2015 Jeep Wrangler engine complaints
Page 3 of 6: complaints 41 to 70 of 133, newest first, as owners wrote them.
Faulty oil cooler. 2 different mechanics reported this as a common problem with 2015 jeep wrangler. Due to the way this model was made, the oil cooler is too close to the hot engine making it faulty. As well as the parts around it all have to be replaced. I've been told not to drive the vehicle due to fire hazard. The estimates I've been given are $1400 and up. I've also read many complaints about this same issue, same vehicle, same year, on several different web sites.
I’ve heard many complaints that the oil filter housing on the 2014 jeeps and up have had cracking problems
Vehicle engine light flashing while vehicle is on. Vehicle shaking, odometor and other gauges are sporadically flashing and shutting off while driving.
The contact owns a 2015 Jeep Wrangler. The contact stated that while driving at various speeds, the vehicle lost motive power and stalled. The contact stated that the failure had occurred several times while driving on a busy freeway. The failure also occurred while the vehicle was idling at a red light. After the failure, the vehicle was restarted and operated normally. The vehicle was taken to the local dealer who was unable duplicate a failure or determine the cause of the failure. The vehicle was not repaired. The contacted stated that after retrieving the vehicle the failure persisted. The manufacturer was also notified of the failure. The failure mileage was 113,000.
I have experience a complete loss of control of the vehicle on both highways and streets that are bumpy due to dips, potholes, rough conditions due to the road. I received a misfire on cylinder 4 code P0304 and was told my vehicle isn’t covered for any recalls, but see that this is a common issue in 2013, 2014, 2015, and 2017 models. I want to know if any recalls or lawsuits are going on because my dealership informed me there aren’t any and it would take a week to even be able to diagnose the issue.
My Jeep has a left cylinder head failure at 78k miles. Jeep forums are full of discussions regarding this issue. The dealer says there is no reason for the failure and that they have seen this before. Jeep says my warranty is expired so I am out of luck. This is my third Jeep and the first time I have had any issue mechanically. This failure is not from normal wear and tear. It's very frustrating that no recall on this obviously faulty engine part exists.
I had a 2015 2 dr Jeep Wrangler Willy's edition. In march 2023, after sitting cold in the driveway for 10+ hours, it spontaneously combusted. It was very obviously an electrical fire based on the smell alone. It appeared that the most damage was in the area of the battery and fuse box. Vehicle was completely totaled and I found many reports online of similar issues, including many wranglers that were completely totaled after the fire. There is no official acknowledgement of this recurring issue. The fire caught so fast, if I had not been parked in the driveway faced away from the house, I might not have a home either. Insurance did not do an investigation into the cause of the fire.
Oil filter housing assembly failed
My truck was making a loud clicking noise and kind or rattle. I took the vehicle in to be serviced. I was told that I needed to have all lifters, rockers and cams replaced. That these items being worn out is a known issue with Jeep Wranglers but there has not been a recall for this issue. The dealership replaced those items the camshaft exhaust, camshaft intake, arm valve, tappet valve lash, gasket cylinder and gasket intake. As stated by the dealership having to replace the lifters, rockers and cams is a known issue. Most people just trade the truck in. I would like to know if this is a known issue why has there not been a recall for this? Also because of the cams this caused the cylinder misfire in the engine.
The contact owns a 2015 Jeep Wrangler. The contact stated while driving 55 MPH, the vehicle stalled temporarily. There was no warning light illuminated. The contact was able to continue driving; however, the failure reoccurred while driving. The dealer was notified of the failure. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 141,200.
I have had the oil filter housing crack two times costing over 1 grand each time to have replaced by a shop. The lifters and rockers have gone out on each side of engine now with not even 91k miles on vehicle. Drivers side had 62,000 miles and then the passenger side had 91,000 miles on it. Maintenance has been done on time and not over due.
Oil filter housing leaking oil,build up of oil sludge on top of intake manifold,if build up persists it may cause vehicle to catch fire
Check engine light came on. Took jeep to dealership - indicated that the left side cylinder head needed replaced, not placing would cause extensive damage. The vehicle had 65779 miles on it and is in excellent condition, there was no reason for the engine to have such significant problems based on usage. Learned this is a faulty issue and that Jeep is aware of it, although no additional warranty or recall was provided. I was paid over $3,392 to get the issue diagnosed and repaired.
