Read recent reviews for the Buick Encore GX
Long term owner
Colorado Rural Dan, 08/05/2021
2021 Buick Encore GX Preferred 4dr SUV AWD (1.3L 3cyl Turbo 9A)
Know that this vehicle is better than the "professional" reviewers give it credit for. Incredible room up front. Very easy for this large Colorado, hat wearing cowboy, to get in and out of. My wife and I have no children at home so we are not concerned about back seat layout so I will not comment on that. Controls are intuitive, easy to use. Setting up my wife's apple and my android … phone was a snap. The car comes with it's own hotspot which is really nice in Colorado where we often had no cell reception while driving. Though we repeatedly saw that mileage on the highway would be at best 30mpg out real life experience, so far, is 36mpg. We live very rural and so do little to no "city" driving. Was not looking to buy a new SUV when we found this but could not refuse the deal Buick offered. Our good fortune. It is NOT underpowered. The EncoreGX gets the job done! If you are in the market for a new small SUV, look at the EncoreGX. Ours is in "preferred" trim 4wd, and truly cannot see why I would spend the extra to go up a model. This has everything that we could want. Update: I have now had this vehicle for 10 months. The 4wd has worked well for this winter. Handling has been excellent
I did replace the all seasons with snow tires. The hot spot was ok but did not work as well as I initially thought so did not pay for the subscription and let it lapse. The paint seems to chip easier than I think it should so I now have a bottle of touch up to use so that it does not become a problem. Would still rate this 4.5 stars. Would recommend and would buy again in the same situation. Update: Have now had for 1 year. Still love it. Now I see a reason for the upgrade and wish I had, as by now the extra money spent would seem inconsequential. I have the cloth seats, white. Would be much easier to keep clean if they were leather. I miss that it does not have the adaptive cruise control that keeps you spaced from the car ahead. I would still recommend to anyone wanting a small SUV. By the way, up here at 8,000 plus feet it gets over 40 mpg. I know it would not do that down at near sea level but is a nice thing anyway. 22000 miles now, year and a half in. Would still buy again, would recommend to a friend. Thought about upgrading to a 2023, however the Buick does not hold its value like my Subarus do so cancelled that idea. Update: Have now had for 38000 miles. No problems. As it has a turbo engine I change oil every 5000 miles to make sure the turbo charger is always running on clean oil. Has worked so far. If interest rates become reasonable again I will trade in for a new one. Would stick with the GX as I really like the way it handles in these mountain snows and I find it very comfortable to drive. Update: Still running strong. 34,000 miles plus. No major problems. Still like this vehicle a lot. Highly recommend. My model has the 6 year transmission with awd capability. Cannot speak to the 2wd models with the CVTs.
