2018 Jeep Grand Cherokee Complaints

system works intermittently--sometimes won't engage--other times suddenly cuts off when engaged

In approximately early to mid-August 2026, I was driving my 2018 Jeep Grand Cherokee at approximately 40 mph when the passenger-side Active Head Restraint (AHR) suddenly deployed without any collision, rear impact, or other event that should have caused it to deploy. There was no passenger in the seat at the time, so fortunately no one was struck or injured. The vehicle had approximately 55,179 miles at the time of the incident. Its current mileage is 55,279 miles. Following the unexpected deployment, the passenger-side head restraint developed a persistent rattling condition. I brought the vehicle to Naples Chrysler Dodge Jeep Ram for inspection. The dealer advised that the head restraint would need to be replaced and provided an estimate of approximately $1,001.95, including parts and labor. I subsequently contacted Jeep Customer Care regarding the problem. My case was assigned Case Number 97938645 and was initially characterized as a high-priority Repair Cost Assistance matter. I...

Subject: 2018 Jeep Grand Cherokee – Sudden Loss of Power, PCM Failure, Electrical Failures, and Concern Regarding Recall-Related Symptoms I am filing this complaint because my 2018 Jeep Grand Cherokee experienced a sudden and unexpected loss of power while I was driving, and I am very concerned about the safety implications and the possible connection to the recall-related electrical problems associated with this vehicle. Before the final failure, my Jeep had been experiencing electrical and starting problems. The alternator failed, the batteries went bad, and I had already paid for multiple diagnostics and repairs. At the time, we did not understand that these problems could potentially be leading to or connected with a PCM failure. I have spent approximately $800 on diagnostics and parts trying to determine and repair the cause of these issues. The most serious incident occurred when I was driving near a school and approaching a stop sign. The Jeep suddenly began losing power and...

I am reporting repeated drivetrain and transmission failures involving my 2018 Jeep Grand Cherokee SRT. The problems began with failure of the driveshaft carrier bearing, which was replaced with a brand-new component by an independent mechanic. The transfer case subsequently required replacement and was replaced with a brand-new unit by a reputable dealership. After these repairs, the original transmission mechanically failed at approximately 99,000 miles. I replaced it with a transmission from a 2021 model that had approximately 45,000 miles. That transmission then failed after only approximately 5,000 miles of use in my vehicle. I am now having another transmission installed, meaning my Jeep is receiving its third transmission. By the completion of these repairs, I will have spent more than $20,000 addressing drivetrain and transmission failures. I am concerned that an underlying drivetrain, transmission, electronic/control, or other vehicle-related condition may be contributing...

I own a 2018 Jeep Grand Cherokee Limited. The driver's-side Active Head Restraint (AHR) suddenly deployed/opened without the vehicle being involved in a collision or rear impact. The head restraint separated/opened with significant force and will not remain in its normal position. I am not aware of any warning lights, warning messages, or other symptoms before the head restraint deployed. This creates a serious safety concern because the Active Head Restraint is positioned directly behind the driver's head and neck. An unexpected deployment while the vehicle is occupied or being driven could cause injury to the driver's head or neck and could also startle or distract the driver. The vehicle has not been involved in an accident that would have caused the Active Head Restraint to deploy. The failed head restraint/component is available for inspection. After researching the failure, I discovered that FCA/Stellantis has previously issued technical service and warranty information concer...
