Certain vehicles built with Electronic Stability Control may cause the brake lights at the rear of the vehicle to illuminate during an automatic traction control (ATC) event. Brake lamps illuminating with the activation of ATC do not meet the intent that brake lamps provide a steady light when intentionally slowing or stopping the vehicle. Brake lights not illuminating as expected may not accurately signal to other motorists the intent of the driver, leading to an increased risk of a crash.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10187987-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10187987-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10187987","components":[{"id":"driver-assistance","name":"Driver assistance","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"ALTEC","model":"AERIAL DEVICE","year_from":2016,"year_to":2018,"match":null,"vehicle_ids":[]},{"make":"ALTEC","model":"DIGGER DERRICK","year_from":2014,"year_to":2014,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
