The bZ4X is Toyota's first mass-produced full-electric car.

TOKYO -- Toyota Motor Corp. will recall 2,700 bZ4X crossovers, its first mass-produced electric vehicle, because of a danger that wheels could come loose.

The world's largest automaker by sales submitted the recall of the bZ4X models to Japan's transportation ministry.

Of the 2,700 vehicles, 2,200 were earmarked for Europe, 260 for the United States, 20 for Canada and 110 for Japan, Toyota said.

Toyota is advising the 260 U.S. customers who have already taken delivery to park their vehicle immediately and contact any Toyota dealer to pick up their bZ4X. The dealer will provide a loaner vehicle free of charge until a remedy is available. However, Toyota said no remedy is available at this time.

Subaru Corp. also said Thursday it was globally recalling about 2,600 units of the Solterra, its first all-electric vehicle jointly developed with Toyota, for the same reason.

Sharp turns
Japan's safety regulator said sharp turns and sudden braking in the cars could cause a hub bolt to loosen, raising the risk of a wheel coming off the vehicle. The regulator said it was not aware of any accidents being caused by the defect.

The safety regulator said it was advising drivers to stop using the vehicle until a more "permanent" repair measure was in place.

Well what can you say, l thought they had tab washer that were peened over/split pin, maybe they could drill a hole in nut and wire lock it as well as belt and braces measure.


Reminds of that old favourite tune, hope Toyota get it's wheels falling off it's EV's problem recall sorted soon.

After having to replace the hood latch twice and the front wheel bearings, serpentine belt, and pretensioner every 50,000 miles on a Corolla that I bought new, it is not surprising to me that Toyota is having a problem with its lug nuts.
Maybe they should torque down their hood latches wit some of their spare lug nuts.

I know this is serious as people can get hurt, but at the same time I find it funny that the wheels can come off.
So what's a little freewheeling between friends? Folks make a mountain out of a molehill!

It's not a bug, it's a feature.

Indeed, glad you recognized how ingenious this actually is. Toyoter, as usual, is numerous steps ahead of the competition. 👽 It's almost unearthly.

This kind of thing happens to every manufacturer at one time or another. Still ... it's good when it happens to a Consumer Reports favorite.

Why doesn't Toyota just have a dealer service tech run out there with a torque wrench to tighten the lug nuts? Or am I being overly simplistic?
Now that's just crazytalk! Why on earff would you want to adjust the lug nuts to spec? Crazy!
Hey. How about a lock washer. More crazytalk. 😵

Gives new meaning to loose nut behind the wheel! 😆
Speaking of which, Toyota just announced that it has lots of potential loose nuts behind the rear wheels of 2022 Tundras. Specifically, nuts on the rear axle assembly:

PLANO, Texas (June 24, 2022) – Toyota is conducting a safety recall involving certain 2022 model year Tundra (including HEV) vehicles in the U. S. Approximately 46,000 vehicles are involved in this recall.

Vehicles in this recall have certain nuts on the rear axle assembly that can loosen over time, and, in some cases, fall off, potentially causing an axle shaft sub-assembly to separate from the axle. If complete separation occurs, this can affect vehicle stability and brake performance, increasing the risk of a crash.

For all involved vehicles, Toyota dealers will inspect and retighten the axle flange nuts. In some cases, axle-related components may be replaced based on inspection results.

Owners of involved vehicles will be notified by late July 2022.

Is the issue the lug nuts holding the wheel on or the single nut holding the hub on?
from the article:
Sharp turns
Japan's safety regulator said sharp turns and sudden braking in the cars could cause a hub bolt to loosen, raising the risk of a wheel coming off the vehicle. The regulator said it was not aware of any accidents being caused by the defect.
the only way a hub bolt comes loose is because it isn’t locked in place by a physical lock or thread locker.

So, a hub bolt would not be a lug nut, or the large nut holding the CV axle in place in the hub. It would be one of the bolts on the back side of the spindle holding the hub to the spindle. There are usually 3 of them back there, and the hub is pulled into the spindle in a somewhat press fit. The fix would be some lock tight and making sure the bolts are torqued correctly.

Just had a second thought after the above post. They could be using lug bolts instead of the more traditional studs and lug nuts. Some cars have used them down through the years, mostly foreign brands. If that's the case, the fix would be change to studs and lug nuts.

Uhh, duh, HUB nuts. Just go to the Hub Nuts Store, probably one near you. Obtain the necessary Hub Nuts, put them in your glove box, the car will know they're there and everything should be OK. :geek::cool:
