Recent 2021 Buick Encore GX complaints

Owner reports filed with NHTSA, as written (personal details removed). Complaints are not verified by NHTSA.

Forward Collision Avoidance · reported Nov 4, 2026
Many time while raining, the emergency brake goes off and the car breaks randomly. Also, while going around a curve/corner, if there is a car in the oppose lane coming towards me, my vehicle will detect it as being in front of me causing my vehicle to hit the breaks which has almost caused many many accidents. The lane assist pulls in every direction while it is raining also. All of these situations have happened many times on many different dates.
Power Train · reported Aug 30, 2026
Vehicle does not recognize it is in Park even when the shifter is placed in that position. As a result, the vehicle cannot be turned off. GM has issued a technical service bulletin for this issue, but has not yet performed a recall.
Forward Collision Avoidance · reported Aug 29, 2026

Extremely dangerous if you don't know that it's not functioning correctly. Also her adaptive cruise control doesn't work and I know for a fact it uses the same camera to work to be able to tell when a vehicle is ahead of you which her car does show the symbol for when a car is ahead of you but it…
