2021 Buick Encore GX Common Problems by Component
50 owner complaints grouped by vehicle system.
ENGINE
11 complaintsOwners of the 2021 Buick Encore GX frequently report issues related to the turbo and engine stalling. Complaints often describe the vehicle going into "limp mode" with reduced engine power and a check engine light, commonly linked to turbo under-boost and coolant control valve problems. Some owners report sudden stalling without warning, which poses safety risks, especially in traffic. The failure mileage varies, with some incidents occurring as early as 9,000 miles. Additionally, there are reports of metal fragments from the turbo causing engine and transmission failures, with repair processes sometimes taking months and involving significant costs.
POWER TRAIN
10 complaintsOwners of the 2021 Buick Encore GX frequently report issues with the "Shift to Park" error message, which occurs when the vehicle is already in the park position, preventing the vehicle from shutting off or starting properly. This problem often requires multiple attempts to resolve and is reported at mileages ranging from approximately 17,500 to 61,000 miles. Transmission issues are also noted, with sudden transmission failure and diagnostic trouble codes indicating internal defects, especially around 66,828 miles. These failures can lead to loss of vehicle propulsion and control, posing safety risks. Buyers should be aware of these recurring issues when considering this model.
SERVICE BRAKES
7 complaintsOwners of the 2021 Buick Encore GX frequently report issues with the service brakes, with symptoms including a firm or hard-to-press brake pedal and unexpected, forceful braking. Some complaints describe a delay in braking response, while others mention the vehicle coming to an abrupt stop with minimal pedal pressure. These problems are noted at various mileages, from as low as 672 miles to over 81,000 miles. Safety implications include one report of a neck injury due to sudden braking, and concerns about potential crashes if failures occur at higher speeds. Buyers should be aware of these recurring brake issues and consider the potential need for repairs such as replacing the brake system control module or vacuum module.
UNKNOWN OR OTHER (6 complaints)
UNKNOWN OR OTHER
6 complaintsOwners of the 2021 Buick Encore GX frequently report issues with the vehicle incorrectly displaying a "SHIFT TO PARK" message even when the car is in park. This problem often prevents the vehicle from turning off and may require drivers to repeatedly attempt to engage park correctly. Complaints typically arise around 25,000 miles, with some owners mentioning repair costs not covered by warranty. Another issue involves post-service performance problems following fuel system repairs, where the vehicle hesitates or stalls. No safety incidents such as crashes or fires are reported, but the inconvenience and potential for battery drain are noted.
ENGINE AND ENGINE COOLING (4 complaints)
ENGINE AND ENGINE COOLING
4 complaintsOwners report recurring issues with the turbocharger in the 2021 Buick Encore GX, often leading to a loss of engine power. Symptoms frequently mentioned include the check engine light illuminating, a reduction in vehicle speed, and a failure to accelerate properly. These problems typically arise between 32,500 and 52,590 miles. Some complaints also describe loud noises related to the exhaust manifold detaching, although this is less common. The loss of power and reduced speed may pose safety implications, particularly if they occur at high speeds.
ELECTRICAL SYSTEM (2 complaints)
ELECTRICAL SYSTEM
2 complaintsOwners of the 2021 Buick Encore GX frequently report issues related to the vehicle's electrical system, particularly involving the Engine Control Module (ECM) and wiring. Typical symptoms include the illumination of the check engine light, a "warning reduced engine power" message, and significant power loss leading to sluggish driving and trembling at speeds over 35 mph. In some cases, wiring issues are attributed to tightly tied zip ties, as noted in a GM bulletin. Additionally, there are reports of complete power loss, affecting engine functionality and fuel/propulsion systems, which pose potential safety risks, especially at highway speeds. These issues often occur despite previous service attempts and can be exacerbated by branded titles, as noted by one owner who experienced reduced engine power leading to near-crash scenarios.
EQUIPMENT (2 complaints)
EQUIPMENT
2 complaintsOwners of the 2021 Buick Encore GX report issues related to a recall involving the vehicle's equipment, specifically concerning an emergency jack. Complaints frequently mention that parts necessary for the recall repair are unavailable, leading to delays in completing the repair. The typical symptom described is the removal of the emergency jack by dealers without providing a replacement, as parts are not distributed. These reports do not indicate any actual failures or safety incidents like crashes or loss of control. Buyers considering a used 2021 Buick Encore GX should be aware that this recall issue may still be unresolved due to parts availability.
