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.

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.

Constant ticking noise coming from the top of the engine. This ticking noise is made from worn out rocker arms/ cam lifters as the camshaft rotates. The bearing material in the lifters is not hardened steel and can degrade. All 3.6l pentastar engines are affected by these defective rocker arms. If the rocker arms are damaged no code will show. The first sines will be a loss in fuel efficacy. As the camshaft wears down changing the displacement of the cylinders this will start causing misfire and stalling during normal driving/ acceleration. Eventually, ware debris can fall into the cylinder and damage the head. I first took my jeep to the dealership at 60k miles to diagnose. With no codes showing I was told everything in the engine checked out and the ticking noise was from the valves. Now at 84k miles one of the rocker arms is definitely failing and still not showing codes. The dealership will not cover replacement under warranty because the purchase date was 5 1/2 years ago. This is a known issue with the 3.6l pentastar. Chrysler has provided technical bulletins to visually identify defective rockers but are not providing extended warranty or recall on this part. While at the dealership the technician said they handle a lot of rocker arm replacements on pentastar engines, 5 to 10 a week! Chrysler should take responsibility for sourcing and installing defective parts in their engines.

Numerous events of sudden stalling of vehicle at high speed in drive, at low speed in drive and reverse; creating a very dangerous situation involving near-miss rear end collisions. Can take up to 15 minutes to restart engine. Engine sometimes appears to restart with a ticking sound, has no power and automatic transmission can't be shifted into drive or reverse. Other times, engine starts and transmission can be shifted into drive or reverse, but gears do not engage. Numerous events, as common as stalling events, involving sudden and sometimes violent shocks to the drivetrain, which happen at all speeds, usually when accelerating. Everyone knows this is a tipm issue, with serious safety implications related to the potential for high speed rear end collisions by following vehicles, that chrysler and the federal safety agency have not taken adequate action to remedy except on limited affected vehicle types. Substantial information exists on this known issue, including information and documentation submitted to chrysler and the federal safety agency. This particular vehicle was purchased new, started to exhibit this series of problems at the beginning of 2018 after 60,000+ miles, and has been back and forth to the dealer multiple times. There are no recorded error codes according to the dealer. The fuel pump relay has been replaced by dealer, supposedly, which was the latest unsuccessful attempt at solving the problem? Prior to that work was performed on the transmission, supposedly, which also did not solve the problem? Prior to the current symptoms, two unexplained dead battery events occurred. Now, readily found information shows a link with tipm and fuel pump relay failures that allow the fuel pump to run and drain the battery after turning off the ignition. How many more reports to the federal safety agency will it take to responsibly address this very serious potential rear collision safety issue related to the tipm?
