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.

The camshaft has gone bad and unnatural wear to the lifters has caused the issue. Also, after researching the design of the engine, it is obvious that there is a design flaw. The camshaft does not receive sufficient oil in order to be lubricated due to its location in the engine. The vehicle only has 114,000 miles. It has been taken care of, and received the normal maintenance according to the owners manual. This particular version of the hemi engine has such failures well documented by multiple sources. Such an issue and malfunction attributes to premature engine failure. Such a significant engine design flaw can potentially cause injury to all occupants in the vehicle.

I just recently purchased this used 2012 Jeep Grand Cherokee. The problem I am experience, while driving at 74 mph the engine just shuts off. The vehicle would not restart for about 15 minutes. This has happened at least daily. The mechanic shop has checked the engine completely over. However they are stumped, The shop was able to repeat the problem but there are no codes. I know there was a recall on the fuel pump relay and then another on the relay. My mechanic has replaced the fuel pump relay but it still happens. I was reading in numerous blogs of this issue happening to many people. This past saturday night I was coming home from my second job when the car stalled out in the construction zone of 696 in Detroit, I can't tell you how many cars came close to killing me. This problem needs to be fixed by Jeep but there seems to be no movement, I'd hate to see people killed over this KNOWN issue. I know last Saturday night was the most fearful night of my life.

Was stopped at light and 2012 Jeep Cherokee lost all power and engine stalled. Lost lights, radio, heat and engine. It did restart after a minut or two. A week later, while driving, car began lagging/running rough. I felt I could not drive faster than 25 mph. Drove to Jeep dealer. Dealer is telling me it will cost more than $1500 to fix. I suspect this is a problem with the fuel pump relay....

After getting my car back from big o doge in Greenville sc I was on my way to work and stopped at a redlight when the light turned green my car just sat there and didn-??t move I pressed the gas but nothing it just revved up like it was in neutral pressed the gas to the floor nothing all of a sudden it was like it jumped and took off-??also did the same thing at a stop sign up hill and I had a car coming in the other lane as I was crossing the lane to get into the correct one-??.I had open recalls and set up for it to be checked when I arrived at the delarship they told me my recalls were closed. My car was not checked or repaired at the time how can you just cancel a recall/campaign after notification and claim parts aren-??t available but the car was never fixed? I called the delarship paid 400 for 2 diagnostics and they didn-??t put my trans cap back on so now they-??ve basically ruined my car and didn-??t fix NOTHING

Oil pressure sensor code P0522. The engine oil pressure sensor fails before and after oil changes. This causes the oil temperature to sporadically increase and decrease psi drastically from 20 to 110 psi and vice versa. This has been confirmed with multiple OBD2 sensors along with the check engine light constantly on.

I had purchased my 2012 Jeep Grand Cherokee 5.7 hemi in June 2019. Shortly thereafter, I was driving on the highway when the vehicle stalled out and the wheel became very hard to control. I managed to avoid causing a major accident and made it to the side of the highway where I then sat for over 4 hours stranded. After trying to start my Jeep it just started up out of the blue and I drove home. I was nervous to drive it but I had no other mode of transportation. Over the next few months it would increasingly stall out. Sometimes in mid turn, sometimes on the expressway and sometimes just not start at all. A recall came out and I was able to have the truck " repaired ". Not even a month later it started to do the same thing. Stalling in mid drive. not starting at all or starting in Neutral only. I took it to a different dealership and paid over 300$ for them to do a diagnosis. Their diagnosis consisted of a " walk around " and taking a video of the vehicle. What a waste of money. As I was going to leave the dealership the vehicle wouldn't start. Then after an hour it suddenly started. I had advised service about it and they said that I can leave the vehicle and have them look at it when they had time which they said would be 4 days from then. I said you just looked at it and did nothing and I had to pay 300$ for nothing to be diagnosed. I was able to get the car home and then the car didnt start for a week then started.. would drive it then stalled and have to have it towed home a couple of times. Now the truck has been sitting in my driveway not able to start at all. The fuel pump relay was supposed to be replaced by two recalls I believe. Nothing was fixed and infact it only had made it worse probably causing damage to the rest of my vehicle. I am lucky I didnt crash, or even kill someone because of this. It is extremely dangerous and to not have the part fixed correctly nor even remedied with a replacement of the TIPM is unbelievable.

