I was driving on the interstate on June 7, 2023 heading to work doing the speed limit of 60 MPH and all of a sudden the check engine light came on and a message stated "Engine Power Reduced" and the engine literally dropped engine power immediately and thankfully there was nobody right behind me and I was able to get off the interstate to a safe place. I called the Buick GMC dealership where I purchased the vehicle and they said to bring it in. They pulled codes on it and it gave a code of "engine under boost" and they said they ran tests on it and could not find anything wrong after 3 days at the shop, they did a software update and told me to come and pick it up. Then not even a week later, I was driving and out of nowhere came the same engine light, message read "engine power reduced" and the engine lost power immediately and I called the Buick GMC dealership again and they said to bring it back in and it's there now. I called today to check in and they said they are going to test the Turbo on it and order parts, etc. but they still do not have a definitive answer as to what's wrong with it yet. I bought my 2020 Buick Encore GX new in November 2020 and it has about 26,000 miles on it. No recalls have been made on my VIN model - I am afraid to even drive this car again and get stuck somewhere away from help or at night - someone could have rear ended me when I lost power on the interstate doing 60 MPH and killed me!!!

We have two infants in car seats. The car does not have the car seat LATCH system in it. The instructions were followed in the cars manual for placement but none were found. There are indications on the seat where you should place the latch buckle but the latch welded hooks are not there. I took the vehicle to the dealership Buick Gee in Liberty Lake WA where it is leased and was also told there by the service manager and the sales team that there are no latch hooks to be found in this car for the car seat to attach to. They agreed that there should be some there and could be a mistake at the factory. The dealer manager also came out to verify the latch system was not in vehicle. He also went to look at the other vehicles of the same year make and model, all of which did not have the welded hooks in the car for the car seat latch system. When I worked at the fire department I thought this system was mandatory in all vehicles manufactured and sold in the USA after the 90’s. Thank you for looking into this production safety issue [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

I have only had the vehicle for a year. On multiple occasions the vehicle feels like it is slipping gears (more often when the autostop feature is turned on). On multiple occasions the vehicle has stalled out and would not do anything when pressing on gas- didn't even rev, did absolutely nothing. These stall outs happened crossing highways, at stop lights, stop signs, etc. There were no warnings prior to the incidences, though the vehicle did through an engine/transmission code afterwards, the code would go away. The first several attempts of taking it to the dealership (last year) as it is still under warranty- it was not checked. i was simply told it was a "glitch" and it was fine. They did not record in their system that i requested it to be checked either apparently. They only recorded that i brought it in for an oil change. They only checked into it this February after my boyfriend told them what it was doing. They kept it and replaced one part in the transmission. The vehicle continued to have the same issues and threw a code withing the first 5 minutes after picking it up. I took it back in- and they said it was doing the issues because of the code it threw. I told them it was doing it again before it threw the code. They said it simply needed a line vacuumed out, and then gave it back to me. It continued to have the same issues and stalled out again causing me to roll backwards onto the highway-into traffic. I took it back again. They kept it, and then told me they'd be replacing the entire transmission, but it is on backorder. Still no time frame when it will be repaired. They then told me i could have my car back and continue to drive it until the transmission comes in?!? I said no- it isn't safe, I just told you what happened and i could have been hurt or killed. I am not driving it, especially when i have my son to drive around as well! I have been without my car for at least a month now. I am paying for a car that i don't even have/can't drive.

While driving this 2020 Buick Encore GX with around 7,000 miles on the odometer, the entire electrical/electronic system shut down. Windows were inoperative, the AC stopped, the radio failed, the flashers did not work, etc. The only things that worked were the engine and brakes. I have no idea if the brake lights worked. I was able to drive the car to the dealership - Van Buick GMC in Scottsdale, Arizona where the car is now sitting and awaiting their inspection. In the 95 degree temperature here in AZ, I thought that I would die as I could not open the doors. I have since learned that I could have opened the doors by pulling the door handle twice. No one ever educated me on this. There were no advance warnings prior to the failure. This car is a death trap. Please NHTSA help me.
