Engine Clicking And Tapping Noises Problems of Jeep Wrangler - part 1

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.

I only have 56,000 miles on my 2014 Jeep rubicon unlimited and the motor is already making a ticking noise. . Not only do I change my oil at the recommended mileage I also buy the most expensive and the best oil so I wouldn't have to deal with something like this.

I get frequent oil changes and I noticed that the last two oil changes it started making this ticking noise. I brought it to my mechanic and he told me that after the next few oil changes it should go away. Than my other mechanic that heard this ticking noise said that it was serious and this has something to do with an engine part callled a lifter. I nervous when he told me that if it's not fixed the engine could seize. I just bought this Jeep from a dealer not knowing this was a common problem among Wranglers. I did my research and came to the conclusion that it has nothing to do with the mileage but more so on how the engine was built. I spoke to number of dealerships and they fix this common problem on all ages and mileage Wranglers. The estimated cost of repair would range from $2000 and up. I don't think we as consumers of this product should be repairing an engine problem from Chrysler. I don't have any pictures yet til the dealership opens up the engine.

Vehicle only has about 66k miles and after a new oil change, I could hear a ticking noise coming from the engine bay. After taking it to a mechanic and researching for similar issues from other Jeep owners. It seems the 3. 6l pentastar engine is notorious for having a camshaft or lifter go bad.

The lifters (headers) have gone bad. Incredible ticking noise from the engine in drive and idle. As rpms increase the ticking is louder. The only way to fix is to replace the headers. I have read a multitude of complaints on the NHTSA page regarding this and additional complaints all over Jeep forums that this is a known issue with the 2012 engines . . . Why is this not been recalled?.

With less than 400 miles on the vehicle, a tapping sound could be heard from the engine bay. When it was brought into the dealership for service, it was determined that there was an issue with the engine. The service technician stated there was a camshaft issue for a tappet that had failed and was delivered from the factory with the defect. This has resulted in a replacement of the rockers, tappets, and intake and exhaust camshafts.

First owner of vehicle. Issues began with engine light appearing/blinking & vehicle struggling to run within 15k miles. Dealership diagnosed as cylinder misfire & repaired. Has occurred multiple times over life of ownership- always diagnoses as misfires. At apx 75k miles, upon cranking & during operation, heater became inconsistent in operation & this is still an issue. At apx 80k miles, upon cranking & during operation, ticking noise from front passenger side began. Faint at first & became increasingly louder within several days. Out of warranty. Solid check engine light began to appear off/on, remaining on for 24-48hrs then off 24-48hrs. Air conditioner conditioner has about a 15 sec delay before it turns on at every crank & power light for a/c slowly blinks until after the delayed start. Mechanic found 2 rocker heads damaged & they were replaced. Light not on at repair & code could not be pulled. Within 2 days of repair, a faint ticking noise became present on drivers side. Has been a week & ticking is now extremely loud. I am one of many with parallel issues & request this be addressed as my year & VIN do not fall in to the approved extended warranty to cover these very same issues.

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.

Ticking noises when vehicle in motion for highway driving and city driving. Left cylinder head cracks.

I purchased a 2014 Jeep Wrangler unlimited with the 3. 6 liter pentastar engine. I bought it with 75k miles. After driving about 500 miles, there was a very loud ticking noise coming from the left side of the engine. I contacted the local Jeep dealer and was told that this is a very common problem and said the repairs start at $2,200. I did some research on the internet pertaining to this ticking and numerous videos on youtube showing how to repair the lifter noise. This is a known problem and I feel Chrysler should make the fix.

When my 2014 Jeep Wrangler jku is running, there is a loud engine ticking noise that is coming from the driver's side of the engine. It is a lifter that needs to be replaced as well as the cam. The Jeep runs fine, but the noise is troubling. It's a costly repair!.

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.

At 41,900 miles a noticeable clicking/tapping noise anytime the engine on. It came on suddenly and when mechanic heard it he thought rocker arms or lifters have failed . Had diagnostic and mechanic found 2 rocker arms were bad . Thankfully cams without damage per mechanic likely due to seeking repairs so quickly.

Engine clicking sound !!.

There is a ticking noise coming from cylinder head. This is a issue that a lot of 2011-2012 Jeep Wranglers have been having. It is not fair that this cost should come out of our pocket. Jeep knows about this issue from all the Jeep reviews I have seen people posting with the same issue.

