[XXX] Utility 4D Altitude 4WD 3.6L V6 2020 Jeep Grand Cherokee My 2020 Jeep Grand Cherokee with 3.6L Pentastar V6 engine check engine light came on at 115,000 miles with a P0305 code. The P0305 code for a 3.6L Pentastar V6 engine indicates a misfire in cylinder number five. The week prior I performed a coolant flush and fill with the proper Mopar coolant. A few days later the water pump weep hole started leaking. I replaced the water pump and changed the spark plugs. A few days after this was when the P0305 check engine light came on and I could feel the engine starting to stumble from the misfire. No indication of overheating, coolant temperature was normal between 180 F and 210 F. I kept checking the coolant level and noticed the level dropping after a few days. There was no indication of a coolant leak after replacing the water pump. No coolant in the oil, or oil in the coolant and no white cloud from the exhaust from the coolant leaking into the combustion chamber, typically caused by a blown head gasket, cracked head or block or warped head or block. I set an appointment at the Jeep service department, and they informed me the engine had to be replaced. They said they did a bore scope test and a leak down test to confirmed the coolant was leaking into the cylinder. There are hundreds if not thousands of reports from other owners of Jeep Grand Cherokee and other Jeep, Chrysler, Ram, Dodge owners reporting this same issue. The attached photos show no coolant mixing with the or oil mixing with the coolant, resulting in the coolant only leaking through the combustion chamber to the exhaust confirming the service departments findings.

ELECTRICAL SYSTEM
Dear NHTSA, I am writing to report a serious concern regarding my vehicle’s sunroof drainage system. Recently, a professional repair shop confirmed that the sunroof drain hose had become disconnected behind the firewall. As a result, water leaked into the interior of the vehicle and caused extensive corrosion to major electrical components, including the wiring harness and fuse box located behind the dashboard. The shop provided an estimate of approximately $5,000 to repair the damage, all directly related to water intrusion from this detached hose. At no point was I ever informed—by the manufacturer, dealership, or in the owner’s manual—that the sunroof drain hose required any type of regular maintenance or inspection. This lack of guidance left me completely unaware of any risk of disconnection or the potential for serious water damage as a result. I am also aware that there was a class-action lawsuit a few years ago related to defective sunroof drainage systems in certain vehicle models, which caused similar issues. Given the similarity in symptoms and consequences, I believe this may point to a broader pattern or design flaw that puts other vehicle owners at risk as well. I respectfully ask that NHTSA investigate this matter as a potential safety or design defect. I am happy to provide photos, shop documentation, or additional details upon request. Thank you for your time and consideration. Sincerely, [XXX] [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

First, this Grand Cherokee Trailhawk 4XE is a disaster! It has broken down 4 times so far. And it has been towed to the dealership 3 times. The safety issues is that is has literally stopped in the middle of the road or highway 3 times so far. It has been to shop 4 times to get fixed with no solution at all. I have talked to others who have or had this vehicle with many of the same issues. They hate the car, including m,e, and cannot wait or have gotten rid of the car. Lemon law is my next step. Cannot believe that you have not done a mandatory recall on all of these 4XE Jeeps/.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: WARNINGS
On several occasions, FCW activated unexpectedly in low risk situations (in driveway, pulling into neighborhood) May 2024 & Nov 2024. While driving 60MHP on a 4 lane highway during rush hour on May 19, FCW activated unexpectedly; immediately taking me down to 20MHP. The “BRAKE” warning and beeping remained with the brakes activated for 30-60 seconds. I was unable to accelerate. Vehicles behind me had to swerve to avoid impact. As I was pulling off the highway immediately following, FCW activated again and I was nearly rear-ended. There were no vehicles in front of me for a least a mile during these incidents. Vehicle has been inspected by 3 separate certified Jeep mechanic. All claim they cannot identify an issue with the vehicle as there are no active codes in the system. The dealer has not been able to reproduce the concern. It appears to happen every couple thousand miles. My safety and my family’s safety and other drivers are at risk if this vehicle remains on the road unfixed. The sudden braking could cause a major accident. Jeep refuses to address the issue. The dealer insists nothing is wrong because the issue is not found.

