1 Electrical System problem of the 2016 Buick Encore

Failure Date: 01/04/2026

I was stopped at a traffic light and began moving forward to make a turn into traffic. As I activated my turn signal and started to proceed through the intersection, the vehicle suddenly stalled and shut off without warning, causing an immediate loss of power while the vehicle was in motion. Another vehicle was entering the intersection at the same time, creating a near-collision situation. I was forced to restart the vehicle in traffic. The incident occurred within less than 250 miles of purchasing the vehicle. The vehicle had recently received an oil change and inspection. No warning lights or messages were observed prior to the stall. This event created a serious safety risk.

5 Electrical System problem of the 2018 Buick Encore

Failure Date: 06/04/2025

The car experienced issues with the fan turning off when car was turned off. It caused the battery to die. The car was serviced at the dealership and the tech found that the fuse block overheated and melted, causing poor electrical connections. They replaced the damaged parts and repaired the wiring. This still did not explain the fan not turning off and after the fuse block repair, the cooling fan was still sticking on. After pushing the dealership to further look into the issue the mechanic determined the issue was inside the fan assembly (it was assembled in the wrong direction), so they replaced the cooling fan. The dealership stated that this was a manufacturing error. They said this could have caused an engine fire and there was absolutely no warnings - just a fan that was stuck on. This could have put me and my new baby at risk for an engine fire and could cause issue for other owners if there were more assembly errors. The car is available for inspection if needed. It was only inspected by technicians at the dealership.

6 Electrical System problem of the 2019 Buick Encore

Failure Date: 04/08/2025

I have been calling autonations for months now since my car started driving funny. I was first told it was a head gasket that needed replacement however using my VIN number the engine that’s currently inside the vehicle is not the one that matches with what pulls up using the VIN number. Than the antifreeze leaks out, the oil leaks out and one day the car started smoking on the freeway with my children and I inside. It just stopped and haven’t been working ever since. I literally just got messed out of money because I purchased this vehicle a year ago not knowing it was a recall and this is one of the recalls now I am completely screwed over without a car and my money!! now I’m being told I have to pay because this car was sold to me already over the mileage limit to be fixed for free!!.

8 Electrical System problem of the 2014 Buick Encore

Failure Date: 04/30/2024

My 2014 Buick Encore at random times when I turn the key to start the vehicle it just clicks once then complete power out even though the battery is fully charged. To deal with the issue I need to open the hood, unplug the negative from the battery and reconnect it. Then try again. I do this at least once every week, sometimes multiple times throughout a single day. It also does it when a new battery is used. Ive also has a mechanic inspect the vehicle and was so frustrated that everything seems okay but just couldnt figure out why the vehicle don't start. 12 hours of searching for the source of the problem , after giving up on the vehicle I turn the key and it turned on. Other time the vehicle will turn off when already driving. I need this problem fixed. I honestly regret financing this vehicle in January 2024. I was dealing with this problem since may 2024. 73000miles when I bought the vehicle and now at 84000mile. Half of the year 2024 it's been repeat problems with this vehicle. This vehicle should have been a lemon.

10 Electrical System problem of the 2020 Buick Encore

Failure Date: 04/05/2024

Imthe original owner and purchased the car new 4 years ago. At 89,000 miles, the check engine light came on indicating codes for emission controls not working efficiently. Later additional codes indicated problems with the fuel evaporator. The car started having problems every time I filled up the gas tank it would stall, hesitate and have problems starting shortly after the fill up. Problem also occurred if I let the fuel level run down to 1 gallon when the reserve indicator light came on the fuel tank. So now I fill up when I reach a quarter tank. Steady driving for at least 10 minutes would clear the problem temporarily. Car hesitates, stalls and misfires when going uphill, steep hills and also when coming to full stop such as a red light. Later additional problem of car hesitating and misfiring during acceleration. I have replaced the spark plugs and ignition coil. No change noticed. Awaiting mechanic diagnosis. This problem seems very similar to another complaint filed under NHTSA id 11548946 in October 2023.

