My second JK in six year. The first was a 2011, with the 3.8 six. My mechanic always told me to sell it before it turned 90k miles because that engine was notorious for leaking oil after that. I never got the chance to sell it as I was rear-ended at a light and it was totaled. Second one is my 2013 with the new and improved 3.6 six. So far, at 66k miles, I've had one front brake caliper freeze up and had it replaced, and just had the engine thermostat replaced. I call that a very reliable vehicle! I went and replaced all the lighting with LED which looks cool and should last forever. I also installed a Roar Pedal device which really helps to make it run like a sports car. The acceleration is really dramatic with the Roar. Living in Florida lets me take it on the beach which is a big plus as well. Overall, I hope I can keep it for many more years.
