Toyota is recalling about 1.03 million hybrid models, including the Prius and its plug-in variant, due to a wiring issue that could pose a fire risk.
The vehicles were produced between June 2015 and May 2018.
Half a million of the affected models are in Japan.
Some 219,000 cars believed to be affected across Europe, the Daily Mail reports. Another 192,000 models will also need to be called back in the US, though it is only Prius versions in North America that are affected.
The plug-in C-HR compact crossover SUV sold in Japan, Europe, Australia and New Zealand is also included in the recall which relates to the wire harness assembly that connects the hybrid power control unit.
A portion of the wire harness could contact the cover at this connection and wear over time, causing an electrical short circuit, which can generate heat,” Toyota says. “If sufficient heat is generated, there is an increased risk of a vehicle fire.”
Toyota spokesman Jean-Yves Jault says the issue led to one incident of a short circuiting in Japan which produced smoke from the vehicle.
Affected models will have a protective sleeved added to the engine wire harness if the wire core is exposed, or the harness replaced if required.
The global recall will be the biggest for Toyota since it had to contact owners of about 2.9 million cars with faulty Takata airbags from 2016 onwards.
