Feds Say No Need to Recall Tesla's One-Pedal Driving Despite Petition

Feds Say No Need to Recall Tesla's One-Pedal Driving Despite Petition

The U.S. National Highway Traffic Safety Administration (NHTSA) has declined to order a recall of Tesla’s one‑pedal driving system, concluding there is no systemic sudden unintended acceleration problem. The agency reviewed a 2023 petition from a Greek engineer that sought to compel a recall of over two million Tesla vehicles built since 2013. Technical analysis shows the feature relies on lift‑off regenerative braking rather than a defect that would cause a parked car to surge forward. Consequently, Tesla avoids costly remediation while the broader EV industry sees the regulator’s stance as a benchmark for future safety claims.
