Harman International Industries Inc. audio systems used in Audi and Bentley vehicles don’t have the same vulnerabilities as the technology in the Jeep Cherokee that was hacked remotely, the U.S. Department of Transportation said Saturday.
The regulator closed a months-long investigation into Harman’s radios supplied to automakers other than Fiat Chrysler Automobiles NV, which makes the Jeep Cherokee. The probe followed a recall of about 1.4 million vehicles to update radio software announced by Fiat Chrysler in July.
“There does not appear to be a reason to suspect that the infotainment head units Harman supplied to other vehicle manufacturers contain the vulnerabilities identified by” Fiat Chrysler, the department said in a statement.
Fiat Chrysler’s recall related to the audio systems was the first formal auto safety campaign in response to a cybersecurity threat. Executives from 15 auto companies met with Transportation Secretary Anthony Foxx last month to discuss specific industrywide actions to prevent cars from being hacked.
