Jaguar Land Rover is recalling 44,000 cars in the UK over carbon dioxide emissions.
Regulators found 10 models were emitting more of the greenhouse gas than they had been certified to emit.
The car maker will contact owners to arrange repairs, a JLR spokeswoman said.
The affected models are:
- Some two-litre 2016 to 2018 Land Rover Discovery and Discovery Sport cars
- Certain two litre Range Rover Evoque, Sport, and Velar cars
- Jaguar E-Pace, F-Pace, F-Type, XE and XF cars.
Most models are petrol, while some are diesel.
The repairs - which will be free - could include software updates as well as physical alterations, and some Range Rover Evoque models will need new tyres, a JLR spokesperson said.
In a statement, JLR said: “Affected vehicles are being rectified to ensure the correct CO performance is dependably achieved. The modifications made to affected vehicles will be made free of charge and every effort will be made to minimise inconvenience to the customer during the short time required for the work to be carried out.”
