2020 BUICK ENCORE Complaints

The cluster display shows "shift to park" even while vehicle is stopped, gear shift in park position, and engine is off.

I am submitting this complaint regarding several serious mechanical and electrical issues with my 2020 Buick Encore GX that raise significant concerns about the vehicle's reliability and safety. Most concerning, I was recently informed by the dealership that my vehicle requires another transmission replacement, despite having the transmission replaced in 2024. I was also advised that I would need to pay for an additional diagnostic inspection because technicians discovered oil leaking through the lines, which appears to have contaminated engine components. According to the dealership, metal particles have been found within the engine, causing it to malfunction. They have stated that they are unable to determine the source of the contamination at this time. In addition to these major mechanical concerns, I am experiencing several electrical and system malfunctions, including: The passive keyless entry system does not consistently unlock the doors using the exterior door handle, even with a brand-new battery installed in the key fob. The vehicle repeatedly displays a "Shift to Park" warning even though the gear selector is already in the Park position. The vehicle continues to display brake-related alerts and notifications indicating that the brakes need to be serviced or replaced, despite having brand-new brakes installed. These ongoing issues have resulted in repeated repair costs, loss of confidence in the vehicle, and concerns about my safety while driving. The transmission failure occurring shortly after a previous replacement, combined with unexplained engine contamination and persistent electronic malfunctions, suggests there may be underlying defects that warrant further investigation. I respectfully request that these issues be thoroughly investigated to determine whether they are related to known manufacturing defects or warrant a safety recall or other corrective action. I also request that Buick review my repair history and provide appropriate assistance.

Transmission would not connect with the engine. La Fontaine dealership in Saint Clair. Said I need a new transmission cost $14,000. It has 59823 miles under the vehicle.

I took my 2020 Buick Encore to an independent auto repair shop to have a brake inspection after I had contacted GM multiple times about the loss of acceleration, check engine light and stabilitrak light would come on with brake pedal stiffness and then almost needing to push it to the floor to stop. When I took it to the independent auto repair shop for the brake inspection they informed me of a PO161 code recall so I contacted my local recall service center, only to get a phone call from one of their salesman to come in and see about getting a new car. I've had other issues with this car since buying it in September of 2022 but now it's a serious safety situation and all they can either say is it doesn't match my vin so I'll have to pay out of pocket or go in debt for a new one. I don't know what to do at this point I feel at a loss.

My 2020 Buick Encore GX which has only $30,600 had the "Shift to Park" message appear on the dashboard screen and my car was not turning off properly. I read online that it is a widespread known issue: however, I had to pay $630.14 to fix the GM well know widespread issue so I can turn off my vehicle. This should be covered FREE of charge by GM as they are aware of the issue affecting the 2020 Buick Encore GX.

I am writing to formally report a serious mechanical failure involving my vehicle and to request further review and assistance. While operating my vehicle, it unexpectedly stalled in the middle of an intersection, creating a significant safety hazard. At the time of the incident, the check engine light illuminated and the RPMs surged to a range between 6 and 8. I was able to safely move the vehicle to the side of the road, place it in park, and have it towed to a dealership for inspection. Following their evaluation, I was informed that the transmission requires replacement. I have since become aware of a recall related to transmission issues; however, I was advised by a Buick representative that my VIN is not included in the recall. Given that my vehicle is experiencing the same or a substantially similar failure, this determination raises concerns and warrants further review. I have consistently adhered to all recommended maintenance schedules and have taken proper care of my vehicle. Based on the circumstances, I respectfully request a thorough reassessment of my case, including reconsideration for coverage or assistance with the necessary repairs. I appreciate your prompt attention to this matter and look forward to your response.

Defective "TURBO CHARGER" at 38,091 miles. The defective worn-out or damaged turbocharger was removed from the engine and a new one was installed at a cost of $1816.00. This part should not wear out at 38,000 miles. My mechanic informed me that this is common in the Buick Encore vehicles to experience a defective "TURBO CHARGER" at low vehicle mileage.

My 2020 Buick Encore GX is showing a message with accompanying ding ding sounds "Shift to Park" after I put my car in park. This malfunction will not allow the car to be locked. I see there are many complaints and lawsuits that GM has not attended to. How do we get GM to initiate a recall on something they are and were well aware of.
