2018 Jeep Cherokee complaints

PTU failure.

Oil leak found on driveway. 2018 Jeep Cherokee Limited taken in for an oil change and diagnosis. Jeep Cherokee has oil leaking into the oil filter housing. Oil filter housing is plastic and needs to be replaced with a metal housing and new gaskets, along with a coolant change and oil change. This appears to be a common failure. Repairs are costly.

# 1 PTU went out and can not get it repaired at the dealer parts not available. # 2 got stuck in snow storm on the way home and had to spent the night in a rural area as four wheel drive stopped working. #3 yes it has been confirmed by a independent Jeep etherized shop and there were no warning lights.

Complete power failure of the vehicle occurred while driving on the highway. Vehicle stalled while in a driving lane, and the driver was not able to recover onto the shoulder. Huge safety risk. After towing vehicle to the mechanic, they confirmed it wasn’t a battery issue (battery just replaced 3 months prior). Appears to be a starter system failure - no warning provided. There have been similar issues from other owners of this make and model.

The component that has failed on my vehicle is the Power Transfer Unit that allows the vehicle to engage in 4 wheel drive. In some instances, I cannot safely navigate without access to my 4 wheel drive. In winter weather, I would be forced to use my Front Wheel Drive only increasing the likelihood of me getting stuck or losing control. I also use the 4 wheel drive on my farm land, and it is essential (part of why I bought it) for navigating the hills and turf safely. The problem was officially confirmed by an official Jeep dealership. No, the manufacturer of the part that failed has not inspected it, but it was inspected and deemed necessary to replace by a licensed Jeep dealership with certified technicians. There was no real warning leading up to the failure. Suddenly, one day, the Service 4 wheel drive light came on, flickered for a couple of days, then stayed on disabling my 4 wheel drive. Worth noting - I have done extensive research on this problem online. It is a very common failure that needs to be addressed or recalled. Jeep actually did do a recall for a portion of the PTU on models through 2017, but I have a 2018 and the problem persists for essentially every jeep cherokee model year since 2018. There are entire message boards online dedicated to this PTU failure issue. It is a very expensive repair to have done.

I was driving and the service 4wheel drive light came on

Service shifter engine light at 20000 miles has done it on and off for two years

My jeep will stall without warning. If i turn, it stalls out, brake it stalls, turn the vehicle on hit the gas to go and step off the gas it stalls. Sometimes it won’t start or it will start then stall out. It’s without warning and has had me left on the side of the road multiple times after pushing it out of the way or trying to get it to start again. I’ve had the computer plugged up to it and even the mechanics said they haven’t seen this before. I’ve had the individual parts to the engine tested, they work just fine such as alternator. I will just randomly lose power while driving. I also have the random Gear Shifter Error that it seems every Jeep owner is going through.

Service shifter light came on and gear shift lights are all red,P,R,N,D. Took it in and they said it was the shifter harness and they changed it. Didn’t have the issue for a while and it started again January & February 2021, September 2022, June 2023, August 2023, and now ever day in 2024. Have to turn off vehicle and restart. Took to dealer and they said that it’s the shifter harness after they already had changed it. Please help, cause when driving, you can’t figure out in what gear it in and you can’t see your speedometer’s speed. Thanks!

I took my jeep in august 2024 to repair a recall (W20) pcm a month later i started experiencing stalling. engine will start fine but after while driving car will stall. almost got hit from behind one of the times. car will stall in traffic and no restart itself sometimes. other times it quickly restarts and feels fine. i got an oil change today. but stil having the issue.

Vehicle keeps having the service shifter light come on with all of the "PRDN" lights turning red. I have to quickly try and get off of the road and see if I can get my car into "Park" and then turn the car off, let it sit for a few minutes and then turn the car back on. There is not a recall on this, but I can see that a lot of people with this same type of vehicle and same year have had this issue. The shifter wiring is faulty and also needs updates or else this can cause the vehicle to completely turn off while driving which could in turn cause an accident.

SVC 4WD warning. Diagnosed at Jeep Dealership (Recommend replace due to CODE C14A7-97 - PTU Motor-Component or System Operation Obstructed or Blocked. Part is on a back-order status, the only information provided from the manufacturer is they are working to obtain part status. We have no ETA on part at this time.) Part is not available, and car can't be driven

Error popped up on the dash saying Service Shifter, all the lights on the gears lit up. First occurrence, I was able to turn the car off and the error went away. 1 week later, it came back and has not gone away. Was unable to put car into drive.

