EPA Administrator Lee Zeldin has hinted that the agency plans to make an announcement this week regarding the future of automatic start-stop technology in vehicles. Zeldin stated on social media that "countless Americans passionately despise" the feature and that the Trump administration has "heard your calls" for change. While the details of the EPA's plans are unclear, it's possible they could eliminate the off-cycle credits automakers currently receive for using start-stop systems, or make the systems easier for drivers to disable.

Why it matters

Start-stop technology, which automatically shuts off a vehicle's engine when stopped to save fuel, has never been mandated in the U.S. but has become ubiquitous as automakers seek EPA credits. However, the feature is widely disliked by consumers, who often find it intrusive and frustrating. The EPA's potential move could significantly impact the future of start-stop systems in the American automotive market.

The details

Start-stop systems work by turning off a vehicle's engine when it comes to a stop, then restarting it when the driver is ready to accelerate. While the EPA previously supported the technology's ability to improve fuel economy by up to 5%, automakers have only installed it to receive off-cycle credits, not because it's mandated. Most new vehicles sold today also allow drivers to easily disable the feature.

  • On May 2025, EPA Administrator Lee Zeldin said he would eliminate start-stop systems under the Trump administration.
  • On February 11, 2026, Zeldin hinted on social media that an announcement about start-stop systems is coming this week.
