The contact owns a 2023 Buick Encore GX. The contact stated that while driving on several occasions at various speeds, the vehicle bounced to the left and the right, and the steering wheel pulled to the left or the right, making it difficult to steer the vehicle. The vehicle was not diagnosed or repaired; however, after a test drive, the dealer informed the contact that the vehicle operated as intended. The manufacturer was not notified of the failure. The failure mileage was approximately 13,978.

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).

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 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.

No accident just a concern. On my Buick the clasp for the front set belts are buried between the seat and center console. Making the fastening and unfasting very difficult. The further the seat is forward the more difficult it is. I guess my concern is this over sight may hamper the use of them or possibly cause entrapment during a stressful situation.

Malfunction of rear passenger doors and back trunk/hatch. My safety and the passengers of others is significantly at risk, the doors open slightly when turning, the seal of weather stripping opens and sounds of road noise is louder than if the door windows were open. Upon closing the drivers door and a passenger opening the rear driver side door the metal touched and made a loud metal impact sound. Paint has been removed from both doors in the exact same spot that this occurred. It seems as if the doors installed either have a faulty hinge, wrong doors attached on the rear passenger doors or their is a faulty design or weld. The rear door on the driver side is visibly unaligned to the drivers door and it appears the manufacturer added extra weather stripping to compensate for the incorrect door being installed. While the doors are locked and the vehicle turns or travels over bumps in the road it is very noticeable and I do not feel my passengers are safe. I’ve never had a vehicle s

AWD model with winter package in the desert doesn’t fair well.

Brakes squeaking, squealing and screeching. Replaced once at approximately 8k miles. Dealership ground down rotors twice, brakes replaced once. Tires are worn in the center. AWD GX, steering seems off and unstable. Brake pedal sounds and feels like a faulty spring inside. Pedal gets stuck when switching from gas to brake. Bounces back with spring feel and noise. At times it feels like I can’t control the brake when traveling at a low rated of speed and having to suddenly stop. Then while stopped on an incline the brake feels as if it releases while still depressing the brake jolting forward. Nearly forcing into intersection.
