92,000 miles my catalytic convertor went bad, had for 5 years. This resulted in lag when trying to accelerate and pull out in traffic. It cost $3,000 to fix as well as the turbocharger being broke. The blind spot detection to passenger side mirror stays on at all times and should only come on when there is an object detected in the right side blind area. I'm [XXX] old and have never ever has a catalytic convertor go bad. Buick should be responsible for these repairs.

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.

My check engine light has been appearing off and on for a few months. I received a diagnostic code of P0325 TWICE by two different professional technicians. I ordered an OEM knock sensor, hired a technician to replace the knock sensor, drove about 10 miles and the check engine light came back on. Then, I received a diagnostic code of P-1101, and the recommended solution is to replace the intake manifold and all necessary gadgets. After speaking with professional technicians and doing thorough online research, I discovered that General Motors issued a service bulletin No. 19-NA-101, dated July 2024, covers certain 2013–2019 model vehicles (including Buick Encore with 1.4L turbo) for oil consumption and/or leaks caused by a missing non-return valve in the intake manifold. The bulletin acknowledges that the intake manifold design on these 1.4L turbo engines has a non-return (check) valve or PCV system component inside the manifold that can fail or go missing, leading to issues like boost/vacuum leaks, oil consumption, engine performance faults. •The PCV valve is non-serviceable (you can’t replace it separately), meaning the only fix is replacing the manifold — which GM calls out in the bulletin. If GM or Buick hasn't issued a recall they should offer goodwill assistance especially since this is a defect on their end.

I have been calling Autonations for months now since my car started driving funny. I was first told it was a head gasket that needed replacement however using my vin number the engine that’s currently inside the vehicle is not the one that matches with what pulls up using the vin number. Than the antifreeze leaks out, the oil leaks out and one day the car started smoking on the freeway with my children and I inside. It just stopped and haven’t been working ever since. I literally just got messed out of money because I purchased this vehicle a year ago not knowing it was a recall and this is one of the recalls now I am completely screwed over without a car and my money!! Now I’m being told I have to pay because this car was sold to me already over the mileage limit to be fixed for free!!

My daughter owns a 2019 Buick Encore and the check engine light keeps going on. She took her car to the dealer and was told that it needed a Turbo Bypass Valve and Solenoid valve. The car is just a few months within the 10 year powertrain warranty and the dealer refused to cover as defect. She drives on the freeway 45 minutes to/from work and this is a serious issue that causes the engine to rev hard and not stop as well as stall intermittently.

My engine light came on. The repair shop said I have to replace the fuel pump control module and that it is a known issue with Buick. I was advised not to drive the car. I am concerned that I could have been out and the car could have broken down. The car doesn’t even have 50,000 miles on it. This should not happen.
