2021 Buick Encore Gx

The Frontview camera or its software is the issue. It allows the car to drift outside of the lane on both sides of the car before warning and or pulling you back over but then it just pulls you to the other line and lets you cross it back and forth if you let it and every time crossing the line. Extremely dangerous if you don't know that it's not functioning correctly. Also her adaptive cruise control doesn't work and I know for a fact it uses the same camera to work to be able to tell when a vehicle is ahead of you which her car does show the symbol for when a car is ahead of you but it doesn't slow down her cruise control leaving a gap between the 2 cars so again if you didn't pay attention you could smash right into the car ahead of you. I took it to one Buick dealer and they said there was nothing they could do but after research I learned it can easily be reprogrammed with the right obd2 computer and either driving it to recalibrate or doing a static calibration in a shop. I do know that there are service bulletins slightly related to this.

While driving check engine suddenly illuminated following by a "warning reduced engine power" message. Car began driving sluggish and driving over 35mph caused serious trembling. After multiple diagnosis with several engine codes pointing to issues with ECM, and mass air flow sensor, and the wiring affliated . I took the vehicle to the GMC dealership to get vehicle serviced and was told the wiring had broken and melted which caused the check engine to come on and the vehicle to drive the way it did. The cause was the zip tie being tied too tight as stated in GMs own bulletin number 22-NA-008. This should be a bulletin it should be a recall!

The contact owns a 2021 Buick Encore GX. The contact stated that while driving at an undisclosed speed, the brake pedal was firm while depressed, with several unknown warning lights illuminated. The vehicle was taken to an independent mechanic, and several unknown diagnostic trouble codes were retrieved. The vehicle was then taken to the dealer, but the vehicle was not yet diagnosed or repaired. The contact related the failure to NHTSA Campaign Number: 20V588000 (Service Brakes); however, the VIN was not included in the recall. The manufacturer was made aware of the failure and advised the contact to file a complaint with the NHTSA Hotline. The failure mileage was approximately 81,000.

A 2021 Buick Encore GX with 66,828 miles experienced sudden transmission failure while driving. The vehicle lost forward gear engagement and began slipping, creating an immediate safety risk to the driver and other motorists due to unexpected loss of vehicle propulsion and control. The vehicle was diagnosed by an authorized GM dealership. Diagnostic codes P2714 (Transmission Control Solenoid Valve 4 Stuck Off) and P0700 (Transmission Control Module Request) were confirmed. The transmission fluid was found to have a burnt odor indicating severe internal damage. The check engine light was the first warning symptom, followed by slipping and loss of forward gear. General Motors previously issued Technical Service Bulletin 24-NA-009 in March 2024 specifically identifying DTC P2714 on the 2021 Buick Encore GX as a known internal defect affecting model years 2020 through 2024. This bulletin confirms GM was aware of this defect prior to this vehicle's failure. Despite issuing this bulletin, GM has not issued a recall, leaving owners of affected vehicles responsible for repairs caused by a known manufacturer defect.

The 1.3L turbo caused metal fragments to get into my engine which in return caused the transmission to fail. My 2021 Buick encore gx has been in the shop since early February 2026 at Garber Buick in Fort Pierce Florida. The first diagnosis was solenoids needed to be replaced, after the solenoids were replaced they told me the engine needed to be replaced, once the engine was put in Garber Buick told me the transmission now needed to be replaced. GM motors have been involved I have case number and a case manager who has informed me that not only do they want me to pay 5,600 dollars after the first quote for the engine was 9,800 but they brought that price down to 5,600 they now since its the transmission want me to pay another 6,000 even though the car is only 2021 and the turbo caused all of this to happen. I have done some more research and GM has multiple lawsuits against them for turbo and transmission failures where GM told dealers to downplay issues.

Turbocharger is defective. Reduced engine power. Engine Power reduced shows up on my dashboard. I bought the car brand new at Lindsey Buick in Ohio. This car is too young for this problem. Lindsey Buick and GM need to stand up to accountability and transparency when it comes to delivering top quality products. My vehicle almost caused a horrific accident by not accelerating fast enough. I am [XXX] , a widow, and in need of my car being fixed.

My vehicle suddenly stalled and completely shut off while I was driving. No warning lamps, messages or other symptoms to alert me there was any engine issues. I was definitely put in danger as I was driving at rush hour in a 6 lane busy US 1 Federal Highway. The vehicle was stalled, without any power, in the middle lane with cars and trucks swerving around me at the last minute. I called 911 immediately and they dispatched cruisers to help push my vehicle across 4 lanes of traffic. This meant having to block 4 lanes of moving traffic. It was a long 10 minutes of waiting as angry drivers were leaning on their horns in frustration. AAA flatbed towed my vehicle to a near mechanic's shop, but it was after hours and had to be left there until morning. The mechanic inspected the problem and confirmed the issue was a fuel module and fuel pump failure. How does this happen without any alerts to the driver? How can you prepare a driver of such a serious engine failure putting that driver and other surrounding drivers at such a serious risk? This should be a safety recall and fixed by the dealer without charge to the driver. That is, if the driver is still alive.
