Reliability issues- cylinder misfire/battery

Hey guys, I have a 2012 JK with 18.5k miles and already its killed one battery, had a cylinder misfire (apparently a known issue), and had to have the radiator replaced due to a leaky seam. Everything's been covered under warranty but I'm fearful of the future. I've only had it for a year and serviced it regularly, never even taken it on anything harsher than a bumpy dirt road yet. What's up with this? My 2002 TJ has never had anything wrong with it and we bought it new

I know Jeeps have a shakedown period in which everything that's going to break will break, but engine/battery trouble is kind of ridiculous for being a year old. Is this going to keep happening?

NO, there seem to be some debate on just how many 2012 jeeps have bad heads. So much of what you read online is BS it's hard to tell. I use 2 different dealers both are huge Jeep dealers and sell a ton of new Jeep's 1 dealer told me Chrysler has figured out they have around 18000 bad heads due to a machining calibration error on 1 machine at it's engine plant of that number 6000 of those heads were used in other models.
As far as the batteries I started a thread on this the batteries are made in India and are junk very weak walling. I have had 2 of them go I replaced my last one with a Interstate I paid for myself not wanting to get stranded in a little town or in the middle of the woods. To date the batteries have not been changed and dealer told me many 2013's also have this problem along with several Toyota cars that use the same battery.
I have pounded the piss out of my 2012 jeep and have not had any real problems that I did not do myself and so far it's like the energizer bunny.
