Jeep Wrangler Unlimited 2012 — Problemas relatados

While driving my 2012 Jeep Wrangler Sport, the vehicle experienced a sudden and severe loss of engine power due to a cylinder failure on the left/driver-side cylinder head (cylinder #2). This defect causes the engine to experience persistent cylinder misfires, resulting in severe engine stumbling, hesitation, and a dangerous drop in acceleration capabilities. This creates an immediate safety hazard when attempting to merge onto high-speed highways, pull out into active traffic, or navigate intersections, as the vehicle cannot accelerate predictably to match traffic speeds. Furthermore, the persistent misfire causes unburned fuel to dump into the exhaust system, creating a secondary risk of catalytic converter overheating, damage to the exhaust system, and a potential engine bay fire hazard. This vehicle has only 86,000 original miles. This specific 3.6L Pentastar engine generation is subject to a widely documented manufacturing defect involving premature valve seat and head failure, which manifests as an unpredictable and sudden loss of motive power while the vehicle is in motion.

Warning lights for Traction Control parking Brake and ABS are all on. Diagnosis is a Bad Brake control Modular. Dealer said it is super common and a defective part. They want $3000.00 to fix it but Mopar does not make the part anymore so they cant help me anyway unless I bring them one from a junkyard. Jeep forum says DO NOT Drive the vehicle with a bad Brake controller, and I quote the Mechanic "ABS module failure poses a clear and present danger to drivers, passengers, and others on the road”. so now what do I do? Cant get the part, the Manufacturer does not make the part, and the vehicle is a hazard on the road. Stelantis knows this is an issue for every Jeep Wrangler owner but does nothing to assist. They won't even produce a replacement part. PLEASE force JEEP to do the right thing and fix our ABS modulars

This failed part has not for me caused an accident but it could easily cause one. A failing or failed ABS module renders the ABS braking system useless. As well as no cruise control, traction control and throwing the jeep into limb mode whenever it decides. NO warning. Thousands of jeeps are affected and jeep knows it is a major problem with no solution in sight. This can be very dangerous with this many jeeps still being driven despite the dash warning lights. But for most these are their everyday driving vehicle and can't afford for it to just sit. Also not good for a vehicle to sit indefinitely. Some are still making payments on the jeep that is waiting on the module. Something needs to be done by JEEP to get these modules back to being manufactured. Some were offering repairs on the modules but now that has stop due to the chips being no longer available because now they are being made for the Data Centers. As they make more money on them than for the jeep. And used modules are going for well over $1000 and again they will soon quit working and will be back in the same situation. So before someone does actually get killed because of the lack of product get jeep to make the part available on a national level! This is for wrangler JK 2007-2018 and beyond. So many years of jeeps are being affected. The documents attached are the part and the famous code for ABS module failure.

The contact owns a 2022 Jeep Wrangler. The contact stated that while driving at various speeds, the vehicle unexpectedly went into LIMP Mode. The ABS, BRAKE, and traction control warning lights were illuminated. The vehicle was taken to a local independent mechanic to be diagnosed and DTC: C2200; was retrieved. The vehicle was scheduled to be repaired by the independent mechanic. The local dealer was contacted. The manufacturer was made aware of the failure. The failure mileage was approximately 120,000.

The abs module on many of these vehicles has a known fault. You can’t find replacement parts, even the Jeep dealership can’t get them. Many ppl are driving around with faulty modules, on a waiting list for parts. I’m one of those people. All has been fine until I was driving toward 228 business in Angleton to turn towards Walmart. I was going about 45-48 and went to brake to slow down for the stop sign. My brakes were soft instead of firm and it locked up and skid on me. I didn’t hit anything but had someone been behind me it could have been different. It scared me. Now I’m scared to drive it and have no fix for it.

