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.

Report from diagnostic service 1-9-2023 cylinder head - has premature failure of valve guides and cylinder head replacement is required for repair. Yes, Jeep extended the warranty but if your vehicle did not show problems they would not fix it, but they did learn and knew at the point the seriousness of the problem and put an end date on the fix. Our vehicle outlasted their warranty by 30,000 but now is undrivable. Before anything serious happens as the driver drives on longer drives we have grounded the vehicle.

While interstate driving the vehicle dash dinged, I looked down to find the ABS, Traction Control and Emergency Brake came on. I immediately pulled off the interstate for a visual inspection of the breaks and brake fluid but did not see any glaring issues. I took the vehicle to a local shop, they read the code (C2200) and advised I needed a new ABS Control Module (Mopar Part #68145835AE). The local shop advised the Module is difficult to find, but they found one and would complete the work for $2,400.00 ($1,500 of which was for the ABS Module part). I called a local Chrystler, dodge, Jeep (Lou Fusz) dealer in O'Fallon to price verify the part. I scheduled an appointment for three weeks out. They also confirmed the code and need to replace the ABS Module for $1,500.00 ($881.00 of which was for the ABS Module part); HOWEVER, Jeep-Mopar told the dealership that the part is not available until March 20 of 2024 which would leave me with two options. 1) Sell the vehicle to the dealer; however, their offer took advantage of the ABS issue and was extremely low 2) Wait and drive the faulty vehicle Driving the Jeep with a faulty ABS Module may jeopardize critical systems, resulting in poor braking performance and potentially create a very dangerous or deadly situation. A search of this issue online in Jeep Forums has shown mass number of similar issues and others experiencing the same part deadly; meaning there are an untold number of jeeps driving with a faulty ABS Module. I pled to the NHTSA to please investigate and pressure Jeep to issue a Recall to ensure safety.

In my 2012 Jeep I had to replace the engine and catalytic converters. The engine number 3 cylinder failed due to excessive ware causing lower compression. After the engine (long block) was replaced, one of the cylinders was miss firing. This miss firing was traced to micro cracks in the plastic/composite intake manifold (original and not part of the engine replacement). Because these micro cracks changed the fuel air ratio on specific cylinders by leaning out the cylinders near the cracks this lean mixture would cause the affected cylinders to run hot that would lead to both the excessive ware on the one cylinder and would comprise the catalytic converters. Because this change in fuel air mixture was caused by the intake manifold and Jeep does not have any inspection requirements or methods for this item and even after the Jeep Dealer did a full diagnosis using their factory specified equipment the issue with the manifold was not found. My local AMMCO shop found the cracking in the manifold that was the route cause of the problem.

Jeep Wrangler 3.6 liter 90k miles lifter making loud noise. Seems you had a recall about this on the 2012 and guess I missed out

Clockspring failed causing airbag to malfunction. Jeep dealer ordered a replacement in April 2023 and still has not received the part(even though they have one in stock the manufacturer will not allow them to use and install the stock clockspring). We have been forced to drive the vehicle without an operating clockspring which creates a major safety hazard since the airbags may not deploy on impact.

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.

When the fuel vents on the top of the fuel cell get old, they are extremally brittle. Washboard roads or a pot hole can jar the fuel tank breaking the connectors that go to the emissions system and the rollover valve. If any of these plastic pieces break, there is a chance for fueling problems and effects the drivability of the vehicle. The 3 connector vent is a non-serviceable part, requiring the gas tank to be replaced. The replacement has the same plastic connectors, leaving the possibility for breakage. These connectors breaking can lead to a multitude of issues, including but not limited to fuel spills while filling, leaking fuel from hoses. I have had 2 tanks in my 2012 jku have this issue and a quick search on jeep forums will show that this is not an isolated problem.

I have experienced on a number of occasions, when traveling on the highway at speeds greater than 60 MPH and the vehicle his a bump in the road (expansion joint, pothole, etc), the vehicle begins to bounce uncontrollably. The steering wheel vibrates uncontrollably and it feels like the front end of the vehicle is bouncing on the highway. Its doesn't stop until you slow the vehicle down below 60 mph or so.
