Recalls on the 2020 Buick Encore GX

A complaint is one owner's allegation. A recall is the point at which the manufacturer or a regulator agreed the defect is real and dangerous enough to fix for free — however old the car is.

United States — NHTSA

21V440000

EQUIPMENT:MECHANICAL:ACCESSORY SCISSOR/SCREW/BOTTLE JACK/LIFT:STAND

General Motors, LLC. (GM) is recalling certain 2020-2022 Buick Encore GX and 2021-2022 Chevrolet Trailblazer vehicles. The emergency jack, if not positioned as directed in the vehicle owner's manual, can fracture while in use.

Risk: A fractured jack can cause the vehicle to collapse, increasing the risk of injury.

20V588000

SERVICE BRAKES

General Motors LLC (GM) is recalling certain 2020 Chevrolet Corvette and Cadillac CT4, CT5 and XT4, 2021 Chevrolet Trailblazer, and 2020-2021 Buick Encore GX vehicles. Sensor connection contamination in the electronic brake boost system may cause an interruption of communication between the sensor and the brake boost system.

Risk: If communication with the sensor is interrupted, the electronic brake boost assist could be lost. Extra pedal force will be required to slow and stop the vehicle, increasing the risk of a crash.

Canada — Transport Canada

Canada runs its own recall programme, and its campaigns do not always mirror the American ones.

Recall 2021365 14,781 units in Canada

Accessories

Issue: On certain vehicles, the emergency spare tire jack could break if it is not properly positioned under the vehicle. If this happens, the jack could collapse and the vehicle could fall suddenly. Safety Risk: A jack that collapses could trap or injure a person who is near or under the vehicle. Corrective Action: General Motors will contact owners by mail and instruct you to take your vehicle to a dealer to replace the emergency jack. The company recommends that you should not use the original emergency jack. Instead, if you are in a situation which requires its use, they recommend that you should call the GM Roadside Assistance Centre.

Recall 2020520 22,911 units in Canada

Powertrain

Issue: On certain vehicles, the start-stop accumulator in the transmission may be missing bolts. As a result, transmission fluid could leak and eventually cause the transmission to stop working. If this happens, there could be a loss of power to the wheels. Safety Risk: A transmission fluid leak onto a hot surface can create the risk of a fire. Additionally, a loss of power to the wheels could increase the risk of a crash. Corrective Actions: General Motors will notify owners by mail and instruct you to take your vehicle to a dealer to inspect the transmission start-stop accumulator. It will be replaced if any bolts are found missing.

Recall 2020452 404 units in Canada

Brakes

Issue: On certain vehicles, a sensor in the electronic brake boost system may have a bad connection. Under certain driving conditions, this could cause a loss of brake assist. If this happens, there would be a sudden increase in brake pedal force required to slow or stop the vehicle. Safety Risk: Reduced brake performance can cause extended stopping distances and increase the risk of a crash. Corrective Actions: General Motors will notify owners by mail and instruct you to take your vehicle to a dealer to replace the electronic brake boost module.

There was no service engine warning light on my dashboard. Pending codes in the pictures below popped up on my diagnostics tool less than 24 hours after buying the vehicle from an Audi Dealer. The engine went into limp mode as you can see from the picture below that shows Engine Power is Reduced. After researching these error codes, I was made aware that this is a common issue on this vehicle ad is should be a recall as it states the engine failure is a very serious issue, especially if it occurs while driving. This could cause fatal accidents.

POWER TRAIN

While reversing, the vehicle suddenly jumped/jerked unexpectedly. Another vehicle was parked close behind me, and I was afraid my vehicle was going to jump into it because the movement was sudden and difficult to control. On another occasion, while traveling approximately 20 mph through a longer curve, the vehicle suddenly jumped/jerked again and I was concerned I could lose control of the vehicle or strike another vehicle. The vehicle has also intermittently shuddered/jumped during normal driving and acceleration. At times the engine RPM increases without the vehicle accelerating normally. The problem is intermittent and may stop and then happen again. This makes the vehicle’s acceleration and movement unpredictable, which I believe creates a collision risk when reversing, entering traffic, traveling through curves, or accelerating around other vehicles. An authorized Buick/GM dealership inspected the vehicle and diagnosed the CVT transmission as needing replacement at a cost of approximately $4,700. The dealership told me there were no transmission diagnostic trouble codes and no transmission warning lights despite the symptoms and their diagnosis. I am concerned that this transmission condition can cause sudden jerking/jumping and unreliable acceleration without a warning light or diagnostic code alerting the driver. The transmission has not been replaced and the vehicle is available for inspection.

ELECTRICAL SYSTEM

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.

POWER TRAIN

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.

To Whom It May Concern, I am submitting a formal complaint regarding a recurring issue with my 2020 Buick Encore GX (VIN: [XXX] ) related to the “Shift to Park” defect, which is documented in GM’s Technical Service Bulletin 23-NA-119. My vehicle intermittently fails to recognize when it is in park, preventing me from turning off the engine and causing safety and usability concerns. Despite following GM’s recommended steps and scheduling an appointment through Buick Customer Care, I was charged $195 for a diagnostic fee and quoted $495 to replace the shifter assembly. The dealership confirmed the issue matched the bulletin, yet refused to offer goodwill coverage or reimbursement. This expense is a significant hardship. I am still making payments on this vehicle, which is barely five years old. I previously owned a Honda for 20 years without encountering issues like this. Unfortunately, this is not the first time I’ve faced a manufacturer-documented defect with no support. My previous vehicle, a Mitsubishi Outlander, suffered from a known transmission issue that was later part of a class action lawsuit. Despite experiencing the same symptoms, my VIN was excluded. The cost of repair outweighed the value of the vehicle, and I ultimately had to walk away from it as a total loss—leaving me without a car. I am deeply disappointed to now face a similar situation with Buick. I chose this vehicle expecting reliability and support, and I’ve done everything asked of me to address this issue responsibly. I believe GM should be held accountable for this known defect and the financial burden it places on consumers. Thank you for your attention to this matter.