VEHICLE SPEED CONTROL (1 complaints)
VEHICLE SPEED CONTROL
1 complaintDue to defective LIN BUS 2 failure to read mass air flow sensor, vehicle suddenly goes into limp mode. This speed control issue is documented in GM Technical Service Bulletins (TSBs) #22-NA-008 and PIP5934, 2022.
VISIBILITY/WIPER (1 complaints)
VISIBILITY/WIPER
1 complaintAbout 6 times in the last 3 months when I put the car into reverse and the reverse camera comes on the image is kind of sketchy and in weird colors - definitely not clear then it completely goes black with message at the top saying something about getting the rear camera repaired. It doesn't happen often but I can't use the rear camera when it does that so it's back to old school when in reverse looking everywhere and in mirrors before moving. It hasn't happened but once so far this month July 2025 but thought you should know.
FUEL/PROPULSION SYSTEM (1 complaints)
FUEL/PROPULSION SYSTEM
1 complaintTurbo charger has gone out 4 times since I purchased it in April 2021. I have been on the interstate driving and suddenly my car slows down and a message that says “engine power reduced” comes up and my check engine light comes on. This is dangerous as I was on the interstate with 18 wheelers and could’ve been rear ended and badly hurt or killed. My grandchildren could’ve been in the car with me. When this happens the vehicle slows down considerably and does not accelerate properly. I have to drive in the right lane at a much slower speed putting myself and others in danger. Leachman Buick in Bowling Green, KY has repaired the car twice. Campbell Chevrolet in the same city has repaired it twice and it is currently at this dealership due to the engine power situation occurring again. This has caused me severe inconvenience as I have had to drop my car at the dealership several times in the past few weeks and rearrange my schedule as a rental car has not been provided. Campbell Chevrolet repaired the vehicle a few weeks ago and the check engine light and reduce power message was back on within 6 hours of them initially completing the repair. Two weeks or less it was the waste gate actuator solenoid that was replaced but the engine message and check engine light are back on. I am VERY FRUSTRATED at having to jump through hoops regarding this vehicle. I own the Bluegrass Edition model and it is obvious that something serious is wrong with the car and Buick needs to recall the car IMMEDIATELY. It is either a lemon or something else is causing the turbo charger to repeatedly fail. I have taken the car to TWO different dealerships and neither one of them have been able to rectify the issue long term. The vehicle needs to have a TOTAL diagnostic test on EVERYTHING relating to the engine and power system. PLEASE LOOK INTO HAVING THIS VEHICLE RECALLED AS I DO NOT WANT TO LOSE MY LIFE ON THE INTERSTATE DUE TO REDUCED ENGINE POWER AND MY CAR AUTOMATICALLY SLOWING DOWN!!

How We Calculate Reliability Scores
Auto Reliability Index scores are calculated on a 0–100 scale using a weighted formula that combines multiple public data sources. Each factor is weighted based on its predictive value for real-world ownership experience.
Key Ranking Factors
Complaint Severity
NHTSA owner complaints weighted by component category (e.g., powertrain, safety systems, electronics, cosmetic) — safety-critical issues carry more weight than cosmetic ones. Adjusted for sales volume so high-volume models aren't unfairly penalized.
Repair Costs
Independent reliability ratings based on repair frequency, average repair costs, and severity of typical repairs for each model.
Recall Impact
Number of NHTSA recalls weighted by severity. “Stop driving” and fire-risk recalls are penalized more heavily than minor software or labeling recalls.
Issue Diversity
Measures how many major vehicle systems (engine, transmission, electrical, braking, etc.) have recorded complaints. A vehicle with issues spread across many systems may indicate systemic quality issues.
Scores are grouped into four tiers:
- 80–100: Excellent— Top-tier reliability, minimal issues
- 60–79: Good— Reliable with some minor concerns
- 40–59: Mixed— Notable issues, research before buying
- 0–39: Risky— Significant problems, proceed with caution
Data is sourced from NHTSA recall records, owner complaint filings, and independent repair databases. Scores are recalculated as new data becomes available. While the weighting model is proprietary, all underlying data sources are public and traceable.
