Certain 2019 Cadillac CT6 equipped with engine RPO?s LSY or LTA, Chevrolet Silverado 1500 (New Model), and GMC Sierra 1500 (New Model) vehicles have a condition where the brake system control module (BSCM) may cause a service brake assist message to appear on the driver?s information center (DIC), and a service engine soon light to illuminate on the dashboard. This may cause the brake pedal feel to be different. The pedal travel will increase for normal/light braking applies. This is caused by a software issue where the motor position sensors do not correlate. Dealers will reflash the BSCM with updated software.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2019/MC-10159554-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2019/MC-10159554-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10159554","components":[{"id":"brakes","name":"Brakes","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"CADILLAC","model":"CT6","year_from":2019,"year_to":2019,"match":"exact","vehicle_ids":["2019_cadillac_ct6"]},{"make":"CHEVROLET","model":"SILVERADO 1500","year_from":2019,"year_to":2019,"match":"base","vehicle_ids":["2019_chevrolet_silverado"]},{"make":"GMC","model":"SIERRA 1500","year_from":2019,"year_to":2019,"match":"base","vehicle_ids":["2019_gmc_sierra"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
