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 Sweedish 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.

Grand Cherokee

  • 101,000 miles


Car lost all power for steering and braking. Car stalled. Was at low speed 5-8mph turning to the right into a gas station driveway from busy roadway of speeds of 55mph. Car went straight and rolled to a stop. Grateful was parking lot and ditch in front of me and not the gas pumps or another vehicle as I had no control of the car stopping. I have twice had car to dealer for car going into limp mode. Both in year 2016. Same cylanoid each time.

Alternator failed while going down the freeway at 65 mpg, resulting in loss of steering and braking. Alternator is 180 amp model. Vehicle has only 80,384 miles. Alternator failure occurred without any warning, and resulted in battery failure as well. Total cost for two components: $900 plus labor through dealership.

Alternator gone with low mileage 3.6 engine 160 amp alternator. Manufacture said they had a re-call P60 but my body style and VIN. # didn't match. Same eng. And alternator on the Grand Cherokee that were recalled makes no sense what that alternator is on. A bad alternator is bad alternator. Vehicle was in motion when a wining noise and battery light came on, smelt hot.

Car started normally however, once I began driving, a number of diagnostics errors were displayed on the screen. I started to smell as though something was burning so I returned home. A few minutes after that, the entire car went dead. No power at all. I could not even lock the door. I see that there was a recall P60 / NHTSA 14V-634 related to the alternator and the description of events that could occur with that, was pretty close to what I experienced this morning. However, when I researched this with fca, I was told that my VIN was not a part of that recall. So now, I am thinking that I may have this defective equipment in my vehicle. I have to have the car towed to a local dealership for a diagnostic review but over the phone, the service rep believed that it sounds like an alternator/battery issue. I have also read numerous complaints from other Jeep owners about similar problems. I want to be covered in case this turns out to be an issue where my vehicle should have been included in the alternator recall but was not. I was lucky that the failure occurred before I got away from my home and on the freeway.

Grand Cherokee 4WD 8-cyl

  • 86,000 miles
Within the span of approximately 15 months, the engine has randomly turned off 8 times in the middle of driving. When this occurs, the car loses power steering and braking, making it difficult to control, aside from the fact that the car can not safely be moved to a safe emergency stop location. The car has been to the dealership numerous times, but with no solution. The dealer has performed all recalls and software updates, but these have not solved the problem. The dealer has stated that they cannot replicate the problem, so therefore cannot fix it. Chrysler customer care was contacted and a case manager was assigned to the case. The case manager instructed the dealership to drive the car, which they had done before, to try to replicate the problem. They were unable to do so and the case manager has stated that there is nothing that can be done if the problem cannot be replicated. When asked what to do in the event the vehicle causes an accident, the case manager stated to contact him at that point and he will take the case "to the next level". in short, the car must be involved in an accident before Chrysler is willing to do anything. At this point, we are not comfortable driving this car for which we are paying a lot of money and are not being offered any solutions.

NHTSA campaign number: 14V634000 / Chrysler recall P60 already exists but that is for 160 amp mine is 180 amp, I think that is the only difference. My Jeep died and would not start up again. All power was lost 100%, luckily my family and I were stopped at a gas station getting sodas. It sounds exactly like the same issue of the recall that is already out but also effects my Jeep with the 180 amp alternator. According to Chrysler that is the only difference in the two models. Mine is a 2012 Jeep Grand Cherokee with a 3.6L

Grand Cherokee 4WD 8-cyl

  • 94,000 miles
I have a 2012 Jeep Grand Cherokee limited, 5.7L engine. Purchased the vehicle used. At approximately 60,000 miles (2015) the Jeep begin to randomly stall while driving. It always happened within 10 minutes of leaving my house. Fuel levels good, didn't matter if turning left or right. Vehicle stalled, causing steering to lock. Almost in 3 accidents. Only remedy was to put it in park, Jeep would start right back up. This happened in June, August and October. After October stall, I took to the Jeep dealership. The dealership couldn't find anything unusual, and replaced the battery. The trailer taillights were not working and they recommend replace tipm. Things were fine until September 2016. On Sept 2 Jeep stalls turning right, full tank of gas. On Sept 6 - stalls slightly turning into suicide lane. Back to dealership. Dealership has it from 9/7-9-9. can't replicate it, and no errors come up. They do replace recall sun visors. Sept 18 - stalls going straight on road. Again, this is in the morning, and within 10 minutes of leaving my house. Saturday Oct 14. Jeep stalls again around noon time. Hadn't driven it since Friday 1pm, the day before. Full tank of gas. Died while slowing down towards a red light, going straight. Almost rear ended as a result. The dealership cant diagnose one thing that happens randomly. There is a plethora of complaints online regarding the tipm and alternator in this Jeep. My VIN isn't covered by the recalls, but it sounds like a tipm would remedy the situation. This vehicle is unsafe to drive, and Chrysler isn't helping.

When slowing down or coming to a stop, the vehicle's engine will turn off and power steering will not work. In order to start the vehicle again, I need to completely stop, put it in park and start the engine. This has happened on the street and freeway. It does not happen constantly. I have had times where it happens 2 days in a row, once a week, and once a month. I have taken the vehicle to a dealer a few times already, but they have not been able figure out what the issue is. After having the vehicle at the dealer for over 1 month, I spoke to a senior technician that works at the dealer and he said it is a known issue. He told me that vehicles with the 5.7L engine and the push to start button have been having this issue and the issue starts around 30,000 to 50,000 miles and they are not sure what is causing the problem or how to fix it.

Unexpected stall while driving. Happened twice this week Monday 4/25 while turning and 4/28/16 while driving in a 45 mph road (grand river, farmington hills). This touch has been previously serviced by dealer for recall notice and has not helped the issue at all!

About a month after purchasing my used Jeep, I was coming to a stop on a city street and my Jeep powered off completely. After taking the Jeep in to the dealership they fixed the fuel pump relay, which was recalled, and sent me on my way. Since then my Jeep has powered off 5 times (once while entering the highway, twice while exiting the highway, once while making a U-turn under the highway and once on a city street) each time while braking. I've had no power brakes or steering each time.

Grand Cherokee

  • 42,000 miles
On the first of March, my wife and daughter were about to start their day in the usual way. She opened the garage door and used her key fob to remote start our 2012 Jeep gc limited ( around 42K miles) ( factory installed remote starter) she walked away for less than 4 minutes and returned to see smoke coming from front passenger side of Jeep. She called for me, and pushed the aux button to be sure the vehicle was off. I came running and despite my attempts to open the hood and beat back what quickly escalated into open flames I retreated to ensure my family's safety and to be sure the emergency responders were called. Thankfully I was able to remove some potential fuel for the fire by removing our second car from the garage (also a Chrysler) and securing the door between the house and garage. Luck intervened when the flames destroyed the garage door assembly causing the garage door to fall and help remove some oxygen from the fire. Eventually first responders arrived and were able to knock down the fire with foam. Later the firemen pushed the Jeep into the driveway to ensure it was doused. Though the remote start may not be directly responsible for whatever arc sparked the fire, it's my belief that its use contributed directly to the conditions that conflagrated the situation. If the wiring harness is otherwise suspect I would not be surprised considering recent revelations on related models. The vehicle was just removed from the site today 3/9/2016 to copart facility, by insurance company for further investigation into the source of the fire.