ENGINE
The vehicle (2021 Jeep Grand Cherokee) was on the road for about 90 minutes when the engine shut off for no reason at 65 mph in noon rush hour traffic. We were in the left lane and had to coast through 2 lanes of traffic and an exit approach while trying to avoid a deadly crash with high-speed traffic. There were no warning lights or alarms on in the car. The only message was that we needed to put the car in park to restart. We finally came to stop and waited a minute and restarted the engine and were able to make it home. I called the dealer, and the next appointment was 3 weeks out. I tried driving during a rainy day before the dealer appointment and the vehicle shut off 3 times in 3 blocks, so I returned home and waited for the appointment date. As of today, the dealer says there are no codes and in 2 test rides the car is running just fine. This is a huge safety issue and I hope that we can get help before anything happens again.

SEATS, ELECTRICAL SYSTEM, VISIBILITY/WIPER
The 2018 grand Cherokee has issues with mother board and electrical ghosts. 1st it was headlights and dome lights. they would flicker. i had to change the front lights 2x in a year. i thought this was odd. never did this with any car before. then I was driving home from work during rush hour and it started to rain. started the wipers front and back. the back wiper started and went halfway and got stuck. what happen? the front wipers went on for several revolutions (say 10-20 ) then stopped. started again. then stopped again. the rain intensity grew. Now the -wipers would only work when turned in opposite direction (the manual 1 pass move). this happened as i was trying to get home and stuck bumper to bumper on [XXX] . on this dangerous highway in middle of now a torrential downpour the front wipers now decided it wouldn't work AT ALL. i couldn't see anything and veered off to the shoulder thank god - waiting for rain to stop and then safely proceeded home. the next day the wipers worked. no check engine or anything. this goes on for a week or so with no issue. then out of nowhere the driver seat decides it has a mind of its own and pushes me all the way to the steering column. it wouldn't return when pushing the back button. i had to drive like that for my trip and then it magically went back upon restart. i take to dealer. pump motors bad on front and back. i say not sure your correct and explain. motor changed on front. not fixed. ok we think its the BCM. changed not fixed. finally the PDM was changed and wow it worked. 2 weeks at dealer and this shows that this issue with the control module is certainly risking peoples safety. i hope Jeep does the right thing and prevents a serious catastrophic event. read on the jeep electric issues and my vehicle had a previous "corrected" recall for Electrical Cruise Control. I dont think the fireware updates or software changes fixed all the bugs. be safe out there jeep INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FO

ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS
Randomly, and without warning, the instruments, gauges, and displays will switch into a language I do not speak or understand (Italian). Coinciding with the switch to Italian language, cluster and radio display settings revert back to default settings, auto door locks and paddle shifter becomes inoperative (with no menu to enable), pedestrian emergency brake (peb) lamp or forward collision warning (fcw) lamp turns on with no way to re-enable safety features, units of measurement including speed, temperature, etc. all change, and many other random settings change as well. ***This is clearly a dangerous situation because of all the functions and gauges that change, and the fact it is difficult if not impossible to recover from this due to the language of the setting menus, and the complexity of discovering and navigating through all these changes. I have taken it to the dealer four times. They provide fix that last a week, then say there is nothing they can do and to wait for a possible software update, but none has come and it has been almost a year. When this happens, even if one is able to wade through all the settings menus and change setting back, some items cannot be reset (like the FCA off lamp). According to various Jeep owner forums, some dealers have been able to reset something and temporarily correct the issue, but they charge for this service, and the issue returns randomly again. Here is an example forum discussion, indicating many if not all vehicles are affected: [XXX] Because this is dangerous (for settings/gauges/units to no longer be useful while driving), and it occurs randomly, I strongly believe this issue should be a manufacturer recall. I am available for any needs and have all paperwork from the four Jeep visits. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ELECTRICAL SYSTEM, POWER TRAIN, STEERING
In January work related to recall 95B was performed on the Jeep. The next day the issues started with a warning light indicating the Hybrid System needed service. The Jeep has been in repair for this issue 6 times and over 56 days with no resolution. It is currently in for repair. A buy back request was made but both FCA and the arbitrators indicate it is not a safety concern. There are safety concerns related to the Warning light as it appears to impact electrical communications in the vehicle. Repair notes indicate the communication issues. Also, power steering has stopped working and the engine has died while driving causing a rapid deceleration. Multiple users are reporting the same issues or additional impact related to the Hybrid warning light that started after 95B work.
