2015 JEEP GRAND CHEROKEE Engine Problems

Car accelerated without warning propelling me across a curb, street, then a second curb. The SUV was stopped upon impact at a concrete building. Fortunately there was no injury to others but the accident caused the car to be totalled by my insurance company. There were no warning lamps, messages or other symptoms of the problem prior to the failure. The airbags did not deploy upon impact,

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.

While driving vehicle shuts off unexpectedly, with steering wheel losing power steering. It will then have trouble starting again. Turning on and off by itself. It will then work just fine after 15-20 minutes.. It has been doing this every few months for a couple years now. I have taken to dealer a couple times, and they have had me change battery initially. But can’t give me a reason why it keep happening after that. Most recently, once I was able to work again after it had shit off on me while driving, it would then not shut off. I could not turn the car off. I took to dealer, and eventually it turned off. It is at dealer currently at time of this writing.

We were driving and we heard a chime and nothing showed on the display panel. Then we went thru the displays and saw a message regarding the ACC something about manual something. Then we lost power. Since we were on the highway We turned the truck off and started it again to potentially reset. We drove a couple blocks to exit the highway and lost power again. The we got out of the vehicle and smelled smoke. We peaked under the hood and saw fire. We all got out, grabbed our stuff and then the fire spread and engulfed the truck. Total loss.

The contact owns a 2015 Jeep Grand Cherokee. The contact received notification of NHTSA Campaign Number: 22V406000 (Fuel System, Diesel) however, the part to do the recall repair was not yet available. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. Additionally, the contact stated that the check engine warning light was illuminated. The manufacturer was made aware of the issue. The failure mileage was unknown. VIN tool confirms parts not available.

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 oil cooler is leaking and shooting oil around the engine compartment making a lot of smoke. Not sure if there was fire or not. I went to the 2 repair shops and both said that they are inundated with the same problem from jeep owners and the parts are very expensive and hard to get. I was told not to drive the car because it could cause a fire, and I cannot afford the repair. The Chrysler corporation should take responsibility. This is a major safety issue, and now I am stuck with a vehicle that is too dangerous to drive.

On April 24, 2023, while driving 53 mph down a busy highway the car just lost all power. I wasn’t able to control the vehicle then I stepped on the brakes but only if the back brakes worked. Which caused the vehicle to spin out of control until I eventually flipped the vehicle upside down into a ditch. It was one of the scariest things I’ve ever experienced. Besides the fact my drivers side head rest and seat bell we’re also broken at the time. I was going to the dealership on April 26th to have both the headrest and seat belt fixed. It’s also the second time the car lost power. In addition to that my headlights, rear lights, & windshield wipers, would suddenly stop working then work again. I totaled my Jeep and I’m now out of a vehicle since I had a active loan of the vehicle....

Transmission suddenly stopped accelerating when pressing pedal. In reverse suddenly began making a whirring sound. 155,000 miles

The vehicle has a significant safety recall out with no timely identified repair offered. Jun 09,2022 Manufacturer Recall NumberZ46 NHTSA Recall Number22V-406 Recall StatusRecall Incomplete, remedy not yet available How can the manufacturer expect people to feel safe driving with the possibility of a unplanned sudden stop putting their lives, their passengers lives and the lives of other travelers on the road at risk. If Jeep can't fix the issue they should replace the vehicles.

We have been unable to drive the vehicle for 9 months out of 12 due to it being in the shop. The latest was a OBDC of "Improper DEF used see dealership". It was at 3 different shops to remedy the issue the final one being Lithia Chrysler/Jeep/Dodge of Missoula #134. Even with the extended warranty they WOULD NOT cover the expense even though it was their warranty. We were told it was for labor, but labor was supposed to be covered. There is also a "Stop Sale" in place so we cannot even drive the vehicle anymore due to lack of power. The dealership and FCA told us that this was "NORMAL" and we just "HAD TO LET THE VEHICLE WARM UP FIRST" I have owned and operated diesel vehicles for a better part of 28 years. I have NEVER had to do this. I cannot put my families...

While in motion, vehicle lost all power; the engine stalled, brakes failed and lost power steering. The vehicle shifted into neutral. I put the vehicle back in drive and it went back to neutral. I turned the ignition off and restarted. My husband was driving and I was in the passenger seat, with my 5 year old daughter in the backseat. If there had been oncoming traffic, we’d have hit them head on.

