I have 4 recurring problems with my Jeep. First, the driver's heated seats periodically will not work. Second, upon starting my car, it will just stall or shut down. This happens 2 to 3 times a week. Third, the check engine light continuously comes on and off (and when I get it checked, I am told something about the thermostat, but have had no problems with it overheating). Finally, the cruise control on/off button will not work sometimes. I have to physically hit the steering wheel for it to work. I have read about tons of recalls for my year Jeep, but my VIN number is not included. I am starting to think it should be.

The 2012 Jeep Grand Cherokee check engine light was on and stalled then pulled over to side of street then restarted engine. Took to Dodge dealership -had major engine failure no-to low compression on lft cylinder head. Is the fuel tank on this vehicle defective will it leak and explode/catch fire if rear ended? this vehicle was owned by dealership with open/active recall safety defects. Should I be concerned with driving this vehicle. Dealership did not disclose this when they sold the vehicle. How is this legal and allowed to get away with this dangerous vehicle. I don't want to put my family in it. Maybe the dealership owner will put his family in it since he's selling defective cars. I just get another safety recall notice. This vehicle is an accident/fatality waiting to happen. The manufacturer/dealership should refund the purchase price or be criminally charged. I paid thousands of $'s, this vehicle is a total loss who going to buy it.

Bought Jeep new on 12/2012. Check engine light came on last week, took it to auto parts store to have it hooked up to computer and it read cylinder 4 misfiring. Called Jeep dealer and brought it in for service, they called and said it was the cylinder head and will replace. This makes me very concerned to see so many others having similar problems. Wasn't even given a loaner car while repair was done because I didn't have the extended warranty. I only have 15,000 miles on car, shouldn't need extended warranty!! maybe Jeep is trying to tell us something.
I brought my cherokee into dealer where I purchased it for a check engine light. The Jeep was looked at and the lead mechanic proceeded to tell me it would need a cylinder head. I bought this Jeep on 11/7/11 and couldn't believe what I was hearing. After reading many forums and Chrysler's comments; which they don't take full responsibility for this critical issue by putting some fault on the customer. Brand new vehicle which I paid a good amount for and after 20,000 you have to rip my truck apart and now I hope for the best. I feel this is just a band aide to cover the major problem with this 3. 6-l engine. To me now it's as if I bought it used. If I try to trade the Jeep in I'm sure it has depreciated and the same if I was to sell to a private owner. I truly feel I was taken advantage of by Chrysler and to pay that amount for a vehicle which clearly has mechanical problems, well to me, that is just not acceptable. I know fires under the hood are being investigated, I am very concerned on this issue as well. I think my cherokee should be warranted for the life of the cherokee by Chrysler due to the mechanical problem returning after another 20,000 or 25,000 miles. Thank you for your time.
Check engine light went on and service dept for my dealership said it was the cylinder head. Still waiting for part to be delivered. This is a known problem for Chrysler since 2012. In 2012, I had to have the intermediate steering shaft replaced. Jeep was purchased new in 2/2012.
I bought the vehicle from a dealer with 14,500 miles on it. Still under the 3 year, 36000 mile warranty. Started the engine only to have the check engine light illuminate. Drove byautozone and red the code, p0304, misfire on cylinder 4. Brought the vehicle to the dealer where purchased and he sent it to the Jeep dealer for service. I was given a loner car from the dealer I purchased it from. I received the vehicle back on wed. July 31st from my purchasing dealer and was told the computer was flashed and re-programmed. Thursday morning, the day aftr the repair the check engine light illuminated again. Called the dealer I purchased the vehicle from and will be dropping off Friday morning. I know of the inherent issues with the 3. 6 l pentstar engine cyllinder heads and want both heads replaced.
Check engine light (cel) is on with p0300 and p0302 codes, exhaust escaping #2 piston head- causing rough idling, cel flashes, and several stalls while in motion. Found out this is "common" on pentastar engines, and parts are not readily available from Chrysler to make repairs, and dealers let people drive the car instead of providing alternative transportation. They should have to repair and replace these heads that have now been redesigned in more current builds. Letting people drive cars that can stall in motion is dangerous. Not having parts readily available when they are having 300 to 400 of these failures a week is ridiculous. The attached link shows that Chrysler had this part shortage since last summer, and is not meeting the demand for replacements even now. . Read more...

A check engine light came on whilst stopped at a red light. We took it to autozone and they plugged into it and they displayed a misfire on 2. This is the 2nd time it happened. The first time Chrysler changed the head. Now its in the shop for the same issue. I am waiting for the dealer to get back with me on what Chrysler is going to do.
The contact owns 2012 Jeep Grand Cherokee. The contact stated that the check engine warning light was illuminated. The vehicle was taken to the dealer who ran a diagnostic test and advised the contact that the head cylinder gasket malfunctioned. The vehicle was repaired. The manufacturer was notified of the issue. The failure mileage was 13,150.
Engine started running roughly and attempted to stall in traffic. Check engine light came on. I went to Jeep dealer in gulf shores alabama and was told that the left cylinder head was defective. I was also advised that it was a manufacturing defect that could result in catastrophic engine failure. It is a well known defect in the 2012 cherokees with the 3. 6 pentastar engine. If this vehicle had stalled while on an interstate ramp, or a valve in the defective head dropped down into the cylinder, an accident could result. Jeep has full knowledge of this defect but has not issued a recall. This could be as serious as the gm ignition switch issue.
