That's a fairly general statement. Any man-made product has the potential to fail or wear out due to component or pattern failure, or lack of maintenance, etc. Not necessarily a design or workmanship issue. The NBS trucks and SUVs have been some of the most reliable and by now the pattern failures are obvious and to be expected. Mine is old enough to drink, and I expect a certain amount of preventive and corrective maintenance as the years go by. What's a reasonable expectation for trouble-free operation for a vehicle that's changed hands a few times and has seen miles and miles of rough roads and possible lack of maintenance?