-What component or system failed or malfunctioned, and is it available for inspection upon request? Engine Issue with ticking, loss of power -How was your safety or the safety of others put at risk? Definitely it could affect me, my family and you when it stop any moment in the road, i did check dealer and mechanics shop abut the issue and mention it happen with other engine with same part number and i cannot afford paying a whole engine. -Has the problem been reproduced or confirmed by a dealer or independent service center? Yes -Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No -Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No

THERE IS A RECALL FOR FUEL PUMP DELIVERY. MYVWIFE WAS DRIVING THE VEHICLE AND IT COMPLETELY STALLED OUT WHILE DRIVING. VEHICLE WAS TOWED TO ARAPAHOE CHRYSLER AUTONATION JEEP, PARTS SUPPOSEDLY ARE ON BACK ORDER HOWEVER WE HAVE ALSO BEEN TOLD THAT THEY DON'T HAVE PARTS.

Vehicle only has 38,000 miles and suddenly had visible oil leaking from underneath. No warning lights came on but I took to service center for inspection. The oil filter housing was found to be defective and "leaking badly". Technician informed me that because the component is plastic vs. metal it is a known defect in my vehicle make/model. I also confirmed many complaints of same issue in online forums. I contacted manufacturer but since vehicle is out of warranty they would not assist. Service provider stated the issue is of significant safety risk as engine could lose all oil, overheat, and become undriveable. Cost to repair=$1800

The oil filter housing in the Jeep Gladiator, Wrangler, and 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. https://vehiclefreak.com/jeep-oil-filter-housing-recall-guide-2013-to-2017/?fbclid=IwAR372r_Z1vlEwSsMz6HmMA6_Vn1IEqL3SnyNYNGCuCVbH25-F7cUtjkhzpU

At a speed of 30mph, was slowing down coming up to a red light, as the brakes were being pressed the motor began to rev up and try to accelerate despite me fully pressing the brakes. I had to put the vehicle in neutral and shut it down. I merely missed hitting another vehicle. I called the dealer who had no information for me. No warning lights were on or prior to the reving and acceleration of the vehicle as I was trying to come to a stop at a red light. I am reading numerous forums of Jeep owners reporting the same issue. This really should be investigated before someone is seriously injured or killed, which maybe there have been reports of such already. In my case, there was no injury or damage because I was lucky enough to have no vehicle beside me and had a place to...

Noticed a wet substance under the hood and a smell of oil/antifreeze (couldn’t determine either or) coming from vents prior to purchase. I was told it would be looked at and taken care of. After purchase I noticed a heavy leak under the vehicle and when i touched it, I again smelled the same oil/antifreeze. I took it back to the dealership and they replaced the radiator. It continued to produce a leak, and chose to stop and get a diagnosis and they said it was the oil cooler. I then chose to return it to the dealership for repair and they insist it was left over spillings from the previous repair. It still has that same wet substance dripping from under the vehicle. I’m concerned about the safety of my life if it is indeed the oil cooler.

The contact's son owns a 2015 Jeep Grand Cherokee. The vehicle owner took the vehicle to the local dealer for maintenance and was informed that the oil filter housing had an oil leak and needed to be replaced. The vehicle was not repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 120,000.

While driving down the road my car will shift into Neutral while going at at full speed driving down the freeway, and loses all power. I have to pull over on the side of the road turn the car off and restart. This has happened 6 times and is very dangerous. There are multiple dates that this has happened. It looks as though this should fall under NHTSA recall #16V529000?

car engine has a sound of tapping. I research on YouTube ，it is rocker arms ticking when rocker arms broken. many complains about this problem of jeep v6 3.6 engines. it can cause engine brake down.

Plastic Oil Cooler leaking. This is a $800 repair, and seems to be a very common problem among Jeep Grand Cherokees.

Oil leak from oil filter cooler housing it has been recalled on 2014 jeeps but not the 2015 and it is the same issue

The oil cooler fails resulting in the entire cooling system being filled with the oil from the engine and possibly contaminating the engine oil with coolant. Even after the oil cooler is replaced the entire cooling system must be thoroughly flushed and have multiple parts replaced. It is a safety hazard because there is no warning, the oil cooler fails and all you engine oil is gone. Which will lead to catastrophic engine failure and possibly fire from the heat produced from the friction.

