What 371 owners told NHTSA about the 2023 Jeep Grand Cherokee Srt

When my plug-in hybrid vehicle’s service engine light came on, an authorized Jeep Dealership diagnosed and fixed the electric coolant heater then also performed a software up to address the recall 95B/NHTSA 24V-720. In less than 2 weeks, my vehicle flagged a hybrid system error code “B273C.” The Jeep dealership immediately impounded my vehicle per the regional Stellantis technical team’s orders. My vehicle has been held at the dealership for over a month with no repairs or timeline for when a repair will be available. It’s unacceptable for a custom built fully paid off vehicle (2023 JGC 4xe Summit) to become such a huge liability and poorly reflects on the Jeep/Stellantis brand. There has been no support from their case management team and no urgency/ timeline provided for when this issue will be resolved. When manufacturing defects result in making a vehicle un-driveable, the manufacturer should prioritize finding a solution and provide customers with a rental of equitable quality to ensure the Jeep brand experience is maintained. Most importantly, for a vehicle that is only 2 years old, it is concerning from a safety perspective that it has had so many issues with the hybrid system for which the manufacturer has no solutions 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.

Had 60 miles to empty of gas and slowed down while entering a turn lane. All the electronics flashed a few times, forced the car into park (while moving) and then would not turn on to drive. Music continued to play, car would not turn off or restart, AC stopped working, and was unable to shift into neutral to get out of the road. Was almost hit by multiple cars getting into the turning lane expecting me to drive like everyone in front of me.

I was traveling on the highway at highway speed during peak commuting times when a notice to service hybrid system was displayed on the gauge cluster. The vehicle then lost all acceleration and shut down. I had to safely navigate to the side of the road with zero ability to accelerate or brake in fear of not being able to get off the roadway safely. I was automatically shifted into park once I reached a speed of around 5 mph.

The vehicle has been regularly throwing an error saying Service Hybrid System and having a massive stutter in power while the hybrid motor shuts off and the engine is started to try and take over immediately. The vehicle has been in the shop for this previously, only to be returned to me saying they don’t have a fix for the problem and to continue to drive it. This happened again at highway speed and caused a near immediate loss of 10-15 miles per hour and were it not for evasive driving on my part and the other car, would have caused an accident. This powertrain has major issues that continue to happen.

When accelerating at highway speeds there is a significant power lag when the vehicle switches from between the internal combustion engine (ICE) and the electric motor causing deceleration in the vehicle. This is typically followed by a sudden surge in power causing rapid acceleration. This causes unpredictable speed and makes merging onto highway traffic difficult. When this issue occurs the "Service Hybrid Electric Vehicle System" warning lights illuminates. After several miles, the warning will turn off, but this occurs off and on when changing lanes, merging, or braking in heavy traffic. This typically only occurs at highway speeds when the vehicles transfers between ICE and Electric power frequently and has not been observed at normal city street speeds. The sporadic acceleration performance makes this vehicle dangerous to drive at highway speeds unless the electric motor is turn off. The car has been returned to the dealership numerous times to address this issue as it is still covered under warranty. However, they have informed us that "The code present in the car is currently under investigation by Chrysler. The Chrysler representative told us not to change any parts until Chrysler makes a decision on a potential recall." Despite repeated calls with Stellantis / Jeep customer service who promised us to expedite parts to the dealership for resolution, we are stil left driving this unsafe vehicle. This problem arose within 48 hours of the battery recall maintenance being performed and has been recurring ever since the repair.

We leased a 2023 Jeep Grand Cherokee 4xe in June 2023, and since that time the vehicle has been a chronic source of mechanical and electrical failure. Over the past two years, it has been in for service 11 times, spending more than 115 total days in the shop, with at least 9 repeat issues—largely related to high-voltage interference and hybrid system instability, from our research. The problems began before we ever took possession, with a service record at just 12 miles on the odometer showing a repair to the Integrated Dual Charging Module (1890169A). Since then, we've experienced a cascade of issues affecting sensors, control modules, cameras, switches, and critical vehicle systems—many of which appear to stem from electromagnetic interference (EMI) related to the hybrid platform. Key repairs have included: Park Assist and ADAS control modules (09/28/23) Reprogramming of multiple modules (backup camera, backup sensors) (01/25/24) Backup view camera replacement (02/16/24) Fuel system pump and lighting issues (04/05/24) High-voltage recall 95B, battery coolant pump, wiring harness, battery fire risk & issue (01/30–04/01/25) The final straw came on 05/09/2025, when—while driving 70 mph on the freeway—the vehicle suddenly shut off without warning. We lost all acceleration and power, forcing us to drift to the shoulder in traffic. It took multiple restart attempts and a wait period before the vehicle became responsive again. This was not only terrifying—it was dangerous. The next day, the Jeep dealer where the vehicle was purchased, picked up our car, and we’ve received no update on its status. It is currently undrivable, and we fear it’s unsafe. We previously filed for arbitration for with NCDS (March 2023), which was denied. The situation has deteriorated significantly since then, and we are now filing a second arbitration, alongside this formal NHTSA safety complaint. Certified letters sent to the manufacturer earlier this year have gone unanswered.

