Consumer Reviews for the Buick Encore GX
Read recent reviews for the Buick Encore GX
Great little SUV
Dean Whipple, 11/10/2020
2020 Buick Encore GX Select 4dr SUV AWD (1.3L 3cyl Turbo 9A)
I purchased my Encore GX to travel 62 miles each way back and forth to work. I needed a vehicle that got good gas mileage and had the option of AWD due to the snow the area receives in the winter. So far I have put over 6k on it and other then hitting a bear the SUV has been great. Even hitting the bear the Encore GX did its job. I was hesitant at first purchasing a 3 cylinder engine. It … has not been an issue. It has plenty of acceleration. I am avg. 29 mpg with the Encore GX. If you plan on traveling with 4 adults, the back seat is tight. However if you are looking for a great small SUV, take a serious look at the Buick Encore GX.
