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.

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.

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.

I had a recall on alternator which I had recall on and didn't received a letter in the mail. So one day I was driving with my family and I smell smoke coming my hood which I thought my car was on fire so I pull over and got out the car and call road side service to tow my car to championship of Decatur. They fix the recall on the alternator and didn't replace my battery which was low. They charge my battery and everything was fine so I pick my car up and when down the street for 4 miles and my car cut off again so I had to get to auto zone to get a battery. I have a new battery and alternator and my Jeep is still no powering on. I do not feel safe driving my vehicle anymore I have a 1 year daughter and another baby due any day now. So how can we resole this issue its not safe having a electrical system problem.

2012 jgc,54K miles. I appear better off than some, as my Jeep's only real issue, at the moment, is that it cranks but wont start. Disconnecting the battery and leaving it for an hour will re boot the tipm and car will start. Dealership singularly unhelpful, and Chrysler customer service declined to help. I can see why.

With only 50,800 miles check engine light produced several codes. I took this vehicle to 3 different places for a diagnostic test. They said it was power steering / A/C coolant leaking. With the 2nd diagnoses they found a leak with the auxiliary cooler (transmission fluid). So I had a complete transmission flush work done, but it's still leaking..

Engine randomly stalls for no reason while in motion, leaving the car coasting with no power brakes or power steering. Once the car is brought to a stop, it will start back up and continue driving as if nothing was wrong. Internet searches reveal that it is a common problem afflicting these models with no clear solution.

Purchased used 2012 Grand Cherokee overland w/94637 miles on January 27 2018. On January 31 at 8:50am after driving two miles I came to a stop at a stop light and while waiting for light change the engine died. No warning lights - the only indication was RPM dropped to zero. Put vehicle into park and restarted without a problem. Continued driving for the remainder of 32 mile trip. Again on February 2 2018 the same thing occurred while my wife was driving. She came to a full stop and while waiting for signal light to change the vehicle engine quit with no warning lights. On both occasions this was the first trip of the day in the early morning ambient temperature of 55 degrees on dry pavement on city streets. Both times the vehicle was restarted without a prolem and the trip continued without interruption. Vehicle is scheduled at folsom lake Jeep dealer for investigation.
