ELECTRICAL SYSTEM
We found cracks in the battery from swelling. We know for certain that the BPCM needs to be replaced. This issue is the same one the NRTA did a recall on for 2020+ Jeep Wrangler models. I had the issue fixed (was un-driveable) and it cost me over $4000. Looking for detail on why 2018 models weren’t considered in the latest recall.

ENGINE, ELECTRICAL SYSTEM
On August 6, 2025, while driving at approximately 65 mph on the highway, the vehicle experienced a sudden and total loss of motive power. The engine warning lights illuminated, and the vehicle would not accelerate, forcing an emergency maneuver across multiple lanes of traffic to reach the shoulder. This failure occurred just one day after a warranty repair for the same issue, and followed a previous 199-day repair for a known camshaft defect. This sudden power loss in highway traffic created an extreme and unreasonable risk of a high-speed collision and serious injury.

ELECTRICAL SYSTEM
Faulty CANBUS connector/CANBUS failure. This issue tends to be a random and inconvenient occurrence which can be difficult to initially diagnose. Causes the jeep to stall, power steering to fail, causes all dash lights to light up and keeps the jeep from start up. Acts as if the part needs to cool down before the jeep will restart. The failure of this part has caused the jeep to stall on the highway at high speeds. Two manufacturer dealers inspected the battery, auxiliary battery, alternator and starter; found no issue with those parts. One dealer said our issue was due to the ABS module; replaced it and it did not fix the issue. Replaced the CANBUS connector and the issue has resolved. This is a known issue among jeeps both new and old and can pose a serious safety risk. To answer the question of how fast the vehicle was going when this issue occurred; the failure of this part happens at both highway speeds and residential speeds. There are currently 52,XXX miles on our jeep and the failure started, roughly, April of 2019. Jeep was purchased, brand new, April of 2018. It started with the jeep failing to start then grew to the jeep entirely stalling out while driving.

ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM
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.

ENGINE
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

ENGINE
The Check Engine light illuminated and diagnostic code P219A was recorded (Bank 1 Air/Fuel Ratio Imbalance), and the engine has a ticking noise. The dealership has indicated the issue likely involves the valvetrain/rocker arms/lifters and will require engine internal repair (valve cover removal, spark plug replacement, possible rocker arm replacement) estimated at ~$2,900-$4,500. The 3.6 L Pentastar engine has been the subject of numerous owner complaints of ticking noise, power loss, misfire, and premature valvetrain failure. I understand there have been related Jeep Technical Service Bulletins (such as 09-002-14 and 09-008-18) addressing these types of failures. A class action lawsuit (Maugain et al. v. FCA US LLC) alleges defects in the 3.6L Pentastar engine’s valve train (rocker arms, lifters) and failure to disclose the defect. Maintenance History: Regular oil changes (every <6,000 miles) at approved service centers; no prior major engine internal repairs. Concern: The defect affects engine performance, may lead to catastrophic engine failure, and potentially reduces safe vehicle operation and control (power loss, hesitation). Relief Sought: I request the NHTSA open a vehicle safety defect investigation and compel FCA / Chrysler / Jeep to evaluate this condition under recall criteria.

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.

STRUCTURE:BODY
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.

ENGINE, POWER TRAIN, FUEL/PROPULSION SYSTEM
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.
