2023 JEEP GRAND CHEROKEE Complaints

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.

My Jeep has been a consistent problem. The vehicle gives many warning and "service powertrain" warnings in the dashboard. Additionally, at the same time as the warnings, the vehicle will lurch - slowing down significantly and making passengers in the vehicle panic. I have gone to the dealer to already fix not 1 but 5, yes FIVE, recalls related to the powertrain system. This last visit (today) I was told that Stellantis acknowledges the issue, but does not have a fix. This vehicle was clearly not ready for production and Stellantis needs to be held accountable to it's customers.

The 2024 Jeep Grand Cherokee 4xe's Automatic Emergency Braking (AEB) system engaging while turning left when there was no car or pedestrian in front of us. This scared us as the car stopped in the middle of a large intersection putting us all in danger of potentially getting hit. The BRAKE message appeared followed by three loud beeps before the car applied full pressure on the breaks and brought the car to a full stop.

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.

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.

The “Service Hybrid Electric Vehicle System” has been coming on intermittently for several months. The vehicle was taken to the dealer and they replaced a wiring harness. That did not fix the issue. The light continues to come on and Jeep technicians have no idea how to fix the issue. Today the light came on and the vehicle stalled and lost propulsion for about 3 seconds and then lurched hard forward as the power returned to the engine. This issue is widespread across social media yet Jeep has done nothing to remedy it. This is a major safety issue, especially with the unexpected lurching forward of the vehicle.

Sometime after performing the B9A recall (NHTSA 23V-787) repair (my vehicle passed), my check engine light came on. Dealer felt there was faulty Airbag ORC sensor and this was replaced. Despite replacement the vehicle continues to throw check engine list with error DTC B273C. We opened a STAR case 6/16/25 and my local dealership kept the Jeep for a week. They stated Stellantis said there was no fix available. Still showing check engine light with B273C error despite replacing sensor.

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.

While driving at approximately 20 - 35 mph, the passenger side rear suspension coil spring fell off. When that happened, the vehicle sank on that side (rear, right side) and the coil spring and spring pad components projected outwards with force towards the road side. No dash lights were activated but, vehicle was exhibiting an unstable (bouncy) driving condition. The vehicle was towed to authorized service center for repairs and a claim was initiated with the manufacturer out of abundance of caution since the event has a resemblance to NHTSA Recall No. 23V-413 (JUN, 2023) and Safety Recall Notice 64A. Said Recall appears on the manufacturer's website as completed for this vehicle.

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.
