Let me preface this by saying, I have spent THOUSANDS of dollars trying to get this fixed. Changed Batteries. Changed Fuel Pump. Changed Sensors. Made sure everything is tight/plugged in properly. It's gone to Jeep and other shops but no one has been able to find or fix the issue. Probably about two years ago this started. I was driving to work as normal and stopped at a red light. When I tried to accelerate, the car kind of jerked a little like it didn't want to go and then chugged on. Leaving work the same day, it did the same thing, but instead of just jerking, the car completely stopped. The dash displayed a notification that said: "Shift to Park". All of the electricity was on (lights, air, dash) but the car somehow switched itself directly into neutral even though I was in drive. Brought it to the shop, and they changed some sensors. A few months later, the same thing happened while in heavy morning traffic. I had to hurriedly put on my hazards because my car was NOT able to move. Tried starting it up after the "Shift to Park" notification displayed and it wouldn't start at all. I turned it off completely, waited a few minutes, tried to turn it on again, missed twice, and on the third try it FINALLY came back on. Every day I drive my car now, I make sure to turn off the Auto-Start/Stop button because this was the one time this happened while it was still on. Brought it to the shop - they had another, TOTALLY DIFFERENT DIAGNOSIS. More recently, I hadn't had a problem in a few months - but leaving work in 4 pm traffic the car felt like it was jerking every time I had to slow down (which was every few minutes since it was traffic time). I finally made it to the on-ramp of the GNO to cross the river and while going around the roundabout, it happened YET AGAIN. It's dangerous. I'm surprised this hasn't led to severe accidents, injuries, or even deaths yet. It's absolutely ridiculous. There are thousands of forums online with people having the same issues. HELP!

I was at a redlight at a complete stop. I began to turn right onto the bypass and got to 13MPH when my Jeep wouldn't catch the next gear. I rode in the emergency lane to make it to an autoparts store. My battery needed replacing so we tried that. I got back in Jeep and went to the red light and began to turn left and when my jeep got to 13MPH again it wouldnt shift to the next gear and I the car behind me had to slam on their brakes to keep from rear-ending me. I have found online a recall for 2016-2017 Jeep Cherokee where over 67,000 were recalled for transmission issues.It took me an hour and a half speaking to 4 different people at Jeep Customer Care whom all told me "well that doesnt apply to your vehicle." How does it NOT apply when my vehicle is doing the exact thing the recall was called for? I would greatly appreciate if someone would contact me about this issue. I enjoy my Jeep but I dont understand how this shouldn't be under the recall when this IS a life threatening situation.

The contact owns a 2017 Jeep Grand Cherokee. The contact stated while driving 20 MPH, the check engine warning illuminated, and there was an abnormal sound coming from the driver-??s side of the engine compartment. The vehicle was taken to an independent mechanic where it was diagnosed that cylinder #3 had misfired and a tune up was needed. The vehicle was repaired but the failure persisted. The vehicle was then taken to a different independent mechanic where it was diagnosed that the cam shaft and both head gaskets needed to be replaced. The vehicle was repaired but while in reverse(R), the vehicle stalled. The vehicle was restarted after three attempts. The vehicle was taken back to the independent mechanic where it was diagnosed that unstated software needed to be updated and reprogrammed. The vehicle was repaired but while stopped at an intersection the vehicle stalled. The vehicle was able to restart after waiting for a while. The vehicle was taken to the same independent mechanic again and was diagnosed and determined that the throttle body needed to be reprogrammed. The vehicle was repaired but the failure persisted. The manufacturer was notified of the failure. The failure mileage was approximately 86,000.

The oil filter housing in the Jeep Grand Cherokee is known to have serious problems and safety concerns. The Pentastar oil filter housing used in these vehicles can crack and warp due to heat exposure and this can lead to serious oil leaks. Despite knowing about this issue, the company has never issued a recall, instead, they have discontinued the production of the Pentastar and redesigned the oil filter housing for newer vehicle models. This oil filter housing is prone to so many issues mainly because it is made from plastic, not a metal that can withstand high engine temperatures. My mechanic is replacing the plastic housing now with an Aluminum one that will withstand the heat and pressure needed to hold up. He told me that it has been a major issue for several years now and he has personally changed several of these out over the years. At one point he said it was such a big issue that he couldn't get parts to repair numerous vehicles that ended up sitting in his lot for a long time until parts become available. Everything I read online suggests that this is a major issue and one that people can't understand why Jeep has not been ordered to recall the wrongly designed housing. The safety issue on this one is potential breakdowns on highways where oil will make roadways slick and cpould also start an oil fire when oil starts to spray on the hot engine. Stranded cars will be parked on the sides of the road posing a risk to them and the other cars on the roads as well I didn't even know about the issue or that mine was failing until I had it in the shop to replace a leaking motor mount. It was during this work that they noticed the issue with the housing and told us that we need to replace it very soon. We decided to change it out and incur another $650 in repairs.

