Toyota is unable to come up with a fix

… for the mechanical problem that led to the recent recall of their new bZ4X EV. In the absence of a fix, they are offering to buy-back the vehicles. Very, very strange…

Edited to add…
As expected, Subaru has the same issue with their mechanically-identical Solterra model, and–similarly–they have no fix for the problem:

I’ll just keep on avoiding buying the first year of a new generation of car.
Let the early adopters be the guinea pigs.


Drive it until the wheels fall off.

This is incredible to see… The largest automaker can’t keep wheels on? What the heck??

Scrap the wheel bolts. Thread capscrews into the back of the hub with red Loctite and go back to lug nuts, increase torque, done.


This situation is not something that should mystify Toyota’s and Subaru’s engineers.


I wonder why the wheel bolt idea isn’t working, since it is common in many European cars? The most common method seems to be threaded studs pressed into the hub, and lug nuts holding the wheel on. One advantage to the stud/nut method might be that the nuts are further away from the brakes, and therefore not subjected to severe temperature changes. Seems however that if the EV uses regenerative braking, the brake heat should be less than w/regular brakes. So if it works w/a VW, why not this one? It’s a puzzle at this point. The only thing I can come up with, maybe the hub or bolt material properties is the problem. Evidence wise, from my penchant of finding stuff laying the street, rarely find wheel bolts, occasionally find wheel nuts, but those aren’t common either, except from big trucks.

Shame on you, Toyota! Nissan has it all worked out!


That’s what I’m thinking also.
