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 clearly present obstacle constitutes a safety defect. Safety Risk: The driver assistance system failed to perform as represented, creating a heightened risk of collisions with stationary objects in low-speed maneuvers. Drivers relying on these systems cannot reasonably expect alerts to avoid collisions in confined spaces such as parking structures or tight turns.

While driving for approximately 2 1/2 hours with cruise set at 78. I did need to brake on occasion and then resume speed. For no apparent reason the car suddenly braked. Speed dropped to about 50 and then immediately resumed speed. No one was hurt. Things in the back seat pushed forward. I don’t know if it has anything to do with that incident but from them until I returned home, about 1 hour later my windows were fogging, I turned on the defrost about 3 times.

Component/System Failed: Tire Sidewall (Continental CrossContact LX20 EcoPlus+, Size: 255/55R20 107H). I am reporting a potential safety defect regarding my Continental tires. While my specific mold number (S-421232) is not currently listed in NHTSA Campaign 20T018000, the tires were manufactured in the same week (DOT 0420) and show symptoms consistent with the overcuring defect described in that recall. I have observed unusual marks and [mention what you see: e.g., "cracking," "distortions," or "bubbling"] on the sidewall. These marks appeared without any impact or road hazard. Given that this specific model and production week are already associated with sudden sidewall breakage and carcass failure, I am concerned that the existing recall scope is too narrow and that my tires pose a similar risk of sudden air loss or crash.

The contact owns a 2017 Buick Encore. The contact stated that while driving at an undisclosed speed, the vehicle experienced a sudden loss of power and went into "LIMP Mode". Additionally, there was smoke coming from the rear of the vehicle. The dealer was notified of the issue but declined to service the vehicle because the vehicle had a salvage title. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 88,000.

Odometer Fraud. The contact purchased a 2017 Buick Enclave. The contact stated that the check engine warning light was illuminated. The contact attempted to have the vehicle serviced at the dealer, but services were declined. It was discovered that there was a mileage discrepancy. The vehicle was a dealer sale. At the time of purchase, the vehicle mileage was 92,000, and at the time of obtaining a Carfax report, it was discovered that the mileage was 95,015. The vehicle was taken to an independent mechanic for service, but was not repaired. The State Attorney General was contacted, but no additional assistance was provided.

Description of Safety Defect: While operating the vehicle at approximately 25-30MPH and make a right turn, the vehicle experienced a sudden and total loss of power/engine stall, accompanied by a "Check Engine" light and a "Reduced Engine Power" notification. This resulted in a near-collision on a public roadway. The vehicle's steering and braking response were significantly compromised during this event, creating an immediate life-safety hazard for the driver and passengers. Dealer/Manufacturer Response: The vehicle was recently in the possession of McGovern Buick GMC Westborough for service. Despite the vehicle exhibiting an active Check Engine Light (CEL), the dealership staff pressured the consumer to take delivery of the vehicle and drive it on public roads. The service advisor admitted in writing that the CEL was active but insisted the vehicle was "feel free to drive." Furthermore, the dealership attempted to falsify internal corporate safety notes to claim the consumer "insisted" on taking the vehicle, masking a known mechanical defect. This represents a willful suppression of a safety defect by a franchised dealer, which led directly to a hazardous operating condition. Injuries/Crashes: No crash occurred, but a near-miss was documented. Passenger experienced severe emotional distress due to the sudden loss of vehicle control in traffic.

I am reporting a serious safety issue with my 2023 Buick Encore GX that repeatedly shuts off while driving and doesn’t restart when auto stop is on, it leaves me stranded in traffic. The vehicle has been in the shop multiple times since February 13, and the issue has not been resolved. A service advisor has stated he is not comfortable putting me back in the vehicle and wants to help get me out of this car. I am requesting escalation, a case number, and immediate resolution. After having the oil changed in February, the check engine light came on soon after. Car had left me stranded prior to the battery being replaced. After 4 times in the same shop, they say a bad ground connection may now be the problem, however they also said they recharged the battery the visit prior.
