We where lucky compared to the other lady who wrote in this problem area. We where parked in a parking lot, ran in store to get item, left car running for wife to listen to radio and stay warm. As I got in, we spoke and was ready to pull out of the parking space and the car went weird. The car hesitated a little but was still running and then all the warning lights came on. It told us on the screen that steering might be effected and engine will not run to full capacity. The car ran like it was in "limp" mode(like the Kawasaki ATV when they have issue). We made it home carefully and slowly. We called and dealership had the car picked up. It's been there over a week now, their computer hook up said it was the fuel pump and also a fuel line was needed, they are waiting for the parts to come in. We have leased the standard Encore's before this GX and we never had this issue with them other 4 cars. They have been a great car, we are in hope that this is not going to become a major issue for the GX series. We made it only 9K miles when this happened. We where thinking of buying it when the lease was up, not sure where our thoughts are now. If this is a bad batch of fuel pumps or such...It could harm someone like the other lady with this issue in the middle of a highway, I hope Buick if needed will inform others of this danger and involve a recall to keep and save lives, so far everyone's been lucky???
Purchased my 2022 Buick Encore GX from Alexander Buick, Oxnard CA. on July 14th, 2022. On August 4th, 2022 (3 weeks and 273 miles later) was driving in the fast lane of major freeway 101 in Southern Ca.. Without any warning the car died. How I made it across two lanes to my right to get off the freeway without a seconds notice to the many cars and semis behind me I was able to veer a dead car to the side of the road with no accidents and no loss of life (mine.) Car was towed to dealer and just informed this morning that it is a faulty high pressure fuel pump. Online I have seen that this is an issue with GM. I do not feel the dealer is in any way responsible as the car only had 6 miles on it when I drove it off the lot. Dealer called and will fix fuel pump. I am afraid to accept this car and will never feel safe in it but I do not know at this point my full rights or recourse.
