2012 Jeep Grand Cherokee Engine Problems

Two similar incidents to report during week of Dec 15th 2025 on surface streets: Was driving 25 mph when 2012 Jeep Grand Cherokee just came to a complete stop -- without any warning signs of a problem. Vehicle stalled with no engine power and loss of power steering. I could not steer the vehicle to the side of the road. Was just stuck. The emergency lights did work. I put the vehicle in park and restarted the engine after about 30 seconds. The vehicle drove normally therafter. THIS COULD HAVE BEEN CATASTROPHIC IS IF I HAD BEEN ON A MAJOR HIGHWAY WITH TRAFFIC. This same stalling of the vehicle with no power or steering ability has happened 2 other times before earlier in 2025. The Dealer insists there is no recall, but this looks like the same problem that this Jeep had in 2019 when the dealer replace the fuel pump relay as part of a previous recall. Obviously that recall was not effective.

In August 2025 my 2012 Jeep Grand Cherokee Laredo lost engine power and stalled while driving 15 mph. There was no warning. I was able to restart the car and drive. Then while driving in traffic at 45 mph on 18 Oct 2025, my Jeep abruptly lost engine power and stopped, putting my safety and the safety of my passenger at great risk as I had several cars behind me. Again, the Jeep stalled without warning. I was able to put my emergency warning lights on, then after 30 seconds, I put the car in park and restarted the engine with no problem. The Jeep drove normally. This unexpected loss of power while driving at speed in traffic on Hwy 431 could have been catastrophic. This incident appears to be linked to two previous Fuel Pump Relay recalls, the most recent being V62/NHTSA 19V-813. My Jeep was repaired by the Jeep dealer under both of these recalls which were prompted by no-start conditions and ENGINE STALL CONDITIONS. It appears the FCA repair has been ineffective as my Jeep has experienced two engine stalls while driving and does have intermittant problems with start up. This most recent problem has not yet been confirmed by a dealer as the Jeep Dealer cannot see my vehicle for another 2 weeks, which puts my safety at risk. There were no warning lamps or messages before the abrupt engine stalls while driving. However, for the past 6 months, I had had intermittant instances of the car not starting immediately, particularly in the morning. I would turn the key fob a few times before my Jeep would start. But it always started.

My vehicle stalls a lot when driving. At first i thought it was an issue with the tire alignment but i was told by a mechanic that i had good alignment. My car stalls and shakes a lot while speeding up in the highway. I honestly feel unsafe at this point because its gotten worse in a short amount of time. My seatbelts are lose and useless. I love my car but i may change it for a safer option. It is definitely dangerous to go anywhere but it is my only car i have.

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.

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.

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.

I did the fuel pump relay recall and the problem that it was supposed to fix isn’t fixed.I’ll be driving along and the jeep will stall as I’m driving when turning off the highway and exit ,the power steering and power brakes cut out I pull over put the jeep in park and it starts right up.Then it’s ok for a couple of weeks and it happens again no engine light or close faults . Jeep needs to correct this problem as it is very dangerous

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 went to the dealership and was informed the fuel pump relay recall is not available. My Jeep Has been misfiring, stalling, vibrating, and I am smelling gas fumes when I drive.

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.

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.

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.

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.

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.
