Fiat Chrysler has warned of problems with 1.4 million vehicles in the US after growing concerns that onboard systems are wide open to attack by hackers.
The safety recall comes in the form of a USB device that affected customers can plug directly into their car to update to the latest software.
The update applies to a number of models equipped with an 8.4in touchscreen entertainment system. These include the Dodge Viper (2013-2015), Dodge Challenger (2015) and a number of Jeep Grand Cherokee models (2014-2015).
Fiat Chrysler confirmed to V3 that the potential threat affects models available only in the US.
The firm said that hacking into its vehicles is a "criminal action", and that the company is unaware of any injuries, claims or accidents that have occurred as a result of the vulnerability.
"No defect has been found. Fiat Chrysler Automobiles US is conducting this campaign out of an abundance of caution," it added.
"Similar to a smartphone or tablet, vehicle software can require updates for improved security protection to reduce the potential risk of unauthorised and unlawful access to vehicle systems.
"Customers can either download and install this particular update themselves or, if preferred, their dealer can complete this one-time update at no cost to customers."
Fiat Chrysler has created a ‘system quality engineering' team to identify and implement best practices for car software development in the future.
The news comes after a report by Wired outlined how hackers discovered a zero-day vulnerability in a Chrysler Jeep Cherokee and were able to gain remote access to the vehicle's engine, air conditioning, radio and windscreen wipers.
Hackers Charlie Miller and Chris Valasek, who have been sharing their security research with Fiat Chrysler for nine months, found the vulnerability in the Uconnect connectivity system.
Uconnect is installed in a number of Fiat Chrysler vehicles, and is an internet-based feature that enables phone calls, navigation and even a WiFi hotspot.
The hackers are planning to publish a portion of their exploit to coincide with an upcoming event in Las Vegas.
"If consumers don't realise this is an issue, they should, and they should start complaining to carmakers," warned Miller. "This might be the kind of software bug most likely to kill someone."
However, Fiat Chrysler has spoken out against the release of any sensitive information.
"Under no circumstances does Fiat Chrysler Automobiles condone or believe it's appropriate to disclose 'how-to' information that would potentially encourage, or help enable, hackers to gain unauthorised and unlawful access to vehicle systems," the company said.
Meanwhile, BT announced a ‘hack testing service' for the connected car industry earlier this year called BT Assure Ethical Hacking for Vehicles.
"Vehicles are now connected devices, confronting manufacturers and suppliers with a whole new world of security challenges," said Hubertus von Roenne, vice president for global industry practices at BT Global Services, at the time.
Interconnected technology is increasingly being criticised for security vulnerabilities. Several problems were discovered recently in top smartwatch brands that revealed flaws in cloud-based storage systems and user authentication.
