There are 1 owner-reported fuel system complaints for the 2019 Buick Encorein NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
85,000 miles bought new. Was having hesitation and power issues, experienced increased fatigue the longer I drove. Took it in for service at 85,000 miles and the turbo PVC valve was bad as well as the catalytic converter. I’ve never had a catalytic converter go bad on any vehicle in my 42 years of driving. Cost = $2,000 for just the catalytic converter and extended warranty covered. Advised at time of being repaired that blind spot monitoring on right side of passenger mirror was malfunctioning. The dealer insisted I make a separate appointment which is another $100 co-pay so they can fix it. I was told the insurance company may delay or deny the claim. I know that can’t be true but my boyfriend has cancer and need the vehicle back asap for his treatment transportation. Sounds like problem with Encore.
