Nearly 200,000 Toyota Supra and BMW Z4 sports cars – and other more popular BMW models – have been recalled in the US, and some Australian vehicles are also likely to be caught up in what has now become a global issue.

The US product safety recall for both models is due to a potential starter motor defect which could see the BMW-produced 2.0-litre turbocharged four-cylinder petrol engine fitted to some Supra coupes and Z4 roadsters switch on by itself, or even catch fire.

This means Australian Supra owners will not be involved, given only the 3.0-litre inline six-cylinder engine is offered in the Japanese coupe here – but the 2.0-litre ‘B48’ turbo-four is available in the local Z4 lineup.

The risk includes potential overheating, leading to a short-circuit and potential fire outbreak
