2011 Sahara 106xxx miles. Fluids on time, 1 rear brake light, rear brake pads, front still orig...yeah I don't get it either but well within spec. Of course I drive it like I'm 54...wait I guess being 54 really does make a difference. Replaced front LCAs w JKS and added fox steering kit. It's been on the beaches of NC, trails in Maine, high plains and deserts of Wyoming, mountain trails in Colorado and has covered every inch of I -95 a few times. Not to mention I 80/90/40. 3 sets of tires. BFG KM2s, Firestone ATs and now TOYO Open Country. I even thought about trading up to a 17 but just doesn't make sense at the moment. Jeep on!

I'll update my mileage...87000 trouble free. Other than brake pads and other routine maintenance, I haven't touched a thing.

85M+ uses a little oil between changes. No other issues. Oil cooler lines were replaced. Couldn't be happier.
