What 1,793 owners told NHTSA about the 2018 Jeep Wrangler 4-door 4xe

My Jeep began misfiring, giving a P0304 error code via the ODB. On June 2nd 2025, we took it to the Sandy Sansing CDJR Dealership. They determined that my 3.6L Pentastar V6 engine needed a new camshaft and lifters, despite having only 42,609 miles on it. To further complicate things, it took the dealership over a month to get a replacement camshaft in and installed, due to an abnormally high demand for replacement camshafts; this suggests a systemic problem with the engine, especially considering the problematic history of earlier versions of the 3.6L Pentastar V6 (1). https://static.nhtsa.gov/odi/tsbs/2014/MC-10069161-0335.pdf

The ABS module has failed on the vehicle. Attempts to repair it have been unsuccessful due to the part being back ordered for years.

NHTSA ODI 11693201

The part that failed on my 2018 Jeep Wrangler JL with 2.0L I4 Turbo or 3.6L V6 eTorque engine is the BPCM: Part Name: Battery Pack Control Module (BPCM) Part Number: 05057870 or 68381513AA My dealer advised the the battery was "bloated" and at risk of catching fire & exploding. Under further review, the very SAME part was recalled for 2020-2024 Jeep Wrangler plug-in hybrid electric vehicles. [XXX] Mopar advised that my 2018 Jeep Wrangler Unlimited Sahara with eTorque has a BPCM which is part of the 48V mild hybrid system, which is not installed in all Wranglers — only those with the eTorque system. I believe this setup in my Jeep is the SAME setup as in the 2020-2024 Jeep models which had the recall. There is much evidence of this same issue with the eTorque setup online to reference.

ABS module has failed and has shut off the cruse control system. The O.E. module is on national back order with no idea of it availability. The unit is still in the vehicle. Non-A.B.S. brakes work. How ever the traction control system is shut off as well as the cruse control system posing a greater risk to all. Search on several internet sites confirms that this issue has been noted to the manufacture with no resolution. Owners are left to find their own part and none are available.

My 2018 Jeep Wrangler JL has a known corrosion issue TSB31-001-19 and TSB31-002-20. Corrosion on doors and hinges and spot welds. I have called local dealers and they won’t help. I got with the Jeep help line and they gave me a case number and said they would not be doing anything about it. They never gave me the opportunity to send pictures of corrosion in said areas. There is a Goodwill program that I asked about and was refused so I’m reaching out to the NHTSA and BBB to get some help with this issue. This is a well known and documented issue and not owner negligence. The Case# given to me was 94287282.

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.

The primary component that failed is the brake caliper, which caused a dragging brake, overheating, and visible smoke after a brake pad replacement. This is a defect in a critical safety system, not routine wear and tear. The caliper failure, combined with rapid deterioration of the pads within only seven months of purchase, makes clear that the Jeep was sold to me with preexisting and undisclosed defects. The defective caliper and removed parts remain available for inspection. My safety and the safety of others were directly at risk. A dragging brake drastically reduces stopping ability, can cause sudden brake failure, and creates a fire hazard when smoke and heat build up. These risks make the vehicle unsafe for road use. In addition, there is a well-documented steering defect known as the “death wobble.” Some sources classify this under a recall, while others describe it as covered only by an extended warranty. This inconsistency has prevented me from obtaining clear assistance despite the serious safety implications. The issue has been reproduced and confirmed by a certified Jeep dealership. I have service records, dealer inspection notes, and photos documenting the condition, including metal-on-metal wear, dragging brake, and resulting smoke. The vehicle has been inspected by dealership technicians and is also under review with FCA, who have assigned a claim number. When I initially sought assistance, I was told the failures were “wear and tear.” That is inaccurate, as no reasonable consumer could cause this level of brake and steering deterioration in such a short period. I have been forced to pay out-of-pocket for defects clearly present at the time of sale, even though Carvana, SilverRock, and FCA denied responsibility. Under the Magnuson-Moss Warranty Act, consumers are protected when vehicles are sold with hidden defects, regardless of warranty status. This Jeep was sold in unsafe condition. The caliper failure and death wobble are preexisting hazards

I have brought my vehicle in for 3 time for the dealership to take a look at Europe messages I have received. It is currently with them right now.as the start stop function is now not working. This happened while in the dealers possession and was working normally prior to me being it into the dealership. They said they repaired a vacuum leak. After the apportionment I noticed the start stop function wasn’t working and it said battery charging. I took my vehicle on a long drive to charge the auxiliary battery, but nothing changed. I brought the car back to the dealership and they are now saying they are not responsible as a battery can drain at any time. I have asked for dates on their OBD scans but they either do not have them or are unwilling to provide them to me. I asked what systems the auxiliary battery affects other than the start stop function. They told me seat belts, dash lighting and obviously emission because the vehicle will not start and stop the way it is supposed to, and continues to run while sitting at a light or stopped in traffic. I am currently waiting on results regarding the start stop function.

