The FBI and the US National Highway
Traffic Safety Administration have added their voices to growing
concerns about the risk of cars being hacked.
In an advisory note it warns the public to be aware of "cybersecurity threats" related to connected vehicles.
Last year Fiat Chrysler recalled 1.4 million US vehicles after security researchers remotely controlled a Jeep.
People who suspect their car has been hacked were told to get in contact with the FBI.
