I was driving my jeep from a stop sign and it all of a sudden slowed down and would not accelerate. The engine light comes on and forces me to pull over, restart it and it runs fine after that. Well, it's happened 3 times after this and I have arranged a 7am service for it on monday. The book says check the gas cap or it may be bad gas, but I burned the gas down to 15 miles left and filled it with super unleaded. No matter what I do, like shift into n, rev the engine, nothing works until I pull over and restart it.

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 after 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 cylinder heads and want both heads replaced.
Engine light came on 3 months ago, took to dealer said it was nothing. I asked why did it come on they said it's just computers some times they have to be reset. Engine felt like it was going to die. Engine light came on monday took to same dealer. They said I had cylinder misfire in the 6th cylinder and had to replace it. After searching on the internet I see this is a problem with jeep cherokee 2012. Why is this not on a recall?
The contact owns a 2012 jeep grand cherokee. On 5/8/2012 the contact pushed the start button on the vehicle, the lights on the vehicle flashed once, and immediately the vehicle turned off completely. Contact pushed the start button again, the lights in the vehicle remained off, and the engine did not start. The vehicle battery was completely dead. Contact attempted to jump start the vehicle in order to drive it to the dealer but vehicle still would not start. Subsequently the vehicle was towed to an authorized dealer for repair. Dealer determined vehicle had a bad battery. Per the invoice received from the dealer "body ground at battery was not secure" and after installing new battery mechanic noticed "sparking at lower negative cable on body" and that he "found nut for stud laying in the bottom of the battery tray". Mechanic then noted he fixed the above problems and re-installed the new battery. Dealer then returned the vehicle to the contact. The manufacturer was notified of the issue and a case was assigned.
The contact owns a 2012 jeep grand cherokee. The contact stated that on 6/24/2013 the malfunction indicator light (mil) illuminated driving approximately 35 MPH. The contact called the authorized dealer and notified them of the issue. The dealer stated the light was most likely caused by a loose gas cap. The dealer instructed the contact to give it a couple days and it would most likely turn off. The light turned off after 2 days. Subsequently on 7/10/2013 the malfunction indicator light illuminated again while traveling at 50 MPH and the vehicle stalled. The contact restarted the vehicle. The vehicle was taken to the dealer the next morning. The dealer ran a diagnostic test and informed the contact that the failure was caused by cylinder number 2 misfiring in the head of the engine. The dealer replaced the head, valve, and cylinder number 2 on 7/13/2013. Vehicle was picked up on 7/15/2013 and the next day the malfunction indicator light illuminated again. Contact notified the dealer of issue and will be taking the vehicle back.
This jeep was replaced because the prior jeep was lemon law. The engine light appeared after about 3 weeks of purchase, the car was brand new. Like the last jeep, it would stall causing loss of power brakes and power steering. The electrical system would also freeze (navigation and radio) constantly and would not fix itself unless the battery was unplugged. Shave jeep in thousand oaks, ca upgraded the engine and navigation software, but problems resumed short after. Shaver jeep then informed me that they would only look at the vehicle if the engine light was on. The engine light would go on and off so it was hard to time it right to bring it into the shop. Because of this "rule," shaver jeep will not acknowledge that the car has been brought in for repair 7 times. As of today, the car stalled on a busy freeway and put the passengers in danger. Constant engine code: crankshaft position sensor.
I was driving home for lunch and smelled a very sharp scent that burned my throat and eyes. I rolled down the windows thinking it was the car in front of mine. I saw white smoke on the right side of my vehicle and than the passenger visor melted off the ceiling and followed it was a fire at the sight of the visor hole. The fire dripped down onto the passenger seat and I called 911 and pulled over. I ran inside and 2 gentleman came out with a fire extinguisher and put the fire out right as the fire department arrived. *tr.. Updated 08-20-14 *bf updated 08/25/2014
My issue with the jeep is that I believe it has an design and engineering flaw. This vehicle has an automatic transmission. When the shift lever is in drive the lever if bumped accidentally to the left it will down shift. This has happened to me on several occasions. I was traveling in excess of 65 MPH's the first time it happened and didn't realize what had caused the downshift. This is very hard on the transmission and engine not to say a major safety issue. I'm left handed and drive such, many times I have caught the right sleeve of my shirt on the shift lever and have caused the transmission to downshift . I believe there should be a lever or button that should be depressed to allow the downshift to occur. Please address this issue. Thank you!
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. Http://www.autoweek.com/article/20120813/carnews/120819959.
Tl* the contact owns a 2012 jeep grand cherokee. The contact stated that the engine warning lamp illuminated. The vehicle was taken to the dealer. The technician stated that the cylinder head was corroded and needed to be replaced. The manufacturer was not made aware of the failure. The vehicle was not repaired. The failure and current mileage was 47,000.
The incident occurred during acceleration up an entrance ramp incline from 30 MPH to 50 MPH entering the highway. When entering the highway a vehicle moved into my path at which time, I quickly moved my foot from the accelerator pedal to the brake pedal to find the brake pedal was hard to press and my car did not respond to any brake pedal input, at that moment. I had to swerve to avoid contact with the other vehicle. A very short time later, the brakes appeared to function normally again. I was able to recreate this condition multiple times and brought my vehicle in for service. They were unable to recreate the condition initially. I rode with the technician and walked him through the steps to recreate my experience. He confirmed the condition existed. The dealership has replaced a brake booster vacuum hose and can still create the condition in my vehicle "a brake pedal that is hard to depress and does not slow/stop the vehicle immediately." chrysler has stated it is aware of this condition in it's pentastar 6 cylinder due to low vacuum brake boost under certain conditions and describes the condition as a "characteristic" of the engine, further explaining the "vehicle is working as intended." while every one at the dealership and chrysler was nice this is a safety concern that needs to be remedied immediately. Not having responsive brakes under all conditions is not acceptable, this is not a "characteristic" but a design flaw that someone needs to address before too many units are on the roads and experience the wrong conditions at the wrong time and someone is not able to swerve or stop in time. I can't imagine this has not occurred already. There is a "chrysler start case" with this information in it.

