Kia customers are being targetted by internet hoaxers who claim that former purchasers have won a prize in a competition.
Unfortunately, the email is a con to persuade recipients to give away personal information, such as bank account details.
Stephen Kitson, communications director of Kia Motors (UK) Limited, said: "We have never run an e-mail lottery, we are not running an e-mail lottery and we are unlikely ever to run an e-mail lottery, pure and simple.
"It is clear from the language used in the e-mails that although the contact details suggest they are based in the UK that may not be the case. We are currently working with various authorities to try and trace these people and to stop this scam, but members of the public receiving these e-mails should be aware of this practice and should not provide any personal details under any circumstances."
Customers who suspect that their bank account details have been compromised should forward the email to the ‘phishing’ department of their bank immediately.