No crash or injuries. My Jeep only has 45,000 original miles and it is leaking oil from the oil cooler. I researched and this seems to be a very common issue with the 2015 3.6 L Jeep Wrangler. It cost over $1,500 to repair. As the other gentleman stated in his complaint, I feel this is a major issue that needs to be addressed by Jeep. See the other post below for further detail: I OWN TWO JEEP WRANGLERS, A 2013 AND A 2015. I HAD THE 2015 REPAIRED AT A COST OF OVER $1,000.00. NOW MY 2013 HAS DEVELOPED THE SAME PROBLEM; TO WIT, THE OIL COOLER/ OIL FILTER HOUSING CRACKS ON CHRYSLER 3.6 ENGINES AND THE OIL IS SPREAD ONTO THE EXHAUST PIPE WHICH HAS THE POTENTIAL OF CAUSING A FIRE. IF THIS IS NOT DISCOVERED, THE OIL WILL SPREAD TO THE REAR TIRES WHICH WILL CAUSE A TRACTION OR BRAKING HAZARD. CHRYSLER HAS NOT MODIFIED THE HOUSING AND WHEN YOU REPLACE , IT IS REPLACED WITH THE SAME PART THAT WILL FAIL IN THE FUTURE. CHRYSLER HAS TO KNOW THAT THIS PROBLEM EXISTS BY THE # OF UNITS THAT THEY HAVE SOLD, NOT TO MENTION THE THOUSANDS OF UNITS THAT ARE SOLD ON EBAY AND AUTOMOTIVE PARTS STORES. THERE SHOULD BE A RECALL ON THIS SITUATION BEFORE PEOPLE ARE INJURED OR KILLED.
There’s a ticking sound coming from my engine and it’s misfiring in cylinder 5 and the check engine light is on. My concern is it’s the rocker arm
Our temperature gauge says it’s overheating but it’s not overheating. We’ve had the radiator replaced twice. We’ve had it at three different places to take a look at it, we had the dealership look at it and says they can’t find anything. But it keeps losing coolant. This has been going on for the last 6 to 9 months can’t drive the car more than a few miles.
I own two jeep wranglers, a 2013 and a 2015. I had the 2015 repaired at a cost of over $1,000.00. Now my 2013 has developed the same problem; to wit, the oil cooler/ oil filter housing cracks on chrysler 3.6 engines and the oil is spread onto the exhaust pipe which has the potential of causing a fire. If this is not discovered, the oil will spread to the rear tires which will cause a traction or braking hazard. Chrysler has not modified the housing and when you replace , it is replaced with the same part that will fail in the future. Chrysler has to know that this problem exists by the # of units that they have sold, not to mention the thousands of units that are sold on ebay and automotive parts stores. There should be a recall on this situation before people are injured or killed.
My vehicle has been suddenly shutting off while I am driving. There is no warning that anything is wrong with the vehicle. The first time it happened was October 2021. When it has these failures they happen multiple times. The next day the car operates normally. There are no consistencies when this happens - it has shut off when I am driving 20mph and 60mph. There are no error messages that come up on the vehicle. I took it to Chuck Patterson and they were unable to retrieve an error code and refused to diagnose intermittent issues. They did not find any visible issues with the vehicle. I have an open case with Stellantis but they have not done anything. This issue has happened when I am driving my 2 year old nephew and is life threatening. Stellantis has not sent out anyone to inspect my vehicle. I bought the vehicle brand new special order and it has 104,000. I have not had any issues until now.
I have owned my Jeep since 2015 and bought it brand new from the dealership. I have replaced the thermostat three times already. Yesterday, 1-21-22, I was driving home on the interstate. The thermostat stuck again, would not open, and caused it to start dumping coolant out of it while driving. That caused the belt to slip and causing me to almost get into an accident trying to pull over. This Jeep has had several issues with overheating in the almost seven years I’ve had it.
2015 Jeep Wrangler 66,000 mi on it rocker arms are rattling need to be replaced it's a problem at all 2015 what I understand
I have 2015 Jeep Wrangler Unlimited Rubicon 1000,15 miles on and it has the ticking noise. I took it to my independent mechanic shop. The independent mechanic diagnosed the issue and said that the tick is coming from the passenger side of the Engine .I chatted with FCA to see if they can provide any assistance on this issue they denied even if the vehicle its out of warranty therefore is has to be cover out of my pocket cost.
My 2015 Jeep Wrangler with 80,200 developed the well know Pentastar Tick. The Jeep would misfire at idle when slowing to a stop light. The check engine light came on and the code was a P0304. I'm the original owner and took it to the dealer I purchased it from. They diagnosed the issue and called me stating that he Jeep needs new rockers and a cam shaft on the drivers side engine bank. FCA has known about this issue since 2012. I called FCA to see if they would provide any assistance to repair the Jeep. FCA refused to acknowledge that this issue exists and refuses any assistance for owners even slightly out of warranty even though it is a manufacturing defect.
