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.

Vehicle stalled without warning. No power whatsoever. Illuminated battery light came on. Noticed a burning odor coming from vehicle. Checked engine bay and noticed heavy smoke coming from alternator for a good 10 minutes. Vehicle would not take a jump nor could I put into gear. Battery is completely dead. PCM also seems to be fried. Will have to be towed to Dealership. Called Jeep costumer care and referenced the t36 recall but my vin does not fall under it even though vehicle fits EXACT description of recall. Also noticed that many others are have same problem with Jeep and them not expanding the recall to their vin. How terrible!! This could have easily been a fatal situation. Jeep needs to take some responsibility and action!

Since owning this vehicle (2013), it periodically stalls while driving. There is no warning and most times I am on a highway or getting off an exit. When this happens, I have no power steering ability. I have been lucky so far and I have not caused a serious accident when these episodes have occurred. My wife refused to ride or to drive the Jeep because of this problem. I see online that other Jeep owners have experienced the same problem. I have taken it to a Jeep dealer for service since 2013 and they are never able to diagnose the root cause of this problem. This problem seems to be happening more often - I fear for my life and those around me due to this sporadic problem. Please hold Jeep responsible for getting to the root of this issue with these vehicles.

I was driving home from work and entering a highway merging into traffic at about 50mph, all was operating normally the Jeep was accelerating and I was turning the steering wheel to merge into the traffic. Suddenly without warning there was a noise from under the hood that can best be described as a "pop" which was followed by a burning smell and power loss. I managed to coast out of traffic and onto the shoulder of a 12 lane highway and called my roadside assistance who when they arrived immediately said it was the alternator without even lifting the hood. The incident occurred without warning on a major highway with busy traffic which could have easily resulted in an accident for myself and others. The Jeep was taken to the dealer who diagnosed an alternator diode failure, which also damaged the battery I had recently replaced. i authorized the repair which was accomplished without any issues, I have attached the paid invoice for this repair which totaled $874.06 +/-.

In the span of about 2 years, I have had the fuel pump TPIM safety recall performed about 3 times. I-??ve had a new fuel pump, battery, new alternator, power board installed, all out of pocket and my 2012 Jeep Grand Cherokee Hemi continues to randomly stall. The dealer always says there are no codes and basically cannot do anything for me at this point. Do I have to wait until I am in a serious accident before Chrysler does anything? Go on any jeep forum and I know I am not the only person experiencing this issue. This is a safety issue that needs to be corrected before someone is seriously injured or killed.

There is an open recall for the fuel pump relay on my Jeep Grand Cherokee, [XXX]. I've called every dealership within 50 miles of where I live and all of them tell me that Chrysler has only allowed them to order parts for 1 vehicle a week and they all over 100+ vehicles backlogged, meaning if circumstances don't change it will be 2 years plus before my vehicle is repaired. Now I'm going to have to pay for temporary repair out of pocket as my vehicle is already intermittently failing to start due to the relay failing. This is ridiculous and Jeep needs to get their act together before someone gets killed when this relay dies at the worst possible time.
