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.

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.

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 s

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.

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

On the morning of 11/01/2025, the vehicle was in volved in a fire. The cause of the fire is uncertain so the insurance company is investigating it and asked I report it to the NHTSA.

I had just drove the car off the lot. On my way home there is this violent grip of the steering wheel pulling me into oncoming traffic. Then again to the right towards a telephone pole. During another casual drive, there was a loud clunk and another violent grip of the steering wheel to the left towards the double yellow line, my son was driving the car at the time. This has happened numerous times. I explained to the dealer that lane assist is suppose to keep you on the road not pull you off the road. There were no lights showing on the dash. Unfortunately this happens randomly so it did not happen when the car went in for service repair at Turner Buick. Turner Buick did not find the cause and did no repairs. If I leave lane assist turned off my car is fine however it is a brand new and i

Component: Parking Assist / Driver Assistance Sensors / Object Detection Incident Description: While operating my Buick Encore GX, I executed a controlled, low-speed right turn and struck a stationary structural column within the vehicle’s path. The column was a fixed, solid object located in close proximity to the vehicle—precisely within the range the vehicle’s parking assist and object detection systems are intended to detect. No audible or visual warning was provided at any time prior to impact. According to the owner’s handbook, these systems are designed to detect nearby obstacles and provide alerts during low-speed maneuvers, including turning and parking. The conditions of this incident fall directly within those operating parameters. The system’s failure to detect and warn of a

Second complete powertrain failure on March 14, 2026 at 13,993 miles, nine days after first repair (complete transmission replacement for bone-dry sealed transmission). Symptoms: sudden loss of power on highway (unable to exceed 20 mph with accelerator fully depressed), hollow sound, noise described as "like a rock tumbling around inside." OnStar diagnostics returned "No Error Code Found" twice (11:14 AM and 11:17 AM) during active failure. Dealer (Loveland Buick GMC) diagnosed "battery issue" but provided indefinite loaner with no return date. Symptoms are consistent with engine bearing or connecting rod failure matching Cook et al. v. General Motors (Case No. 1:26-cv-00229, D. Del., filed March 4, 2026) covering 1.2L/1.3L turbo engines in the Buick Encore platform. Complaint alleges GM k

Sealed transmission found "bone dry" at approximately 13,000 miles. No consumer-accessible dipstick. Complete transmission failure January 2, 2026. Second complete powertrain failure March 14, 2026, nine days after first repair completed. Symptoms on second failure (loss of power, hollow tumbling sound) consistent with engine bearing/connecting rod failure matching Cook et al. v. General Motors (Case No. 1:26-cv-00229, D. Del.) covering 1.2L/1.3L turbo engines. Dealer diagnosed "battery issue" on second failure and provided indefinite loaner. Vehicle purchased June 2025. Two failures within 9 months and 13,000 miles on a sealed powertrain system the consumer cannot inspect.

When I go 63 miles an hour the car starts chugging and my dealership changed the transmission fluid. I drove it home today and it still chugging. They called me and said they took a 2026 Buick encore and did the same thing but will not help me. They told me it’s a daily occurrence in the vehicle. It shouldn’t be chugging going up hills at 63 miles an hour.

The vehicle has a safety-related defect involving the safety restraint system. A warning message/light appears indicating a malfunction affecting occupant protection. This defect raises concerns regarding proper airbag and restraint operation in the event of a crash. I presented the vehicle for warranty service, but the manufacturer refused to diagnose or repair the safety defect solely because the vehicle was not currently registered. The vehicle is otherwise under warranty. No accident has occurred yet, but continued operation with this defect poses an unreasonable risk to the driver and passengers. The defect has been observed multiple times and remains unresolved. I am reporting this issue to NHTSA to prevent potential injury or death before an accident occurs.

The contact owns a 2025 Buick Encore GX. The contact stated that after refueling the vehicle, the gas pump nozzle was difficult to remove from the fuel filler neck when the vehicle was done refueling. The contact stated that there was one fueling station that he avoided due to the spring that was wrapped around the nozzle. The contact had taken the vehicle to a local dealer and was advised that the fuel inlet and port were functional and that there was no defect with the parts. The contact stated that the issue depended on the fueling nozzle. The manufacturer was not informed of the issue. The failure mileage was approximately 300.