The contact owns a 2012 Jeep Wrangler. The contact stated that while driving at an undisclosed speed, the ABS and traction control warning lights illuminated. The ABS, cruise control, and traction control features were disabled. The vehicle was taken to the dealer, where it was diagnosed with an ABS module failure. The contact was informed that the ABS module needed to be replaced. The vehicle was not repaired. The contact was informed that the parts were no longer being manufactured. The contact stated that the failure was a known failure with the vehicle. The manufacturer was made aware of the failure. The failure mileage was approximately 120,000.

For the past two years I have experience intermittent problems with my Jeep ABS system, I ordered the replacement module part # 68145835AE from an authorized dealership on April 2025, and paid $697.39 after more than a year on back order the sales representative told me to cancel the order because they did not have any information form Stellantis North America on when the part will be available. This is the second complaint I filed with NHTSA in a year and I plan to go up to the President if I have to since this is safety concern.

The engine's cylinder head/valve train has failed internally, allowing combustion gases to enter the cooling system — confirmed via a chemical block test performed by a master automotive technician on November 29, 2024, which verified combustion gases present in the coolant. This is a widely documented defect on this engine and model year, related to valve seat erosion in the cylinder head. Symptoms first appeared in June 2018 as an unusual higher-pitched, stressed sound from the engine. Over time this progressed to recurring, confirmed misfires on cylinders 1, 2, 3, and 5 (diagnostic codes P0300, P0301, P0302, P0303, P0305) and a mixture control fault (P219B). The check engine light has intermittently stayed illuminated for months at a time, then gone off for extended periods while the same fault codes remain stored and confirmed by a diagnostic scanner — currently the light is off but the codes persist. The vehicle frequently runs rough enough that the engine must be turned off and restarted to temporarily return to closer-to-normal operation. Noticeable vibration is felt during much of this pattern. Spark plugs, ignition coils, oxygen sensors, and the PCV valve have all been inspected/replaced and ruled out as the cause on multiple occasions over more than a year, isolating the cause to the cylinder head itself. This creates a driveability and potential stalling/hesitation risk, though no crash, injury, or fire has occurred to date. The vehicle has not been formally inspected by the manufacturer, police, or an insurance representative. The affected component remains in the vehicle and is available for inspection upon request.

What happened? The vehicle was delivered to an authorized dealership for a federally mandated "Stop-Drive" Safety Recall (V01 - Passenger Airbag Inflator). During this service visit, the dealership attempted to charge an illegal $275.00 diagnostic fee for the airbag warning light, which is directly related to the recall system.  The manufacturer’s corporate office confirmed via email that as of April 23, 2026, the recall remains "OPEN" and incomplete in federal records. However, the manufacturer also issued a contradictory statement claiming the repair was "concluded" based on dealer reports.  Most critically, while in the dealer's custody for this safety repair, the vehicle was lost or released to an unauthorized party. A manufacturer-arranged "Reunite" transport service arrived on-site to return the vehicle, but the dealership could not produce it, claiming it was no longer on the lot. The dealer has failed to provide any signature, identification, or surveillance footage to prove a legal release of this "Stop-Drive" recall vehicle. The Supplemental Restraint System (SRS/Airbag). The system is not available for inspection because the dealership lost the vehicle while the recall was still marked as "OPEN" and incomplete.  How was safety put at risk? The vehicle is under a "Stop-Drive" advisory because the airbag inflator may explode, resulting in serious injury or death. By failing to perform the repair, attempting to charge for diagnosis, and losing the vehicle, the dealer and manufacturer have left a high-risk safety defect unaddressed and the vehicle's location unknown.  Has the problem been confirmed by a dealer or independent service center? Yes. The manufacturer’s own database and the NHTSA/Mopar websites confirm the recall is "Incomplete/Open". Furthermore, a third-party towing company confirmed the dealership could not locate the VIN on their lot during a scheduled pickup. 

