6. Filed May 4, 2026Failure Apr 28, 2026177,000 milesHinckley, OHElectrical system, Body control module/bcm

   The contact owns a 2015 GMC Acadia. The contact stated that while driving at 25 MPH, the instrument panel went blank before the panel began to flash when it returned. The contact then stated that several various warning messages began to appear all of which were related to the vehicle's electrical features. The vehicle was then taken to an independent mechanic where a code reader found no defects with the vehicle. Close to a week after the initial failure, the vehicle failed to start after multiple attempts as previous failure returned. Due to the failure, the vehicle was towed to an independent mechanic where it had yet to be serviced or diagnosed. Upon his own inspection and research regarding the vehicle, the contact linked the failure to the vehicle's BCM(Body Control Module). The dealer nor the manufacturer had yet to be notified of the failure. The failure mileage was approximately 177,000.

7. Filed Apr 22, 2026Failure Feb 12, 2026Aurora, ILBlind spot detection

   Issue: Repeated failure of safety‑critical module Description: The Side Blind Zone Alert system on my 2015 GMC Acadia has failed multiple times over the life of the vehicle. The system becomes inoperative and displays “Side Detection System Unavailable.” A local GMC dealer has diagnosed the issue as a failure of the SBZA module due to loss of communication. This failure has occurred repeatedly, approximately every two years, despite prior repairs and replacement of the module at my own expense. This is a safety‑critical driver‑assist feature, and the repeated failure pattern suggests a defect in the design or durability of the module. The system is unreliable and cannot be depended on for safe lane‑change operation. GM Customer Assistance has declined to provide support or escalate the case further, despite the safety implications and documented repeat failures. I am reporting this because the failure affects safe operation of the vehicle and appears to be a recurring defect affecting multiple owners of this model.

    The engine is not shifting properly, and the vehicle loses speed while driving and hesitates to accelerate. At time, it feels as though the car is not moving at all. This issue has occurred on multiple occasions, affecting both me and my family, and has forced us to pull over because the vehicle could barely move forward. This happed once on the highway and almost caused an accident. Additionally, the check engine light remains on at all times.
