House passes AM Radio for Every Vehicle Act requiring radios in all new cars
↗
The House approved the AM Radio for Every Vehicle Act, mandating that all new passenger vehicles include AM radio capabilities within two years, reigniting a bipartisan push that pits automakers against broadcasters.
Engineers will need to redesign vehicle audio systems to meet the new AM radio requirement, adding an estimated $3.8 billion in mitigation costs for automakers already dealing with EV interference challenges. The mandate forces manufacturers like Tesla, which removed AM radio from entry-level models, to reinstate the hardware, potentially affecting vehicle design and weight. The legislation also raises concerns about GPS redundancy and public safety communications.

The House passed the AM Radio for Every Vehicle Act, requiring AM radio capabilities to become standard in all new passenger vehicles within two years for large manufacturers.
Automakers face an estimated $3.8 billion in costs and must modify designs because EV motors generate interference that currently leads many manufacturers to omit AM radios, as seen with Tesla’s entry-level models.
Broadcasters and bipartisan lawmakers argue the mandate is essential for emergency information and public safety, citing scenarios where GPS failures could leave drivers without communication.
THE READ
What the cluster adds up to.
The House’s approval of the AM Radio for Every Vehicle Act introduces a concrete regulatory change, directing the Transportation Department to issue a rule that makes AM radio standard in all new passenger vehicles, with a two-year implementation window for major manufacturers. This legislative shift creates a new compliance deadline for the automotive industry. It marks a rare point of agreement among lawmakers, uniting figures such as Ted Cruz and Bernie Sanders. The act directly alters the technical specifications that vehicle designs must meet.
Support for the bill comes from broadcasters who have lobbied extensively, including John Catsimatidis and the National Association of Broadcasters, emphasizing the role of AM radio in emergency alerts and community news. They argue that the mandate safeguards public safety, especially if satellite GPS systems fail. Automakers, however, oppose the requirement, citing the financial burden and engineering challenges it introduces. The legislation thus frames a clear conflict between the broadcasting sector and vehicle manufacturers. This opposition highlights the tension between regulatory mandates and industry practicality.
Technical obstacles arise because electric vehicle motors produce electrical currents that can interfere with AM signals, prompting many manufacturers to remove AM receivers from newer models. A Center for Automotive Research study funded by the industry estimates $3.8 billion would be needed to mitigate this interference. Companies like Tesla have already eliminated both FM and AM radios from entry-level cars, meaning redesigns will be necessary to meet the new standard. Engineers must now integrate AM hardware while managing weight, space, and potential signal degradation.
The bipartisan nature of the bill underscores a unusual consensus on a niche technology, with nostalgic arguments such as Ted Cruz’s reference to Rush Limbaugh reinforcing cultural ties to AM broadcasting. While proponents stress the importance of emergency communications, critics note that alternative solutions, such as battery-operated radios, could address safety concerns without imposing costs on manufacturers. The outcome will influence vehicle design priorities, manufacturing costs, and the broader debate over the relevance of AM radio in modern transportation.
