I wish there was a "continually improved" model of car where they gradually tweak every part that fails over time, instead of just throwing it all out with an "all new redesigned" model every 10 years (with all fresh weaknesses).
I don't think GM makes passenger versions anymore, but the cargo vans are still super common in my area (southern Ontario).
For example, today I replaced a front wheel hub-bearing on a FWD car. These are designed with a cast steering knuckle that the axle goes through. The bearing assembly is mounted on the front of the bore, the axle goes through the bore into the hub-bearing from the back, and there's a little seal on the back of the bore that the axle rides on.

The weakness is that water inevitably gets into the bore around the back seal (since the axle moves around a bit) and the only way out is through the bearing out the front. It rusts out. Nobody has improved this design for the past 50 years, as far as I am aware. Perhaps a weep hole? Perhaps they need to be completely filled with grease?
But Henry Ford lost this argument 90 years ago when GM proved that styling newness trumps all other factors when it comes to sales.
