Hundreds of popular cars – including four of the five best-selling models in the UK – are susceptible to “keyless theft”, new research claims.
Consumer group found the Ford Fiesta, Volkswagen Golf, Nissan Qashqai and Ford Focus were all at risk.
Thieves are increasingly thought to be using technology to bypass entry systems on keyless cars.
But industry body the Society of Motor Manufacturers & Traders (SMMT) said “new cars are more secure than ever”.
ADAC tested 237 keyless cars and found that all but three were susceptible.
The latest models of the Discovery and Range Rover, and the 2018 Jaguar i-Pace, all made by Jaguar Land Rover, were found to be secure.
Of the top-selling cars in the UK, only the Vauxhall Corsa was deemed safe because it is not available with keyless entry and ignition.
“Thieves have been using keyless theft for several years, but manufacturers continue to make new models that can be stolen in this way, meaning there is an ever-larger pool of vehicles for thieves to target,” Which? said in a statement.
