I experienced a serious problem with my 2012 jeep sahara. after accelerating and passing another car while driving, i lifted off the accelerator, but my jeep continued to accelerate. i tapped several times on the accelerator, then tapped the brake a couple of times in case the speed control somehow engaged. i then tried to see if i could lift the accelerator from below with my foot, but it wasn't depressed. the jeep was continuing to accelerate and at this point i was going well over 80 mph. finally i was left with no choice but to depress the clutch and take the vehicle out of gear. i quickly shut down the engine as the revs went through the roof. i coasted onto a side road and attempted to restart my jeep, but it wouldn't turn over. i turned the ignition to the off position and removed the key, put the key back in and turned the ignition at which point it turned over and after about 5 or 6 secs it finally restarted and everything seemed normal. i checked around the accelerator and the floor mat was securely in place and there was nothing around the accelerator to cause it to stick. i have never experienced anything like this before in my life and am 110% sure that the problem was not driver error. my feet were completely off any of the peddles while the jeep continued to accelerate and as i had a clear road ahead of me, i very methodically and calmly took the actions i outlined above in the attempt to reduce the engine speed with no affect until i finally had to shut it down. *tr
Chrysler pentastar 3.6l recall needed for major defect that is requiring major engine rework and complete cylinder head replacement around 12k miles. this is going on now and needs public announcement/recall. *tr please google "cylinder 2 misfire pentastar" this is already reported by ~25% of 2012 owners.
Check engine light came on. initial trip to dealer and they decided to just reset the codes. light came back on the next day. return to dealer and they reported a bad cylinder head. told me to keep driving, car now has more engine noise and power lose. (as a side note the dealership has also replaced, about 3 weeks ago, a"bad"pvc valve which resulted in the air filter and housing coated with about a 1/2 inch of engine oil.). have been waiting on parts going on 10 days. not stupid enough to keep driving the vehicle as the dealer suggested. it is irresponsible for dealers to tell clients to keep driving when this vehicle has power issues and appears at risk for stalling. this is an accident waiting to happen. *tr
Vehicle is currently (dec 2012) at dealer having heads/valves replaced (10th day after waiting 10 days for parts), original report 9 nov: idling engine continues to be very rough, much rougher than when reported to dealer on november 9 2012, dealer did pcm reflash/update as stalling maneuver, after which problem worsened and mil came on vehicle is vibrating abnormally when stopped and idling, all passengers feel the car shaking, almost stalls at times idling engine changes speeds and sound intermittently and is running very loud engine always had slight ticking on left side since new but was never loud or rough loss of power felt at acceleration at top of gears (manual) white exhaust emissions after cold start, this never happened before engine light mil is on and off repeatedly - reads p0306 cylinder 6 misfire gas mileage severely affected (approx 25% worse), car now has 18k miles; dealer said it was ok to drive it - however driving it may cause other damage this is 3rd visit to dealer - when problem first reported dealer service dept said i might have put water in the gas. i have had to push the dealer to fix this and the general attitude has been adversarial and not helpful. *tr

The engine has developed a loud ticking noise starting at about 1000 miles. the ticking is louder on the driver's side of the engine and doesn't appear to be normal valvetrain related noise. with reports of bad pentastar v6 heads making it into production jeep wranglers, i've taken the vehicle to two different jeep dealers for analysis. both dealers said that they think the noise is normal, but did admit they could hear the loud ticking. mileage has been dropping and the engine has stalled twice. a software update was performed, but doesn't seem to have affected anything. *tr
I have had at least 100 times where my jeep has stalled and just stopped running. it has happened when i have slowed down, and has stopped in intersections. it has stopped when starting from a stop etc. i have had numerous manual transmission cars and this has never happened. it scares me , and makes me fear for my life. i have changed the way i drive because of it, with the fear of worrying my jeep will just stop running , when i pull out into traffic. i have had the switches in the car not work, and function erratically. lights stay on, when turned off, after turning them off numerous times, they finally go out. i have had my breaks respond oddly, and get weak. i have had the heater not come on, then turn switch again and it works. have had defrost some on when defrost was off. numerous electrical functions, malfunction. i don't bother with jeep, as my mileage is over 36,000- no more warranty, but these things began, about a month or two into jeep ownership. these problems used to be infrequent, but now this power failure happens often. some days it happens 4-5 times. please help me with this matter, i do not want to be injured or killed, due to this problem. i also do not want my family or someone else's hurt ,because of it either. i started doing research about these issues and find i am not the only one, it is common. i also have a whistle in the brake line, vacuum i think??? it causes the breaks to not be strong at times. i have had my brakes completely replaced and this condition persists, it also seems many with my model of jeep experience this as well. all of the hinges on the doors are rusting from the inside out, as well, i see the paint bubbling up . *tr
