CarComplaints.com 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.

My Jeep has shut off / stalled on me twice now since I have purchased it last month. This is an absolute random issue, and happens while driving. The engine will shut off with no warning, and you loose power steering and power brakes. Very scary, and a very serious and deadly condition. Jeep and Chrysler are no help. Was at the dealership for three days, and they said they can-€™t find the issue, and gave it back to me. Pathetic!

UNKNOWN: Fact: My 2012 Jeep Grand Cherokee Overland fuel pump relay can fail while driving and cause a vehicle crash without warning. This information was provided in December, 2019, in a letter/notice from FCA. The recall number is V62/NHTSA 19V-813. Replacements for this Fuel Pump Relay are being supplied to Dealerships at the rate of 1 per week. This is unnacceptable and is forcing owners of these vehicles to put their families at risk. I cancelled my, and my family's vacation because my dealership is unable to provide a fix for this fuel pump relay, actually the SECOND fix. The first was R09/NHTSA 14V- 115.

Received check engine light (cel) P006D while vehicle was in motion. Cause was a faulty oem filter housing w/ cooler 636463. Safety risk is while this error was activated no other engine problem would be reported to the driver. Replacement cost $953.76. Service station stated many of these failures are being reported at this time. Currently Jeep does not have a recall on this failure.

Engine light goes on blinks and car starts to shake had dealer look into engine. They stated the engine block needs replacement. This has been going on since I owned the Jeep. The car can stall at any minute and just shutoff. Driving on city streets engine light blinks for a few minutes the goes solid for a few days then goes off only to restart the process car always shakes and makes noises.

The V62 recall did not work for my Jeep. It was fine for about 3 mos (didn't stall while driving) and then it stalled exiting the highway. In the past year I've had the fuel pump replaced, multiple 'fixes' for this recall and it still stalls.

Despite recall V62 being 'fixed' by Jeep dealership, vehicle continues to stall while in motion. Often times while turning either on city streets or highway. After multiple stalls I started keeping a log of when and where they occur. This is extremely dangerous and has caused for some scary situation on the highway and approaching intersections. The recall fuel pump relay fix has not corrected the problem.

My Jeep has been stalling multiple times when trying to start it. One night when I tried to start it, it would not turn on. I brought it to the dealership and they changed the fuel relay on it, however I just brought it back 2 days ago for the same problem. They replaced it again, however when picking it up it stalled again.

I took my Jeep to have fuel pump relay and alternator recalls serviced at napleton Jeep in kissimmee fl and the car broke down a few days after being serviced, had the car towed to the dealership where they charged me $189 to say it was the starter that was bad and quoted me $800, I felt put off and got the car towed to a diff private owned shop for a second opinion, the mechanic did a full diagnosis and provided proof that the starter is good and its the alternator, stated that the dealership not only installed improperly but that the part is faulty, . ground wire was not connected to the engine and therefore it couldn't be started alternator charge wire installed in an incorrect position and tugging on harness and protective cover can't be placed over power wire alternator not charging and getting extremely hot, all of which should be covered under warranty, so I went back to the dealership and asked for the service manager, oscar, who told me he would not only not refund any money for the mis diagnosis but he would also charge me for any further repairs even tho the part that was installed two weeks ago is the one that has and issue and should one still under the same warranty. Then I was harassed by service manager who threatened violence on my family over the phone. The Jeep now even once repaired could have so many issues arise as well because of the negligence this dealership has shown, the have underqualified and unsupervised technicians doing jobs they are not ready to be doing alone. Now I worry for my safety and longevity of my vehicle. The dealership also left the car running the entire time they had it. So my battery was shot and it is brand new. I have all receipts and documents as well just your website isn't allowing to upload them all so I included a photo to show how negligent this dealership was.

The latest incident happened Sunday 11/29/20. Prior to this, the event has happened at least 4 other times. While driving at highway speed 55-70 and slowly coming down to a stop on a ramp or turning the vehicle while decreasing speed, the engine will stop running. No visual or auditory warnings happen, you're only aware when you feel the power steering has gone away, and the tachometer reads zero RPM. I have been able to safely pull off and stop in each event, the vehicle needs to be cycled off and then restarted. The safety concern is this event could happen into left turn across oncoming traffic with no ability to accelerate out of harms way.

On two or three occasions in the last year, when I go to start the engine, the engine cranks many times, but won't start. I would typically believe this to be a "no fuel to the engine" issue or "no spark", but once I'm able to stop the car from cranking (which has been an issue) and attempt to start the engine again, it does so without incident. It makes me think that there is an electrical issue in the ignition system. There is no rhyme or reason as to when this happens or may happen.

