Engine Clicking And Tapping Noises problems of the 2015 Jeep Wrangler

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 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.

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.

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.

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.