Many major mechanical issues for this vehicle 1) 6th cylinder head on the new penstar engine needed to be replaced 2) wind air leak causing whistling in the cabin 3) serpentine belt shredded and cracked 4) belt tensioner was binding and needed to be replaced 5) major vibrations- intake and exhaust phasers shorted 6) motor mounts worn 7) vibration got worse motor mounts trans and exhaust had to be remounted. *tr
Really have 3 issues with this vehicle. the first is that the engine began to tick noticeably at around 5000 miles, sound definitely coming from #2 cylinder. was initially told not to worry, noise was normal, oddly it did not tick previously. the short story is that it set a p0302 code at around 12,000 miles. chrysler did not authorize a rental and the dealer was less than cordial. they put the thing back together and damaged an emissions valve, so more delay. get the vehicle back, ran silent for 2,000 miles, the tick is back. now at 19,000, no code yet, but i fear its coming. problem #2, exhaust smell, get it nearly all the time, especially under load, no resolution yet. problem #3, wet carpet on drivers side, no resolution yet. oh, i forgot to mention, there is a fourth, i have just installed the third windshield in less than 6 months. its not the quality of the glass, its the steep angle of the windshield, but that's what you get when you buy a wrangler. i have been loyal to us brands, this is our 32nd new vehicle, won't by a wrangler again. *tr
2012 jeep wrangler started to have engine tick. took to 2 local garages, and they would not work on it. one said it was a chrysler restricted warranty work the other it was within the normal sound of the engine. it did not make ticking sound when purchased. i contacted chrysler to register a complaint and they said they had no idea that there was anything wrong. i had to take back to purchase garage where i had to push for it to get fixed. that was november. engines in some of the 2012 jeeps had a valve cut wrong and chrysler will only send out 1 valve per engine per week. my mileage has dropped and the ticking is worse. i have also noticed a bad "miss" when at idle. i was told it was ok to drive. it is getting worse. it is scheduled to go in the second week of january to get fixed. i have yet to hear anything from garage to let me know the part is in. i had 4 other jeep wranglers before me getting the part in to be fixed, and was told it was going to take a week or two at the garage. i only have 9200 miles on the jeep. *tr
Drivers side cylinder head ticking noise that 2012 pentastar based jeep wranglers have. chrysler has extensive knowledge of this issue and makes you run through hoops to get resolve. this is the potential cause of fires and engine malfunction that they are aware of and refuse to fix it immediately. this is a hazard to all owners and should be seriously addressed. *tr
I bought my 2012 jeep wrangler unlimited sport in november 2011. it was working just fine until the summer of 2012 when my wipers would turn on all by themselves for a few seconds, and then off again. this happened several more times during the summer. in addition, the radio would just power off. the only way it would come back on was to hit the top of the dash and it powered back on. took it in and they flashed a module which stopped the wiper issue but not the radio problem. this was july 2012. after that in same month, i noticed an engine light came on solid. took it in, they reset it saying it was a cylinder #2 misfire. people on wranglerforums.com were talking about it too (see jk section and look for "ticking pentastar" thread). it was the biggest thread actually. apparently, over a hundred owners on just this site alone had to have their head replaced. wtf? the light came back on a couple days later so i took it back in. they confirmed the same result and told me they would order a new head. the local dealer here in savannah (hoover) told me it was in. took in the jeep and they said it would take 2-3 days. big lie. after 3 days, i called to get status and they told me it would be 2-3 weeks!!! there were several people in front of me with same issue and only one guy fixing them. with a major issue like this on a brand new vehicle, this calls for a class-action lawsuit. i get small glitches happening but a new head??? they did not change anything on the 2013's so this will likely be a huge headache for jeep. be warned!!!! *tr
Tl* the contact owns a 2012 jeep wrangler. the contact stated that exhaust fumes were emitted into the vehicle. the vehicle was taken to the dealer who was unable to diagnose the failure. the manufacturer was made aware of the failure who stated that they would investigate further. the failure mileage was 125 and the current 1,474. updated 10/3/12 *cn updated 10/05/2012*js