The contact owns a 2015 Jeep Grand Cherokee. The contact stated while the vehicle was in park (P), she started the vehicle and the vehicle independently accelerated. The contact stated no warning light was illuminated. The contact attempted to turn the vehicle off, and the vehicle would not shift into neutral (N). The contact stated that multiple attempts were needed to turn the vehicle off and restart the vehicle. The vehicle then started operating as designed. The contact had the vehicle towed to a local dealer to be diagnosed; however, the failure could not be duplicated. The vehicle had not been repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 98,000.

The contact's son owns a 2015 Jeep Grand Cherokee. The contact stated while her son was driving 60-65 MPH, the vehicle started shuddering. The ABS, traction control, and check engine warning lights were illuminated. The vehicle decelerated to 30 MPH and stalled while driving on an uphill ramp. The vehicle failed to restart, causing another vehicle to strike the driver's side of the vehicle. There were no injuries sustained. The vehicle was pushed downhill with the assistance of a police patrol. The vehicle was towed to the contact's residence. The vehicle was then towed to the dealer where it was diagnosed that the engine was blown and needed to be replaced. Additionally, the dealer diagnosed that the thermostat, radiator, starter, and motor mounts needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 116,000.

There is loud ticking/tapping noise coming from the engine when in motion or when the engine idles. This vehicle was not inspected by the dealer (out of warranty) or the police but was inspected by my mechanic and is available for inspection anytime, upon request. At time, the noise become extremely loud and scary and is a cause for great concern, especially knowing that this vehicle is mostly driven daily on the highway for at least 1 hour one way. This noise suddenly appeared about 9 year ago as a slight ticking/tapping but got progressively worse.

The vehicle has an oil leak problem which may be caused by the defect of cylinder head gasket, and some of other engine gaskets. The oil seal is problematic for this model.

Hello I’ve seen some oil leakage all over engine of car. Mechanic stated the oil filter housing has to be replaced but not covered under jeep warranty. car is driving ok for now .I’m at 79,000 miles. I’m concerned that this may become a bigger issue especially fire hazard when driving car.I’ve see similar issue on 2 other jeeps grand cherokees. I have not seen it come up as a recall but have seen multiple complaints.I feel that this is a mechanical issue and should be covered by Jeep.

The hydraulic lifter is failing causing the cam shaft to fail and need to be replaced. This is making a ticking noise and will only get worse. Chrysler knows this issue exists in the 3.6L pentastar V6 engines but will not recall and fix it.

While driving on the highway, the car suddenly started to generate a weird noise from the engine, and at the same time I was losing power, this was at 65mph. Now, the vehicle cannot go above 35mph without pushing down on the gas pedal. The RPM needle also doesn't move much. May be a Crankshaft Position Sensor issue as with the 3.0L engines.

The oil cooler/ oil filter housing cracked. My 2015 Jeep only has 49,000 miles on it. This is a huge safety problem. The oil leaked all over the transmission case and the exhaust. It was smoking really bad, this is a fire hazard!!! I found out that there has been many complaints on this issue and should be recalled for safety. The dealership told me to have it towed in because you can not drive it because it can catch on fire. Not good, someone can really get hurt!!! Recall this product.

Driving my 2015 Jeep Grand Cherokee, in Oct 2021 and this weekend, slipped into neutral while driving on the highway at 50+ mph and wouldnt shift back into drive. displaying the message 'VEHICLE SPEED IS TOO HIGH TO SHIFT' while at full stop Stop sign Both times trying to restart it, the engine would rev violently and shut off, only to restart after a few minutes and drive as normal. Both times in high moving traffic, narrowly avoiding traffic. The 2nd time I was on the NY Triboro bridge and used road flares to alert traffic Called the dealer and they claimed to have never heard of this before. Couldnt find any issues or replicate the issue. attached are several issues of other drivers having the same issue and still @Jeepc laims no knowledge. Does someone have to die to fix this issue

Bad Lifters and rockers on left camshaft caused loud engine tick/knock. Occurred at 62000 miles. An apparent KNOWN common Jeep FCA problem for 2015 JGC WK. Hard/ rough transmission downshift from 3rd-2nd gear along with loud bang noise. Downshift is so violent it causes your foot to slip off the brake pedal when braking. Occurred at 67000 miles. Another known common problem for 2015 JGC WK. This is a dangerous vehicle and should be recalled for these issues before someone is seriously injured or an accident results in death.