Multiple warning light activations (ABS, TCS, hill descent) diagnosed by mechanic as failed ABS module (combines electronic and hydraulic components) (PN: 68145835AE). I have been on a waiting list for a replacement part from Stellantis for almost a year. Numerous owners report online that this part is unavailable or no longer being manufactured. Stellantis has not publicly acknowledged the problem or provided a proposed solution or timeline. ABS is widely acknowledged as a key component of modern automobile safety systems. Stellantis's failure to provide replacement components for these modern vehicles places the driving public at unnecessary risk. A recommended resolution is that Stellantis provide NHTSA with a credible plan of action to begin providing replacements for this critical component (and other related part numbers).

THIS IS 2012 Jeep Wrangler its 14 years old and for 14 years the previous owner renewed the registration put insurance on it and it passed the emission tests despite the fact that it was recalled. Now the parts were in back order and they replaced my airbags but when the tow company went to the dealership to pick up my car the dealership wouldn’t release it This is absurd how does a 14 year old car go unnoticed that long. I had to stop driving the car for months because of this recall and the battery died you know a car can’t stay parked too long I took this recall seriously unlike Stellanis who murdered 29 people by refusing to flag these vin numbers to the DMV like the jeep I had and it’s sick how your agency has enabled this behavior truly sick

The contact owns a 2012 Jeep Wrangler. The contact stated that while driving at 20 MPH, the check engine warning light illuminated. The local dealer was contacted, but the vehicle was not diagnosed or repaired. The vehicle was taken to an independent mechanic, where a scan was completed, and diagnostic trouble codes for the Emissions, engine misfire, timing chain, and crank position sensor failures were displayed. The manufacturer was not contacted. The failure mileage was approximately 71,756.

My complaint is that I was sold a dangerously defective vehicle with a known, unrepaired “stop driving” airbag safety recall, was not warned about the deadly risk, and am now being told to move and tow the car in direct contradiction to official safety instructions. ### Factual background - The vehicle I purchased has a Takata‑type airbag safety recall that carries a formal “do not drive” or “stop driving” warning because the airbag can explode and kill or severely injure occupants, even in a minor crash.[1][2][3][4] - Federal safety authorities have confirmed that at least 28–29 people in the United States have been killed and more than 400 injured by exploding Takata airbag inflators.[3][4][5][1] - I received the recall notice about two months ago, but I was told the repair parts were back‑ordered, which delayed fixing the deadly defect through no fault of my own.[1][3] - During this delay, the vehicle’s battery became completely dead, and I am now being told by the recall and towing company that I must make sure the car is taken out of the garage, which would require entering and moving a vehicle I have been legally and explicitly told not to drive. ### Legal and safety concerns - Official guidance from the National Highway Traffic Safety Administration (NHTSA) and the manufacturer is that vehicles under this Takata “do not drive” recall must not be driven at all until the defective airbag is replaced, because even a minor collision can cause the inflator to explode and send metal shrapnel into the cabin.[2][4][3][1] - The instruction to move or drive the car out of the garage conflicts with this clear safety warning and effectively asks me to assume a risk that has already caused multiple deaths and serious injuries nationwide.[4][5][2][3][1] - Federal law prohibits franchised dealers from selling new vehicles with unrepaired safety recalls, and legal experts warn that selling used vehicles with undisclosed safety defects can expose sellers and dealers to

Dealer repair unavailable in local zip:99901. Require identification and shipment of part to be installed by certified mechanic or system access to report satisfactory repair has been conducted.

2012 Jeep Wrangler Sahara. Received Stop-Drive letter from Stellantis/FCA on Takata airbag recall—front airbags may explode in crash, sending metal shards. Letter says do not drive until fixed. Called hotline (833-585-0144) twice yesterday & today—no help. Dealer (Corwin Springfield) says call Chrysler. No tow arranged despite free towing advertised for Stop-Drive. No loaner or rental offered. Can't drive safely—PTSD makes group transport impossible. Have VA medical appointment March 2nd & lawyer meeting March 3rd. Can't afford rental for weeks (they say mid-March fix). Manufacturer failed to remedy timely—need tow to dealer + transport/loaner now.

