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.

Car has less than 30 (thirty) miles on it; garaged since purchase bc of pandemic; started occasionally; battery dead when I tried to go out last week; charged battery; died again; charged again; check engine light alerted onstar, who sent email stating problems w/engine & transmission system, possible issues w/fuel management system, emissions control, misfire condition... only 30 miles! new car! just drove home from dealership and parked it. Tried chatting w/Buick customer experience, but they cut me off 3 times over 2 hours, so I gave up that exercise in futility. Dealership is unpleasant; trying a different dealer. Googled recalls. This sounds like the emissions system recall on the 2021 Encore gx, but mine is a 2020. Why would a brand new, $38,000-car be so frighteningly unreliable? I traded in two cars and saved many years to buy this. I'm afraid to even drive it in for service. My dad was a patented engineer. I miss my dad.

Started having trouble last week with the fuel gauge and a check engine light. Took the car in to have it serviced and they found that rodents had chewed through the harness located by the fuel. Cost $850 to repair which was not covered under warranty. Had the car back two days and went to use the car and it completely stopped functioning once we pulled out into traffic. We live on a highly tractor trailer traveled road and having the car just stop working could have ended in an accident if a car was coming from either direction. My son was in the passenger seat and I am incredibly upset that they could have been hurt. We needed to call the police and a tow truck with my youngest son in the car. Received a call from the dealership after inspection to find of the same harness has been chewed through again. The harness apparently is a soy based product. We are being told once again this is not covered under warranty and my bigger concern is how this is going to stop happening. This does not sound like an outside influence but rather a manufacturing defect. Using a soy based product maybe cheaper to manufacture and better for the environment but it's going to make the car completely unsafe for my family to be in. If the harness is going to be made out of a soy based product and I believe that this should be something now covered under warranty and not expected for us to pay out of pocket for.
