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.

Grand Cherokee

  • 85,000 miles


Engine shuts off while driving, I was getting off the highway slowing down from a high rate of speed and my engine just shut off. I D id not even know the engine was off until I tried to turn and had no power steering or brakes. There was no warning lights no check engine light. All the lights and radio was still on. I had to put my Jeep in park then start it again and it started right up. It has happened twice in one week. I am terrified while driving now that it is going to happen again.

Starting issues, starts up and quickly cuts off. All lights and power are on. Plenty of fuel in tank but not overfilled. I think it is the fuel injection area. I worry it will just cut off due to that while driving. This has happened at least 3 times in the past 3 weeks, it is becoming more frequent.

Engine stalls while driving without warning. This started in November 2018 and has happened 5 times since. Have taken it to 3 different repair shops and still no resolution. There was a recall back in 2015 #15V-115 to fix the fuel pump relay which could cause this to happen. Service was done per the recall. Have an active case with Jeep (Fiat) but they have been no help and keep sending us the Jeep dealer. Diagnostics have been done 3 times to no avail. This is a significant safety issue as the vehicle dies while driving and the steering locks up as well as the brakes. Each time this happens the vehicle is in motion going about 40mph. Has happened while going straight and while turning. The radio stays on and no warning lights appear on the dashboard.

Takata recall while I'm driving the vehicle it will shut off. I will put it in park and it starts back up. This is unsafe because I can be driving in traffic or be in an intersection and it just shuts off. I've taken it to have a mechanic look for any readings and nothing is coming up. It also shuts off while trying to start the vehicle up for the first time. It takes several attempts, again nothing coming up when taken to the mechanic.this has been going on for almost a year.

Yesterday my Jeep engine turned off twice while driving on city roads. This happened in the morning on my way to work and at night on my way home from dinner. Luckily this happened on city roads either before getting on the highway or after getting off the highway, as I take the highway daily for work. Conincidentslly both instances happened while attempting to turn right. I did not hear the engine turn off while driving, but noticed because as I was attempting to turn there was no power steering. The radio, dash and interior lights never flickered or turned off when the ingine stalled. Again, luckily I was not at a high speed when this happened and put on my hazards and was able to slowly come to a stop with the brakes but they were very slow to react. I put the car back in park and started it right up both times. Very scary experience to have the engine just shut off in the middle of traffic and panic to avoid an accident from occurring.

I bought this vehicle used & no problems until the recalls come rolling in but had a cylinder 2 misfire at 132,000 miles ok contacted dealership & it was fixed, but found out this was the 2nd time this has happened amongst finding out the whole engine had to be replaced from the factory. I¿M now 161,334 miles & have a cylinder 2 misfire again. If it fails compression test again this will be a 3rd time the head has failed & I¿M past Jeep's extended warranty to cover it. Apparently Jeep has not fixed their flaw. It spits an sputters, idles rough sometimes & I always do my maintenance when it's needed. It does it when I¿M mostly parked but I can feel it when I¿M stopped & idling.

When slowing the vehicle it will just silently shuts off. This happens usually at the same 5 places, 3 of them when slowing to make a right hand turn in an S turn and the other 2 going straight slowing to stop to make a left turn across traffic. I feel like it's a combination of braking, steering wheel and when its shifting into 1st since I'm either in a stopping situation or S turn situation. When this happens I loose steering and brakes causing me to go into the opposite lane of travel head on. There have been recalls on the alternator for my vehicle but mine has never been included. There has been a recall for a sensor that has been completed but did not solve the problem. This is a serious issue, my chance for a head on collision is very very scary. This happens about 6-10 times a week.

The truck continues to stall while operating and does not turn over when trying to restart. This prevents a quick reaction to being stalled when slowing to enter or exit at an intersection. On most occasions, the car will not start and continues to crank when either using the push start, manual key fob, or auto start. It cannot be moved once stalled. If you attempt to restart too quickly or after several attempts, it will flood. This same issue was included in a previous recall for the fuel pump relay. However, it did not resolve the issue. The same behavior is experienced and is very dangerous. To provide history of failed recalls, the brake shield recall was corrected by two seperate recalls and was also a very dangerous safety issue that prevents driver control over the vehicle when stopping. The stalling occurs when coming to a stop or stopping, and when performing strong turns. These types of turns are done frequently at intersections with on coming traffic. It is very dangerous because you don't even have the ability to restart the vehicle to escape the danger.

