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.

Grand Cherokee Laredo 3.6L

  • Automatic transmission
  • 84,400 miles

A D V E R T I S E M E N T S

Driving in rush hour traffic on the DC beltway, the battery light came on. About 5 minutes later ac cut off, lights on dash started flashing, wipers came on (very slow) and then Jeep cut out completely. Had to get out and push car off of I95 - again in RUSH HOUR TRAFFIC. Had it towed to a local shop owner who I was familiar with but called Jeep since I have the extended warranty. Jeep (Mopar) told me it had to go to a Chrysler/Jeep service department for it to be covered. Called 2 local Jeep service departments and BOTH could not look at my car for at least 1 week. Mopar agent said I could get it fixed at an independent mechanic and I could POTENTIONALLY get reimbursed. What a crock of crap. Ended up getting it fixed at independent mechanic for $1200, went to pick it up and 10 minutes down the road the battery light came on again!! Took it back and he is currently working on replacing the alternator thinking it may be bad (not charging). I'm doubting that now after reading other complaints. Thank goodness I purchased the extended warranty but it does seem that this is happening quite frequently and Jeep needs to step up and do something before someone is badly hurt or even killed. I have the 180 amp alternator and who knows at this point if it took out the motor module or if the TIPM is faulty. JEEP/CHRYSLER....me and my attorney will be in touch if this is beyond the alternator!!!

Grand Cherokee Limited 5.7L Hemi

  • Automatic transmission
  • 92,000 miles

On 3 separate occasions in 2015 (June, Sept and Oct) the jeep just shut off while I was turning. This always happened first thing in the morning, but not during the first turn of the morning. Usually it happened 5-10 minutes into my trip. Twice it happened while I was turning right, once while I was turning left on the highway. The car just shuts off, and the wheel locks, leaving you stalled in the middle of an intersection with no warning. No engine lights, no codes, - nothing. Quickly put car into park, and it turns right back on. Rest of the day it works fine. The stalling happens randomly and with no common factors, except in morning.

Took it to dealership in October 2015. They were not able to replicate this. They did research into it, and said there were no recalls that would affect this. TIPM was recalled/replaced. Battery was slightly below normal. Told me the steering was electric, and connected to battery. If it pulled too much power, it could shut off the vehicle. Had a new battery installed, and it seemed to solve the problem.

It is now September 2016. Jeep stalled while turning right on Friday Sept 2, 2016. Didn't drive it much foe a few days. Engine stalled again Tuesday morning while turning left across traffic. dealership has vehicle again, and cannot replicate the engine shutting off, with no codes. I call edge Jeep, and they hadn't heard of this issue. My case number with Chrysler is 30062693.

Any help or suggestions?

Grand Cherokee Limited 5.7L

  • Automatic transmission
  • 70,000 miles

Engine Stalls on Right Turn - Exiting Highway. Three times stalls exiting the same highway same location. November - 2015, December - 2015, March 17th 2016. January - stalls slowing down at a traffic light. The bad thing - you lose a little control of vehicle and anything can happen.

I had the Jeep in for the recalls in January. Fuel relay was replaced, sunroof module was attended to, booster brakes were attended to. I was told what was done will fix the stalling problem. until yesterday March 17th when I stalled again at the same exit.

I need some answers for me and other people safety.

I just learned of this site but wanted to address our issues with our 2012 Jeep Grand Cherokee.

What a major cluster &^%&.

Since we have owned the vehicle the car has “Stopped Working” while in motion 6 times, twice almost killing me. I was driving down the turnpike (60+) and the car DIED! It happens randomly. They have changed the TIPM, Fuel Sensor and battery …. Still happening. You can’t put it in park while going 60MPH, you have no power steering so you have to count on your strength to glide into the emergency lane and stop the car. Then turn it off and hope that it turns back on.

This last incident happened Sept 14th, our dealer’s response was to tow it in, we did. They have had the car now for 10 days and they do not have a clue what the issue is. I am told they have to “recreate” the issue because there is no “CODE”, good luck…. We have asked for the FLA tech support person to come to Miami from West Palm to help the dealer troubleshoot.... but you need approval from Chrysler who said they need to recreate the issue. Its a major hamster wheel that we are on and its outrageous that no one knows what is the issue.

I have opened a case with Chrysler and our case manager is clueless and claims they have no other car out there with this issue. Well that doesn’t seem to be true based on this site.

What needs to happen, someone get KILLED and then file a lawsuit like what recently happened with GM?

Grand Cherokee 5.7L

  • Automatic transmission
  • 60,000 miles

My 2012 Jeep Grand Cherokee in July of 2014, apx 60,000 miles, engine started to shut off while the vehicle is in drive and driving. Typically this would happen while braking or making left hand turns. The only way I knew that the engine was off is that the brakes do not work. Nor does the emergency brake or power steering. There are no warning lights. The radio and light remain on even with this engine failure.

After the vehicle comes to a complete stop, you can place in park to restart. At first I thought maybe the key fab was getting hit and shutting off. Upon contacting the dealer they told me to bring it in. At this point I was scared to drive and the dealer would not tow it in. I called the extended warranty company who said they cannot say if the tow will be covered until they know what is wrong with it from the dealer to see if it is a covered item. So I drove it I. South Oak Jeep could not figure out the issue but said they cleaned the throttle blade and reset electric throttle and adaptive memory, road tested for 5 miles and verified okay now. This cost me $125.00. They said it was not covered under the warranty. (Turns out they never called the extended warranty to even see).

Which now brings me to April 8,2015. On a busy road that is 55 miles I am coming up to a 4 way stop and my vehicle will not stop. Same issue again. This time I barely avoided a major collision. Called dealer, they can get me in the next day at 10:00 am. So the day I bring in the vehicle they call at 3:30 to say they are unable to duplicate the problem. There are no codes. They do see a tech case with regards to this issue with possible fixes. So now they suggested I pay $237.50 for a new fuel pump circuit which may or may not fix the issue. Hmm... The extended warranty will not cover this due to the fact that the dealer is guessing physical evidence. They cannot say this will fix this issue. No kidding, my thought exactly.

Warranty company said the dealer told them it was a tipping power module junction box in the engine bay that needed to be replaced. I opened up a case with Chrysler Jeep. Case #26779075. So this time I have to comply and fix/replace parts that may or may not be broken. Charging me for part changing until we can find out which of many it could be. Chrysler Jeep, South Oak Jeep do not seem too concern that there vehicles just shut off while driving. So I am now putting this out there so when I crash into you the next time it dies we all know who to go after. I am clearly not the only one with this life threatening issue.
