POWER TRAIN
When starting from a traffic light after the green light, the car made mechanical noises and would not accelerate above approximately 25 mph. It seemed obvious at the time that the transmission had failed, which was later confirmed after being towed to the dealership. There were no warning lamps or messages displayed; however, during the previous days, there were a few instances when the transmission "shifted" hard (this seemed odd considering it is a CVT transmission).

POWER TRAIN, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
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.

UNKNOWN OR OTHER
Component: Federal Safety Certification Label (49 CFR Part 567). Available for inspection. Summary: Vehicle was manufactured and sold brand new without the mandatory Federal Safety Certification Label. The omission was discovered during a professional trade-in inspection when the representative showed me where the label was supposed to be, but was missing from the car. The vehicle is currently non-compliant with federal safety standards, rendering it unmarketable. Confirmation: The manufacturing omission was confirmed by a review of historical authorized dealership service records. Photographs taken of the door jamb during routine service prove the label was never present. Symptoms/Warnings: There were no warning lamps or symptoms. I was never informed of this non-compliance by the manufacturer or authorized service centers during routine maintenance. Manufacturer Response: The manufacturer was contacted immediately via phone, email, customer service chat, and in-person to rectify the omission. However, the manufacturer failed to provide a resolution within the window of a time-sensitive trade-in valuation and tax credit package, causing the offer to expire. In subsequent communications, the manufacturer refused to remedy the non-compliance without charge, demanding payment for the label and labor in violation of 49 U.S.C. § 30120. The vehicle remains unmarketable and unused.

When trying to park/shut off, the vehicle gives ‘shift to park’ error message upon shifting to park and won’t shut off or when starting will give ‘shift to park’ error message and not start. This seems to be a common issue with this vehicle model…we could really use a recall

ENGINE, FUEL/PROPULSION SYSTEM
Trying to understand why a recall was not done on an engine issue on this car and instead GMC chose to send out 2 letters in 2024 detailing the problem that "might" happen with the engine losing power while driving and for owners to "carry" the letters in the glove compartment of the vehicle so the dealership could be aware of the issue. You were told to not bring the car to be serviced unless the issue was obvious. Well it happened when I was out of state and had to immediately find a GMC dealership to fix the issue for which my car was in a dealership in [XXX] for approximately one month. If the proper recall would have been made I would NOT have driven the car out of state prior to getting it fixed. I had family members in the car with me at the time and to lose power on an interstate was very scary to say the least. I feel that GMC failed it's customers with this vehicle and I will never buy another GMC vehicle or for that another vehicle US made vehicle. The issue was fixed at GMC's expense but they are now failing to reimburse proper funds for the rental I had to use putting a burden on my finances...be that as it may I am totally disappointed with the Buick Encore GX 2021. You try to support the "american made label" and this is where it got me for trying to do the right thing...I feel no one is looking out for the consumers on this particular issue b/c I'm pretty sure I'm not the only one it has happened to...A RECALL SHOULD HAVE BEEN DONE ON THIS ISSUE..!! This is 2021 with fewer than 48,000 miles and up to date services by reputable GMC dealerships since I have had the car. The case # with GMC for this issue is XXXINFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

SERVICE BRAKES
Brake System Control Module Replacement - The brake system control module needs replacement due to a fault detected with 10 volts on terminal 1. Replacing this component can help maintain proper functionality of the brake system and ensure consistent performance. Why would this all of a sudden be faulty after almost 5 years?

AIR BAGS, SEAT BELTS
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.

POWER TRAIN
The shifter assembly failed. When shifting to Park, a "Shift to Park" message appears on the driver information center. Although the shift lever is in the Park position, it is not recognized, and the car cannot be turned off or locked. The selling dealership inspected and confirmed the failure, which first appeared at about 21,000 miles (2023 model). The solution was to replace the shifter assembly (car is out of warranty by less than one month), at a cost of $562.10. Invoice breakdown: 1) Labor = 350.00, 2) Parts = 169.50, 3) Sales Tax = 42.60 It is interesting to note that the Labor rate of 350.00 is almost certainly a "flat rate", as the time to complete the repair was only about 30 minutes.