The contact owns a 2015 Jeep Wrangler. The contact stated that while driving approximately 60 mph, the vehicle started to hesitate. The contact pulled over to the far right of the roadway. The contact then turned off the vehicle and while attempting to restart the vehicle, the vehicle failed to start-up. The contact had the vehicle towed to a certified mechanic who diagnosed that the starter had failed and needed to be replaced. The contact stated that while attempting to run the starter, the vehicle made a clunking sound and it was confirmed that the engine also failed and needed to be replaced. The vehicle was not repaired. The contact referenced the federal safety agency Campaign Number: 13V234000 (Steering, Power Train) as a possible solution to the failure however, the VIN nor the model year was included. The manufacturer was made aware of the failure and confirmed that the model year was not included. The contact was referred to the federal safety agency for assistance. The approximate failure mileage was 140,823.
Check engine light on, OBD codes P0016, P0390, P0394. Replaced camshaft and crankshaft sensors and problem still persists; limp mode up hills, and oil loss. Per MULTIPLE Jeep Wrangler forums, this is a very wide-spread Jeep phenomenon. Dealers do not know how to fix this. Jeep needs to own up to this defect.
I have a 2015 Jeep Wrangler with the Fiat Chrysler's 3.6 liter V- 6 Pentastar engine. The Jeep has only 44,465 miles on it and now has apparent design and manufacturing defects on the engine's left side , its the Pentastar Tick. The Tick Tick Tick is very loud and the engine will shudder, its only a matter of time before the engine shuts off on the highway when I am driving causing an accident. My dealer Hollywood Chrysler Jeep estimated repairs - need left side cams and full set of rockers - oil filter housing is leaking replace - replace abs sensor - coolant flush - carbon fuel cleaning -fluids service total $6,000.07 invoice # 584685. It looks like the cylinder head, gasket, cams, lifters and rockers need to be replaced. Chrysler needs to disclose these defects. Yes my jeep is available for inspection.
Apologies if this complaint is a repeat, but I keep getting a submission error notice whenever I try to submit this form. The jeep 4.0 liter six cylinder engine has a known defect with respect to the rocker arm bearings that causes a loud ticking noise in the engine and failure of the exhaust and intake camshafts. This happened to our 2015 jeep in january 2020 when it had only 31,000 miles but was one month out of warranty. Chrysler did fix it at that time as a courtesy subject to a $100 fee, and a copy of the invoice for that repair is provided. Unfortunately, a little over one year later, and with less than 10,000 miles having been driven since the initial repair, the same problem has reappeared. The dealer is now claiming the problem is with the remaining rockers that were not replaced, as it is chrysler's policy to only replace the rocker arms and camshafts that are damaged at that time. The service manager at the dealer says that they "see this all the time" and that they try to get all the rocker arms replaced when doing any repairs, but chrysler does not allow them to do so. Of course, chrysler is now refusing to cover the repairs, even though this is a known problem and should have been fixed the first time. This is totally unacceptable, and chrysler should be forced to do a full recall of all affected engines and pay for all required repairs. There are thousands of complaints about this problem online, yet chrysler still refuses to correct this problem.
Noticed significant knocking noise coming from engine that continued to get louder. Took to dealer for a nice 2 thousand dollar fix. Dealer replaced right side lifters, rocker arms, and both cam shafts. This sounds way too much like the 2011-2013 issue that jeep "fixed" and was under warranty for those it sounds like. Very coincidental and I am not the only one with these issues based on jeep forums
Cel on scan for code po302 cylinder 2misfire. R&r spark plugs, ignition coil, air filter, upper intake gasket & clean throttle body. Perform upper induction cleaning. Found misfire to return only on idle on cylinder 2. Perform compression test. Compression spec ok. Replaced plugs and coil again. There is a slight tick from cylinder 2 valve train area. Recommend going to dealer. Dealer: engine does have a slight tick. Performed a compression test and leak diwn test. Found liw compression and an 80% leak on the exhaust side of cylinder 2. Removed the cylinder head and found the exhaust valves burnt and excessive play in the valve guides. Replaced the left cylinder head, rocker arms and lifters. Cleared codes and road tested vehicle. Misfire no longer present. This is on a 2015 wrangler sahara unlimited with only 51,892 miles.
Started out with oil in the air filter, had the pvc valve and cam shaft replaced. Still got oil so an oil catch can was installed, then check engine light came on (air flow filter). This was causing my engine to not be able to accelerate beyond 70 MPH. They changed the sensor, but again, was unable to go over 70, and on an incline would drop down to 60 and could go no faster (no engine light this time). Next day got it up to 78, engine light came on, and again could not accelerate beyond 75.
