Misfire or rough idle by model year
What owners say
The left bank intake camshaft and roller rockers have failed. It has cause the check engine light to come on and go off reading a misfire in cylinder 2. After costly repairs to coil packs and plugs, Chrysler is now going to replace with a cost of $1,900.00. This is the same issue in the 2013 Jeep that Chrysler extended the warranty on and won’t do it now on this year model.
The right cylinder head is misfiring and needs repair. the federal safety agency previously investigated complaints on the left cylinder head. MOPAR issued a warranty bulletin (D-14-12) on June 10, 2014 for 2011 - 2013 model vehicles for left cylinder head extended warranty coverage period of 10 years/150K miles. Upon my further investigation, the cylinder heads misfiring is a known issue on model years beyond 2013, yet Mopar has not issued an extended warranty bulletin. The cost to repair it is thousands of dollars. My model year 2014 was manufactured in 2013. If this is not repaired, it will do permanent damage to the catalytic converter, and beyond. The dealer inspected the vehicle and confirmed malfunction. No prior warnings given prior to cylinder head misfire, when it happened the Check Engine Light came on.
Cylinder head misfire #2 and service four wheel drive light. I had taken it in to our local mechanic he said the head needs to be replaced there is a current recall and extended warranty out now with the same problems but our jeep is not on the VIN list (pentastar tic) is what our mechanic called it.
I bought this jeep in 2018 with low miles 40,000 now in 2021 has 68,000. I have been driving the car only to go work and working from home I wasn't driving that much. Suddenly while driving I noticed a light on and it was on and off, and oil smell. I took it for the diagnostic and the code misfire detected in cylinder number 3., p0303 ,which is a problem with the engine. The price is 4000 to fix the problem because is a misfire in one of the cylinders of the engine. The car is not working properly because it has a oil smell and some issues when I am driving such as shaking and also a weird sound . This is the only car that I have right now and I am scare to drive it because I don't think it is safe to drive it with oil smell, it might caught on fire or something . The starter is not working and when driving is unstable. I just drive locally I don't know how this car is giving me an engine problem with that low mileage. It is not possible that a car parked and using not often could have an engine problem. I bought this car thinking to keep it for a long time since I always take a good care of my cars. I need an explanation from jeep regarding this problem. I am not going to spend over $4000 in a car with less than 100,000 miles and with a problem that was not done by me. I need to resolve this since it might be a safety risk if I continue driving this car with some type of engine/ oil smell. When I parked the car a strong burned oil smell comes out and goes inside the car.
When car is in motion, car runs rough, hesitates, sometimes brakes are slow to react. When stationary circuits short for remote start, outlets and operating back lift. P0013 code is on this vehicle. This vehicle is demonstrating the same functions as those other jeep vehicles that were recalled.
3.6 l left side, cylinder number two misfire bad valve guides & valve seat. Confirmed
P0032 code came up went for check engine light. Went to get it looked at. Tech then told me that it was a miss drill of the heads causing the misfire to happen. The tech then also stated it was a known mopar issue in jeep grand cherokee line.
The engine started misfiring. Code reader said #6 cylinder. Plug, coil, and injector didn't fix it. Dealership diagnoses left cylinder head bad. Cylinder 6 losing 65% compression. At 75k miles I was 2 weeks from out of warranty. Dealer said it is a known problem but they wait until they go bad to change them. I expect this cost customers a lot of money for a big expensive known problem that they won't take responsibility for.
Constantly will make a squeeling sound every morning on start up. Lasts over a minute - not even on cold days! Have had it looked at - state can't duplicate the oeuvre (of course because it's always the first start up! Rough idle every 2-3 minutes, transmission shifts hard out of first gear. Pour fuel economy as well. Maintenance has been done. Just bought the car - several issues
Constant cylinder 6 misfire. All 6 spark plugs have been replaced. Coil and fuel injector replaced. Still showing cylinder 6 misfire. Seen cylinder head being replaced on years 2011-2013 but not for a 2014. This should be covered. When the check engine light came on, it had seizure like convulsions when coming to a stop and while in idle until spark plugs were replaced. Still running rough, very shaking like it is going to stall out.
On 9/24/2016 I was driving in florida going on vacation and the motor (pentastar v-6) started misfiring. Took it to a jeep dealership in fort walton, fl and was told that it need a tune up. Was charged $308.67 for the tune up. Drove the vehicle about 10 miles and the misfiring started again. Took it back to the dealership and was told it needed a new head. They replaced the head and we took the vehicle and started back to our condo and it started misfiring again. We left the next day and returned to our home in west virginia. Took the vehicle to a dealership here in charleston, wv and they said it was a bad coil. We were again charged and the total was $279.27. It appears to be fixed. I have been researching this problems and appears there are thousands of these motors with that have experienced this problem.
