Further, they cannot source the chips for the components, the make cannot provide a delivery date.(UNKNOWN when this will be rectified. Other years of this car have been recalled for this issue.

    The vehicle exhibits a persistent valvetrain ticking noise associated with the rocker/lifter/cam components of the 3.6L Pentastar V6. The engine makes a rhythmic metallic tapping at idle and during acceleration. The noise has progressively worsened, leading to rough idle and occasional misfires. This issue is documented in multiple Stellantis technical service bulletins (e.g., TSB 09-015-24 and TSB 09-011-25) which attribute the noise to hydraulic lash adjuster and cam/rocker wear. If unaddressed, the failure can cause camshaft damage, metal debris contamination, loss of power and potential engine stall, posing a safety risk. The vehicle is available for inspection. The problem has been confirmed by independent mechanics who recommend replacement of the rocker arms, lifters and camshaft to prevent catastrophic engine failure.

    In 2020 I bought this Jeep, within the first 3 months I had to replace the TIPM, at $950.00, now 5 years later the same problem, the TIPM is having issues again. Causing the engine to overheat. Jeep is telling me this happens, not at $950 every 5 years, I was told there was a recall initially when they were new. There has to be some sort of recourse, you just can’t sell faulty parts and say it just happens!

    I was driving through a parking lot, I made a left turn and the airbag light lit up on the dashboard.Then, a chime sounded, like a low fuel chime or door open chime. I turned off the jeep and went inside the store, I then returned to my jeep, started it back up, and drove home. Every time I’m at a low speed, and make a left turn, that same chime sound starts to chime and the airbag light flickers. A scan detected the following: B1B06(1/3)Active B1CDC(3/3)Stored B1B56(2/3)Stored I checked for a recall, but can not find anything helpful.

    I am reporting a persistent and safety-relevant defect in my 2012 Jeep Wrangler with the 3.6L Pentastar engine. The vehicle is experiencing misfires on multiple cylinders, especially cylinders 1 and 5, triggering codes P0300, P0301, and P0305. These misfires result in loss of power, hesitation, and rough idle, creating serious safety concerns during acceleration or highway driving. Despite replacing spark plugs, ignition coils, the crankshaft position sensor, purge valve, and both oxygen sensors, the problem continues. The vehicle has just 83,000 miles and is currently at a certified third-party repair facility. Multiple mechanics believe the issue stems from known defects in the left (Bank 1) cylinder head or valve train components—an issue Chrysler previously acknowledged via TSBs and a 10yr/150k mile extended warranty on select VINs. I contacted Jeep Cares and requested goodwill support, but they refused to even discuss the issue because my Jeep is not at a dealership. This leaves owners like me with limited, expensive options despite being affected by a well-documented defect. Jeep forums and independent shops have seen widespread misfire problems on early 3.6L Pentastar engines, especially 2012-2013 models. I urge NHTSA to investigate this pattern of failure. The misfires impact driveability and safety, and the manufacturer has not offered sufficient resolution or consistent support to affected customers. I’m happy to provide additional information, documentation, or diagnostics.

    The 2012 jeep jk wrangler has serious electrical issues. The jeep randomly stalls while driving and sometimes won’t start at all. Right before it stalls, every light on the dashboard flashes and continues to flash until the car dies. Replacing the battery doesn’t fix the issue. Numerous complaints about jeep wranglers TIPM issues have been ignored by authorities. I suppose people will have to die in a crash or spends thousands fixing the TIPM or electrical issues before getting relief.

    For more than one year I have problems with the Anti-Lock Brake System Module - Mopar part #(68145835AE). Every time I place an order it get canceled because Jeep and or the supplier have the part on back order. I wonder when the NHTSA is going to intervene with this company, before an tragedy happens and someone get kill because the Jeep don't brake like is suppose to be.
