Example complaints
Engine: “The engine reduces power light came on almost two months ago I toke it to family gmc in St. George in sc. They put is on a machine and said they said the I think turbo compassion for the air to the gas is bad. I am still waiting on them to receive a part to fix it. So I was wondering if anybody else had this problem with the 2023 buick encore gx”
NHTSA complaint #11678725, filed 2025-08Other or unknown: “I was driving in heavy traffic when I got a reduced power message. There was no where for me to go to get out of the traffic. This is the second time I've had this issue. I have already replaced the entire turbo several months ago. I took it to the dealer then. They attempted to fix it with just replacing part of it. It didn't fix. The cost to fix it at the dealer was more than I could afford so I took it to a different shop. All together it cost around $2000. Now it's happening again!!”
NHTSA complaint #11755084, filed 2026-08Brakes: “I was driving and randomly my new 2023 Buick Encore GX and two error messages popped up and my brakes started being less responsive. The two error messages that popped up was Service ESC and Service Power Steering . I will be calling the service department tomorrow to get it checked to make sure nothing is wrong. This is apparently an issue with GM cars but I need to verify that it is not an ongoing issue.”

The vehicle has been in the shop multiple times since February 13, and the issue has not been resolved. A service advisor has stated he is not comfortable putting me back in the vehicle and wants to help get me out of this car. I am requesting escalation, a case number, and immediate resolution. After having the oil changed in February, the check engine light came on soon after. …”