My cars dash had a lot of lights turn on and my car just shut off while I was driving I took my car to the dealership and was told that they couldn’t find anything wrong with it. About six weeks later my car just turned off again while I was driving but this time only the service hybrid light turned on and quickly turned off. I just called the dealership and will be dropping off my car again.

On the highway from Chicago to Boston while driving 70 MPH my car had LOST ALL power. I was barely able to get car from left lane to right side of road. Truck almost hit us. We immediately reported incident to our dealership and their response was “we have nothing but problems bring the car in”. We were 300 miles away and they said there was nothing they can do. I restarted car and appeared normal. On way home outside Chicago on Highway at high speed we lost all power AGAIN. Started back up and returned home and called Field dealership in Glenview and Chrysler corporate. We brought Car in and they have had it for week with no solution or phone call.

Monday 4/28, as i was driving at approx. 35-38 mph the vehicle came to an abrupt and hard stop, like someone just pounded on the brakes, the engine ceased running. A large red wrench looking icon and something about the battery flashed very quickly on the screen. After a matter of time (please note this was very frightening,, and am unsure of the elapsed time) the car restarted and I continued very slowly to a corner where I could pull off the road and contact the dealership. At the rate of speed I was traveling I was forcefully slammed into the steering wheel, there were cars behind me and in the adjacent lane. My dog in the rear compartment and in her kennel was also forcefully thrown. This vehicle has had on going battery issues and many others as well. This is not the first report I have filed. Vehicle has been at the dealership for one week, I had to insist upon a loaner which they could not provide. Jeep has a program for a comparable vehicle which they set up and which has not provided a comparable auto. I have had no word from the dealership as to repair and issue found. The ongoing safety issues with this vehicle and it's battery system are totoally unacceptable for me. The jeep has spent 3.5 months from 10/14-mid 01/15 parked due to fire or explosion possibility. It has been in the shop repeatedly for up to two weeks at a time with heating and cooling issues. This latest is just another in a long stream of problems unaddressed proprerly by the Jeep corporation. As the vehicle is still in the shop at the dealership I have no items to download at this time.

Since purchase the vehicle has had a number of electrical issues. From non functioning automatic mirrors, and memory seating, to blacking out infotainment systems to the bigger recalls. Jeep issued a recall notice early October of 2024 for the High Voltage (hybrid) battery. The recall advised customers not to charge the vehicle due to risk of fire. The hybrid feature was the main reason for purchasing this specific vehicle. With my wifes daily commute well withing the batteries capacity we were filling up at the gas station about once a month. Now being unable to charge the vehicle we were filling up more than weekly. This obviously increased the cost of ownership quite a bit. This also greatly decreased the performance of the vehicle as the electric motors provided significantly more power to the underpowered 4 cylinder gas engine. At some point I debated charging the vehicle anyway but being that my home charging area is directly below my [XXX] sons bedroom I ultimately decided against it. Brought the vehicle to the dealer in November of 24 and they refused it as no repair had been released. I tried to stay on top of things, following multiple web forums to have the most up to date information. When I knew that the fix was to be released in the first week of the new year I attempted to get ahead of it and make a service appointment. The dealer would not allow this even though I knew the fix would be available. By the time the “fix” was formally release and I was able to call to make an appointment they were nearly 2 months out from their first available date. After Jeep "fixed" the recall we have been getting intermitent "service hybrid electric vehcle system" warnings on the dash board as well as random losses in power to the engine and or motor. Brought back to dealer where they acknowledged software issue but had no fix available. They determined it was "safe" to dirve and had me take it back.

