While driving on the highway I received a “SERV 4WD” light and also a traction control unavailable light. Other than that that the car appeared to drive normally other than I could feel the car gears “catching” at starts when I pressed the accelerator. I took the car to the certified dealer and they said it was a transfer case failure and was unsafe to drive as it could have caused the wheels to lock up. This issue is very similar to a recall for other Jeep VINs over the same production timeframe of my Jeep, although my VIN was not included in that recall. I am seeking the immediate inclusion of my VIN into the Jeep recall that exists for manufacturing defects of the transfer case.

Had the ABS Module repaired due to recall last week. Next, I have had 3 instances of the Accelerator sticking when shifting gears and, this never happened before this service.

1. The issue involved the engine and emissions system, specifically a cylinder 3 misfire, accompanied by illumination of the check engine light and white smoke emitted from the exhaust. The vehicle was evaluated by an authorized Jeep dealership, which confirmed the cylinder misfire through diagnostic testing. At that time, per the diagnosis, coil 3 and all spark plugs were exchanged. This did not solve the issue. When picking up the car, check engine light was still illuminated and white smoke emitted from the exhaust. The affected components are in possession of the dealership, unsure if available upon request. 2. The engine misfire and associated white exhaust smoke created a risk of engine performance degradation, including potential loss of power, observed hesitation and stalling, which could impact the ability to safely operate the vehicle in traffic. Additionally, white smoke from the exhaust can impair visibility for surrounding drivers and may indicate an underlying engine condition that could worsen without warning, increasing the risk to the driver and others sharing the roadway. The chemical smell could also nauseate the person operating their vehicle, impeding their awareness and concentration. 3. This issue was proposed by an authorized Jeep dealership, then confirmed by two other mechanics. Dealer diagnostic records document the cylinder 3 misfire and investigation related to the check engine light and exhaust condition. 4. No inspection from manufacturer, police, or insurance representative. 5. Yes, the check engine light illuminated and the vehicle exhibited white smoke from the exhaust which prompted the service visit. Auto-start was not functioning as normal, with an error displayed on screen. Engine would sometimes stall upon start up during cold temperature days. NOTE: vehicle is currently with another mechanic awaiting an engine replacement, will upload that invoice once available.

Front passenger side CV Axle purchased from detroit axle. They confirmed on website it would fit my make, model, and year of vehicle. Once I described that they are selling this part incorrectly and they refused to change website to continue fraud sell I asked for a full refund. They denied and said I'd be deducted shipping costs. If this part would've almost fit I'd have been a risk for life on the road for myself and others. They refuse to fix this safety and fraud violation on their website.

Upon vehicle start-up, the Uconnect screen will freeze up. Placing the vehicle into reverse, the back-up camera is not shown. During the issue, the screen could be frozen/not responsive, or a blue screen. This concern has been an ongoing issue for some time now. It seems to be getting more frequent recently.

Warped cylinder head without engine overheating. Cylinder 4 misfire.

The check engine light keeps coming on. The Jeep repair shop says that it has to do with the flap on the gas tank where you put the gas in. Hence, the repair light keeps coming on so you never know if its real and needs to be addressed or if its the gas tank issue again

1-Rear driver-side Power Lift-gate actuator ball bolt snapped right off while rear gate is open. 2- It came right down on my head and caused severe bump and bleeding from a 250 pound rear door. I am 6ft 1 in, but if it is someone small it can cause sever injuries and possible death from the heavy door coming down on the person. 3-problem was looked at by my mechanic and they cannot fix issue as bolt broke off inside the thread area and no room to remove such bolt. They recommended I take it to a body shop to cut the area out in order to get the broken broke removed. 4-unknown 5- There was no signs of any failures at all.

I Purchased my my vehicle from a dealer approximately two and a half months ago. While driving the transmission of the vehicle gave out. The car rpm shot up to seven thousand and only goes 30 mph. My safety was in jeopardy because the vehicle lowed down rapidly and I had to maneuver to the side of the road in order not to be struck from the rear. I had taken it to get inspected by AAMCO and was informed that the transmission failed.

I have noticed the upper edge on my radio screen appears to the bubbling or separating from itself. It has recently become worse and causes "touches" on the screen. It makes calls and ends calls, switches the screen on and off, changes heating settings, disconnects devices, changes or cancels navigation. It makes it very difficult to drive as I cannot turn the screen off.

I own a 2018 Jeep Grand Cherokee Overland. On December 5, 2025, the vehicle received a transmission fluid exchange service at a Jeep dealership. Prior to this service, the transmission operated normally with no hesitation, harsh shifts, or warning lights. Within a few days after the service, I began noticing delayed engagement and hesitation during shifts. On December 14, 2025, while driving at highway speed, the transmission suddenly shifted harshly with a rapid increase in engine RPM followed by a hard engagement. Later the same day, when stopped at a traffic light, the vehicle hesitated to move forward, revved abnormally, then engaged abruptly. A check engine light illuminated at that time. The vehicle behavior was unpredictable and created a safety concern while driving in traffic, particularly during acceleration from a stop and at highway speeds. The vehicle was driven directly to the servicing dealership and is currently available for inspection. The issue began only after the transmission service was performed. The transmission had no prior symptoms before the service. Warning indicators: Check engine light illuminated on December 14, 2025 after the transmission exhibited harsh shifting and hesitation. Inspection status: The vehicle is currently at the dealership that performed the transmission service for diagnosis.

Transmission line has worn a hole from the location it sits under the jeep. The metal hose now has a flat spot. This is because its rubbing on the metal plate below it. I attached photos. I do have a video of what we are seeing and how it’s happening. Yes, it was taken to a dealership for proper diagnosis. Part is unavailable, because of a common issue. No dealership’s are willing to sell the part. It just stated leaking drives fine for now.

8/2023 one rear seat belt would no longer retract. The problem was reproduced by the service center and they replaced the rear seat belt. 10/2025 the same rear seat belt would no longer retract and 11/2025 the other rear seat belt would no longer retract. Brought into Jeep dealer and they verified there are no obstructions affecting the seat belt and they are no operating as intended. They replaced both rear seat belts in 12/2025.

The car keeps saying the turn signals are out when they all function properly. The car is equipped with the LED factory headlight systems. When it thinks the bulb is out it makes everything flash or turn off so other drivers can’t see your signal. Several other users are also reporting issues online. Dealer says the only way to fix is an entirely new head light assembly at $1300 since the turn signal bulbs are built into the headlight and should be a lifetime part.
