On some vehicles equipped with a start/stop engine control option, the system level interactions related to the transition of run/crank and accessory inputs to the engine control module (ECM) during a crank event are compromised. This results in communication issues between the ECM and the intelligent battery sensor. The check engine light will illuminate and the stop/start system is suspended while the fault is active, resulting in degraded fuel economy.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2016/MC-10126146-9999.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2016/MC-10126146-0001.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10126146","components":[{"id":"engine","name":"Engine","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"CADILLAC","model":"ATS","year_from":2016,"year_to":2016,"match":"exact","vehicle_ids":["2016_cadillac_ats"]},{"make":"CADILLAC","model":"CT6","year_from":2016,"year_to":2016,"match":"exact","vehicle_ids":["2016_cadillac_ct6"]},{"make":"CADILLAC","model":"CTS","year_from":2016,"year_to":2016,"match":"exact","vehicle_ids":["2016_cadillac_cts"]},{"make":"CHEVROLET","model":"MALIBU","year_from":2016,"year_to":2016,"match":"exact","vehicle_ids":["2016_chevrolet_malibu"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