Once the shifter was moved into "Drive" , the transmission would automatically swith it to "Park" that would not allow any movement! It happened on the same day to all three of us. Several hours later, the transmission seemed to work. Waiting for diagnostic service at Umansky Jeep in Charlottesville, VA. This shifter movement could potentially lead to an accident! We occasionally tow a trailer and risk to other motorists and us would be substanstial! Please initiate invastigation sincere there a multiple complainst related to transmission.

I have a 2015 Jeep Grand Cherokee Laredo. While traveling down the highway at approximately 65mph, the entire dash began to blink in and out, all kinds of error symbols flashed, I lost power steering and the car switched itself in to neutral – this resulted in an accident. This car has been In and out of the shop for the past several months. Every time it looks like it fixed, the car’s computer seems to do as it pleases. I lose driving power, it switches itself in neutral or the dash throws error symbols. I am at a point where paying for constant ‘repairs’ and insurance is becoming way too costly. I do NOT feel safe riding with my family in this car!!!

The part that failed is identified as the Oil Cooler, I will request the dealer provide the defective unit. The part number for the Oil Cooler 68211323AB. There are two areas that would pose a safety concern when the Oil Cooler fails. When the Oil Cooler fails, oil is let into the cooling system. The oil level continues to fall to a point where it is very likely the engine will seize. There is no check engine indicator, the oil temperature indicator shows no rise in temperature. You would not know that there is any problem, If that happens while the vehicle is in motion it could prove to put occupants in jeopardy of injury. The second area of concern, as the oil bleeds into the cooling system it is unable to adjust for the additional fluid. The cooling system reservoir fills up and begins to overflow each time the...

The oil cooler failed with no warning, no check engine indication. All indicators returned normal readings. Without a warning you continue to drive while your oil levels are falling. All of your oil goes into your cooling system. The chances are very high that you will have your engine seize. At a minimum the failure causes major repair issues, if it can be repaired at all. One of the more troubling out come of the failure, the oil will eventually over flow the coolant reservoir into the engine compartment. The oil is everywhere in the engine compartment. This alone would present a number of safety issues. My car is currently at the dealer, I was quoted $8,600 to repair and replace all affected parts. My research has turn up a number of jeep, chrsyler and ram truck owners are or have experienced this failure.

The contact owns a 2015 Jeep Grand Cherokee. The contact stated that while getting a routine oil change shortly after, the warning light for a throttle box illuminated. The contact stated that in the past after getting the same oil change, the warning light for the tire pressure sensor light was illuminated. The contact took the vehicle to the dealer who determined no failure indicated for the tires. The contact stated that every time they brought the vehicle in for inspection no failure was indicated despite the contact filling the tires with air. The contact stated that while driving on the freeway when they were attempting to drive the speed limit of 65 mph their vehicle could not accelerate beyond being between 45-50 mph. The contact was able to pull off the ramp where the vehicle eventually came to a seize. The vehicle began to smoke on the front end....

The contact owns a 2015 Jeep Grand Cherokee. The contact stated that she heard a loud vibrating noise coming from the engine compartment while driving at various speeds. The contact stated that the check engine warning light was illuminated. The vehicle was diagnosed with needing the camshaft arms and gaskets replaced however, the vehicle was not repaired. The manufacturer was informed of the failure and referred the contact to the NHTSA for assistance. The failure mileage was approximately 75,000. Consumer was informed by the mechanic 3.6 liter engine in this vehicle is experiencing a common problem in this make /model.

Engine Rocker Arms bad. Engine stalls and vehicle undrivable. 96K miles

2015 Jeep Grand Cherokee with 3.6 pentastar. Bought the vehicle 10-2020 and had issue with running hot due to faulty electric radiator cooling fan and thermostat and housing failure. Repaired the thermostat and hosing at local Jeep dealership. 2 weeks later, radiator cooling fan froze and ceased operation, replaced by independent repair shop. Within a couple the oil cooler and filter housing adapter developed a crack causing a catastrophic oil leak.
