The vehicle is a 2018 Jeep Wrangler with a 3. 6l engine and approximately 124,000 miles. The engine has experienced a failure involving multiple components, including suspected head gasket failure, significant oil loss with no visible external leak, low oil pressure, and engine knocking. Diagnostic trouble codes p0365 and p06dd were present, indicating camshaft position sensor issues and oil pressure control failure. The vehicle is available for inspection upon request. This condition creates a safety risk due to the potential for sudden engine failure and loss of power while driving, which could occur without warning and increase the risk of an accident. The problem has been confirmed by an independent repair facility, which identified low oil levels, coolant loss, and symptoms consistent with internal engine damage. The vehicle has not been inspected by the manufacturer. Prior to the failure, warning signs included a low oil pressure condition and engine performance changes. These symptoms developed rapidly over a short period of time. The vehicle is currently not safe to operate due to the risk of further engine damage or sudden failure.
My wife and I were at a stop light behind a box truck in our 2018 Jeep Wrangler, about 15 feet between us. I had slowed to stop and had my foot on the brake. All of the sudden the Jeep reved up (idle increase), did not see the tachometer, and with my foot on the brake accelerated into the box truck in front of us. When it started to accelerate, I pushed the brake peddle to the floor to stop the Jeep but it did not do a thing. I see 2 problems her: 1. The acceleration when stopped 2. The brake did not hold. There were no injuries or damage to the box truck. We were able to drive the Jeep about 20 miles to the dealer we bought at. It is ow being worked on in the body shop. The Jeep dealer technicians did a computer check on any codes that were activated, but unfortunately all after the fact.
The fuel pump relay that is embedded within the totally integrated power module (tipm) failed on my 2018 Jeep Wrangler jk unlimited after only 47391 miles, causing intermittent engine stalls and problems starting. When taken to the sisbarro deming, nm cdjr dealership for repair, there were no replacement tipms in the stock system available to fix my vehicle, despite my vehicle being only 7 years old. This suggests an abnormally high rate of failure if the manufacturer is unable to maintain an adequate stock to support their vehicles. Given this has been an issue with Jeeps of previous model years (1), it is evident the problem has not been addressed yet. . Read more...
The vehicle experienced a fuel/propulsion failure involving sudden loss of engine power. After internal engine repairs performed by the dealership (camshaft and valvetrain work), the vehicle was returned to me as repaired and safe to operate. Within minimal post-repair driving (less than one mile), the vehicle entered limp mode, lost propulsion, and the engine shut down while driving in active traffic. The vehicle required towing back to the dealership. The loss of propulsion occurred on a busy city roadway and created an immediate safety risk to me and surrounding motorists due to the sudden inability to maintain speed or power, with a foreseeable risk of collision. The problem has been confirmed by the dealership. After subsequent inspection and teardown, the dealer documented catastrophic internal engine damage, including cylinder wall scoring and a failed head gasket. The dealership acknowledged that deeper inspection during the prior internal engine repair would have revealed the need for engine replacement. The vehicle has been inspected by the dealership multiple times and by the dealership’s insurer. The manufacturer (stellantis) has opened a customer care case. The vehicle is currently available for inspection and has been removed from service due to safety concerns. Prior to the failure, the vehicle displayed warning indicators and messages at the time of the incident, including limp mode activation and critical alerts immediately before and during the shutdown. No warnings were provided to me at the time the vehicle was returned from repair regarding unresolved internal engine risk or potential loss of propulsion.
My 2018 Jeep Wrangler jl sport is experiencing multiple premature engine failures that present a serious safety risk: •vehicle overheats while driving. •recurrent misfire on cylinder #5 (dtc p0305). •white exhaust smoke with a sweet coolant smell on cold start. •coolant loss despite recent refill. •oil contamination with metallic particles found during inspection. •valvetrain noise from the right bank, suspected intake camshaft wear. These conditions create a risk of engine seizure or sudden stalling while driving, which could cause a crash. Manufacturer awareness: Jeep/mopar has issued bulletins acknowledging these exact problems, including: •TSB mc-11018482-0001 (may 2025): intake camshaft/rocker wear causing misfires (p0301–p0306). •customer satisfaction notification zd8 (2023): coolant inlet tube fastener issue causing coolant leaks and overheating. My vehicle’s symptoms directly align with these known manufacturer issues. Despite this, Jeep/mopar has denied goodwill repair coverage. Safety concern: this defect is not just a performance issue — it creates a high probability of sudden engine stall or seizure, endangering me, my passengers, and other drivers. I am requesting NHTSA investigate premature engine failures on the Jeep Wrangler jl (3. 6l pentastar) and require Jeep/mopar (stellantis) to address this safety hazard.

