U.S. safety regulators have determined that only Fiat Chrysler radios have a security flaw that allowed friendly hackers to take control of a Jeep.
The National Highway Traffic Safety Administration says it’s ending a five-month investigation into the vulnerabilities of automotive radios. The agency also said a recall of 1.4 million Jeep, Chrysler, Dodge and Ram vehicles closed the opening that allowed hackers to remotely take over a Jeep Cherokee.
The hack by security experts Charlie Miller and Chris Valasek touched off the investigation in July. They were able to change the vehicle’s speed and control the brakes, radio, windshield wipers and transmission.
The safety agency found that similar radios made by Harman International went to Volkswagen, Audi and Bentley, but that those vehicles have safety systems that would stop hackers.
