There are 1 owner-reported fuel system complaints for the 2020 Buick Encorein NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
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.
