2017 JEEP GRAND CHEROKEE Complaints

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.

The component is known to fail on jeep forums weather it fails completely or was not installed properly and may loose its functionality. The event is when towing a trailer and reversing the car will see the trailer as an obstruction and will engage the brakes. The car is alleged to have an automatic system that when towing is supposed to turn the parking assist sensors off to prevent the event occuring. If that system isn't present there is a button that should allow you to turn the parking system off which it does for about two seconds and start backing up the trailer, then it will automatically turn back on and see the trailer and lock the brakes up which is jarring and startling to say the least. I am fairly certain this could cause an accident if it hasn't already.

The contact owns a 2017 Jeep Grand Cherokee. The contact stated that while driving at an undisclosed speed, he heard an abnormal clicking sound emanating from the rear of the vehicle. No warning lights were illuminated. The vehicle was taken to an independent mechanic, who diagnosed a failure with the rear pinion. The vehicle was not repaired. After investigating the failure, the contact related the failure to Customer Satisfaction Notice: T72 (Suspension). The manufacturer was notified of the failure but provided no assistance. The failure mileage was 140,000.

I have replaced the water pump three times costing me close to $1000.00. 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.

The rear differential keeps failing has been replaced 5 times in 3 years. When it fails it causes a lot of the safety features to disable, additionally it greatly affects the stability and handling of the vehicle. When this fails it’s an extremely difficult time driving the jeep and it’s quite dangerous due to the car not being stable.

Bought my Jeep used in Sept 2023. For the first time hooked it up to my small trailer to pick something up. Pulled around and went to reverse and the rear park assist braking jammed on. At first I wasn't concerned. I knew there was a way to turn them off based on my jeep manual. Unfortunately, the park assist would not turn off. Neither the park assist button on dash nor the settings in the computer screen would turn them off. The light on the dash button would turn on for 2 seconds but then turn right back off. In the computer settings , I would click the rear park assist to uncheck it. It would uncheck for a few seconds then check mark would come right back again. I tried to turn off the front park assist in the computer just to see what would happen. I can't turn those off either. This is extremely dangerous. I was very lucky I discovered this before I left my property. What if I was in a busy place, road, parking lot, etc. So I do have an appt with my dealer tomorrow, who claims to have never heard of this issue before. . But after doing simple google searches on the internet, I found numerous instances of many Mopar vehicles, like my Jeep GC, Dodge Durango, Chrysler Pacifica, etc. who have had the same exact issue when they try to tow something and cannot turn off the Park Assist feature to back up with a trailer attached. I also called the FCA US Customer Service line to tell them about this and they said they had never heard of this problem. Yet in the many forums I found where people have posted about this issue, they have had to get software update done on the Park assist module to fix this issue. So it is known, but FCA is not admitting to it being an issue. This should be a recall, or if nothing else, considered a necessary upgrade. Also found you have a report in your system already on this issue and I found a Jeep service bulletin related to this issue as well. I will see what the dealer says tomorrow.

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.

Upon acceleration, the dash lights flicker or fully goes out for a few seconds, passenger side window constantly rolls down on its own, sunroof will not close fully if in an open position, car horn becomes very faint. Had car checked & explanation from the professional to all this, is that it could be the fuse box or alternator. Fuse box has been replaced, yet problem is still occurring. Alternator will be next & hopefully it fixes this problem as it is a hazard especially while carrying children in the vehicle.
