A new report by industry journal, Automotive News Europe, the European Union's Safety Gate Rapex claims JLR vehicles with 2.0-litre engines (both petrol and diesel) may emit "excessive levels of Carbon dioxide and may not conform with the certified condition".
The repairs may involved software updates along with physical alterations.
The UK-based luxury car-maker said on Thursday that it will contact the owners of the affected vehicles to arrange for free-of-charge repairs after regulators found 10 models were emitting more of the greenhouse gas than they had been certified to emit.
The issue was discovered by the Vehicle Certification Agency, which is a branch of the Department for Transport. JLR then informed the country's Driver and Vehicle Standards Agency (DVSA), which handles recalls, of the findings.

"Jaguar Land Rover must now act quickly to tell affected customers so that they can have their vehicles modified appropriately".
The European Commission's rapid alert system warned that JLR's cars "may emit excessive levels of Carbon dioxide and may not conform with the certified condition". Cars manufactured between 2016 and 2019 were recalled.
She said: "Consumers must be able to fully trust the claims of vehicle manufacturers, particularly after the emissions scandals of recent years".
Speaking with CarAdvice, JLR's local arm confirmed there are 1731 units affected in Australia - 958 Land Rovers and 773 Jaguars.More news: New Zealand mosque attacks: What we know so far
