I have a Lincoln Navigator SUV. Before 100,000 miles it needed two coil packs, a water pump, brakes, O2 sensor, ball joints and a front wheel bearing. Not all of it was under warranty. So yes they do need work before 100,000 miles. Are you going to call me a liar now?
That’s called not doing your research. Navigators have a terrible reputation. You bought a piece of crap that 10 minutes of googling would have warned you was a piece of crap. There’s always going to be junk out there, but in this modern world where we have this “over engineered” technology called the internet junk is more avoidable than ever before. Rule 1: don’t buy American, the big 3 make crappy cars.