Randomly and more often occurring, I turn on my vehicle and it tells me "service shifter" and all of the lights on the shifter turn red. I can restart the vehicle and it may or may not come back. This happened to me when I first bought the vehicle and they told me that they could not get the message to come up. Oddly enough, the message did not come up for years until just recently it has been happening again. My center console screen between my speedometer and my odometer just says "service shifter".

The contact owns a 2018 Jeep Cherokee. The contact stated that on several occasions while driving at various speeds, or while parking, the gear selector was depressed and all the gears were highlighted on the selector, making it unclear what gear was selected. The contact also stated that the "Service Shifter" message was displayed. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was approximately 52,000.

Service shifter alert

The contact owns a 2018 Jeep Cherokee. The contact stated while driving approximately 45 MPH, the vehicle lost motive power with the service shifter warning light illuminated. The vehicle was steered to the side of the road and turned off. The vehicle was restarted, and the service shifter warning light disappeared. In addition, the contact stated that the dealer could not diagnose the failure; however, the navigation system was not working correctly, and requested that the driver drive through a body of water. The contact also confirmed that the navigation system was providing incorrect information. The failure reoccurred. The failure mileage was approximately 12,000.

SVC 4WD light and clunking noises code C14A7-97-Rear differential and ptu spline failure and replaced at 34,870 miles. Now 71,060 miles SVC 4WD light on and code is again C14A7 rear differential and spline failure. And was told this time the 48 month warranty on the parts has expired. Its been 52 months. I purchased this 2018 in 2017. Why is this not recalled like the 2017 for the ptu and differential?

The brakes are locked up and will not disengage one week after coming home from the store in the rain. I was lucky enough to have it parked in my garage when I found out. I had a mobile mechanic look it over and I was told that the electronic brake control module needs to be replaced. The vehicle only has a little over 8,000 miles on it so far. I attached a picture of the part and a screenshot of the email stating what has to be done to repair the problem.

Car made a noise and the service 4wd came on. The shop I went to told me it was PTU and that when he called Jeep they told him it should’ve been a recall with how many they do daily. My Jeep is well maintained and is a 2018. Jeep should be at fault to fix this

A week ago, I went to my local garage that I trust for a completely different reason than I ended up leaving with. I have a 2018 Jeep Cherokee. I have less than 62,500 miles on this vehicle. I do not tow anything. I do not go off road. I do not ride down trails or do anything out of the ordinary. I live in the Boston area. What I found when I was at the garage was an issue that the garage couldn't fix. I needed a rear differential unit replace. Jeep discontinued the Jeep Cherokee this year. What a coincidence because the differential unit isn't available. It's been on back order all year based on what I see online. I spoke to someone at a service department today. He told me it has been on back order, there are 150 ish that have been requested. There are 8 ready for deployment in July. So I will have 140+ people ahead of me for this thing that doesn't exist on a vehicle they no longer make. Today I went to a Jeep dealership and they looked at the unit and said at some point it's going to break and I'll lose control of my vehicle. They've seen this issue in the past and its not pretty and told me I should trade it in immediately. I have a vehicle with 62,500 miles that is essentially totaled . It will become inoperable in a matter of months, if not weeks. Even if they get the part, they told me it would be $3,500 for the part, plus another $1,500 for labor, plus likely the axle needs to be replaced, plus another part and it's likely $8,000 to fix it all. And it could be 6-12 m

Approximately 3 weeks ago had SVC 4WD light came on. I took it to my mechanic and was told they couldn't diagnose it because a special subscription has to be paid for to access what the Jeep code is. Was able to find a mechanic that could diagnose the Jeep code, turns out the PTU needs to be replaced at an estimate of $5,000. In researching it appears many others have this same problem and is a safety problem for those driving the car. Of course, part is back ordered so that indicates this is a major problem with Jeep.

I keep getting an warning that my shifter needs to serviced. After much research, I've discovered that this is a known and common problem with Jeep Cherokees. It should absolutely be a safety recall and fixed at no cost to the customers.

The vehicle consume too much oil .it completely run out of oil after driving a 1000 mile only .the engine stop suddenly while driving which put my safety in danger .because it happened when the vehicle engine stop running in the highway in the middle of traffic. I call the manufacturer they said there is a recall (W20 )for this car regarding those issue . And they said once they update the car software those issues should be resolved. But afterwards the same issue still happenings. The car currently only has 32k miles .those problems started back on March 2024 when.the car has only 24k miles

The contact owns a 2018 Jeep Cherokee. The contact stated that while the vehicle was in park(P), the electric parking brake engaged independently. The contact was unable to release the parking brake. The contact contacted an independent mechanic who informed her husband how to release the parking brake. The vehicle was taken to the mechanic where it was diagnosed that the failure was due to water damage. The vehicle was repaired. The dealer was contacted and confirmed that the VIN was not covered under recall for the failure. The contact stated that approximately 10 days later the failure reoccurred. The vehicle was returned to the independent mechanic who confirmed that there was water corrosion causing the failure. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was 50,000.

