2025 Buick Encore GX Electrical System Problems

My 2025 Buick Encore GX has experienced an ongoing failure of the rear backup camera system. The issue began intermittently in February 2026, and earlier this month (March) it has progressively worsened. The camera now does not function at all. When shifting into reverse, the display often shows a black screen with a “camera unavailable” warning message. On some occasions, the camera briefly functions but displays severe distortion, including abnormal colors, flickering, and warning symbols overlaid on the image. The issue continues to occur intermittently and unpredictably. This failure creates a safety concern because the backup camera is a required safety feature intended to assist with rear visibility while reversing. The malfunction reduces visibility and increases the risk of not seeing objects, vehicles, or pedestrians behind the vehicle. The problem has not yet been inspected by the dealership due to limited appointment availability. I have documented the issue with photos and video showing the malfunction, including distortion and loss of image. Approximately 8 weeks after purchasing this vehicle in March 2025 (5/3/25) the Digital Instrument Cluster (driver information center) and infotainment display went completely black while driving, leaving no visible speed, fuel level, or other critical vehicle information visible to the driver. This raises concern about the reliability of the vehicle’s electronic systems, particularly as the backup camera— another critical safety feature— is now also malfunctioning. This issue has progressed from intermittent to consistent failure.

nStar remote diagnostic system returned five false-negative results across two confirmed mechanical failures. January 2, 2026: two diagnostics at 5:50 PM and 5:53 PM returned "No Error Code Found" while the transmission was actively failing. At 8:39 PM, the system identified P0700 and P2714 (Transmission System Failure, "Service within 1 day"). March 14, 2026: two diagnostics at 11:14 AM and 11:17 AM returned "No Error Code Found" while the vehicle could not exceed 20 mph on a highway. OnStar agent instructed a permanently disabled driver with a [XXX] passenger to continue driving during the first failure. GM issued a September 2025 TSB for "Loss of OnStar Connectivity" affecting all makes. FTC entered a 20-year consent order against GM/OnStar in January 2026. The Muhammad v. General Motors class action (E.D. Mich.) documents identical OnStar false negatives before engine seizures on the 6.2L platform. OnStar's diagnostic system appears unable to detect powertrain failures in sealed components across multiple engine platforms.

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.

In my car there is an electrical issue with the radio. Sometimes when I’m backing up and using the camera the lane assistance doesn’t work properly which can cause someone to back into things if they are using it. Also another issue it has is when I’m driving the entire radio and dashboard flicks and the screen goes out which is dangerous when driving because now I’m not sure what my speed level is checking gas levels if your on phone calls it isn’t consistent. I think this is a major safety issue not sure if it’s electrical but the dashboard and screen goes out together randomly and it affects reverse driving and just driving in general.

The contact owns a 2025 Buick Encore GX. The contact stated while driving on several occasions at undisclosed speeds and attempting to depress icons on the infotainment system, the screen froze. The vehicle was taken to a dealer on five occasions where it was diagnosed that the infotainment system needed to be reprogramed, and the radio needed to be replaced. The contact was also notified by the mechanic that the infotainment system screen needed to be replaced but the part was on back order. The vehicle was repaired but the failure persisted. The manufacturer was notified of the failure. The failure mileage was 100.
