Motor issues revealing itself?

I bought a '13 Rubicon w/ 4:10 in August '12 with 4 miles on the odometer. We drove about 200 miles various roads never going over 55 mph then drove 9 hours to Tennessee smokey mountains (from nw pa). I got 23 miles/gallon exactly on that trip. During the Tennessee trip we went to coal mountain ohv park and did some mild off roading, low gear, lockers, sway bar... There was 700 miles on the odometer. I notices the hood got extremely hot to the the touch while climbing mountain hills in low gear but my temps stayed normal... 2 years later, I get 15mpg on my town roads and I barely get 18mpg on the highway, I went as far as to get sahara tires to alleviate friction from the rubicon mud/terrain aggressive tread. I now have 22,000 odometer and When I start my jeep, it rattles like crazy for 5 sec and a light colored smoke comes from the tail pipe... There seems to be clattering noise when I'm on an incline and the torq converter is in overdrive.... On my very first oil change done at the dealer, they did some kind of computer flash, that's when I lost a few mpg... When I told the dealer I was losing mpg he asked if I had 4:10's and blamed the decrease on that. What should I do here???

So these sound like symptoms to a problem? Just curious, I am mechanical, I know the difference between injector noise and lifter rattle... The rattle goes away once the lifters fill with oil, but I didn't think newer style lifters were supposed to drain oil...? I'm not sure with these newer power plants... Many people on here told me it's common to smell coolant from wranglers... All I smell is coolant every time I walk past the front of the jeep... I was hoping for more then one reply... Find a new dealer isn't very good help, especially since I live in a rural area and all the dealers are small... If these symptoms are concrete pointers to a problem with my head, I need to fight the way these dealers have a quick answer for every problem...

I hate to say drive it till it gets worse, but with a full warranty and a trip to the dealer that records all of your complaints i.e. building a history, if something bad happens it would be easier to get covered. I know the dealer my dad and I use has told him with his 13 with A/C issues that they cant duplicate that because he has been in before, even if he is out of warranty and has issues they will take care of it if it fails 100%. You have power train coverage until 5/60k. I would keep an eye on it and record if you have to add anti-freeze or oil in between normal service intervals as more evidence for your dealer of something going wrong.

What color is the smoke? Blue is oil, white is coolant, and black is excess fuel.

It looks whiteish, when I asked the dealer, he said it is steam from the first start of the day... I always see and hear the lifters because I have auto start, I usually push the start button as I get close to my jeep, that's when I see the smoke and the lifters are just loud, especially the drivers side.

Another issue I failed to mention, there are times when I swear I started my jeep and it's is running, but when I put it in gear, nothing... It's like I didn't start it... I don't even hear it stall. I don't know if it's in my head, or if it truly didn't start...

Oh, I didn't buy the full warranty... They told me it's a 3yr/36,000 mile warranty.

As to point 1: keep an eye on your antifreeze. If its truly burning anti freeze enough that you see smoke, you will slowly see it getting lower and lower.

As to point 2: I have caught myself with my remote start a few times starting it, getting in, putting it in gear without putting the key in(or putting the key in, but forgetting to turn the key to run) and the engine shuts off. Might be what is happening there.

Just something to consider but your break in process was not the best. Holding 55 steady for 9 hours and then driving off road was the best thing for your new engine. I assume you suspect it, otherwise you wouldn't have mentioned it.

My hood never got extremely hot from the engine in spite of driving in 100║+ all summer when I purchased it.

search pentastar 3.6L head issues. 12-13 owners just got a 10 year 150000 mile warranty extension on the left head due to the issue.