At approximately 12k miles I noticed that when the vehicle was started and moved from the street to the driveway and turned off before it could reach normal operating temperature, upon restart, there would be a puff of blue smoke from the exhaust. The dealership investigated and said that they could not duplicate the issue. At 20,500 miles the vehicle was running poorly and the check engine light came on. The dealership said a fuel injector had gone bad and they also found 3 bad engine rocker arms. The rocker arms were replaced under warranty. Incidentally, the issue with the blue smoke from the exhaust disappeared. At 28,000 miles the engine was beginning to develop an audible ticking noise. The dealership investigated and this time replaced 4 bad rocker arms. At least 1 of the rocker arms was the same one (#1 intake) that had been replaced during the prior servicing.

Purchased 6/26/19 w/ 49k mi; tapping noise develops at 54k; personal, highly qualified/experience mechanic referred me to dealer - tap was engine issue. On 10/14/19 dealer replaced lifters/cams/rockers (warranty until 10/20/19). Not normal on vehicle w/ only 55k. Dealer aware of cylinder misfires on jks but did no diagnostic test to determine why lifters/cams/rockers failed; did not perform inspection. Ten days later, cel with po302 (#2 misfire). Replaced plugs; coil code did not clear. Return to dealer who stated work was not related to previous work they just completed and acknowledged misfire is a common problem they routinely in Wranglers they service. Dealer also stated the 2011-2013 TSB extended warranty also applied beyond those model years to other engines from specific production runs but would not provide info. Filed complaint with Jeep cust care who said same - not under warranty, referred me back to dealer. Not asking Jeep to repair engine with excessive mileage or wear - I am asking Jeep to extend same coverage as 2011-2013 because Jeep has not corrected the problem. No engine with 55k miles should need the extent of engine work I've had done with low mileage. There are numerous documented complaints of misfire for Wrangler and class action suit filed for pentastar engine defects.

Ticking noise from the engine on both driver and passenger sides. The noise becomes louder when the engine gets warm, especially when it is close to a wall or other vehicles. Diagnostic from dealership says it is due to rocker arm failures.

Engine started ticking sounds like a valve or lifter.

3. 6 ticking noise sounds like lifters or rockers.

Engine began making ticking noise from engine bay at about 77,000 miles. Jeep has been serviced as required with quality synthetic oil and filters since new. Done more often than Jeep requires. Took to dealer who agreed it was making noise and needed fixed. When valve covers were removed they found rocker arms bad on 2 cylinders and tappets collapsed on 3 cylinders. Service manager said this was a common problem that Chrysler knows about. They have a star case bulletin, # s1309000016 published about this. Said they are doing several of the pentastar v6 engines a month. This is a engine that is used in Mini vans, chargers, challengers, 200's and 300's, maybe others. Happening in all of these vehicles. This is a known problem and Chrysler should have a recall for this. Rocker arm bearings not hardened correctly is what they told me. Being out of warranty, I had to pay out of pocket to fix this.

Left side of cylinder head ticking noise.

Ticking noise from engine.

Driving down the road when suddenly all the lights started flashing, radio flashed and then the Jeep started to loose power. Pulled over, put in park and turned it off. Exterior and interior lights were flashing. Clicking noises where coming from the tipm even with the key off. Everything was locked up once it was put in park and wouldn't unlock to tow. The only recourse was to unhook the battery and try to reset everything after waiting for about 20 seconds. I hooked the battery back and was able to drive it home. This is the second time this happened however the first time was in park and everything went haywire. Was able to restart w/o disconnecting the battery. It is getting worse. We are looking at a $1000 repair bill. We are hesitant to drive it.

My car recently started a ticking noise that will not go away. Ticking increases while vehicle accelerates.

A ticking noise. Valves ticking. I was told. That there is a recall on this with Jeep. Wranglers.

Vehicle received a check engine light while driving on the road and had a sudden power loss. With the engine started, the vehicle has a loud ticking sound from the cylinder head. Called a local dealer and they said the manufacturer extended warranty wont cover the repair because the vehicle has a salvaged title.

