2025 Buick Encore Gx

I am reporting a defect involving my **2025 Buick Encore GX AWD manufactured by General Motors. Within two days of purchasing the vehicle, the dashboard displayed the warning message “Service Charging System – Vehicle May Stall.” I contacted the dealership on the third day of ownership and was instructed to bring the vehicle in for service. Since that time the vehicle has required multiple repair visits related to the charging system. Repairs included diagnosis of the electrical charging system, replacement of the alternator, and replacement of wiring harness components related to the charging system. I later learned the alternator had already been replaced prior to my purchase of the vehicle, and it required replacement again after purchase during the repair process. Because the charging system warning appeared almost immediately after purchase, I am concerned the defect may have existed prior to the vehicle being sold. Although the warning message is not currently appearing after the most recent repair, the defect occurred almost immediately after purchase and required repeated service visits. The vehicle still does not appear to operate normally. While driving at a steady highway speed, pressing the accelerator sometimes results in no immediate response. There can be a delay of approximately one to two seconds before the vehicle begins accelerating even when additional pressure is applied to the accelerator pedal. I have also noticed the engine sounds louder than expected while idling. Because the original warning indicated the vehicle may stall and the vehicle continues to demonstrate abnormal acceleration response, I believe this may represent a potential safety concern. I sought resolution with the manufacturer, however the manufacturer has not accepted responsibility for the condition. I am submitting this complaint so the issue is documented in case other owners experience similar charging system or acceleration problems.
