2022 Buick Encore Owner Complaints

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.

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.

My Encore is full of mice and mice droppings. The man at the dealership said GM should have screens or other safety measures done at the factory. This car has just 10,000 mils and I keep it in pristine condition. People can't believe how clean I keep it and this happens??? The tech told me there are at least 8-10 spots were mice come in. It is too easy for them. My brand new car is going to be totaled or close to it. I have AAA, but am already with all the added fee's at Enterprise car rental and my $500 deductible $700 out of pocket! I'm [XXX] and on a very fixed income. I'm still making car payments for the next 4 or 5 years. It's like never smoking and getting lung cancer. I didn't do anything wrong. GM is responsible. The are very irresponsibly in their manufacturing. Should I get a lawyer? The man who's meeting with the adjuster from my insurance told me how dangerous it was for driving this car. He said the smell (which I was unfortunately used to it, it's called olfactory fatigue, also known as odor fatigue, olfactory adaptation,) was very toxic. Yes, Gene Hackman's wife died from the inhaling rodent waste. I'm a Respiratory Therapist and know about the toxic particular you don't see and how it can and will kill you. Something has to be done. There are millions of innocent people that are dying because GM is too cheap to have this done in the factory! Please help asap. Thank you.

While driving on interstate highway, CEL illuminated. When able to stop and check, DTC codes P1467 & P146b where detected. These codes deal with the Evap Purge system. The pump was recalled in model year 2021 for the make, model and engine in this vehicle. Failure to fix this issue results in increased fuel vapor escaping to the atmosphere as well as potential system damage. Since the same part was faulty in the previous model year, it seems GM did not correct the issue. A recall should be issued or an extended warranty with reimbursement in the 2022 model year also. Thank you.

Seatbelts on my year old Encore with only 15k are frayed and unraveling, I am having the vehicle in for other unrelated repairs on Friday and will be certain to inform the dealership at that time but feel that this is extremely dangerous and totally unacceptable in a year old vehicle and I feel like I or my passengers could be injured or thrown from the vehicle in the event of an accident, no warning lamps or messages prior to failure.
