I took my 2020 Buick Encore to an independent auto repair shop to have a brake inspection after I had contacted GM multiple times about the loss of acceleration, check engine light and stabilitrak light would come on with brake pedal stiffness and then almost needing to push it to the floor to stop. When I took it to the independent auto repair shop for the brake inspection they informed me of a PO161 code recall so I contacted my local recall service center, only to get a phone call from one of their salesman to come in and see about getting a new car. I've had other issues with this car since buying it in September of 2022 but now it's a serious safety situation and all they can either say is it doesn't match my vin so I'll have to pay out of pocket or go in debt for a new one. I don't know what to do at this point I feel at a loss.

Defective "TURBO CHARGER" at 38,091 miles. The defective worn-out or damaged turbocharger was removed from the engine and a new one was installed at a cost of $1816.00. This part should not wear out at 38,000 miles. My mechanic informed me that this is common in the Buick Encore vehicles to experience a defective "TURBO CHARGER" at low vehicle mileage.

I've been dealing with a frustrating car issue lately where my vehicle keeps stalling and hesitating during acceleration - whether I'm pulling away from a stop or trying to pick up speed on the road. After getting it checked out, my mechanic determined that the high pressure fuel pump control module is the culprit and needs replacement. The problem is, we're stuck waiting for the part because Buick has it on backorder indefinitely. What's particularly concerning is that GM recently issued a recall for this exact same fuel pump issue on certain models, but somehow my VIN number didn't make the cut. I strongly believe it should have been included, especially considering the safety implications here. When this fuel pump control module fails, it can completely cut off fuel flow to the engine, which creates a serious traffic safety hazard. Nobody wants their car suddenly losing power while merging onto a highway or navigating through an intersection. This isn't just an inconvenience - it's a legitimate safety concern that affects real people on real roads every day.

I am co-owner of the vehicle. My daughter was driving the SUV when the Check engine light came on. There was no warning whatsoever, and the turbocharger has gone bad . Prior to the light eliminating there was nothing wrong with the suv. I was driving the suv when the check engine light came on. I also own another 2020 Buick encore where this also happened. I was driving the vehicle when the check engine light came on with no prior warning and it was a failed turbocharger. There is something wrong with these vehicles .

Unknown issues w/ sensors and wiring lead to turbocharger failure. This led to spontaneous acceleration issues on the highway. Less than a year after the warranty covered the replacement of the turbocharger (less than 60k miles on the car) the turbocharger again failed (64k miles on car).

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

I currently own a 2020 Buick Encore since new with only 18,389 miles on it. Recently, I noticed on the Buick Encore that it lacked stopping power. Upon checking the air in the tires for winter I noticed that the rear brake rotors were severely rusted. And then I decided to further inspect the rotor surfaces. I removed the left rear tire and noticed that the back side surface was severely corroded therefore inhibiting the brake pad to stop with it. I remove the right rear tire and found the same condition! As I am retired, and still a ASE and Michigan master mechanic (XXX) I know this condition is abnormal for a vehicle with such low miles even in Michigan. This is my wife’s vehicle, and she noticed that the stopping distance was severely decreased over the months. With driving is treacherous as it is today she needs all the stopping distance that she can get. With the way the rotors were rusted, the rear brakes had no stopping power, and the fronts were minimal at best for surface for the pads to stop with. I checked the front and found the same thing on the inner surfaces of both front rotors. I decided it was time that I replace all the rotors and the pads as the surfaces of all rotors were beyond the point of turning them. I would never expect this to occur on a vehicle with such low mileage. I replaced the rotors and pads with all AC Delco components as I have faith in the design changes that are usually made to products in the same product family. For the rotors, I made sure that they were plated to stop any rust from occurring on the non-stopping surfaces. If anyone were to Google this vehicle, or it’s Cousin the Trax, you can see there are replacements either with coding or different material that prevents corrosion. I am glad I caught this in time as my wife’s safety was in jeopardy. One can see there is a fix for this issue, but the manufacture neglected to take any action to correct it.