I had bought my 2012 jeep wrangler with 2200 miles on it. i took my 2012 jeep wrangler to the dealership for an oil change at 3000 miles when i noticed after the oil change i heard a ticking coming from the engine. i drove it around thinking it might go away until after 1000 miles it did not. i took it to the dealership june 15th at 9:00 in the morning and spoke with a mechanic, manager, and my salesperson said, since it had only been a few weeks since i bought it. the manager told me they had 4 jeeps in there they had to do repairs on with the no.2 cylinder. he told me not to worry until it threw a code. i have been looking online at youtube and forums, and my case is not the only case. there are other people out there with these new 2012 jeeps who are having the same problem and it all has to do with this pentastar engine that chrysler has released for 2012. *jb

Vehicle developed an audible ticking from the left hand side of the engine which is present at all times, increasing with engine speed. intermittent loss of power while driving. *tr
Engine ticking coming from driver's side. took it to one dealer and the technician confirmed the tick. dealership refused to act. took it to another dealer and service tech told me that chrysler was aware of the problem but that repairs were on hold. took it back to that dealer and service employee denied any knowledge of a problem. ticking has gotten worse and engine power is decreasing. *tr
My 2012 jeep wrangler suffers from the common and well document "engine tick". i have had the tick for a least a few thousand miles. i might have had the tick since day one but never noticed it because this is my first jeep and quite honestly didn't know how the engine was supposed to sound like. *tr
The check engine light came on ,, took to dealer and they had to replace both heads. and one of the heads they put on was bad and i am still waiting for them to get another head and i hope it will be a good one, my jeep has been at the dealer for almost 2 mo. and i still don't have it back yet and its costing me a lot of money to rent a car. i will trade it in this year if i do get it back,,, looking at a gmc 4/w/d. *tr
My 2012 jeep wrangler sahara 2-door with automatic transmission exhibits the following issues: 1) valve train ticking noise. this developed after a few months of ownership (bought november 2011) 2) sluggish acceleration and automatic transmission shifting when vehicle is cold. it does improve as vehicle is warmed up after driving it for 5-10 minutes, and by then the vehicle seems to operate normal. 3) i sometimes feel a thud or vibration coming up from the steering wheel. it almost feels as something is loose in the front-end. this happens sporadically. this started happening just recently. i am going to discuss these issues with the chrysler dealership when i take it for the first oil change. *tr
Engine developed a ticking sound on driver's side engine bay. sounds like engine is missing or tapping on driver's side. loss of power/stalls more common now. took vehicle to chrysler and they say that my engine is just "loud" compared to all other 2012's and that it's normal. they told me to just drive it until it fails and then bring it back in because chrysler corporate will not allow a dealership to work on the engine and fix it until a failure occurs. so, now i am stuck with a 3 month old 2012 wrangler waiting for it to breakdown on the side of the road before the dealership will fix the known issue. mechanic says "that doesn't sound right" when i took it in. mind you i took the wrangler into two dealerships at this point for multiple opinions. both agree the jeep will fail and to just "wait" until it does because they are told by chrysler to not work on faulty wranglers with the new pentastar engine until the engine completely fails. real proactive on that decision chrysler. i'm not looking forward to the day power is lost when i'm on the highway or crossing train tracks. thanks a lot for putting my life at risk over a known issue yet not acting on the known fix. both dealerships claim they know heads are being replaced when this symptom is found on 2012 wranglers. that's all i'm looking for, fix what was not built correctly in the first place like others. *tr
Engine has ticking sound from the left side of the engine and continues to. chrysler and jeep complain this ticking is "normal valve noise". but, i have heard other engines of the same year and they do not have this sound. it appears to affect quite a few people from research as well. engine also feels like it stutters when reversing. *tr
Noticed a very prominent ticking noise coming from the drivers side of engine. occurs at idle and gets more pronounced when increasing speed while in park. notified the dealer and jeep spent three days at dealership. the service advisor who had 23 years of experience told me when he heard it that it definitely was a lifter problem. so i called chrysler corp and received a claim number. to make a long story short, i was told that all the pentastar engines made a loud ticking noise from the drivers side and this was a normal variant. was told that it was in the design of the left exhaust manifold and they all made this noise. after much talking between chrysler corp and the dealership i was told to come and pick up my jeep, nothing would be done. i have a friend who is a dodge mechanic and was told that the pentastar engines are having multiple problems with the left head and cam phaser are going out... i am concerned that the engine will catch fire or stall out on the freeway. *tr
