The issue I am reporting involves the Active Head Restraint system on my vehicle. I have been victim to the inadvertent deployment of this system not once, not twice, but three times now... In February of 2024 the driver and passenger headrests were replaced under the x88 warranty extension. As far as I know, those were the original headrests that had been replaced after they inadvertently deployed (fortunately, while no one was in the seat). Here we are, only 2.5 years later and one of the NEW headrests has failed in the same way! Once again, we were fortunate that no one was in the vehicle when it happened. My issues are these: -I am a disabled veteran with neck issues, and appear to be driving a vehicle where the head rest is a ticking time bomb. -The faulty headrests were replaced, but apparently with headrests equally faulty. -I can not afford to get rid of my vehicle, I can not in good conscience sell my vehicle at fair market value knowing it is defective, so I am stuck. -The x88 warranty extension is past the 10 years since the original headrests were put in service...but I am now dealing with a 2.5 year old headrest that has failed... -What happens if my headrest deploys while I'm driving down the road..? With my underlying medical issues, what would that do to me? Will it cause me to wreck? Will my loss of control of my vehicle impact another family on the road? WHY WAS A KNOWN FAULTY COMPONENT NOT REPLACED WITH A REENGINEERED COMPONENT THAT REMEDIED THE UNDERLYING ISSUE(S)??? I am requesting the help of all agencies with purview over this issue. Please assist me in achieving a viable remedy, not a temporary coverup bandaid. This is clearly a matter of safety and security for not only myself, but any passengers I may have as well as whatever other vehicles may be on the road around me should operation of my vehicle be impacted by the failure of this faulty "safety" device. Thank you.

Engine knocking or ticking by model year
What owners say
Lifters are ticking. Yet another 3.6L Pentastar engine with the same issue, and no recall issued. Someone is going to die from this defect, if there haven't already been fatalities related to this problem.
The contact's daughter owns a 2015 Jeep Grand Cherokee. The contact stated that there was an abnormal ticking sound coming from the engine. There was no warning light illuminated. The contact notified the dealer and the manufacturer about the failure and was informed that there were no recalls or warranties on the vehicle. The vehicle was not diagnosed or repaired. The failure mileage was approximately 60,000.
Purchased a 2015 jeep grand Cherokee. At around 65k miles vehicle started making a ticking sound. Vehicle was also stalling when accelerating from a stop, usually when making a right turn but also when trying to press gas to gain speed quickly like when entering the highway. There is a known issue with this model where the rocker arm fails and damages the cam shaft. Engine light went on so contacted the dealer and Brought the car in for a recall repair. I drove out of the dealership and the engine light went back on. Brought the jeep back and was told engine issue wasn’t covered under warranty and repairs would cost $5k. I’m contacting the DMV automotive facilities inspector to file a complaint on the dealership and will be contacting a lawyer regarding a class action lawsuit unless I get a resolution to this issue. I drive my 3 small children around every day in this car.
The rocker arm is defected causing ticking noise and Known by manufacturer that it is due to fail but still built car with faulty part. Cost thousands to fix
After an oil change, my jeep starting ticking. I've read of several recalls. My jeep is having all 10 of the recall issues.
I had a warning code of service electronic throttle. It then started to regenerate and we took it to Lithia Jeep to fix EGR recall. They needed to replace engine intake because it caught fire. Several months later the car broke down while driving, sputtering, knocking, squealing. Upon inspection, metal flakes found in oil. Suspected HPFP sucked into engine causing havoc. The HPFP is an open recall but no available replacement parts. I'm currently out of a vehicle. I've contacted Jeep but haven't heard a reply
Loud ticking noise from engine that speeds up upon acceleration. Failing rocker arm causing debris leading to ticking noise. No error codes. Upon personal investigation online, have found "Pentastar Tick" to be a known problem in 2013-2015 Jeep Grand Cherokees on Jeep forums. Problem can lead to misfire while driving, including jerking, damage to cam shaft, as well as engine damage.
Vehicle has 143,345 and engine started ticking from valvetrain on drivers side. It is a known issue with the 3.6 liter V6. Will probably have to pay out of pocket to have rockers, lifters and camshafts replaced.
05/2023 loud ticking noise coming from top right side of engine. Replaced transfer case module. Ticking sound continued. Check engine light code P0523 occurred 06/2023. Known issue with Jeep Grand Cherokee 3.6L: rocker arms and right intake camshaft failure
3.6L Pentastar engine is defective. In October 2020 (55,000 miles), there was a ticking noise coming from engine and reduced engine power. Fields Jeep Dodge Ram Chrysler replaced right intake camshaft and 6 lifters, rockers, and related gaskets. In April 2021, I noticed same ticking noise; brought back to dealership; dealership found "nothing wrong." In March 2022 (70,000 miles) I heard same ticking noise; brought to dealership; insisted something was wrong. SURPRISE! This time, ALL (12) ENGINE lifters/rockers/gaskets & camshafts replaced. Now, May 2023 (80,000 miles) there is, again, ticking in engine/loss of power; this time there is a noticeable bucking and surging when the engine is cold. There were no warning lights or messages on the dashboard to indicate impending engine failure. Symptoms I experienced were loss of engine power, ticking, and bucking/surging. I WISH someone from NHSTA would come and inspect the car. Safety issues can arise if the engine fails while being driven - increased risk of stalling, loss of motive power, obviously collision, any number of things. On two separate occasions, Jeep dealership identified and "fixed" the issue with the same faulty parts that caused the problem in the first place. Other than the dealership, no one else has inspected the vehicle. This issue is ongoing and will continue to occur as a result of an inherently faulty engine design, for which the only remedy is to fix it with the same defective parts.
