Notes: The 2012 Grand Cherokee hasn't seen the same complaint volume as the 2011, at least not yet.

It's worth noting both model years are part of a class-action lawsuit that focuses on a defective TIPM and a long wait for replacement parts.

The 2012 also received national attention after it failed a Swedish Magazine's "moose test". The test measures a vehicle's ability to swerve out of the way of an obstacle you wouldn't want to hit while driving down the road ... like a moose.

I was driving on the highway on 7/21/19 and my 2012 Jeep Grand Cherokee's engine seized. The car had to be towed and now Jeep has a 2 month waiting list for the hemi motor (which apparently this is a known problem for - that is why the waiting list is so long). It will be over $8000 to fix and I still owe on the loan for the car that I have had less than 3 years. If hemi motors are a problem, Jeep should make them with V6 not the hemi V8 motors. There is no recall for this as of now. I am stuck without a vehicle to get to work and a large loan for a useless Jeep that I can't drive. It has 90,000 miles on it. Why is Jeep allowed to continue to make these if they are such issues. Why is there not a recall on hemi engines in Jeep? then when you try to call Jeep corporate they claim they return calls once a week (which they don't) and the customer service reps told me "thing happen". this is a terrible way of doing business and as a Jeep owner for many many years I will never buy a Jeep again. Hopefully this happens enough that they will need to do a recall and I can recoup some of my money back.

I have less than 76K miles on my Jeep. I have been the only owner, taking exceptional care of my Jeep, always getting oil changes on time and maintenance with very few city miles on my Jeep and I am having to pay 10K for a new motor and camshaft.

I recently purchased this vehicle and it completely shuts off unexpectedly. When it does it affects both the braking and the steering. The first time I was stopped at a light and was an easy fix but the 2nd time I was getting off an exit around 50 mph. I have young children and now I am scared to drive them around in it. I know in not the only one this is happens, there's complaints all over the internet. There should be a recall before someone dies.

My vehicle has decided to start bogging around 35mph. It has continually done this for a week and has decided to start driving horrible. It does not drive like it has been. We are going to check what the problem might be Sunday (7/7/2019) and attempt to fix. My Jeep is no longer covered under warranty.

My engine light has decided to light up in my Jeep randomly one day after starting it. After scanning it, it shows code P0522. The research I have done has shown it usually shows the oil light when it is that code. So as a result, I have had my oil changed again and I have ordered a oil pressure sensor/sender hoping that will fix all my problems which will be installed next Sunday (7/7/2019). I also had to change the water pump because it had a crack in it, the thermostat just for precautionary measures, and the belt because it had a tear in it about half the size of the width. All of this to try to figure out the problem with the engine light and the scanner showing the code P0522. So we will see if that actually fixes the problem.

Engine stalls for no reason under braking and deceleration. Happens more often when braking and turning. Loss of power steering when it happens. Does not happen frequently, more often in the cold when the car has been started. Cant replicate it when car is hot. Dangerous when it has happened on exit ramps as car has to be controlled with no power steering and car has to come to a complete stop, put in park where it has always restarted. People behind me not happy when stopping on exit ramps. Have brought to dealer after it has happened and the car has not thrown any codes. There is not real pattern to this stalling, but, having to stop the car to restart it posses a danger of getting rear ended. Happens at speeds between 30 to 60. Happens most frequently in rotaries (roundabouts) when slowing down to enter.

Braking from ~35mph to make a right turn at traffic lights the car just stalls without any indication of issue. No power steering or brakes. All electronics still functional. Coast to to a stop at the side of the road, fighting the heavy steering to avoid cars in the on coming lane, place in park press brake pedal and hit start button, and the car starts right up. Drive to dealership (prime Jeep in saco, Maine). Steering module clock spring was replaced last year (August 2018) as the supposed cause for this exact stalling problem that was happening last year.