I have experienced an Instrument Panel Cluster (IPC) display failure, and the vehicle is available for inspection upon request. This failure poses a direct safety risk to myself, my passengers, and others on the road. The display initially flickered and flashed, which created a driving distraction, and now it has gone completely blank. Without the IPC, I cannot monitor the speedometer, fuel level, warning lamps, or other vital vehicle information. I believe this condition violates Federal Motor Vehicle Safety Standard (FMVSS) No. 101 regarding the accessibility and visibility of required controls and displays, thereby increasing the risk of a crash. The issue has been inspected by an independent service center, which confirmed the failure and encouraged me to contact the manufacturer about a potential recall. There were no warning lamps, error codes, or messages prior to the failure. The first symptoms appeared a couple of months ago when the display began flickering intermittently. Since then, the problem has worsened to the point where the display now rarely turns on at all.

The contact's son owns a 2018 Jeep Wrangler. The contact stated while driving 25 MPH and pulling into a parking lot, the vehicle felt like one of the front tires was not rotating. The contact was able to pull into a parking space. Upon inspecting the vehicle, the contact noticed that the driver's side front tire was not rotating. The contact and a bystander noticed that the driver's side front tire was not rotating because the front brake caliper was protruding through the rim. The contact's husband arrived at the scene, removed the tire, and zip tied the caliper to the frame, and the vehicle was driven to the residence. The vehicle was taken to the dealer, where the brake pads, rotors, and the calipers were replaced; however, the failure persisted. The vehicle was towed to the dealer, where it was diagnosed that the front brake lines had rusted internally, causing the brake lines to collapse. The dealer informed the contact that the failure prevented the brake fluid to reach the brakes, which remained close to the rotors and had burned out. The dealer determined that the front driver's side brake line, rotors, calipers, and the brake pads needed to be replaced. The vehicle was not repaired due to the cost. The manufacturer was not notified of the failure. The failure mileage was approximately 90,100.

All of our warning lights would come on at once we would lose steering power then it would go dark. We’d have to pull over shut it off then we’d have to wait at least 30 minutes before we could get it back in gear to drive it anywhere. This has happened more than three times. We now have it in a dealership and want to know, I think there was a recall on it in September but we did not get a letter so we want to know how to file the paperwork to get this fixed very disappointed with this we just put 2500 into it for new camshaft and now this is going to cost us around 600. I don’t have the receipts right now to download but I can upload them when I get the copies. Just wondering what help we can get it was very scary when all the power shuts down we were very lucky not to be in an accident

My car randomly illuminates every light on the dashboard and my speedometer will say zero mph and I lose all power steering and have to put my car into neutral and roll to a stop because my brakes won’t work either. Then I cannot turn off the ignition or accessory. Check engine light is on and my car starts but there are no brakes or power steering. Thankful my kids were not in the car!

After filing my first concern with the vehicle and attempting to rack my brain with answers to why a 2018 is falling apart at the seams, I can only come up with either fraud, or the vehicle has been modified in major ways and glued together only to fall apart every bump I go over. After some reading I’m questioning 49 CFR part 565 form that was turned in after I purchased the vehicle means that I possibly have a replica, “remanufactured”, or altered vehicle. I’m not sure of the legality of selling a vehicle built from whatever vehicles I have, I do know that parts are not all the same years upon scanning modules I got some strange replacement identifiers that I will send. I also question if it really passed emissions being that my short term fuel trim sensor passed the catalytic converter on both sides stays over 99% consistently, also one of the “inspection” reports was done 2 minutes apart and the paper states that the vehicle passed at 5:08 then failed at 5:10 pm the same day. Not many vehicles tend to try again after passing and 2 minutes apart. I would have never bought a vehicle that not only has random foreign parts but a 2015 vehicle is also showing up under module information. I’ll never have recall information, and it seems that every system in the vehicle meant to warn or save me and my family when driving is compromised completely, yet somehow someone was allowed to pretend that I was buying a 2018 jeep Sahara unlimited with no record on carfax that what I am paying over 50 grand for with tax doesn’t just get bad gas and jump half the road when I hit a bump “because it’s a Jeep”. I should have been made aware that I was buying something scrapped, and that the odometer could be from any of them. I would like to receive a report of the form filed months after I purchased the vehicle and my entire jeep changed description and was no longer being monitored for safety. The IPC, BCM, TCM, and ECU aren’t properly communicating, and panels are all shifting.
