Don't you think it's odd to have a miss at only 71K and have to change the plugs? I thought that plugs were good for 100K since the 90's. Do you have a catch can and do you drain the intercooler via a weep hole or other means? Of course, IN is not nearly as humid as SE Texas (think Houston) so you may not have the same problem we have.
Wow, sorry to hear. My 2012 has 71K and still original brakes. I changed the plugs at 60K for a miss and it fix it. Other than that a set. Of tires around 40K and a heater blower control module, $75, is it.
I would definitely buy again.