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.

I bought my band new 2012 jeep grand cherokee overland 7 months ago - brand new from the chrysler jeep dealership and about a month after I bought it I started to notice the acceleration is not 100%, the windows stop rolling up or down for hours at a time at random time, the brakes sometimes don't work all the way, the engine jumps when switching gears and most recently my check engine light came on, the car would not accelerate and the rpms would not go past 1.5 even when flooring it & there were loud clicking noises with a loud fan. This time I was not able to drive to the dealership - I had to tow it in because it was not drivable. I have taken it to the dealer ship 3 times for them to check on these things & everytime I take it in they tell me they are "unable to recreate the problems" & cannot help me. I have called numerous times to complain & report issues and they either tell me they cannot help me, they put me on hold for an infinite amount of time, I go to voicemail, or no one is available. They called me today, after having it for 4 days, and told me the check engine light was for a "evap perg system" so they replaced a hose & updated my power control module as a precaution. When I asked them how this had anything to do with my engine problems he could not explain it. When I asked him why my engine has problems he could not explain it. No one there wants to help me - what I feel like they are doing is giving me excuse after excuse in the book, stalling me for as long as they can until my warranty runs out. I have dealt with 4 managers there - the 1st one stopped returning my phone calls, the 2nd one told me I am imagining things and I should stop complaining and be thankful that I have a new car, the 3rd one pond me off onto a 4th one & the 4th one told me to my face that I am a liar and I am making up stories so the situation looks worse then it actually is.
I started the engine of my 2012 jeep and as soon I began traveling with the jeep fluids poured from the middle of the engine. I did not notice this until I stopped the vehicle after driving 10 minutes. The computer did not show any signs of an error or engine trouble. When I stopped the vehicle and looked under the front of the car I saw a steady stream of orange liquid pouring from the middle of the engine. This fluid was engine coolant. I immediately had the vehicle towed to a local chrysler service station. My jeep has been with the service department for over two weeks now. The jeep cannot be fixed due the fact that chrysler has no spare parts.

Turned onto state highway when engine began to make seizure noise and temperature moved toward h with shaking and lost power from engine. I put on emergency blinkers, removed foot from accelerator, tapped brakes, with noise continuing, while attempting to accelerate again with no power occurring. I drifted slowing down the highway a few hundred feet, turned onto a side road, with violent engine seizure noise continuing and turned off vehicle. Vehicle restarted without a problem. I got vehicle towed to dealer to be checked since I purchased the vehicle only two weeks prior. I highly suspect engine debris caused this very dangerous incident. I thought an explosion of the vehicle would occur and a crash from approaching vehicles. I will not take delivery of the vehicle in incident and requested out of contract.
We purchased a new jeep grand cherokee with 5 miles on it. Upon leaving the dealership the engine began making a strange noise. We brought the car back to the dealer and the mechanic told us to leave the car. It's 5 days later and all we know so far is that they have removed the front end of the transmission and they are still working on it. We don't have the car. Additionally, the front driver's side door was not flush with the body of the car. We asked them to look at the door to see if it was not installed properly. They offered to have the body shop bend the door.
I was going approximately 20-25 approaching a signal light. I let off the gas and applied the brake as the light was red. As I let off the gas, the engine began to rev higher and as I applied the brake I had to apply it harder and harder as the engine continued to rev even higher. I began to smell the brakes burning as they tried to hold the car back. Fortunately I had the foresight to put the car in neutral. It continued to rev for about 5 seconds and then went down to normal. It has happened once. No warning lights went on. The dealer said that they contacted the detroit technical bureau and they suggested that maybe it was the floor mat, or my foot, etc, etc but claimed they had no other reports of this occurring. I don't have carpets as I opted for the rubber mats and they sit tight to the floor. And my foot was not stuck on the gas. I was conscious of the fact that my foot was on the brake and not the gas as I was trying to figure out what the heck was going on. They said they drove it and did computer checks and had no explanation. The service rep said the response from the technical bureau would be "insulting to me". The dealer was bradshaw jeep in watertown, ct and the service rep was victor. I wrote this out on the service order and kept a copy.
