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.

We were about an hour away from home (in the mountains) and our Jeep had been running fine. We had stopped for a while and when we got back to our Jeep and started it, just about every warning light on the dash board came on and wouldn-??t go off (the brake light, check engine, airbag, ABS, etc.) The middle of the dash was also flashing different messages-??-??service park assist and service power steering-??. We started to drive and the car was jerking really hard while it was shifting gears. We think it was getting stuck in a high gear because it would hardly drive after we stopped at a stoplights. We turned our hazards on and just tried to make it to an auto parts shop. Our windshield wipers were automatically coming on and the speedometer and RPM needle were both going up and down really quickly. We spent just shy of two long months without our Jeep while it was in the shop. The mechanic ultimately replaced the clock spring and the TPIM. Meanwhile, I joined a Jeep Grand Cherokee Facebook group and it seems like this is a pretty common issue in Jeep Grand Cherokees. It was a costly repair and was very difficult for us to go without our second car for two months. I really feel like this issue needs to be addressed by Jeep.

I was driving and the battery light came on with a chime, within seconds the car smelled hot, the air conditioning went out, road hazard lights on dash indicating flat tire came on, windshield wipers were going on and off at different speeds and windows were opening and closing and then did not work at all. I got the car into the driveway as I was en route to our home. As I got car to the driveway I lost all power. I had the same thing happen in 2019 - Report # 11255268. I do not know where to go to get the vehicle repaired or it the old recall will apply to this problem once again. Should I have the car towed to a dealer? I have my own private mechanic that addressed the problem in 2019. Please contact me asap. I don't know what the plan of action should be. Can I bring it to my own mechanic or does it need to go to a dealer. Please call or send me an e mail as soon as possible as I am without a vehicle. My number is 847-867-3921 or e mail me at kemahgal@aol.com. OR sherlumpkins@gmail.com. or use both e mails. Thank you!

There's a eecall for the fuel pump, that may cause my Jeep to stop all of a sudden when driving it. The recall has yet to have an answer as to when it will get fixed. I don't want my car to stall as um driving and cause an accident, the safety of my children is at risk. Need this to be fixed asap.

This is my third time experiencing this system failure. Each time while driving and the vehicle in motion, the truck shuts off. Each time this has almost caused an accident as I was turning onto a street. The first time it shut off in the middle of driving was as I easy slowing down to stop at a red light and lost all controls as the vehicle died. I did not accidentally touch anything. This is extremely dangerous and something needs to be done bout it asap. It turns off unwarranted while driving. I have to put the vehicle in park and press the start button to turn the vehicle back on. I do not know what part is causing this problem. It happens out of nowhere occasionally and not everyday either.

My Grand Cherokee has stalled several dozen times over the past few years and the dealer can't fix it. The car stalls when slowing to a stop or turning through an intersection but we can't duplicate the problem at the service center. The dealer kept the car for nearly a month trying to duplicate the problem but could not, but I have kept records over the past year of all stalls and the conditions and the only condition that remains constant is that I am quickly braking from 40 mph or faster or I am braking while turning. Initially it only occurred while turning left, but now it occurs while turning right and while braking quickly while going straight. I have been in several near misses due to losing power steering and brakes and I am to the point to where I can't allow anyone but me to drive the car due to the safety factor. Twice I almost hit a car while turning and once a big rig almost hit me in the side as the car stalled mid-intersection of a six lane highway. The car is still under Chrysler's warranty, and as noted, the dealer has tried to fix the problem, but has failed time after time. The problem has occurred dozens of times but the latest time was today, at which point I decided to submit this complaint. Although I can't duplicate the problem on demand, there are 3locations where it most often occurs, and it most often occurs in the morning. The first location is about 2.5 miles from my house, and the other two are 5 miles each from my house. Two of the three locations are at intersections with red lights, while the third is simply the location of where I work where it has stalled multiple times while just turning into the driveway. It also has stalled several times while coming home or just driving around or on vacation. Dealer has replaced fuel pump relay, wiring, and some emission control parts.

I was pulling into a parking spot and transitioning the vehicle to park when the vehicle accelerated. I had my foot pressed firmly on the brake but it did not stop and it went up and over a parking barrier into another parked vehicle.

My acc sensor will not connect therefore my cruise control does not work, leaving useless buttons on my steering wheel. We have no idea what is wrong with the whole system. Took it to the dealership and while they were doing recall work, they checked it. Said I would have to buy the $2,000+ acc unit and then it would probably be $1,000+ labor and then however much if they have to replace wires or anything else. I just want my cruise to work, I don't care if the distance part works. Warranty would not cover it and I'm sure I no longer have any factory warranty left on my vehicle.

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.

Vehicle randomly shuts off while driving. No indications of problem as far as warnings. Loses all engine power, power steering, power brakes. Happens when slowing. Once shifted to neutral or park, it will restart without issue. Intermittent dangerous problem. No faults active, no diagnosis to be found. Vehicle is up to date on recalls as far as we can tell. Concerns for safety are present. Vehicle currently has 128929 miles, but this has happened 3-4 times a year randomly since we purchased it at 33K in 2014.

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.

Vehicle stalls when applying brakes while decelerating. All power is lost and very difficult to steer or brake. The vehicle will restart when put back into park after drifting to a stop. This is a random problem that occurs 1-2 times every couple of weeks on average. The problem has been reported to Jeep and has been at the dealer several times but they cannot reproduce the problem and there are no engine codes being generated. This is a very dangerous hazard and I have simply been lucky I have not been in a serious accident yet as a result.
