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.

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.

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 .

On 4/24/25 I noticed a pungent odor (like rotten eggs). The odor is worse today. I did research and it appears there may be a problem and or leak with the catalytic converter. The emissions are making me and my kids feel sick, nauseous, headache, irritated eyes, etc.

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
