2012 JKU grey smoke
I belive the autos had trans cooler issues and for the heads the 3.6 had a ticking issue on the drivers side head due to bad milling from the factory.
I thought that the bad heads were only on the 3.8s. I know they had bad lifter problems and you always had to make sure you had oil in them. And I thought they fixed a lot of the 3.6 issues with the 2013 jeeps.
Bad lifters. Mine has one. With the fun loving van motor it like to burn 1qt of oil every 3k. Many people will say this is not normal blah blah blah. Personaly it still runs with the tick. Every time you put in gas check your oil. Odds are you ran it low for too long and it burned a litter. If you got it brand new you have the life time warenty. You just have to prove you or somebody did the oil changes. And before you take it in to the dealer make sure you check the oil and its full. And don't take crap from them. It's a bad motor. They have to replace it.
Just took it in because there was no oil on the dipstick at all. They were completely confused so now the fun of oil consumption test starts now they want me to come in every 500-1000 miles i will keep y'all posted.
Man. I hope for your sake they don't void your stuff because you drove your jeep with no oil in it.
