There are 2 owner-reported powertrain & transmission complaints for the 2022 Buick Encorein NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
The EMC on the vehicle appears to be faulty. The vehicle is burning more than double the fuel than it should, and I’m able to smell a strong oil burning odor while driving it. The SUV lunges you forward violently when this defect begins to act up, which can be at any point in a short or longer trip. The vehicle has little to no power once this is triggered and seems to go into limping mode. I’ve had this to a dealer three times, and they have failed to repair the issue. The first time I left it there for almost a month and within three miles of the dealership, the same problem happened. The dealer denies that the repair should be covered under the emissions regulation, which makes GM-BUICK responsible for repairs of this equipment until 8 years or 80,000 miles.
I have had my vehicle to a GM dealer on a few occasions with the EMC code stored in the vehicle and an active check engine light on. While I’m driving - now during 70 percent or more of my trips - my vehicle loses power very suddenly and lunges me forward. I’m unable to stop and go on hills of any noticeable grade and have narrowly missed being in an accident many times. The dealer’s service manager has told me I should just BF glad the car is drivable when I have expressed ongoing safety concerns. I cannot get assistance from GM nor from the dealer in having this warranty connected part replaced. I do not have any other vehicle to drive, and I know I’m unsafe. I teach school and must get back and forth to work.
