2018 Jeep Wrangler: engine overheating

Filed Sep 23, 2026 · Transmission · CA

FCA US LLC is actively violating the intent of Safety Campaign 23V‑116 by refusing to cover out-of-pocket consequential transmission damages. FCA’s own Part 573 Defect Report explicitly admits that the defective clutch pressure plate causes extreme friction, overheating, and fracturing capable of damaging the transmission case and nearby internal components. The vehicle operated under these defective parameters prior to the recall execution, subjecting the transmission internals to progressive thermal fatigue and severe structural vibration. This directly induced a premature internal mechanical failure less than 9,000 miles after the recall was performed. When a reimbursement claim was submitted for this consequential damage, Jeep Customer Care explicitly denied the claim under a corporate case file, stating the transmission components "are not covered under the recall repair," completely ignoring FCA's own federal defect acknowledgments. I am requesting a federal investigation into FCA’s systemic refusal to cover consequential powertrain failures caused by this safety defect.

2018 Jeep Wrangler rubber brake lines collapsing internally, trapping hydraulic fluid pressure, and causing front brakes to overheat/lock up. Happened last year on my driver's side. It completely locked up my caliper. Ended up replacing Front Driver Hose & Caliper. And both Front Rotors and Brake Pads. Now its currently happening to my passenger side. This time its actually causing a burning smell. Last year it did not it was just grinding. Been for a few months. At first I though it was my aux battery that was dead and was causing the smell. But got that looked at and didnt even have a ln aux battery. Didnt notice the smell for a few months. But now in extreme heat and worsen driving conditions it has came back. Was told my hose is collapsing. So now I have to replace rotors and brake pads again. And new hose and caliper on my passenger side

Recall 19A was a full clutch assembly replacement on January 2024 at 60,000 miles. I purchased the vehicle in January 2025 with 64,000 miles. I have owned the jeep for 1 year and 8 months. I now have 78,000 miles. Service transmission light comes and goes if the vehicle cools down the light goes off and drives normal. When the service transmission light is on the clutch is overheated and slips I can not move the vehicle out of 1st gear. I drove it to a dealer and they state I have a bad clutch it is overheating. I do not believe I should pay for a clutch after a brand new clutch kit was installed 17,000 miles ago.

The vehicle experienced repeated braking system failures that caused the front brakes to lock up while driving, overheat, and begin smoking. The front brake calipers, rotors, and pads were replaced multiple times,not lasting more than 3weeks before failing again. the problem continued to occur. The brake booster brake line and brake fluid were also replaced while attempting to diagnose the problem. Warning lights/messages appeared, including the ABS/traction control warning and “Service Electronic Stability Control.” The vehicle would also randomly turn off at stop lights and refuse to turn back on. An independent mechanic ultimately diagnosed a failure of the ABS control module. Showing a code “c2200” The vehicle is currently at the repair facility and is available for inspection. This failure created a serious safety risk because the brakes could engage/lock unexpectedly while the vehicle was being driven and the braking system became severely overheated and damaged multiple times. The vehicle is currently considered unsafe to drive unless I redo the whole braking system again and unplug the ABS module. I was informed that the required replacement ABS module is on national backorder with no reliable availability date and reliable refurbishes are also unable to do the repairs now. . I was also informed that obtaining a new replacement module may take an extended period of time. Because this is a safety-critical braking component, I am concerned that other vehicles with the same failure could experience unexpected brake malfunction or loss of safe braking control

I purchased this 2018 Jeep Wrangler JK Unlimited on July 19, 2025. Since purchasing the vehicle, I have experienced repeated mechanical failures that have required multiple repairs. The most serious issue involves the engine overheating at highway speeds without any visible coolant leak or clearly identifiable cause.Despite seeking professional diagnosis, the source of the overheating could not be determined. Shortly afterward, the vehicle developed a P0302 (Cylinder 2 Misfire), raising concerns about possible internal engine damage caused by the overheating.I believe this presents a significant safety hazard. An engine that overheats unexpectedly while driving at highway speeds can lose power or fail without warning, creating a dangerous situation for the driver and surrounding traffic. The vehicle has become unreliable and unsafe to operate because I cannot predict when it may overheat or experience another engine failure.As someone who often drives alone, I no longer feel safe taking this vehicle on long trips. I am concerned that the vehicle could leave me stranded on a highway or in a remote location without warning, placing my personal safety at risk. A vehicle should provide dependable transportation, not expose its occupants to the possibility of sudden mechanical failure.This vehicle has spent more time in repair facilities than on the road. I have incurred thousands of dollars in repair expenses, and I am now being asked to pay for an engine teardown simply to determine the cause of the failure before any warranty consideration can be made. Despite multiple repair attempts, the underlying cause of the overheating and engine problems has not been resolved.I am submitting this complaint because I believe the repeated overheating, unexplained engine malfunction, and resulting cylinder misfire may indicate a safety-related defect that warrants investigation. I request that the review to determine whether similar failure whether a broader safety issu

The instrument cluster display in my 2018 Jeep Wrangler Sahara has failed. The display is either blank or nonfunctional, preventing me from viewing critical vehicle information and safety warnings while driving. This failure affects my ability to monitor engine temperature, fuel tank capacity, warning messages, fault indicators, and other important vehicle operating information. As a result, I may not be alerted to potentially dangerous conditions such as engine overheating, low oil pressure, charging system failures, or other safety-related issues. I am aware that Jeep has issued recalls involving instrument cluster defects on certain Wrangler vehicles, but my VIN is not included in the recall. The symptoms of my vehicle appear similar to those reported in recalled vehicles. Because the instrument cluster is a primary safety component used to communicate vehicle warnings and operating conditions to the driver, I believe this defect presents a safety risk. I am submitting this complaint so the issue can be investigated and to determine whether additional vehicles should be covered.

I own a 2018 Jeep Wrangler that my 19 year old son drives for college. While driving, the vehicle jerked and became sluggish. There were no warning lights illuminated. I became aware that the front brake rotors had overheated again. I had the front right brake caliber and brake line changed back in 2024 and the issue has recurred this year. I had a local mechanic change the front brake pads and rotors for both front tires and caliber to right front side only in April/2026 and the issue has started again today. The vehicle was taken back to local mechanic to be diagnosed again. He stated that the brake fluid was unable to properly bleed through the brake line restricting air to fully purge from the hydraulic system, which can result in incomplete bleeding, reduced braking performance, uneven pad wear, brake drag, or brake fade and is part of the reason for burning smell near right front tire. He added that car isn’t safe to drive in this condition due to safety concerns of accidents due to inability to properly brake or even a fire. Vehicle hasn’t been repaired due to cost and I will attempt to contact manufacturer. The initial mileage reading when this issue occurred in 2024 was 90,000 miles. The mileage as of this complaint is 112,392.

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 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 the federal safety agency investigate premature engine failures on the Jeep Wrangler JL (3.6L Pentastar) and require Jeep/Mopar (Stellantis) to address this safety hazard.