2017 Jeep grand Cherokee, 103k miles. I purchased my car new for around $45,000. All maintenance was done on time. Oil cooler assembly went out, then head gaskets, now I need a new engine. At 103k miles !Jeep has done nothing other than tell me sorry that will be $15,000 to repair. My engine is doing that loud clicking sound everyone is talking about. I-??ve spoken with countless people this has happened to, some as early as 49k miles. There are videos online of mechanics bragging about how much money these engines are making them in repairs. Yet Stellantis still refuses to take responsibility for their 3.6L Pentastar V6 engine issues. Even though there is a current class action against them for it. There are full YouTube videos from mechanics explaining exactly why the 3.6L Pentastar V6 engine fails and still Stellantis chooses to take more money from consumers to fix/replace their faulty engine. Now onto functionality of my vehicle, the start/stop engine problems I see people complaining about on here are real. The first thing I did when I got into my car was turn OFF my start/stop system. 20% of the time my system worked properly when left on. The rest of the time it was dangerous. The car would shut off when hitting the breaks and stall. I would be stuck on the freeway having to restart my car. I-??m lucky it never caused an accident but it is terrifying being in the middle of the street and your car just shutting off and engaging the parking break and stuck in neutral. It-??s happened more times than I can count, stop lights were where my car shut off most commonly. Usually would result in cars honking and people screaming to get out of the way while I scramble to get my car to turn back on. Over all, I-??m so disappointed in this company and how it chooses to treat its consumers.. I was forever a Jeep owner until this week.

My 2017 Jeep Grand Cherokee would not start. The power connection on the starter burned and I could smell smoke emanating from the vehicle. My jeep required a tow to a local garage to be fixed. Upon my Mechanic examining my vehicle, he discovered the engine also had a blown head gasket. To fix these issues is estimated to cost $5k - $6k. My jeep only has 82,000 miles on it.

I have replaced the water pump three times costing me close to $1000. No warning light has came on only the smell when it is leaking that my fiancé recognizes. So in this case do I have to wait until it starts to overheat and I am stranded on the side of the road" Why am I replacing an obvious faulty part? I also know that I am not the only jeep owner within the year of mine that has had this problem that Jeep doesn-??t recognize? If needed I can provide copies of my receipts and dealership paperwork. Also why are the new water pumps protected with a warranty" Each water pump I had installed could have defects.

Issue with transmission/transmission control module. Jeep has a hard time shifting from Reverse, after 3 tries the gear is lost and vehicle must be shut down in order to try again. Once engaged, it'll "BANG" loudly, cause the tires to squeal, and then reverse is granted. Also have an issue going between 3rd and 4th gears. To shift, we have to increase pressure in the transmission, sometimes getting the RPM up to 6k before shifting is allowed. After three unsuccessful attempts, all gears are lost and you have to get down to 33 mph in order to gain 3rd gear back or you have to pull over and restart the vehicle.

While driving on the freeway, in the fast lane, with children in the car the car lost all ability to accelerate, and lights came on. We had to coast to the side of the road and stop the car on the shoulder. We were almost hit while stuck there waiting for a tow truck. Nothing in the car worked, we were lucky to get one car window down as it was 103 degrees. We couldn't get out of the car bc we had two toddlers in car seats and no where safe to go. So we sat there praying and called family to come get us since we couldn't get kids into tow truck. Towed car to jeep and jeep wouldn't even look at it bc they were 3 weeks out diagnosis so we towed to closest mechanic and spent 2k to replace fuel pump. No warning lights messages or symptoms before. 6 months later the car started to shake when turned on and we took it to local mechanic who said I hope you have an extended warranty since jeep has known problems with cylinders and gaskets. We immediately took it to Jeep who said the head cylinders were blown and it was leaking. The car only has 60,000 miles so to have a terrifying situation on the freeway and then issues with the engine was equally scary when it is our family car.

The exhaust manifold bolts cracked on my jeep Grand Cherokee hemi 5.7L which has caused a "tick" sound and my 7yr old can smell gas while inside the vehicle. We have taken to dealerships who refuses to fix under warranty. I called Dodge jeep of Tomball and They say it's not covered emissions. They also say it's common issue with the Hemi's. The problem is only getting worst and causes my son to have headaches. The problem is noticed on startup and acceleration.

I was on the highway and the vehicle shut off. On another incident I was driving the vehicle and the power steering wen out on the vehicle. On another incident after the power steering went out the vehicle put a notice on the dash to put the vehicle in park when the vehicle was already in park. I tried to turn the vehicle off and it would not allow me to do so. Then after repaired multiple times the battery started to over charge to 21 voltage. At this point, the vehicle is just not safe to drive.

Was traveling in the fast lane of highway when the engine just stopped. Able to coast to shoulder of highway. Put car in park and tried to restart the engine. It would not restart. Gas tank was 1/4 full. Had to be towed. The same situation happened in Feb 2020 but the weather was bad and the dealer could not find a problem so it was blamed on the moisture in the electrical system.

I came to a stop at a red light. The vehicle engine turned off and then right back on with out me taking my foot off the brake. Once the light turned green I pressed the gas and the entire car shut off. I didn-??t have any lights for hazards, couldn-??t roll down my windows or unlock the doors. It also wouldn-??t go into park so I had to put on the emergency brake.