There is a recall, 19a, that has no fix yet. The "this-might-happen" happened to me. Clutch plate hot, hole through transmission, near melted fuel lines. Got it fixed, major work $6000. Chryselr won't reimburse me because "there is no fix for the recall yet. " that is the point. My car sustained major damage due to the recall issue with no fix. When they do find a fix, the replacement parts that I have now will still have to be fixed. Nothing, including 3 weeks rental, covered under extended warranty because it is a recall issue. Recall reimbursement documentation not processed because there is no fix. They have been running me around for almost 2 weeks. I am not someone who can drop $6000 without major pain. I paid with what cash I had, financed what I could at 23%, and had to have a friend use her credit card for the rest. I have nowhere left to turn.
I had the y03 recall done on August 30, 2021. My 2018 Jeep Wrangler jl sahara unlimited has 53,00 miles. On my way home from vacation, June 4, 2022, my clutch plate overheated, exploded through the bell housing and transmission, burnt the wire casing, and melted the fuel line. I had to leave my Jeep in nc and get a rental car to make it home. After being at a dealership 7 hours away from home for a week in jacksonville, nc, I am told by the dealer that Chrysler will not honor my powertrain warranty because the clutch is not a covered component; however, the issue that occurred with the clutch and how it occurred is exactly what both the y03 and w12 recall said could happen. The w12 recall is still showing "incomplete in every location I've checked, including Chrysler and mopar; however, I am being told that the simpler fix noted in the y03 recall supersedes the w12 recall instructions - which required service techs to perform a hydraulic clutch system bleed and also perform of clutch health check procedure; whereas the y03 skips these steps. I spoke to someone at mopar who told me that all components related to the recall (I. E. The clutch) have a 2-year warranty after the recall is completed, but any other components affected by the clutch failure are not covered. How can Jeep/Chrysler know there is an ongoing clutch issue specifically with the clutch plate and not honor/cover repairs that result because of it? and, how can a wire sheath and software update guarantee the potential failure is resolved if the clutch is never inspected to make sure the clutch plate hasn't already been compromised because of excessive heat? I have already filed a complaint with nhsta, spoken to Chrysler corporate (without any luck). Chrysler and mopar should stand by their parts/vehicles when something catastrophic like this happens. Had the fuel line caused a fire, my Jeep could have exploded or caused a serious accident/death/injury.
Just took my 2018 Jeep Wrangler unlimited jl in for the improved steering feel recall. The Jeep was working just fine until after the software update just miles after update lost all power and shut off and wouldn't restart. I couldn't even get it to turn over enough to put it in neutral to put it on a tow truck. Finally got it restarted, back to the dealer and was told fuel pump was out. Service bulletin #s1808000167, fca discusses the reasons that the vehicle won’t start or there is lost contact with the fuel pump control module.
My 2018 Wrangler accelerates when not on the gas pedal, and both the engine light and electronic throttle light comes on. My Jeep has been to the dealer 4 times for this issue and it still goes unfixed. It has been to an independent service center once, and they diagnosed the pcm (powertrain control module) as failing. This issue is very dangerous for myself and anyone else on the road as my Jeep will accelerate at random.
Vehicle is under recall w12/NHTSA 20v-124. Fiat/Chrysler (fca) has been stalling us for quite a long time. The clutch pressure plate may become overheated and fracture the transmission, which can result in personal injury, or the car getting fire. The dealer says that Chrysler doesn't have the part required to fix the car, and fca keeps routing me from one representative to another, but they won't even say if they have the part. I have been making payments diligently on a car that cannot be driven, as the statement on their own letter informs that the recall pertains to a serious safety issue. My car has been to the dealer and deemed that there is a leak and the clutch hose so I shouldn't drive it. The clutch already feels extremely soft and I am afraid to drive it. Fca does is not offering any hopes of fixing nor is providing any information regarding a timeline.
Vehicle was being driven approx 30mph on a city road when a loud bang was heard. Immediately pulled over and luckily a stranger following behind quickly escorted the driver out as the vehicle completely went up in flames. Metal chunks and pieces could be heard falling underneath the vehicle. Upon closer inspection the transmission had completely exploded and ejected the clutch assembly shearing the input shaft and rupturing a fuel line. The vehicle was a complete total loss with flames immediately entering the passenger cabin in seconds. If it was not for a brave bystander serious injury or death would have occurred. This is a new transmission introduced in the new jl Wrangler and gladiator and has been happening more and more. It's a serious safety issue that Jeep refuses to look into and needs to be investigated immediately. Transmission explosion to this degree not only can result in a fire but also metal projectiles hitting bystanders and coming through the floor boards and possibly resulting in injury or death. If you are reading this and have a manual Jeep Wrangler have it checked immediately! this was a completely unknown problem showing no symptoms whatsoever.
Vehicle seems to rev up on its own/gas pedal feels like it sticks.
