When the subject vehicles were modified to extend the frame, the Anti-lock Brake System (ABS) module was not recalibrated to account for the different inputs from the vehicle resulting from the stretched frame. Therefore, when driving in a curve, the Electronic Stability Control (ESC) system, working together with the ABS, may react prematurely or be delayed in reacting, therefore increasing the risk of a crash. If the vehicle is equipped with the optional Advanced Driver Assistance System (ADAS), the ADAS camera was also not recalibrated to account for the different inputs from the vehicle resulting from the stretched frame. Therefore, when driving in a curve with the optional ADAS system activated, the Automatic Emergency Braking System (AEBS) and its accompanying warning light may be delayed in reacting and illuminating, also increasing the risk of a crash.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2023/MC-10232499-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2023/MC-10232499-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10232499","components":[{"id":"brakes","name":"Brakes","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"ISUZU","model":"N-SERIES","year_from":2023,"year_to":2023,"match":null,"vehicle_ids":[]},{"make":"ISUZU","model":"NRQ","year_from":2022,"year_to":2022,"match":null,"vehicle_ids":[]},{"make":"ISUZU","model":"NRR","year_from":2022,"year_to":2022,"match":"exact","vehicle_ids":["2022_isuzu_nrr"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
