When you apply some pressure to the brake pedal, this feature of the system can automatically help further reduce speed if sensors detect the possibility of a crash. Due to incorrect software programming, there could be a delay in the activation of pre-collision brake assist, resulting in less overall vehicle speed reduction. However, the other features of PCS (the pre-collision warning and pre-collision braking) are not affected by this programming error.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10202498-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10202498-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10202498","components":[{"id":"brakes","name":"Brakes","parent":null},{"id":"electrical","name":"Electrical system","parent":null},{"id":"software","name":"Software","parent":"electrical"}],"codes":[],"topics":[],"vehicles":[{"make":"TOYOTA","model":"PRIUS","year_from":2021,"year_to":2021,"match":"exact","vehicle_ids":["2021_toyota_prius"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
