As a result, a second repair is required.\n\nOver time, the transmission control valve could wear and lose pressure. If this happens, the transmission could shift harshly and could cause the rear wheels to lock up.\nNote: This recall only affects vehicles equipped with a diesel engine.\n\nSafety Risk:\nRear wheels that lock suddenly could cause a loss of control and increase the risk of a crash.\n\nCorrective Actions:\nGeneral Motors will notify owners by mail and advise you to take your vehicle to a dealership to update the transmission control module software to detect excess wear in advance of a wheel lock up. If detected, a service engine light would turn on, a message would display in the instrument panel and the vehicle would be limited to fifth gear.","consequence":null,"remedy":null,"notes":null,"mfr_campaign":"N252516560","part_number":null,"units":46,"completion":null,"do_not_drive":null,"park_outside":null,"notification":"Safety Mfr","french":{"component":"Groupe motopropulseur","notification":"Sécurité - fabricant","summary":"Problème :\nSur certains véhicules, la réparation effectuée par un concessionnaire General Motors dans le cadre du rappel N242454440 (rappel numéro 2024-637 de Transports Canada), pourrait ne pas avoir été effectuée correctement. Par conséquent, une deuxième réparation est nécessaire.\n\nAu fil du temps, la soupape de commande de  la boîte de vitesses pourrait s'user et perdre de la pression. Si cela se produisait, la boîte de vitesses pourrait changer de rapport brusquement et entraîner un blocage des roues arrière.\nRemarque: Ce rappel ne concerne que les véhicules équipés d'un moteur diesel.\n\nRisques pour la sécurité :\nDes roues arrière qui se bloquent soudainement pourraient entraîner une perte de contrôle et augmenter les risques d'accident.\n\nMesures correctives :\nGeneral Motors doit aviser les propriétaires par la poste et leur demander d'amener leur véhicule chez un concessionnaire pour faire mettre à jour le logiciel du module de commande de transmission, afin que toute usure excessive soit détectée avant un blocage des roues. Lorsqu'une usure excessive est détectée, un voyant « Service Engine » s'allume, un message s'affiche dans le tableau de bord et l'embrayage du véhicule est restreint au cinquième rapport."},"vehicles":[{"year":2020,"make":"CHEVROLET","model":"SILVERADO","vehicle_id":"2020_chevrolet_silverado","match":"exact","built_from":null,"built_to":null},{"year":2021,"make":"CHEVROLET","model":"SILVERADO","vehicle_id":"2021_chevrolet_silverado","match":"exact","built_from":null,"built_to":null},{"year":2022,"make":"CHEVROLET","model":"SILVERADO","vehicle_id":"2022_chevrolet_silverado","match":"exact","built_from":null,"built_to":null},{"year":2020,"make":"CHEVROLET","model":"SILVERADO HD","vehicle_id":"2020_chevrolet_silverado","match":"base","built_from":null,"built_to":null},{"year":2020,"make":"GMC","model":"SIERRA","vehicle_id":"2020_gmc_sierra","match":"exact","built_from":null,"built_to":null},{"year":2021,"make":"GMC","model":"SIERRA","vehicle_id":"2021_gmc_sierra","match":"exact","built_from":null,"built_to":null},{"year":2020,"make":"GMC","model":"SIERRA HD","vehicle_id":"2020_gmc_sierra","match":"base","built_from":null,"built_to":null}],"may_apply":true,"as_of":"2026-10-19","lookup":{"nhtsa":"https://www.nhtsa.gov/recalls","tc":"https://wwwapps.tc.gc.ca/Saf-Sec-Sur/7/VRDB-BDRV/search-recherche/menu.aspx?lang=eng","maker":null},"attribution":["Contains information licensed under the Open Government Licence – Canada."],"url":"https://open.wenmarpro.com/recalls/tc/2026060"}