The day after purchasing a 2012 Jeep Wrangler, on 5/4/2017, with 49000 miles, while driving approximately 45 mph, an unusual ticking noise emitted from the engine with the illumination of the check engine warning indicator. The failure occurred until the engine was turned off. The vehicle was immediately taken to the auto dealership where vehicle was purchased for diagnosis. The technician stated that the failure was contributed to a faulty engine head and valve. The vehicle was not repaired. Problem has consistently happened for the last 2 months. Vehicle was taken to an authorized Jeep dealership but they refused to give us a diagnosis or offer a warranty recall stating the recall wouldn't apply as the car is a salvaged vehicle. The engine light illuminated after this episode and has not come off ever since.

The contact owned a 2011 Jeep Wrangler. While driving at an unknown speed, a clunking sound emitted from the vehicle and it stalled without warning. The vehicle was taken to an independent mechanic where it was diagnosed that the engine oil leaked out and caused the engine to fail. The vehicle was not repaired. The failure mileage was 68,000. The VIN was not available.

When the engine is running there is a clicking sound coming from the engine. I took it to the dealership, as they do all of my service and oil changes, and the technician said it was a known issue with this engine, and there have been several people complaining about it. They said it was the lifters in the engine that are making the noise.

There was not a fire but thought there was and 911 was called. I had the oil changed in March and again in July. In septermber there was a clicking noise coming from the engine and I pulled into a drive way and shut off the engine. I asked someone to look at it and when they tried to start the engine smoke came out of the vents and engine would not turn over. Turns out, that the Jeep had no oil in it and the engine burned up. The repair for a new engine is $5200. There were no warning lights at all. No "change oil notice", "low oil pressure" light, "overtemp" light, or "check engine" light. Had there been some kind of warning light before I ruined the engine it would not be so costly.

The engine has always had a ticking sound. It's been evaluated as a head replacement. The engine light has been on for months. Misfire #2 cylinder is the code.

Tl-the contact owns a 2013 Jeep Wrangler. While starting the vehicle there was an abnormal ticking noise. The check engine warning light was illuminated. The abnormal ticking noise is becoming more frequently. The vehicle was taken to the local tates auto group 505-906-6752who stated that the vehicle was working as designed the vehicle was not diagnosed or repaired. The manufacturer was contacted but did not assist. The failure mileage was 3,000. Ap.

On numerous occasions my Jeep fails to start. When I insert the key in the ignition and turn to start, the lights on the dash lights up with a single click sound coming from somewhere in the engine compartment. After continuously trying over and over to start the Jeep it would finally start. Some days it would take hours to start up. The problem occurs in any weather, day or night. Some days the Jeep starts up fine on the first try, other times it is a nightmare and takes all day to start up. I have taken the Jeep to the Jeep dealership before for a diagnostic, but it was useless and a waste of money for me since the problem is still occurring! after researching online, I have noticed many people having similar problems. Due to expired warranty, I can't afford to continue to pay for parts that could probably fix the problem. An individual on-line posted a Chrysler star case # 6505315 two years ago that could possibly help, but in the mean time there is no recall for this problem. If you want more information, check out Jeepforum. Com under 2008 jk starting problems. As for now, my Jeep is parked at work once again until it decides it wants to start up again.

I own a 2011 Jeep Wrangler rubicon unlimited which I purchased as a new vehicle. It presently has over 90,000 miles on it. Recently, I noticed a ticking sound coming from the motor - detectable from outside the car, but not noticeable when driving. A fellow at a car wash mentioned that he had the same issue with his Jeep and said that the issue turned out to be "valve lifters" and that the problem was resolved under the car's drive train warranty. I took my car to a dealer in for a regular oil change and asked to have the ticking sound checked by a mechanic. I was told that the sound was coming from the "top end" of the motor - and would have to bring it in again for a more lengthy evaluation - which I did. I made an appointment for service - took the vehicle in - and rented a car for what I expected to be several days of service. That was about a month ago. Subsequently, I've been told that the repairs to the top end of the engine did not resolve the problem and that the entire engine would have to be replaced. The dealer apparently ordered a "long block" replacement engine from Chrysler, but has been having problems obtaining other parts that are involved in the repair. The dealer also told me to contact Chrysler's warranty guys about seeking some relief for the cost of the car rental - which I did, but to no avail. I should add that I have been continually assured that the engine replacement is covered by the car's drive train warranty. However, I also came across an article in "autoweek" detailing problems Chrysler was experiencing with Jeep engines of my car's vintage - and that the engine replacements were being exacerbated by failures in chrylser's parts supply chain. This had resulted in both nhsta's involvement and to payments to other owners to offset the financial burden of the attenuated warranty repairs. I'm reporting this on this basis.
