Toyota Motor said on Thursday it would recall 2,700 of its first mass-produced electric vehicles (EVs) for the global market because of a risk the wheels could come loose.

According to Reuters, the automaker submitted the recall of the bZ4X SUVs 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, the company said.

Subaru also said on Thursday it was globally recalling about 2,600 units of the Solterra, its first EV jointly developed with Toyota, for the same reason.

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

The regulator advised drivers to stop using the vehicle until a more “permanent” repair measure was in place.

All of the cars recalled in Japan had not yet been delivered to customers as they were meant for test drives and display, spokespeople for the automakers told Reuters.

“We sincerely apologise for any inconvenience this causes you,” Toyota said on its website. “We would have repaired it as soon as possible, but we are investigating the details.”

A Toyota spokesperson told Reuters not every model was subjected to the recall but declined to say how many it has built overall.

For Subaru, most of the vehicles were for dealers and none were delivered to customers in the US, a spokesperson told Reuters.

The recall came less than two months after Toyota, a relative latecomer to the EV market, rolled out the electric SUV, bZ4X, to the domestic market, albeit as a lease-only option.

Toyota’s unit that offers the leases, KINTO, has cancelled promotional test-drive events planned in three Japanese cities for safety measures, the report said.
