On 10/24/2026 at approximately 6:10 PM, I was driving this 2023 Nissan Leaf SV Plus (under 20,000 miles) southbound on I-575 in Woodstock, GA, with Intelligent Cruise Control and e-Pedal both engaged. When traffic ahead slowed, the vehicle did not slow down. I applied the brake pedal, but the vehicle did not decelerate as expected, and it struck the rear of the vehicle ahead. No warning I am aware of preceded the event. Earlier on the same drive, the vehicle also did not slow as expected when I braked for a yellow light, until I pressed the brake pedal very hard. No injuries. The vehicle sustained significant front-end damage. Police report: Woodstock PD Case WO26-003692. The vehicle is being preserved for inspection, including Event Data Recorder download. I will submit diagnostic and EDR results when available.