ABS module failure C2200. Repair parts not available.

ABS system faile, There is no replacement part to correct the fault, and there is no replacement date, code C2200

The dash displayed multiple warning ICONS and I carried the Jeep to a mechanic. They discovered that the ABS Module, which is the anti braking system, had a fault error and needed to be replaced. After multiple attempts have found out that this particular ABS Module, OEM Part number (68145835AE) is no longer available by Jeep Chrysler and has not been available for the past few years. This means the Jeep is not safe to drive if the roads are wet or icy due to the possibility of loosing the brakes from skidding/loss of control of the vehicle.

ABS brake module (Part # 68145835AE) is a known defect on Jeep Wranglers 2012-2014. This part becomes defective, eliminating the ABS braking feature, also causing other transmission related problems. The real problem is Mopar support. Currently, NATIONALLY, this part is, and has been on back order (over 300 backorders) with no expectations of being available. I have been waiting for this part for over 6 months (no ABS) and problems with the vehicle have been escalating. This is a known problem, discussed on JEEP Forum.com, Mopar parts suppliers and among dealerships

ABS has gone out and there are no new repair parts available from Jeep

ABS module malfunction. This has been an ongoing problem for Jeep Wranglers of this year, previous and later. Jeep recalled other models for ABS module malfunctions. Being a retired auto worker am aware that same components are used on other models to defer manufacturing costs. Vehicle lot numbers do NOT isolate the problem. Bulk purchase of components should be checked per manufacturing date. I have taken my vehicle to dealer for diagnosis and they say the ABS module is bad, BUT part is on back order with no real time date ( could be 2 weeks or 6 months)for delivery. Jeep dealer wants me to pickup vehicle until part arrives. Driving vehicle under this condition could cause brakes to seize, not work at all, fire and/or a possibility of an accident! Jeep knows and has know this is a problem but never a recall on this model. Researching other Jeep owners and Jeep forums it is documented of this problem and the expense that an owner has to incur to get it resolved! Jeep has made no effort evidently to recognize this problem with the example being that parts are back ordered. Then again there is a real problem and the original part was junk but now the owner is stuck with the bill and all the safety issues because new parts are back ordered.

My Oil pump and oil sensor keep going out every 4,000 miles. I have already had to replace it once. I don’t want to have to do it again. Clearly something is causing this issue.

Having a hard time putting gas, I have to do it slowly so it can go in, the worst is when I put fuel a bit more fast it will throw gas out even if it ain't even close to half the tank.

THE 2012 Jeep 4 door Wrangler had the ABS Control Module internal error failure, this makes the car unsafe to drive. The dealer cannot get repair parts, the car is un-repaired since October 2025. Further, they cannot source the chips for the components, the make cannot provide a delivery date.(UNKNOWN when this will be rectified. Other years of this car have been recalled for this issue. This year has not yet. PLEASE Help us !)

The vehicle exhibits a persistent valvetrain ticking noise associated with the rocker/lifter/cam components of the 3.6L Pentastar V6. The engine makes a rhythmic metallic tapping at idle and during acceleration. The noise has progressively worsened, leading to rough idle and occasional misfires. This issue is documented in multiple Stellantis technical service bulletins (e.g., TSB 09-015-24 and TSB 09-011-25) which attribute the noise to hydraulic lash adjuster and cam/rocker wear. If unaddressed, the failure can cause camshaft damage, metal debris contamination, loss of power and potential engine stall, posing a safety risk. The vehicle is available for inspection. The problem has been confirmed by independent mechanics who recommend replacement of the rocker arms, lifters and camshaft to prevent catastrophic engine failure.

