On the other hand anecdata, I had a 13ish year old 4Runner with only about 70K miles lose a transmission line on me a couple years back. The dealership shrugged and said maybe it was a chip on the coating from a piece of gravel. Though it may well have been a manufacturing defect. In any case, ended up having to nurse the vehicle home and basically nurse it 2 months until I could get a new Honda.

Which I actually like a lot better. The 4Runner is a very old platform. Other than the infortainment system, a rental I coincidentally had a couple years back was basically identical to the fairly poor handling SUV I had for 10+ years.

Why did the transmission line require replacing the vehicle? I've replaced them on a cargo van...it was cheaper and easier than a pair of rear drum brakes, a normal piece of routine maintenance

The transmission was drivable but damaged because it was a bad leak. Given its age and some body damage, it didn't make sense to repair--and I got a ridiculously good trade-in anyway.