Vehicle started to make “knocking” noises from front axle when going over bumps. Brought to a shop that stated the ball joints just needed to be greased up. The sound returned within 24 hours and become continuous while driving. The car begins to shake and feel unstable at speeds above 45/50mph. Brought vehicle in that day to a new shop, which diagnosed the problem as a faulty/broken Power Transfer Unit (aka transfer case). They advised that this piece was under a safety recall for my make and model. Upon contacting a local dealership, they informed me that the safety recall does not apply to my specific VIN, and that the part is on national back order. The second shop advised that I can still drive the car with the broken part, however I believe the car may pose a safety risk in its present form- especially considering the part in question is under safety recall for my make and model

The contact owns a 2018 Jeep Cherokee. The contact stated that while operating the vehicle, there was a chemical odor inside the cabin of the vehicle. The vehicle was taken to the local mechanic who diagnosed that the front passenger’s side half-shaft assembly was faulty and needed to be replaced. The vehicle was not yet repaired.

Doing some investigation into this vehicle, it revealed that the current design of the rear compartment does not provide adequate protection against water intrusion. There are several points of entry through which water can seep into the electronic components, including the improperly sealed connector to the EPB. Furthermore, similar incidents involving the same make, model, and manufacturing year indicated that this is not an isolated problem. Numerous reports from owners of 2018 Jeep Cherokee have surfaced, describing similar cases of water damage leading to the malfunction of the electronic emergency brake. This suggests that there is a systemic manufacturing defect that needs to be urgently addressed. The implications of these malfunctions are significant. Not only does this defect render the vehicle immobile, but it also poses a serious safety risk to the driver and other road users. In both the March 2023 and June 2024 incidents, the affected vehicles were stranded in traffic, creating a potential hazard and increasing the likelihood of accidents. It is evident that this issue has the potential to cause harm and must be addressed without delay. Given the recurring nature of this problem and the severity of its consequences, immediate action is imperative. It is crucial that the manufacturing company identify and implement a solution that effectively prevents intrusion into the rear compartment by implementing alternative waterproofing measures. Additionally, it is essen

This car has been in the shop multiple times for engine and transmission problems. Had a new transmission installed at 19000 miles. Now at 30000 the transmission has failed again. Car has multiple TPM, ABS, and power train issues that Jeep cannot correct.

2018 Jeep Cherokee Limited, 154k miles currently. Purchased vehicle from third party with under 100k miles. Vehicle maintenance was always done per manufacturer suggestions(from third party and myself), at 152k miles I noticed vehicle overheating when driving 25-55MPH (with AC off). Also noticed a reduction in the powertrain. Vehicle diagnostic done at local mechanic and cleared(no coolant leak, no oil leak engine was in good condition.) Oil change and other regular maintenance work done as well. Then engine eventually blew a gasket, and a hose resulting in me having to replace entire engine and other damaged components due to the engine being poorly built.

Jeep Cherokee 2018 limited AC turns off throughout the drive. It makes the SUV vibrate to the point I can’t see out the review mirror. Had AC serviced and checked. Issue persisted shortly after.

SRV 4WD. Warning lamps. PTU internal failure. Other 2018 Jeep Cherokee on recall. Driving down highway at speed 75. 4 people in car. Disengaged gear. Almost hit an 18 wheeler. Death for sure.

