The vehicle will die while driving it, it is a automatic so you loose power steering power brakes and the engine is completely shut off you have to safely pull over and not get hit to put vehicle in park sometimes it starts in park, sometime it just turns over and you have to wait 10 to 15 minutes for vehicle to start. Dealer keeps telling me there is no issue with the vehicle, and they cannot replicate issue. I fear for me and my family's life every day in my jeep wrangler.

ABS, Traction control and Brake lights came on. Veh has 45000 miles on it. Was advised the ABS module is bad. Part is no where to be found, and no dealer can order it. Basically the vehicle braking system is questionable on the road without ABS or traction.

I recently purchased a 2012 Jeep Wrangler unlimited (VIN: [xxx]). within 1 month of taking possession of the vehicle, the car began to stall intermittently while driving. Specifically, the engine shuts off and the power steering and breaks deactivate. To state the obvious, this is a very dangerous condition, particularly as our family has three children under the age of six. To date, larry miller Jeep has been unable to diagnose the issue as no error codes appear. Looking online, this appears to be a known defect with Jeep of my model year (https://www.wranglerforum.com/threads/electrical-problem-shuts-off-while-driving.190041/) so I am surprised that Jeep has not issued a recall related to this problem given the dire potential consequences. I have escalated this matter to your customer care group, but I want to make sure fca has situational awareness of this situation as well.

On my way to work on city street, slight curve in road, it was raining. Cruise control set at 50mph. I heard the chime and glanced at the dashboard. Cruise control light was out, ABS light, anti-skid light and parking brake light were on. Touched the brake slightly and Jeep went into a skid. Luckily no one was next to me. Took it to my mechanic the next day and was told the ABS module had failed and needed to be replaced. This vehicle has less than 38000 miles on it.

Purchase 2012 Jeep Wrangler jku used. Parking brake would not hold vehicle when purchased. Every component in the parking brake schematic has been replaced with new. Parking brake properly adjusted twice, still unable to hold vehicle at 7 degree incline sloped driveway. Even tried over-tightening the star wheel adjuster for the brake pads, still does not hold vehicle. Conclusion, 2012 Jeep Wrangler jku is too heavy for the fca designed parking brake, this vehicle will create a crash when it moves out of a parking space into traffic because of under designed parking brake.

Emergency brake will not hold even after adjustment. I've installed new rear brake rotors and new emergency brake shoes. Adjusted the adjuster correctly and still the emergency brake will not hold. Design flaw in the emergency brake handle prevents it from engaging correctly. Weak spring not direct cable attachment. Never holds at all. Mechanic stated it has been redesigned due to this issue and entire brake must be replaced.

Stationary vehicle starts when I open the door without having key in ignition. Stationary vehicle engine fails to shut off when I turn off ignition and remove key. Anti-lock brake system locks up brakes while vehicle is standing still and will not move under any throttle amount because the brakes remain locked up. Vehicle factory alarm turns on and off randomly when drivers door is opened. Windows roll down by themselves while vehicle is turned off. Air conditioner blower (can't say if compressor keeps running or not) randomly shuts off while driving down the road and comes back on a couple of minutes later. Cruise control will not accept speed set but then turns 5 minutes later whether you wanted it to or not. Everything points to the tipm but even with 10's of thousands of complaints Fiat/Chrysler still insist there is no Wrangler tipm problem, and U.S. government oversight groups refuse to do anything about it. (when did this happen date is just the latest occurrence of an ongoing serious safety issue that Fiat/Chrysler refuses to acknowledge..

2012 Jeep Wrangler was completely stopped behind another vehicle. With no warning and while my foot was depressing the brake petal the Jeep began to accelerate forward. The brakes did not hold the vehicle and it proceeded forward and hit the vehicle in front.

The parking brake handle/ clutch assembly has been faulty on my vehicle from about 6 months after buying it new. It being a manual transmission has caused the vehicle to roll away on several instances. I have ordered a new parking brake assembly to replace the original oe unit to try and fix the problem. Yes the parking brake shoes have been adjusted multiple times. This is an issue with the cable tension system.

Parking break will not hold. Have had the parking break shoes replaced and adjusted but still will roll slowly if not on a flat surface. Mine has a manuel transmission so I have to leave it in gear to keep it from rolling. I have spoken with several other Jeep owners and they say this is a common Jeep problem but I fill like this should be covered under a recall. The clutch also is in need of replacement after only 74,000 miles of driving. Has been like this since I bought it in April 2017.

Driving at freeway speeds some bumps or uneven surface cause car to lurch. Engine shuts down to no throttle; this is very disconcerting for driver. Happens 2-3 times a month on such roads. I suspect the skid control. When that is turned off it does not do it. Jeep needs to fix this. Car recovers after 2-3 seconds but in meantime this could easily cause car behind to hit you. So far have been lucky this did not happen.

  • Automatic transmission
  • 72,107 miles
The contact owns a 2012 Jeep Wrangler. While driving 70 mph, the front track bar bracket to the front axle fractured without warning. The failure caused a loss of power steering function because the axle welds separated and became undone. In addition the brakes malfunctioned within the electronic stability control system and the ABS. The front axle was replaced. The manufacturer was made aware of the failure. The failure mileage was 72,107. Updated 04/28/17

After a 30 mile trip, I discovered that the left front brake of my Jeep Wrangler was overheated, confirmed by a distinct burning smell, an extremely hot left front wheel, and a pulling sensation when brakes were applied. The next day, I took the vehicle to an authorized Jeep dealer for diagnosis and repair. I was told that both front brake calipers were "bad", and needed replacing. The vehicle has only 69,000 miles on the odometer. My 2012 Dodge journey had the exact same problem with the rear brake caliper.

Wrangler

  • 15,000 miles
The left rear brake caliper engages randomly. When engaged the vehicle is slowed somewhat. Sometimes there will be coming off the disc pads. I have noticed that I can clear the condition by following the hill start assist on/off procedure. A mechanic told me this is a computer failure and he can fix it for $1300. I think it is a serious safety issue.

Wrangler

  • 56,000 miles
Jeep Wrangler unlimited rolled away on slight incline (< 5 degrees) with parking brake engaged and driver out of vehicle. Driver had to reach inside the rolling vehicle to press the hydraulic brake pedal by hand to bring the vehicle to a stop. If driver was not next to vehicle when incident happened, vehicle would have likely rolled out into traffic. Vehicle failed state inspection in April 2016 due to parking brake not holding. Parking brake was adjusted and passed inspection, but failed within a month.