26 Electrical System problem of the 2017 Buick Encore

Failure Date: 05/06/2022

Vehicle has been in and out of shop since Feb 2022 for 'limp mode' disabled due to faulty booster or something. Vehicles leave driver stranded unable to accelerate or maneuver vehicle to avoid a collision. I'm told this is a well known problem for both this vehicle and the chevy cruze although no recalls are out for this huge safety issue. Somebody is seriously going to get injured if driver is unable to move car to safety when it just dies on the highway or road. All documentation is available for the excessive repairs that don't resolve the issue the correction only last from 24 hours to 2 weeks before the light comes on again and car dies.

28 Electrical System problem of the 2015 Buick Encore

Failure Date: 04/04/2022

We have had problems with the air bags since the car was new. The srs light would come on for a couple months then go off. It says it has a problem with the passenger presence module. Never had a recall but the dealer said that when we took it in for an oil change they updated the firmware on the air bag system. It never did work, it would sometimes work then not work. I took it back a few weeks ago and told them it still isn't right and I said since it is a safety issue they should cover it. They told me that since ohio doesn't have auto inspections that they are not responsibile for taking care of it and I was looking at over 1000 to repair. That pissed me off so I took my car and left. I am taking it to a independent garage. I have had lots of problems eith this car and only have 42000 on it now. My last gm, next will be Toyota/.

Traction light keeps coming on. 3. Power steering goes out 4. Press on gas and have to floor it in order to just crawl to a place to stop. 5 hard jumps after stopping at a light have had this in to tasca Buick and each time they say they fixed it - then it happens less then 2 weeks later. Have told them this car is going to kill someone with the steering going out while driving. I have a 2015 beautiful Buick Encore in the drive that I cannot drive.

1. What component or system failed or malfunctioned, and is it available for inspection upon request? the windshield wipers stop and or turn on intermittently. They have stopped in the middle of a rainstorm on more than one occasion and they have turned on while just driving normally without any of the controls being touched. 2. How was your safety or the safety of others put at risk? my safety is put at risk anytime I am driving my vehicle in the rain (it rains heavily and a lot where I live). My visibility has been suddenly reduced to zero during highway travel requiring me to put on my hazard lights and attempt to pull off to the side of the road if I dare to try crossing lanes without being able to see. 3. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? on Friday 24 Sep 2021 the car will be inspected by a certified Buick mechanic. 4. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? there are no warning lights or any other symptoms present, however, the audio on the right side of the car has stopped working but I am not sure if they issues are related.

34 Electrical System problem of the 2018 Buick Encore

Failure Date: 08/02/2021

Twice I was driving my car going about 35-45 mikes an hour. My car started to shake along with a loud humming sound. I lost my power steering and brakes. The over drive light was flashing both on the right under radio and on the dash. The rpms started racing as well one time for sure. I was able to get to the side of the road and hit the emergency brake at the same time put it into park. I was so scared. I waited a few minutes turned it back on and drove around a parking lot before I ventured home. The second time I was close to home and drove it home 10 miles an hour. Since then I am extremely scared to drive my car. Being a nurse I need my car. I took it to sterling Buick in venice. They ran a diagnostic test and it showed nothing. They drove it and of course it did not do it. There suggestion was for me to trade it in. They charged me and sent me on my way. They fixed something with my ac. When I droved the car days later my fiance called to tell me that there was something now leaking from the bottom of my car and took pictures of the brown pink color fluid dripping from undermeath the car. I called Buick. They suggested they would give me on star for 6 months!!! really!!! I they want to beable to find me in a ditch. I can not in good concious trade that car in knowing what has happened. If someone does not have the hinsight to beable to stop it they can be killled or kill someone else! the first time it happened I had my kids in the car and they were screaming. The second time I had 2 friends with me.