This vehicle has on at least four separate occasions in the last 2 years just simply stopped running. To be clear, each time I was in the middle of driving somewhere and the engine would just stop. Each time, I was driving somewhere locally and on city streets. The first few times this happened, I was either stopped at a stop sign, or stopped at a red traffic light, at which, I either "felt" the engine stop, or I realized it when I went to proceed after the stop and got no reaction from the car when I hit the gas and tried to proceed on my way. These times, I simply turned off the ignition, and started the engine again. I don't remember and didn't take note of whether all electrical had turned off or not. But the most recent time this happened was very concerning. It was July 10th, approximately 11pm, and I was driving on a local boulevard at approximately 40-45mph when, again, the engine just stopped. This of course, disabled power steering and power brakes. Headlights and radio continued to work. Thankfully, I was able to safely pull over and turn on my hazards. I then turned off the ignition, and was able to start the engine again. The car has not replicated the issue since then, but I have to consider this when I take my family for a drive/trip. I have to consider their safety, and the thought that it could just stop in the middle of a turn or at high speeds on the freeway, or both, is very concerning. The fact that the engine just stops, (and doesn't sputter or shudder or shake to a stop) makes me believe this is an electrical problem.

The engine light is illuminated so we took it for diagnosis to a Jeep/Chrysler dealership for diagnosis. The diagnosis for my vehicle is low compression in cylinders #1 and #2 causing a misfire. The code is P0302. The irony of this diagnosis is that Chrysler knows all about this problem and has issued a cylinder head extension warranty for only the left side of the engine. Meaning that Chrysler will repair the left side (under warranty) but will not warranty the right side of the engine that suffers from the same problem. Cylinder #1 is covered by the extended warranty 10 years 150,000 miles and cylinder #2 was covered under the original power train 5 years 100,000 miles and we are still under 100,000 miles on the vehicle. Unusual wear and failure in the upper cylinders and valves are pervasive problems with 2011-13 Jeep Grand Cherokee with this engine I was advised by the technician at larry miller Chrysler that lkq and C&K do not offer aftermarket engines for this make and model so the factory motor seems to be our only hope. We have submitted a claim to Chrysler Corp and am getting their "generic automatic email that states our clain has been closed". one representivae even asked us to submit the stamped work order and any receipts, which we did 10 days ago. Today we called to ask about our claim and are being told it has been closed and they have not goven us any explanation other than it is outside the warranty. How can 1 side of the engine be covered but the other side is not? we basically have to pay for a whole new engine and labor costs to the tune of $8,000. This vehicle has already had multiple recalls and repairs and we are devastated at this point because this engine issue is emotionally and financially ruining our family.

My wife was stranded when the engine stopped and will not restart. Mechanic made us aware he cannot fix as this is an issue under an open recall for the vehicle since November 2019. I called a Jeep service center who said they cannot apply the recall work because Jeep/Fiat haven't made the parts available. Meantime we now have a Jeep we still have to pay for even though it cannot be driven. This recall came out a year ago and I am told another year could pass before Jeep makes parts available to service centers. What in the meantime are impacted Jeep owners supposed to do, keep paying for vehicles that cannot be driven? two years being without a vehicle is completely unacceptable. (recall related incident) ts we had shut off the engine to refuel and the engine would not restart, stranding us. Our mechanic ruled out bad gas and indicated the tipm has malfunctioned. Recall 19V-813 addresses it (Jeep's recall for it is V62) but appears another year will pass before the recall can be done. That's a year after the recall was announced. Again, unacceptable.

My 2012jeep Grand Cherokee will stall as I'm coming to a stop. It doesn't alert with any codes when this happens. It is now doing this on a daily basis. The body shop informed me that a part is still not available for this issue. It stalled trining onto a on-ramp, while I was in a roundabout, as I approached a stop sign. It is happening at deceleration. No code is sent any time it stalls. The music is till playing, all lights are still on. I know it has stalled because the power steering is out and engine is off. I put the car in neutral press the break and started button to make it go again. Totally not safe while in a roundabout let alone anytime.

I was passing a slow moving truck on a 2 lane highway when my Jeep lost power for several seconds. I came very close to a head on collision. The Jeep has had a no start problem since I purchased it 5 years ago. It has been in dealership service departments multiple times for the issue with no resolution when still under warranty. All online research points to a defective tipm and there are related recalls. The current open safety recall is number V62 with fca for the fuel pump relay which is part of the tipm. The loss of power is one issue that can be caused by the faulty tipm, as well as the no start problem my Jeep has had the entire time I've owned it. I contacted fca recall assistance center and opened a case, informing them that I almost had a head on collision due to their defective product with an open recall. They told me there was nothing they could do but notify me when a fix was available. This recall was issue almost a year ago and involves life safety. I have no choice but to continue driving a vehicle that almost killed me 2 days ago because fca refuses to fix a defective part for several years.