While idling (vehicle running in electric mode) in park, for approximately 10 minutes we attempted to put the car in drive. The vehicle acted as if it needed to be turned on, displaying the message "Press Brake and Push Button to Start" while also displaying a red battery light. Different warning messages came up showing Traffic Sign Assist Unavailable and others. We could not turn the vehicle off even with holding down the start/stop button, were unable to shift the vehicle either. Finally after ten minutes of pressing the start/stop button the vehicle finally shut off and we were able to restart it with no issues. The next week as I was driving, I would randomly get a warning light with a red wrench and a message that said Service Hybrid System. Both instances have happen two additional times. The vehicle is now sitting at the dealership and they are unable to diagnose the problem. This all has occurred after the 95B recall work was completed. This is a safety issue as the vehicle will not shut off and won't shift. So if the vehicle is parked inside of a garage and idles and then doesn't shut off that will lead to carbon monoxide leaking into the houses. Or being stranded somewhere unable to move your vehicle.

A couple months ago our check engine light came on. Through going to the dealership and a local mechanic we found out that it's an electrical issue as well as a safety issue. The wire connections have failed. This led to the grill shutters being forced open and if they close there will be no air going to the engine which will cause the engine to seize and/or a fire, which would lead to an accident and/or death. This isn't a safety recall at this point and this is a very big concern.

In all previous visits it is documented by the concessionaire that at the time of the test it did not present condition. 5. **Current status (to date):** The problem remains unresolved and we have continued to be without a vehicle every time the unit is taken to the warranty area. The amount of time that the vehicle is in the workshop is indefinite and at no time has we been offered a vehicle similar to a loaner as established by regulations #19 and #21 of the Department of Consumer Affairs (DACO). Despite multiple attempts to solve the problem, the dealer has not repaired the vehicle and the problem continues. This last time we have been without a vehicle for the whole month of September 2024. This represents a chronic anguish for our family, since we depend on our vehicle to be able to work in our accounting business. In addition to all this, this problem with the unit has created an insecurity in us, since at any time it can leave us without service; we have the responsibility to pick up and leave our grandchildr INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Engine Mounts are faulty / victim of design fault. I have had my engine mounts replaced twice within the first 7,000 miles of ownership (at 3,825 miles and again at 6,583 miles). Per my service advisor this is a common issue with all Grand Cherokee models and he anticipates the need to replace them again.

The vehicle will run extremely rough and not accelerate when needed especially after filling the tank with gasoline. It will almost die in the intersection when you’re trying to get past Traffic. It will not reach Highway speed at times and when you step on the gas the engine makes a strange noise and it slows down. The vehicle is very dangerous in this regard. One time I almost had an accident because of it. I have had the vehicle to the Jeep dealership at least six times for this issue and they cannot confirm that it happens on their own and they cannot fix it. I have video evidence of this problem taking place over many months. Chrysler and jeep will not help me. I am concerned about the welfare of the public if they are driving a similar vehicle.

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.

When starting and stopping the engine an awful noise is heard, it sounds like metal is grinding for about 2 seconds. Also on one occasion the electrical system seems to go haywire, as my power lift gate would not work. I tried several things to include turning the vehicle on and off, pressing the lift gate button several times, pressing my clicker, and pressing the lift gate button in the cabin area of the vehicle, to no avail. I finally had to pull the lift gate down, while this was occuring the inside the vehicle on the lift gate lights would turn on and off it was the strangest thing.

I was driving on a major interstate and my car suddenly stopped shifting the gears to allow for faster speed. RPM's were going up to 6 and 7 and the fastest I could go was 30mph. I confirmed my vehicle was only in Drive, and was not in a "sport mode that allows for manua shifting". Was able to safely get off the interstate and pull over, This could have caused a accident. Shut down vehicle and restarted and then performed correctly. Called dealership and they stated they wouldn't be able to get me in for 3 weeks and if the vehicle is now not doing it and issue can not be duplicated there wouldn't be anything they can do.

My vehicle was stopped for several minutes on an upgrade, with stopped cars in front of me due to a traffic jam. I needed to keep pressure on the brake, lest my car roll backwards. After about three minutes, brake pedal lost pressure and my foot went to floor. The engine then went into gear and my car rammed car in front. Engine stalled on impact and was hard to restart. Vehicle currently at Jeep dealer awaiting inspection from Stellantis tech team. This situation reported to their customer care center. No warning lights appeared on dash prior to crash. Indeed, this could have been a more serious accident. I will never trust this vehicle again, and intend to take steps to exit my lease.

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.
