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.

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.

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.

Failure Date: 06/09/2012

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.

1. My 2007 Jeep Grand Cherokee (5. 7 hemi; 64k miles) was due for a tune up. I purchased replacement spark plugs that were recommended from a local auto parts retailer and changed them. 2. Subsequently the vehicle began to stall frequently while driving (approx 5 times in 25 miles traveled). This happened while driving at highway speeds, at stoplights and when making left hand turns. 3. Vehicle was taken to dealer for service as engine light had also been on during entire time. Dealer worked on trying to find problem for 3 weeks. After consulting a Chrysler engineer they finally discovered that the aftermarket platinum tip spark plugs were causing interference with the vehicle powertrain control module and causing the engine to stall. Dealer replaced the spark plugs and the problem was corrected. I went back to my parts supplier and they had never heard of this problem before. I also notified Chrysler of my complaint that consumers and parts supply retailers should be made aware of this parts incompatibility issue that they are obviously aware of because it is a potentially serious safety hazard. They have not responded to me.

Sometimes when I drive the engine feels like it stalls out and my rpm's don't move, all the boxes around prnd light up and the check engine light comes on. I have to pull over and put the car in park or sometimes I have to turn it off. Once this is done the car continues to drive like nothing happened but the check engine light will stay on for a day. Sometimes it happens on the highway which is very scary to just drop speed down to 40. I have read many blogs about this issue. It happens at random times.

Vehicle loses power at interstate speed. Incidents: 5-30-2007. Wife was driving vehicle on interstate. Vehicle just turned off after loosing power. Wife pulled to shoulder of road and put into park. Restarted engine. No 'check engine light". Took vehicle to dealership for system scan. Sonya rechtorovic at landmark Dodge (770-968-4900)checked vehicle into repair. Received paperwork which says "customer states while driving on interstate, vehicle shuts off. No codes in system. All systems operating as designed.

"joe brooks" at douglas county Dodge at 770-942-1102 and vic daniel at landmark Dodge at 770-968-4900 or 678-251-2327.

Received error code "u0404 code- invalid data received from gear shift control module". Seen recall d46 for 2005 Jeep Grand Cherokee to reprogram pcm. I believe my 2007 Jeep Grand Cherokee laredo has this issue. Called Chrysler at 1-800-853-1403 at 1045 am on 7-6-2009 and spoke with "dan thomas". Dan looked up my VIN number and stated that "no recalls are for this vehicle and if a recall does come out, then a letter will be mailed to you".

I was driving my '08 Jeep Grand Cherokee laredo and driving on an on-ramp today to get on the freeway going about 35mph, when all of the sudden I lost all of the electric in my Jeep. The radio went out, the odometer and temp/compass went blank, and I lost the power steering. Luckily I was able to steer it over to the side. I then turned it off and back on and there didn't seem to be any problems. I drove it another hour and half home and didn't have any other issues. No check engine light or warning lights came on at any time I took it to the Jeep dealer, however they claimed they could not find any issues.