[XXX] noticed parking brake was engaged and (P!) warning light was on, I had not turned parking brake on. I pushed brake pedal and parking brake to disengage. Next day it was on again when I started car. I went to repair shop and they added brake fluid, the warning light stayed on. When home I went to repair shop Wednesday [XXX] but when they checked it hours later the light was off and brake fluid was full so we thought the warning light reset. Next day while driving warning chime sounded and (P!) Warning Light came back on and stayed on. Friday [XXX] took it back to repair shop and they said had to take car to a Jeep dealer. Monday [XXX] made appointment and took car for hand car wash, after the wash the Red BRAKE light was flashing and the mileage was also flashing. Did not drive until my appointment on [XXX] Marino Jeep, in Chicago. Marino Jeep called me stating water leaked into control module and caused corrosion to the brake system. I will have an invoice in a week after parts come in to complete the repair. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I went in to my dealership Nov. 24,2023 for a water leak to the driver side floor and to the back seat behind the driver side. It was starting to smell so I used some carpet cleaner to get rid of the smell. They replaced the panel cowl side trims on both sides of the windshield. I told them that only driver side floor and back seat behind the driver was wet. Never said that there was a water on the passenger side floor? Charged me $543.22. Had to go back a second time because it was still leaking on Dec. 20,2023. This time they put caulking to solve the problem at no charge. Now April 19,2024 I still noticed that it's leaking after I washed my vehicle. So now I have to go in a third time in less than 6 months. Never solved my water leak after paying them $543.22. I do believe that this water leak was happening possibly since day 1 having the vehicle. I bought weathertech floor mats once I purchased my vehicle. I had a liner on the floor and then the floor mat on top. So its like using 2 mats. Never thought to look underneath my mats for a water leak. I do not want this problem to persist and possibly have black mold in my vehicle. Already contacted Jeep customer service if they can help resolve this issue and If they can provide me with a rental car for my inconvenience. They did provide me a case number. Still waiting for their response. Please let me know if you need more information. Thank you.

Fuel flooding engine and ruining catalytic converter

I keep getting a “service shifter” message and all gears light up red. This has now happened about 15 times. I asked a dealership about it, but they said they would have to correct all of the wiring. I saw that many other jeep cherokee owners also experience this same issue and it does not go away.

The shift lever lights are all illuminated red, the shift Service message appears on the dashboard, the error appears and disappears.

Every now & then the menu will pop up & say service shifter & won't allow you to exit that notification & all the lights on the shifter turn red at the same time. The only way to reset it is to turn the jeep off & back on again. I've gone a couple months now without it happening but for awhile it was doing it almost every day. It doesn't seem to affect the driving at all though which is odd. However there has been a pretty consistent jerking when accelerating into higher gears. Not sure if it's related or not. My dealership said there was nothing wrong with my vehicle so i just keep dealing with it.

The car was showing a service 4wd alert which the dealer said the PTU needs to be replaced.

The rear differential has failed on my Jeep after 42,000 miles. I tow this this vehicle behind a motorhome and it could have locked up or thrown parts and differential oil on the highway. It would be worse if it exploded while driving at highway speeds. It was replaced but failed again after only 900 miles. There are no parts available, Jeep has also changed suppliers, again with no parts available. It is now nearly April, with no ETA for a replacement part. There should be a recall on this part, as there are multiple incidents of similar failures on various Jeep websites. I paid $1,000 to Jeep out of pocket, as my powertrain warranty was 4 months past expiration. I contacted NHTSA in January about this and have not received a response as of yet.

See attached document for complaint

All lights on shifter light up red (P, R, N, D) and an error message of "SERVICE SHIFTER." Come to find a lot of people are having this same issue.

Vehicle is driving as usual with no odors or sounds. 4wd unavailable light came on. The code for this states PTU is bad and must be replaced. Dealer quote is $5270 to replace. Apparently there was a recall on these for my car just not my year. Obviously there is a huge issue with this part. This vehicle is well maintained. There should be a warranty to cover this or the very least we should get a reimbursement. Please look into this. Also read the keep forums as this is a common issue. I thought keep was supposed to be a hearty vehicle. Very disappointed. I will be happy to provide receipt once I get my car back from dealer

My 2018 Jeep Cherokee with 88K miles on it. I heard a loud popping sound, and my car was jerking. Took it into the dealership for maintenance and I need to replace the rear diff and axle shaft. This could have locked up worse and caused an accident. I see that there are more complaints about this same problem.

At exactly 37000 miles my service “shifter light” comes on every 4-5 days. I’ve noticed in the warmer months it comes on more frequently. During the cold winter it came on twice. It’s becoming warmer again and it’s popping up often. My husband has a 2017 jeep Cherokee with the same exact issue. Our dealership gave us no answer to this problem. Not sure why, i just hope this doesn’t cause a major issue or hopefully a recall soon to fix this!

2018 Jeep Cherokee The power transfer unit malfunctioned and had to be replaced. A warning light indicated that there was an issue. It cost more than $5000 and the part was on back-order for 2 months. The dealer explained that they had so many power transfer unit replacements they could not repair my car unit the back-ordered part arrived. I also paid $2000 or more in rental car fees during that time. This all occurred only a few months after the manufacturer's warranty had expired. The repair was completed at the dealer. I am filing this complaint because Jeep Cherokees from 2017 had a recall for power transfer units. My car was built in 2017. I believe the power transfer units in some of the 2018 Jeep Cherokees are also faulty. There are many, many posts online regarding this issue. I appreciate that you are able to look into this.
