At around 85k miles the vehicle began developing a loud tick. It appears every vehicle with this motor or similar motor with the same internal Valve Rocker Arms have this problem. This Jeep problem is so bad that the parts are on a 2 month back order and every dealer admits they have a problem. The repair isn't cheap and entails the entire top of the motor to be exposed and virtually rebuilt. For a vehicle with only 85k miles this is a terrible situation that jeep has put their owners in. This is clearly an issue that should be rectified by the manufacturer.

The oil cooling housing. There was sludge around it and the lines from below the jeep ruptured. causing oil to leak all over the transmission bell. This caused smoking and over all engine. My dad a certified ASE mechanic has looked at it multiple times and fixed various components related to the cooling/heating system.

ABS and check engine light. I am a rural mail carrier, because my ABS light is on it causes my jeep to not accelerate pulling away from mailboxes therefore putting myself and other drivers at risk. The problem has been reproduced at the dealer. Warning lights illuminated at 19687 miles and are still on to this day, no resolution from Jeep. Jeep engineer came to dealership and could not say what was wrong with vehicle.
My vehicle suddenly stops running as I'm driving down the road. This is an reoccurring problem that happens every few days. This does not issue a code nor does the check engine light come on. There is no rhyme or reason to the issue. Electrical does not go out only the ability to push the gas pedal. I have to pull over and turn off the jeep. It comes back on and runs after waiting 10 minutes. This is a hazard and can cause a wreck. It's an common problem with Jeeps as reported on the forums.
For the past 2 years my Jeep has been stalling a lot, have taken it to 2 mechanics and 2 times to the dealer. None of them know what’s going on because there’s no light coming on, except for the first time it happened the ETC light came on but went away a few minutes later.
When driving down the road, the Jeep stops running. This is very dangerous and happens while driving at 55 mph. I’ve taken it to a mechanic and it will not throw a code. We’ve replaced the fuel pump, ignition, battery and alternator. Reading the forums and other online resources shows this is a common problem with multiple solutions. Jeep should recall any parts identified with this issue and be able to help correct this known issue. This is very unsafe. I do not have the money to spend and have no reliable transportation for employment. This has been such a hardship during such trying economic times.
Car surges at times when braking. Increased brake pressure to stop vehicle causes engine to accelerate rapidly when pressing hard to stop vehicle. Dangerous situation. This has happened numerous times when trying to stop at a traffic signal.
The oil filter housing assembly was found to be cracked during a routine oil change. The oil could leak into the transmission and eventually catch fire. A mechanic has confirmed this is the issue. It will cost approximately $800 to repair. The mechanic indicated he has seen this in the majority of Jeep Wranglers he has serviced and he doesn't understand why a recall has not been issued on this part. This part is made of plastic and can easily crack.
The contact owns a 2013 Jeep Wrangler. The contact stated that the check engine warning light was illuminated. The vehicle was taken to an independent mechanic who informed the contact about TSB: 09002-14. The contact was referred to a dealer. The vehicle was taken to the local dealer and diagnosed that the #6-cylinder head needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure but, no further assistance was provided. The failure mileage was approximately 116,000. Consumer stated he had to pay to have the work done even though there is a service bulletin put out by Jeep referring to this problem specifically.
I just left my house and drove 2 miles at 25mph. My brakes went out then my vehicle caught fire with me and my two children inside. It is being inspected by insurance but there were no warning signs besides my brakes going out.
My jeep started smoking smelt a badd oil burning smell and almost caught on fire when I finally got stopped looked under the hood and I could see oil floating on top of the engine everywhere and going all down the back of the transmission looks like a part or something may have a crack in it can't really tell oil is all over the under carriage all the way to the rear end has got all over the brakes had troubles and issues with its slowing down without it smelling like an oil fire and smoke pouring out of the brake assembly
Driving approx 65 MPH on highway. Rpm jumped then car lost power. Would not shift past neutral and unable to remove key. Auto door unlock failed. Vehicle was evacuated and then struck from behind at high speed.
I was leaving a grocery store and as I was turning onto the busy main road my jeep wrangler sahara unlimited stalled with no warning no lights it just died it would not start at all. After 20 minutes it then started. It was very dangerous because the person behind me could have hit me if there wasn't any other traffic. This has happened before at traffic lights where it would stall out of no where but then I could turn the key and it would start. I am terrified to get on the highway afraid it will do that again and harm me or others on the road.
Brought 2013 wrangler to dealer for constant p0304 code after replacing ignition coils and spark plugs. Dealer did a compression leak test to verify that the 4th cylinder head was bad and need replacing and will cost $3700.00 for the repair. I had asked about the service bulletin 09-002-14 and my vehicle is not covered under the x56 code extended warranty for the cylinder head. I called chrysler/jeep as recommended by the dealer, and they told me to call the dmv.
I was in motion on highway at 60mph dash lights and radio went off, the engine went off for about 3 seconds then everything came back to normal. This occurred 3 times in the next 10 minutes. Each occurance was the same. Ran fine after that for 30 mins. Has not reoccured. Total shut down is dangerous. I have heard reports of this happening to many jeeps.