1. Jeep dies for no reason when decelerating it happens at highway speeds when taking the foot of the gas it last happened on highway 1 on a big curve, steering and brakes lost power on a cliff side road.(scared me and the family 1/2 to death) it has happened on the dumbarton bridge in commute traffic it also happens when decelerating on off ramps or coasting to stop lights. You need to completely stop the car put it in park and press on the brake to restart it. This in traffic is also dangerous Jeep says 10 things may cause it and they will not fix try any of then because they cannot pinpoint which one it is. 2. cruise control slams on the breaks for no reason. Another dangerous problem no cars in front of me, open highway, no overhead bridges or guard rails in sight and the brakes slam on.

Algunos de los motores de los vehÍculos 3.6 vvt pentastar Jeep gran cheroke presentan un defecto de fabricaciÓN en la cual SE identifico en un 0.5 % de la fabricaciÓN entre 2011 Y 2012 una falla en la culata lado izquierdo lo cual produce fallos de encendido con los CÓdigos P0304 -P0302 -P0306 Y P0300 fallos de encendido los cuales pese a tratarse de reparar estos CÓdigos no SE pueden reparar por que la Única manera de solucionar ES cambio de la culata lado izquierdo hecho que crhysler lo reconoce en un boletÍN de servicio del aÑO 2014 boletÍN de servicio del aÑO 2014 NÚmero 09-002-14 rev.B donde lo especifican claramente Y ademas extienden la garantÍa a 10 aÑos O 240000 km. Siendo el caso de mi vehÍculo que presenta esta falla por lo que segÚN mi garantÍa (warranty repor for sud America ) la tengo pendiente con el CÓdigo (X56 ) 3.6L left cilinder head extendida por 10 aÑos O 239,850 kmsy mala combustiÓN de gasolina que la bota cruda Y esto produce la falla del catalizador por lo cual las emisiones de gases al ambiente son muy TÓxicos lo cual daÑa el medio ambiente. Mi vehÍculo ha sido revisado por el concesionario en peru SE han hecho las pruebas correspondientes Y si van a asumir la reparaciÓN de acuerdo a la garantÍa pero ES el caso que la central de eeuu. Indicaron que no hay stock del repuesto hay lista de espera de mas de 120 casos en espera mientras tanto los consumidores nos vemos agravados con el exceso de consumo de combustible Y el ecosistema del planeta al tacho por las emisiones contaminantes. ES increÍble que tenga 2 meses en espera de la auto parte que por derecho deben de reparar ya que ES una falla de fabricaciÓN Y ellos la reconocen. Y no dar respuestas sin fecha mientras el medio ambiente sufre la contaminaciÓN sin retorno. ES U claro atentado contra el medio ambiente

Vehicle in motion, but decelerating from higher speed to a stop or lower speed. Engine shuts off. No warning/dash lights come on everything else (radio, lights) continue to work. The only way to know the engine is no longer running is the power steering and power brakes don't work and the RPM on the tachometer go to zero. Car typically will re-start with no issue, but will almost immediately stop again. When the car sits for about 15-20 minutes, it'll start right up and drive fine. There has not been a pattern, other than slowing down. It's stalled on me the following times and situations: * slowing down to turn right off the highway - was raining, started right up after stall ran fine (2014) * slowing down to a complete stop at an intersection, would restart, but not stay running. Waited 20 minutes for towtruck and the vehicle started right up. (2016) * slowing to a stop for light in town, started right up, but would not remain running, waited 20 minutes ran fine (2016) * stalled in stopped traffic. Started right up was able to drive to a parking lot but stalled again and would not restart for 15-20 minutes. Ran fine once started again. (2017) * stalled in stop and go traffic on I-95 in philadelphia. Started right up again, but had to wait 20 minutes for it to remain running (03/2018) * stalled when coming to a stop for stop sign. Wouldn't start right up. Had to wait 15-20 minutes then it started and ran fine. (09/29/2018) have taken to the Jeep dealer on the three earlier occasions, however, they indicate that they are unable to replicate the situation and there are no engine codes to review - therefore they are unable to correct the situation. So I have been driving the vehicle as is, but after the last two times of this occurring I must remedy the issue. Assistance will be greatly appreciated.

I have owned this vehicle for 3 years, and in that time it has randomly lost all power while driving 5 different times, making it hard to turn off the road. I have to pull over and restart the vehicle. There is no warning, it just dies. I am not finding a recall concerning this, but there should be. I have read several other complaints about the same issue.
