While driving approximately 40mph my check engine light started dinging and blinking. Within a few seconds of this the engine powered down ( rpm read 0). All the electrical components stayed on (radio, lights, ect) then within 10 seconds the engine started back up. When the vehicle restarted itself the esp showed being disabled and the rpm's where higher than normal. Any acceleration/deceleration the check engine light would ding and blink. This has happened multiple times since it first occured. I have taken it to two mechanics to be serviced. The vehicle displayed random codes at both shops.

While accelerating the vehicle lost power and the prndl lights all illuminated. After a few seconds power resumed. This has happened several times and the check engine light has come on. We have been told its error code u0404 and the electronic shift module needs to be replaced. It appears this is a very common occurrence for this year vehicle. It is a safety concern because if it happened during high traffic times it could certainly cause an accident.

On two occasion my check engine light came on. Both times the thermostat gage kept going up and down. On both occasion I took the vehicle to have it checked. On the second occasion that this happened I was told that a technical service bulletin had been issued for this problem. (pull code #p2181) I was also told that I had to take the vehicle to a dealer to have it taken care of. Since this is a manufacturing issue I felt that it should be taken care at no cost to me but was informed that I would need to in fact pay for this update. (not only do I need to pay but I also have to take time off from work to have this done).

I really need your help. In April of 2014 I bought a brand new Jeep Grand Cherokee summit edition for $60,000. I was thrilled to have finally owned my dream car since 1997! I started having issues with the car in August. . . And when I say issues, I don't mean the radio blitzing out. The car turned off in the middle of a 4 way intersection and wouldn't restart for 3-4 attempts!!!! terrified I took it to the dealership who said it registered some check engine light codes but they couldn't find why it did that. They turned the light off and had me pick the car up. After repeating the same thing, about 8-10 more times the car just shutting off and going back into the shop a second and third time they now said OH we figured out what the problem was and its fixed. I was thrilled for this to be over! a couple weeks later I was driving on the freeway going 65 mph with no cars around me or insight. All of the sudden the car dashboard said brake!!! and the car applied the abs brakes and abruptly slowed the car down to 40 mph!!!! I was so scared at that point, to top it off the car again shut off and the check engine light back on. I took the car to the dealership for the 4th time where they now have put me in a rental for 40 days. This time I was told my car registered 57 codes but they were not able to fix or diagnose the problem. I expressed my concern when I was asked to pick the car up. I don't feel safe in that car and I have lost faith in that vehicle. I asked that they buy the car back since it legally falls under the lemon law and they refused. They left me no choice but to hire a lemon law attorney. I now have lost faith in Jeep/Chrysler for the way they are handling this. They would rather put myself and others in harms way than to do the right thing. Kelly.

1) driving ~ 45 mph. 2) parking/crash detection sensor on the front driver side makes audible noise for 2 seconds, then noise ceases - this parking/crash detection issue was reported to the dealership 3 days prior. 3) all consoles go blank, to include speedometer (which is digital), temperature, navigation, etc. (driver & center consoles) - hands free phone call linked within the vehicle disconnects midway through call at this time as well. 4) engine appears operational, but seems to be in a lower gear and acceleration is problematic, brakes are sluggish. 5) electrical system in the vehicle reboots while driving ~10 seconds later, displaying multiple warning messages (check engine light, low battery voltage, no abs, suspension system, etc. ). 6) pulled the car over at the first safe location ~1/4 mile. 7) vehicle would not go into park, applied emergency brake and turned vehicle off. 8) restarted vehicle, check engine and low battery voltage light remains on, but vehicle appears stable enough to drive ~2 miles home.

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.

Our Jeep Grand Cherokee has been has been having electrical problems. Several different electrical problems occur after which the check engine light will illuminate. Of these electrical problems the dangerous ones include: headlights shutting off, dashboard completely shutting, and vehicle shut off while in motion. We have had the following replace in our vehicle: burnt wires in our engine harness, faulty solenoid, alternator, pcm, and abs module. The issue still occurs. Purchasing the vehicle in Dec we've brought the vehicle back into the dealership for service 3-4 times. While we haven't filed for lemon law yet, Jeep promised us that they would take a look at replacing our vehicle after a number of problem. Their answer to us was to wait to see if the issue occurred again. While we may file for lemon law, we feel that it will be important that we report these issues as they are experienced by other consumers on forums across the internet.

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.

The Jeep will die at any given time, place, temperature. Nothing seems to make a difference. The only thing I can get to make a difference on wether it runs or dies in putting pressure by hand on the number three computer plug. No check engine light, no codes no nothing. Just a faulty computer design thats putting myself and my family in dangerous situations on a regular basis.

