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.

Car's tipm has been messing up. They say there hasn't been a recall on my model for that and another says it has been fixed. My car won't start at times, my horn honks at random times and just today my car stalled while on the interstate. I know the tipm had been a problem with these vehicles but I cant get any help with mine without paying out of pocket. I've about had it with my Jeep.

While driving locally on a city street, heard a low whining sound, followed by the dashboard battery warning light being illuminated. Sound increased and decreased with vehicle speed. Drove immediately home, less than a mile, parked the vehicle, opened the hood and isolated the location of the whining sound to the alternator area. At this time I could also smell a burning odor (being an electrician).I put a meter to the battery terminals and recorded a voltage of 11.5, indicating that the alternator had failed. There were no visible signs of smoke that I could see as the time was about 9pm. But the smell of an electrical issue was clearly present.

I've noticed lately that while making turns in my overland summit with a 5.7L hemi, that the Jeep will stall out and die in the middle of the maneuver. This only happens when making turns. I have to shift into neutral and apply the brakes and press the push start to turn the engine back over. It always starts back up but this is starting to become a real concern. I asked 2 different Dodge Chrysler Jeep supervisors about this and they claim to have never heard of anything like this, even though there is an active recall for this very thing. They now say my vehicle wasn't affected even though the symptoms are the exact same thing.

The fuel pump was replaced per recall and now the new external fuel pump is completely failed and my Jeep won't start at all. Sometimes it will start and other times I will be driving down the road or highway and the vehicle will just stall and turn off on me. Someone has to do something about this.

This Jeep had the fuel pump recall done on it which was for the tipm relay built in fails causing these Jeep and durangos to stall out. Well now the whole module is bad per the dealer. This failure is worst than the relay failure. The Jeep stalled out while being parked and would not start again also while not working sitting in my garage the Jeep tried to start on its own and lights and horn going off. Jeep was already sued over this and I have been reading forms with many other customers still having this issue and these modules should have been replaced not placing a bandaid on the relay while the whole module is garbage which is now costing me 1600 and we haven't been able to drive it for a month since she was scared to be left stranded or having the car stall while driving. Please bring this up with them I already emailed asking for help on this problem since they never addressed it the first time it was brought up.

While driving vehicle, noticed a smoke smell of something burning. Couldn't put a finger on it until later while driving the car filled with smoke coming from the passenger side headliner and burn hole in liner. Pulled over and pulled headliner down and saw flames and smoke. Put fire out. Called dealership and there was a recall that had been done by them on our vehicle for the vanity mirror electrical problem previous to this incident. They took our vehicle and gave us a rental at their expense until further investigation of this incident..

Fuel pump, recall done but not effective. Almost three times a week, the Jeep Grand Cherokee does not start or stalls right after starting. This is when I am parked and will just keep cranking and not start. The dealer wants to charge me to replace the fuel pump and does not acknowledge the recall is faulty. Driving on the highway, the car stalled on me for no reason and then took 5 minutes of cranking to finally start again. Luckily I was not in the middle lane on I95. At first it happened once or twice a week, now it is almost everyday.

Fuel pump relay failed after being replaced by recall. Occasionally the car would not start. Most recently the car stalled on me while in traffic. The first time I was able to coast to the shoulder and restart the car. The second, and last time it stalled, I was turning off a residential side street onto a major 4 lane road during rush hour. It stalled in the intersection. I could not restart it. I was told by my auto shop that the part has not been improved, only replaced. That is not a fix!

The automatic charging system light came on 2 hours into driving North on the highway to Wisconsin from Chicago. There was no human action that correlated with the light coming on. It simply came on when going consistent speed on the highway in no traffic. I learned from the driver's manual that this most likely meant that the alternator had failed and I needed to get assistance immediately. I took the car into a repair shop on a Thursday where it would remain for 10 days as things began to unfold. The employees of the repair shop could identify no fault in the alternator after thorough inspection and driving tests. The warning light had turned off. However, after it had been cleared of all inspection and turned on, there was an enormous failure in the car causing it to smoke. Without warning, the alternator caused such a massive short that it not only failed itself, but also broke the car's engine computer. I come to find out that there was a recall by Chrysler (T36) for this specific issue and included 2012 Jeep Grand Cherokee's. I was never made aware of this recall but there is no question that this failure is specific to the manufacturing errors by Chrysler Jeep. There have been a total of 10 recalls on the 2012 Jeep Grand Cherokee, 3 of which have been specific to this vehicle, and clearly, now a 4th. This could have been a been an incredibly dangerous situation and the failure by Chrysler to notify me or include my vehicle in their recall is preposterous. I have documentation regarding repair and claims attached. More info and claim documents available upon request.

The 2012 Jeep Grand Cherokee will crank with no start. The Jeep refuses to fire up, it will crank for long periods of time but will absolutely not start up. Could be an electrical issue or fuel pump relay or engine. Seems a lot of friends of mine are having the same issue with this very same model. Please help me with the defective car.
