The contact owns a 2015 Jeep Wrangler. The contact stated that while driving at an undisclosed speed, the vehicle failed to accelerate into a higher gear and went into LIMP Mode. The ABS warning light was illuminated on the instrument panel and was also illuminated prior to the failure. The vehicle was driven back to the residence. A few days later, the vehicle operated normally, but the failure recurred after being driven several times. The vehicle was then taken to a dealer, where a technician diagnosed the vehicle's ABS module failure. The contact was informed that the ABS module needed to be replaced. The vehicle was repaired out of pocket. The manufacturer was notified of the failure. The failure mileage was 81,000.

The anti-lock brake system (ABS) control module on my 2015 Jeep Wrangler Unlimited failed, resulting in a C2200 internal ABS module fault. The failure disables the ABS, electronic stability control, and traction control safety systems. The failed component is available for inspection upon request. The initial symptoms were ABS, traction control, and stability control warning lights appearing intermittently. The issue was later confirmed through diagnostic scanning to be an internal ABS control module failure. As the condition progressed, the vehicle lost the speedometer signal and began experiencing abnormal automatic transmission behavior, including delayed shifting, holding gears longer than normal, and higher than expected engine RPMs. This appears to be related to the vehicle losing accurate speed information from the failed ABS system. The vehicle was inspected and diagnosed with the C2200 ABS module fault. The required OEM replacement ABS module is reportedly unavailable through normal parts channels and has been on extended backorder, leaving owners with limited repair options and significant repair costs. This failure presents a safety concern because critical driver assistance systems, including ABS and electronic stability control, are disabled. In addition, the loss of vehicle speed information can affect transmission operation and normal vehicle drivability. The problem appears to be a known failure affecting other vehicles of this generation, and replacement parts are difficult or impossible to obtain through standard repair channels.

am the original owner of this 2015 Jeep Wrangler, which I purchased new. The vehicle has been properly maintained according to the manufacturer's recommended maintenance schedule. I have records documenting routine maintenance, including regular oil changes. At approximately 75,000 miles, I began hearing a persistent ticking noise from the engine. Because I was concerned that the noise could indicate a mechanical problem, I scheduled an inspection with an authorized Jeep dealership. The dealership diagnosed the vehicle with a failed rocker arm that caused damage to the exhaust camshaft. The dealership advised that the intake camshaft remained in good condition, indicating that the failure was isolated to the exhaust valvetrain at the time of diagnosis. This type of internal engine failure at approximately 80,000 miles was unexpected for a properly maintained vehicle. My concern is that if this condition is not diagnosed promptly, continued operation could result in further engine damage, loss of engine performance, engine misfire, or potential engine failure while the vehicle is being driven, creating a potential safety hazard. While researching this issue after receiving the diagnosis, I found numerous reports from other owners of vehicles equipped with the 3.6L Pentastar engine describing similar rocker arm and camshaft failures across Jeep owner forums, Reddit, Facebook owner groups, and YouTube. Although I understand there has not been a recall for this condition on my vehicle, I believe the number of similar owner reports suggests the issue may warrant further review. I am submitting this complaint so that the federal safety agency is aware of the issue and can evaluate whether similar failures are occurring with sufficient frequency to justify additional investigation.

I have been working with multiple mechanics to diagnose an intermittent and unpredictable stalling issue with my 2015 Jeep Wrangler JK Rubicon Unlimited, VIN [XXX] . I have conducted the following repairs to attempt to fix the issue: 1. Rebuilt Transmission 2. Replaced throttle body 3. Replaced PCV 4. Replaced crankshaft sensor 5. Replaced camshaft sensor 6. Replaced Fuel Pump 7. Replaced fuel pump fuse 8. Replaced fuel pump relay fuse Mechanic and I have traced the problem to a likely fault in the TIPM. Due to unpredictability of stalling this has become a safety issue as the car will stall in traffic. Most often between 35-40 mph and below 2000 RPM...this is always while driving and is unsafe for both me and my fellow motorists. Most recent date is noted later in this form. If requested, I can provide receipts for professional repairs noted above, and receipts for parts I have purchased to replace myself.

I am getting ready to replace the oil cooler for the third time since 2022, how can I get a refund or maybe just recalling them. It seems to crack when I drive it every time it’s below 10° and I know this is not normal and it is not a cheap fix.

The radiator is poorly built and leaks, I have had mine replace several times by the dealership This is dangerous because it causes overheating in the engine which can cause hose to bust and engine to seize up . The oil filter house is engineered incorrect and all of them have been breaking causing oil to leak which again, ruins other components in the engine because of loss of oil. Its dangerous because the oil that leaks down through the outer portion of the engine, through to the sides and leaks over the bottom of the transmission onto the ground which is: 1. Environmental hazard- oil leaking causes water pollution, soil contamination, harm to animals and plants 2. Leaking oil is a FIRE HAZARD and safety issues for other vehicles causing slippery conditions for other vehicles 3. Causes engine damage and eventually failure I urge you to obtain the records of all the repairs jeep dealers did both under warranty and past the warranty dates. Your team will see what an issue this is and the 10000000s of Jeep Wranglers that have had these unsafe problems with the OIL Filter Housing and Radiator issues during and after the warranty. Jeep / Chrysler have created a deceptive way for revenue by allowing Jeep dealers to charge the customers for faulty engineering so they can gain profits in repairs that is the Manufacturer's own fault thereby gouging Jeep Wrangler owners.
