2012 Jeep Wrangler Unlimited problems

“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.”

“Revision 6 November 2019 Dealer Service Instructions for: Customer Satisfaction Notification V41Steering Damper 2018 - 2019 (JL) JeepWrangler vehicles front suspension steering damper on about 192,000 of the vehicles may not effectively damp oscillation of the steering system, resulting in a sustained shake or shimmy in the steering wheel. I have a 2012 Wrangler with the same issue - front-end shake/shimmy. My Mechanic said to replace the stabilizer with the next level-up heavier-duty stabilizer from Mopar. Why isn't my Jeep (JK Series) included in this recall? There aren't any of these stabilizers available at Mopar or online due to exceedingly high demand from vehicle owners. This should obviously be a recall.”

“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”

“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…”

“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…”
