back into gear. Reported problem to dealer and no codes shown for the incident. Jeep (FCA/Stelantis) potentially had the system like Volkswagen when it knows it took it up to the diagnostic system to not show codes were an injury or something serious could’ve happened. Warning indicator lights, and all kinds of indicators were going off in the vehicle at the time of incident, but not the very next day from the dealership plugged it into the system.

While driving in the Los Angelas area on March 24, 2025, on the 210 Freeway approaching the 605 Freeway the vehicle abruptly decelerated from 65mph to 45mph. A message appeared instructing "continue to your destination, do not turn off your engine, if you turn off your engine you may not be able to start it again." We contacted Jeep Connected who directed us to Cerritos CDJR. As we were heading south on the 605 Freeway the vehicle again abruptly decelerated to 28mph. This placed us in a dangerous safety situation as we were at the height of the afternoon traffic. The Service Advisor was able to determine that the Valve Body(VB) and Transmission Control Module(TCM) had failed. Also, both batteries were fully drained of their charge. The mileage was 4095. The comment was that the batteries contributed to the VB/TCM failure. We have continued to experience battery degradation with five (5) batteries having been replaced within the first year of ownership. We continue to identify battery degradation to the dealership but have received no correction to this defect. Over the past four (4) months we have documented "resting" battery voltage at a level where they are at or below 50% of their expected lifetime. While it is suggested that parasitic drain is the cause, we continually ensure that lights, radio, heating and air-conditioning and Jeep Connected are turned off when parked. I have documented to the Utah Division of Consumer Protection and NCDS these conditions. The ruling from NCDS is: DENIED. "I have reached this conclusion for the following reason: the customer did prove by shop work orders a Manufacturer defect does exist with the batteries discharging, which has affected the use and safety of the vehicle. However, there has only been three repair attempts with replacing batteries which is not considered unreasonable in my opinion." With the recognition by an Arbitrator that a manufacture defect exists which affects safety, it cannot be limited to my vehicle.

I just recently purchased my vehicle through Mears Mazda locally in Lubbock, TX. At first i did not notice how unsafe it drove due to the recalls. The more i drive the vehicle i notice it feels like there is a resistance in braking or slowing down and getting stuck in certain gears when i am going at a lower speed below 20 mph. It causes concern for me if i am driving in a bigger city or in a traffic jam as this could possibly cause a major accident if a malfunction occurs with the vehicle causing me to cause a multiple vehicle collision on a highway or street. I did ask the dealership prior to signing " Are there any issues known with this model type of Jeep or recalls?" They simply stated no. I have told them that since i had just recently signed my paperwork Friday and trading in my prior vehicle would it be possible to reverse everything, he stated no. I do not know the laws in Texas or if there is an alternate route i can go about this due to it being a safety issue. When I've contacted Jeep there is yet a remedy to fix this issue.

2024 Jeep Grand Cherokee 4xe — Ongoing Safety Defects With No Available Remedy I am reporting multiple unresolved safety defects on my 2024 Jeep Grand Cherokee 4xe that create a serious and ongoing risk of injury or death. I have contacted Stellantis bi-weekly since May, and my dealership has repeatedly stated they have no available repairs, no recommended remedies, and no ability to take the vehicle in due to outstanding recalls with no fix. I am being forced to operate a vehicle that is not safe to drive. 1. High-Pitch Electrical Hum and Continuous Cooling Fans While Parked/Off When the vehicle is turned off and not plugged in, it continues to emit a high-pitch electrical hum and the cooling fans run almost constantly. This behavior only occurs during charging or thermal management cycles, yet it happens while the vehicle is off, producing an abnormal load and possible electrical malfunction. Dealership confirms the issue but states there is no fix. 2. Instrument Cluster and Infotainment Screens Blacking Out While Driving Both digital displays shut off repeatedly while I am driving — up to 20 times per day. This removes access to critical information such as speed, warning indicators, and hybrid system status. The dealership again states they have no repair guidance from Stellantis and cannot resolve the issue. 3. Air Suspension Malfunctioning Hazardously The air suspension system releases and refills abruptly and uncontrollably. When I start the vehicle, the system rapidly raises and lowers regardless of mode or setting. It cycles continuously even when parked. The dealer acknowledges the behavior but reports no available service procedure or repair bulletin. 4. Sudden Uncommanded Acceleration When Slowing to a Stop (Most Dangerous Issue) When decelerating below ~20 mph, the vehicle will suddenly rev to 4,000–6,000 RPM and lurch forward, requiring immediate and forceful braking to prevent collision. This happens in all modes (Hybrid, Electric, and e-Save). T
