Toyota bZ4X Wheel Detachment Recall: What Owners Need to Know

In June 2022, Toyota did something automakers rarely do: it told bZ4X owners not to drive their cars at all, before a repair even existed, because the wheels could come loose and detach while driving. This wasn’t a minor paperwork recall — it was one of the most urgent safety actions an automaker can issue, and it landed just months after the bZ4X, Toyota’s first mass-market EV, went on sale. Here’s exactly what caused it, how many cars were actually affected, and how to confirm your specific bZ4X was part of it and got fixed.

The scale of this recall was tiny compared to most — here’s the quick version.

Symptom	What You Notice	How Urgent
Hub bolts loosening (the recalled condition)	Unusual vibration, a wheel that feels loose, or noise from a wheel, especially after hard cornering or braking	Extremely urgent if unrepaired — Toyota’s own guidance at the time was to stop driving entirely, not just book a service appointment
Vehicle outside the tiny recalled population	Built outside the March 30 to April 21, 2022 bZ4X window, or already received the free repair	Not affected — but confirm via VIN check rather than assuming
Unrelated wheel/hub noise on a car outside the recall	Similar symptoms, but production date and VIN don’t match the recall	Still worth inspecting, just not this specific recall

If you own an early 2023 model year bZ4X and have never confirmed this recall was completed on your specific VIN, stop assuming it was and check today. A wheel detaching while driving causes a loss of vehicle control, and Toyota’s own recall filing estimates that 100% of the vehicles in the affected population have the defect. Whether it progresses to a wheel detaching depends on driving conditions, but the faulty parts are on every car in that narrow population.

What’s Actually Failing

Toyota’s recall filing describes a chain of small manufacturing issues that combined into a serious one. The hub bolts holding each wheel on had a higher-than-expected coefficient of friction on their surface, which meant they didn’t achieve the clamping force Toyota’s design intended when they were torqued during assembly. Under certain driving conditions — ones that expose the bolts to higher operating temperatures — that friction coefficient can change further, relaxing the torque even more. On top of that, the wheels on affected vehicles had excessive roughness on their contact surface and bolt holes that weren’t properly aligned, both of which reduced the overall resistance holding the wheel in place. Combined, these conditions could let all of the hub bolts on a single wheel loosen to the point of detachment.

Toyota’s investigation traced back to a field report from Taiwan in May 2022 describing a front-left wheel separating from a vehicle. The affected wheels were supplied by MEIDOH CO., Ltd. in Japan.

Is This Covered by a Recall or TSB?

Yes — this was a formal, urgent NHTSA safety recall, Campaign No. 22V-444, filed by Toyota Motor Engineering & Manufacturing. What surprises most people researching it is how small the actual population was: Toyota’s Part 573 filing lists just 661 vehicles total as potentially involved, and that figure covers both models named in the filing: 2023 model year bZ4X units built between March 30 and April 21, 2022, and 2023 Solterra units built between March 30 and June 3, 2022. The filing also notes that not every vehicle built in those windows was sold in the US. Toyota’s own filing states Subaru confirmed no Solterra vehicles had yet been sold to dealers or retail customers, so the cars already in owners’ hands when the recall landed were bZ4Xs. The Solterras were repaired before delivery instead, and that repair led to a second recall of its own, covered below.

Toyota estimated 100% of the recall population had the defect, an unusually high figure for a recall. The filing is careful to add that whether the defect actually leads to a wheel detaching in any individual case depends on many variables. In other words, every car in the population had the faulty parts, not every car was going to lose a wheel. Toyota began notifying customers on June 23, 2022, with formal owner letters required by August 22, 2022. This recall predates a lot of the bZ4X’s time on sale — it was one of the earliest, most consequential events in the model’s history, not a recent one.

Check your VIN at nhtsa.gov/recalls to confirm whether your specific bZ4X was part of the recalled population and whether the repair shows as completed — given how small and specific this population was, most bZ4X owners today have vehicles built outside this narrow window and were never affected, but if you own one of the earliest cars, it’s worth confirming rather than assuming.

How to Confirm It Applies to Your Car

• Check your VIN at nhtsa.gov/recalls — this is the definitive way to know, since Toyota identified the affected population from precise manufacturing records rather than a broad model-year range.
• If you bought your bZ4X used, specifically ask the seller or a Toyota dealer to confirm recall 22V-444 shows as completed on that VIN’s history, rather than assuming a previous owner handled it.
• Watch for unusual vibration, noise, or looseness from a wheel, especially after hard cornering or braking, though given how thoroughly this recall was addressed back in 2022, this is now a historical concern for most bZ4X owners rather than an active one.
• Call Toyota directly (1-800-331-4331) if you’re unsure and can’t access the VIN lookup.

Repair Cost

Free. Toyota’s remedy replaced both the hub bolts (with a newly designed bolt that includes a washer) and the wheels themselves with improved ones, at no cost to the owner. Toyota’s filing notes the repair fell well within the active period of Toyota’s New Vehicle Limited Warranty for every affected owner, so there was no gap where an owner would have had to pay out of pocket.

Can You Keep Driving With It?

If your bZ4X was part of this recall and the repair hasn’t been confirmed complete, no — Toyota’s own guidance at the time of the recall was not to drive the affected vehicles at all, which is a stronger warning than the “get it checked soon” advice that applies to most recalls. If your VIN check confirms the repair was completed, or confirms your car was never part of the recalled population in the first place, there’s nothing outstanding here and ordinary driving is unaffected. Given how small and specific this 2022 recall population was, the practical reality for most current bZ4X owners is that this is a piece of the model’s history worth knowing rather than an open risk on their specific car — but that’s worth confirming with an actual VIN check rather than assumed.

What About the Subaru Solterra?

The Solterra shares the bZ4X’s platform and was named in the same recall, but its story went further. Its hub bolts were replaced at port before any Solterra reached a customer, and in 2023 Subaru recalled 1,182 of those cars again because a contractor team had under-torqued the replacement bolts. If you own or are shopping for a 2023 Solterra, our Subaru Solterra wheel detachment recall guide explains how to check both recalls against your VIN.