Engine oil cooler has failed 2 times once at around 70k miles and again at 90k miles. Oil leaks on top of engine block and runs down the back to the transmission on to the exhaust and could easily cause a fire. Fiat does not care when I reported it and it is a very common problem with the engine in multiple vehicles. Dealer wanted $3,000 to replace it when the problem was 12 dollar o rings on the adapter. The plastic housing that sits on top of a hot engine flexes and allows the o rings to leak. There has to be a way to replace that part with something safer but they wont cause it would cost them to much money and good luck proving what happened to start the fire when the plastic housing just burns away in a fire or your engine blows to low oil.
When the jeep is put into reverse first thing after sitting for a while the vehicle stalls when the brake pedal is applied. If the break pedal is slowly released, the jeep will stutter and almost stall but stays running.
At low speeds, usually while braking, the jeep will lurch forward/accelerate.
Tl* the contact owns a 2016 jeep wrangler. The contact stated that after taking the vehicle to an independent mechanic for a tire change, the vehicle failed to restart. The battery was replaced however, the failure persisted. The vehicle remained in custody of the independent mechanic. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 75,500. The VIN was not available.
Jeep has developed a ticking noise that has become louder and louder, noise is present whether vehicle is stationary or in movement and increases with the speed of the vehicle. Mechanic advised that it is faulty rockers and that they need to be replaced. He also acknowledged this is an extremely common problem with all penstar 3.6l in all chrysler products.
My 2013 jeep wrangler started having a code that read "misfire on cylinder 6" at about 55,000 miles. After changing the spark plugs and ignition coils on the drivers side bank of cylinders (2,4,and 6) the trouble code still continued to pop up about every week or two. I then took it to my local jeep, chrysler, ram dealer to investigate further. After doing some research I found out that the cylinder heads on the pentastar engine in the 2012 and 2013 jeep wranglers were have many, many issues with the bad cylinder heads because of there was two different metals used between the engine block and the cylinder head causing it to warp and cause compression issues in the cylinder. Jeep was well aware of this problem but refused to this day to issue a recall. After the dealer took the engine apart to investigate, he admitted to the fact that it was a bad cylinder head. This misfire on cylinder 6 occurred mostly when idling at a traffic light or at very low speeds. The kicker in all of this even though jeep admitted a faulty cylinder head was the cause of the loss of compression, they refused to replace the cylinder head at their cost. Because jeep did not have my VIN number in their list to be repaired, it was up to me to pick up the cost. I did nothing in the time that I have had this vehicle (original owner) to make a cylinder head become warped. This was a problem with the pentastar engine from the beginning. Too bad jeep doesn't do the right thing and repair these pentastar engine issues at their expense rather than heaping more responsibility on the consumer.
My jeep shuts off while driving on city roads and going up hills with other vehicles present, no codes show up, dash lights turn red when vehicle is off, my jeep makes funny noises when turned off, take it to the dealership over 3 months since I bought it 3 months ago and they can't fix it. They don't know what is wrong with it. They've tired everything and still nothing. It's going back in again because it shut off on me going up a hill. This jeep is now becoming dangerous to myself. Yet the jeep still isn't giving codes. I had to go buy a car scan device plug it in and record data of what is going on with the jeep so that the dealership can see. Do I have to go off a cliff or get into a really bad accident before this problem is found or fixed. I've only had this vehicle for 3 months. I bought it on february 21,2020 and it started acting up on february 28,2020 and still is on may 16, 2020 and it is becoming a nightmare. I'm spending money to get it fixed because the dealership is charging me because my extended warranty doesn't cover it. I was told when I bought it that there was nothing wrong with it but that was a lie. I need help figure this out. The dealership didn't make sure that this vehicle was safely operational before selling it. It over heated because they didn't check fluid. My heated seats were burnt out. My dash lights flicker on and off. They replaced something behind my dash but it didn't fix the issue. I think it made it worse. As of right now my jeep shuts up at least once a week which puts me in a dangerous position because I get stuck either on the side of the road sitting sideways or almost off of a cliff or in the middle of the road with nowhere to go because I have no power steering the jeep does it start back up for anywhere between 5 to 15 minutes.
Tl* the contact owns a 2013 jeep wrangler. The contact stated that while driving approximately 65 MPH, when the check engine warning light illuminated and the vehicle decelerated to 20 MPH and loss motive power. The vehicle was taken to the local pepboys to be diagnosed. The contact was informed of a misfire on cylinder number 6. The contact was informed that similar vehicles were included in a manufacturer communications number: 10139897 (engine and engine cooling) warranty however, the VIN was not included. Five star chrysler dodge jeep ram of macon located at (3068 riverside dr, macon, ga 31210, (478)345-8899) confirmed that the VIN was not included in the warranty coverage. The manufacturer was not made aware of the issue. The approximate failure mileage was 98,000.
Vehicle has just over 65k miles on it and has been maintained properly with regular oil changes. Ticking noise on the passenger side of the engine. Turned out the lifters and cam shaft had failed. Replaced by dealer at a total cost of just over $2400. Based on numerous jeep forum visits and research, this is a part defect in the cam lifter and is epidemic. Fca is requiring owners to pay for their poor quality parts being installed in their 3.6l pentastar engines. Have fca issue a recall and reimburse those that have been charged to replace their faulty parts.
I went to have the oil changed and the technician found tsb 09-009-18 pressure relief valve had broken and all of the pieces were missing but two small plastic parts. They showed me the tsb and I was unable to drive the jeep until the oil filer adapter was replaced or the plastic parts could possibly migrate and blow up my engine.