Evts inoperative, no blue light. Took to dealership and found wire to evts emergency button severed, possibly shorted. Repaired wires, did not correct condition. Replaced with new evts, condition repaired successfully. At same time also had recall n58 performed, reprogram instrument cluster abs / al. Then at 4040 miles oil change due light came on and had the first oil change done. The check engine light came on a very short time after that and back to the dealership at 4654 miles. Said it was a defective oil pressure sensor, sensor was replaced, cleared codes and found no additional problems. Now at about 12000 miles the oil change due light never came on, but took the car in for an oil change anyway. Now the check engine light along with a low oil pressure light came on, car did not want to shift or speed up, got off the road and had car towed to dealership waiting to be repaired again.

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.

Shortly after starting vehicle and driving at approx 10 mph, check engine light came on. 30 seconds later check engine light started flashing and misfire was felt, car began to shudder. I pulled over, turned off and restarted, again flashing check engine light and shuddering. Vehicle was towed to dealer, who also felt misfire on cold start next am and codes confirmed misfires in multiple cylinders. Dealer inspected engine but found no issues. Next day, car operated normally. Approximately 1-2 weeks later, on starting vehicle entire instrument cluster lit up, with check air bag warning and lights indicated abs failure and ecs off. Car drove, but I subsequently realized speedometer did not work, it was very frightening to drive on highway without knowing my speed. After restarting check engine light remained on, but vehicle functioned normally. Was going to bring back to dealer, but check engine light went off after about 6 drives. These issues are very worrisome and I feel uncomfortable every time I start the ignition.

2014 Jeep Grand Cherokee. Consumer writes in regards to acceleration problems. The consumer immediately noticed upon receipt of the vehicle, that it did not drive smoothly and lacked power during acceleration. However, she felt it was due to lack of familiarity with the vehicle. The performance of the vehicle deteriorated to a point where a problem was evident. Frequently, not all the time, the vehicle was very sluggish to accelerate and occasionally not respond at all for about ten seconds as the rpm's went up. It felt as the though, she was forcing the gas by pressing on the accelerator pedal, but the gas was blocked from flowing, or the vehicle was stuck in a low gear and not up-shifting. Also, the check engine light illuminated, with only 1,231 miles. The consumer had to return to the dealer, several more times, due to the check engine light illuminating.

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.

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...

While driving the Jeep it dies, we could be driving on the highway at 55/60 miles per hour and the Jeep will die, we could be driving locally at 20 miles per hour and the Jeep just dies -- we have contacted Chrysler many times regarding the problem but nothing is done -- they keep asking us to pay for a diagnostic test but nothing shows up -- when the Jeep dies there is no indication that anything is wrong -- no check engine light comes on, just the rpm drops -- we are worried for the safety of our family that while driving on an highway and all of a sudden the Jeep dies that someone hits us from behind and causes a major accident or worse -- we have told Chrysler we would pay for any work that is not covered under the extended warranty as long as they can fix the problem -- after that statement they have not responded to any further correspondence.

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.

While driving for about 30 minutes, the gears changed from drive to the 3rd gear. Transmission reves up and the check engine light comes on. After coming to a stop, and restarting it, it sometimes goes back to drive mode, but reverts back to the third gear, displays "3" and stays there. Took it to a mechanic, could not fix. Dealer claims no recalls for this problem, but online blogs show plenty of people with the same problem. Help.

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.

On the weekend of 6/9/12, my vehicle began giving starting problems and shutting down while driving. The dealerships service department was closed so I had to wait until Monday 6/11/12. I made several attempts on that day to have the vehicle checked out but the service department kept giving me a run around. The vehicle spent the night at the dealership and was checked the following day. I received a call that my vehicle is ready and was informed that a flash was done and a new computer had to be ordered that's why the check engine light is on. Left the dealership and the vehicle shut off once again while driving and when I attempted to restart it was giving the hard start once again. On 6/16/12 the vehicle was fully un-operational and had to be towed to the dealership. It sat there until the part arrived and was installed. On 6/21/12 I picked it up once again it's suppose to be working great because the computer was replaced. Less than an hour later it did not want to start again. I carried it back down on 6/22/12 and on the way there the vehicle shut down. Later that day found out another part had to be ordered. 6/29/12 my vehicle was ready again and said to be working great and it was because the hard start problem was fixed but the shutting down was not fixed because it occurred once again on 7/1/13 and has been happening constantly for over a year.