In 2020 I bought this Jeep, within the first 3 months I had to replace the TIPM, at $950.00, now 5 years later the same problem, the TIPM is having issues again. Causing the engine to overheat. Jeep is telling me this happens, not at $950 every 5 years, I was told there was a recall initially when they were new. There has to be some sort of recourse, you just can’t sell faulty parts and say it just happens!

After replacing right front speed sensor, ABS module shows malfunction and vehicle goes into limp mode. Replacement ABS modules are unavailable from mfg.

I was driving through a parking lot, I made a left turn and the airbag light lit up on the dashboard.Then, a chime sounded, like a low fuel chime or door open chime. I turned off the jeep and went inside the store, I then returned to my jeep, started it back up, and drove home. Every time I’m at a low speed, and make a left turn, that same chime sound starts to chime and the airbag light flickers. A scan detected the following: B1B06(1/3)Active B1CDC(3/3)Stored B1B56(2/3)Stored I checked for a recall, but can not find anything helpful.

Timing chain and misfire bank 1 and bank 2 crank shaft and crank sensor issues.

I am reporting a persistent and safety-relevant defect in my 2012 Jeep Wrangler with the 3.6L Pentastar engine. The vehicle is experiencing misfires on multiple cylinders, especially cylinders 1 and 5, triggering codes P0300, P0301, and P0305. These misfires result in loss of power, hesitation, and rough idle, creating serious safety concerns during acceleration or highway driving. Despite replacing spark plugs, ignition coils, the crankshaft position sensor, purge valve, and both oxygen sensors, the problem continues. The vehicle has just 83,000 miles and is currently at a certified third-party repair facility. Multiple mechanics believe the issue stems from known defects in the left (Bank 1) cylinder head or valve train components—an issue Chrysler previously acknowledged via TSBs and a 10yr/150k mile extended warranty on select VINs. I contacted Jeep Cares and requested goodwill support, but they refused to even discuss the issue because my Jeep is not at a dealership. This leaves owners like me with limited, expensive options despite being affected by a well-documented defect. Jeep forums and independent shops have seen widespread misfire problems on early 3.6L Pentastar engines, especially 2012-2013 models. I urge NHTSA to investigate this pattern of failure. The misfires impact driveability and safety, and the manufacturer has not offered sufficient resolution or consistent support to affected customers. I’m happy to provide additional information, documentation, or diagnostics.

The Air Bag warning light is one and won't go off.

The 2012 jeep jk wrangler has serious electrical issues. The jeep randomly stalls while driving and sometimes won’t start at all. Right before it stalls, every light on the dashboard flashes and continues to flash until the car dies. Replacing the battery doesn’t fix the issue. Numerous complaints about jeep wranglers TIPM issues have been ignored by authorities. I suppose people will have to die in a crash or spends thousands fixing the TIPM or electrical issues before getting relief.

Airbag light is on. Airbag sensor is out.

Engine spontaneously caught fire. It had been parked for hours before it happened. Everything under the hood was totaled

For more than one year I have problems with the Anti-Lock Brake System Module - Mopar part #(68145835AE). Every time I place an order it get canceled because Jeep and or the supplier have the part on back order. I wonder when the NHTSA is going to intervene with this company, before an tragedy happens and someone get kill because the Jeep don't brake like is suppose to be.

The contact owns a 2012 Jeep Wrangler. The contact stated that the air bag warning light had been illuminated. The vehicle was taken to an independent mechanic where it was scanned and diagnosed with DTC code: B1B02; for a failure with the driver’s side air bag. Additionally, the clock spring test had failed internally. The local dealer was contacted, but the vehicle was not diagnosed or repaired. The vehicle was not repaired. The contact stated that after further investigation the failure was linked to NHTSA Campaign Number: 13V176000 (Air Bags) however, the VIN was not included. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 169,051.

The airbag indicator illuminated, and upon getting a diagnostic inspection from the dealership, the issue is the clock spring that is faulty. The shroud is another price required for replacement.