The contact owns a 2012 Jeep Grand Cherokee. The contact stated while driving approximately 30 MPH, the check engine warning light illuminated. The contact had an emissions test scheduled and failed due to the check engine warning light. The contact stated that the vehicle engine was idling roughly. The contact had taken the vehicle to an independent mechanic, where it was diagnosed and determined that the number two cylinder had been misfiring and needed to be replaced. The independent mechanic referred the contact to a dealer where she had been advised that there had been a manufacturer recall associated with the VIN, however, the recall warranty had expired. The vehicle had not been repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 50,000.

Vehicle stalled without warning. No power whatsoever. Illuminated battery light came on. Noticed a burning odor coming from vehicle. Checked engine bay and noticed heavy smoke coming from alternator for a good 10 minutes. Vehicle would not take a jump nor could I put into gear. Battery is completely dead. PCM also seems to be fried. Will have to be towed to Dealership. Called Jeep costumer care and referenced the t36 recall but my vin does not fall under it even though vehicle fits EXACT description of recall. Also noticed that many others are have same problem with Jeep and them not expanding the recall to their vin. How terrible!! This could have easily been a fatal situation. Jeep needs to take some responsibility and action!

I have an on going issue with the vehicle stalling while slowing down for intersections, roundabouts and exit ramps. This has been happening since 2018. The vehicle traveling around 35-25 decelerating, the RPMs will just drop to zero and the engine will shut off. No warning lights, codes or indication I have lost power. Latest incident was on 1/14/22 in Mukwonago, WI after have only driven the vehicle for about 10 minutes. Coming from a 55 zone donw to a stop at an intersection the vehicle stalled with no warning around 30-25 MPH. 1/16/22 I was entering a roundabout and saw the RPMs dropping below idle to zero and was able to stop the stall by shifting the transmission into neutral. RPMs immediately went back to idle.

Jeep needs to correct this problem as it is very dangerous

The recall is V62 but after the recall was preformed the vehicle is doing the exact same thing. While slowing down and braking the vehicle will stall without warning, with the vehicle not running the steering and braking systems are disabled which makes getting out of danger impossible. The vehicle needs to come to a complete stop, be put in park, then be restarted. This will be the third time this happened. I had the recall done then I had to pay the second time to get it fixed and now I need to bring the vehicle back to the dealership for the same issue. Chrysler will take no responsibility for the issue.

My 2012 Jeep Grand Cherokee Overland with 5.7 hemi has had all recalls and the one for fuel pump relay V62/NHTSA 19V-813 completed Aug 2021. It is still shutting off while driving with no warning. This has occurred 3 times since August with the most recent being on Dec 26th 2021 in Leesburg Va. Stalls while driving causing the power steering to not function as well as the brakes. This engine power turns off randomly at around 10-15 mph (when making turns, stopping and/or decelerating) but there are no warning lights that appear on the dash. All electrical power to the car still functions and the engine stall is not noticeable until applying pressure to the brakes or trying to steer the wheels. Once i get the vehicle manually stopped and put the gear shift in Park, hit the start button, the vehicle starts up every time and will run for weeks or months before it happens again. Very dangerous. This recall needs to be reconsidered as this did not solve the issue. Matter of time before it is involved in a crash.. Taking to dealership tomorrow 27th or 28th.

I purchased my vehicle Aug., 16, 2018. While driving the vehicle will shut off and loss of all power occurs. It is extremely frightening and dangerous. I know there has been a recall for this issue and when I look up my vehicle under recalls it is showing that all recalls have been taken care of. The dealership has never solved the issue I have and it continues to happen. What do I do in a situation like this? This has been going on since I purchased the vehicle several times on several different occasions. After looking up the carfax report I've realized this vehicle has had a problem with shutting off while driving since it was new.

Lifter & camshaft failed while driving on the highway The engine response failed while driving & just about caused an a car pile up on the highway, all while dumping fuel out of exhaust! The dealer knows about the the flaw with the 100,000+ with the same issue, will not fix it unless owner pays over 4K+ & will not address the extremely hazardous issue. The independent Service place says it-€™s a flaw from the production & that Jeep knows but won-€™t resolve it, unless owner pays.
