LANE DEPARTURE: BLIND SPOT DETECTION, FUEL/PROPULSION SYSTEM
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.

POWER TRAIN, UNKNOWN OR OTHER, VEHICLE SPEED CONTROL
I have had my vehicle to a GM dealer on a few occasions with the EMC code stored in the vehicle and an active check engine light on. While I’m driving - now during 70 percent or more of my trips - my vehicle loses power very suddenly and lunges me forward. I’m unable to stop and go on hills of any noticeable grade and have narrowly missed being in an accident many times. The dealer’s service manager has told me I should just BF glad the car is drivable when I have expressed ongoing safety concerns. I cannot get assistance from GM nor from the dealer in having this warranty connected part replaced. I do not have any other vehicle to drive, and I know I’m unsafe. I teach school and must get back and forth to work.

ENGINE, FUEL/PROPULSION SYSTEM
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.

POWER TRAIN, UNKNOWN OR OTHER
The EMC on the vehicle appears to be faulty. The vehicle is burning more than double the fuel than it should, and I’m able to smell a strong oil burning odor while driving it. The SUV lunges you forward violently when this defect begins to act up, which can be at any point in a short or longer trip. The vehicle has little to no power once this is triggered and seems to go into limping mode. I’ve had this to a dealer three times, and they have failed to repair the issue. The first time I left it there for almost a month and within three miles of the dealership, the same problem happened. The dealer denies that the repair should be covered under the emissions regulation, which makes GM-BUICK responsible for repairs of this equipment until 8 years or 80,000 miles.

FUEL/PROPULSION SYSTEM
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 have went to the dealership for the past two years with this problem and they keep saying they are not getting any codes: when the air conditioner is on it’s pulling the power from the motor and makes it hard to go up hill. Hard To accelerate when going on to the freeway as well. The problem is only getting worse and worse.

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!!

POWER TRAIN, ENGINE
•On January 25th 2025 I paid approximately $3,383 for a turbocharger repair on my 2019 Buick Encore. This included a turbocharger oil return tube, turbocharger oil supply and re, intercooler, int. man. & vAL. COV. Kit, R&R inter cooler, R&R turbocharger, R&R intake manifold, and turbocharger assembly. Since that time, the same problem has recurred and I have returned the vehicle to the same location on four separate occasions without resolution. It is currently available for inspection. •August 11th, 2025: Vehicle stalled in the middle of an intersection as I attempted to accelerate from a stop sign, placing me in immediate danger of collision. •I have had the check engine code read by another independent service center. •No one else has inspected the vehicle •The check engine light has come off and on since January when the problem began after visiting Mavis Discount Tire in sinking spring for a routine oil change. There were no symptoms prior to this first failure that signaled the issue that resulted in the repair. Prior to the incident on August 11th there had been repeated symptoms of an issue even when the check engine light was off. These issues included overheating, smoking, lack of acceleration, and stalling.
