I'm a little concerned now lol. I replaced the lines last May because they were leaking... everything else on the car is up to date. No leaks, rattles or maintenance... I guess truth is you just really can't foresee something like that happening. I bought it in November 2013 and now 17,000 miles later, I've put in a new fuel filter, done the intake gaskets, injector rings, both axle seals, transmission flush, transmission lines twice now, oil pan gasket, valve cover gaskets, new tires, new snow tires, new rear stuts, new control arms, new control arm bushings, new ball joints, a new wheel bearing, new front brakes, new front calipers, a wheel bearing, a coolant flush, brake flush, an outer tie rod end, water pump, new alternator, new battery, new serpentine belt... and lots of oil changes and alignments.
