Windham, NH

ENGINE

Loss of acceleration due to cracked turbo boost. I guess you need a special 2019 vin # to be included in a recall. Recall for 2017 2018 and a select few 2019 very disappointed with this big repair job that is a known problem. I'm done with Buick.

Turbo boost failed. shows recalls for this issue on 2018 and 2019 Buick Encores, but GMC states mine is not covered.

Fort Payne, AL

ENGINE

Car has airbag light on. The car keeps leaking which then caused damage to my spark plugs and coil pack. It then led to the O2 sensors being burned. It has been at the dealership multiple times within a 3-week time frame. The low fuel light comes on when it is on a full tank, then it begins to hesitate and the car lunges forward when at a complete stop. Tires act like they cannot keep traction when all 4 tires are brand new and front rotors and brakes have been replaced. Yes, all my concerns have been brought to many dealerships' attention. It is unsafe and unreliable. The dealership said they could not replicate the issue but once I get back into my car it starts up.

Columbus, OH

ENGINE

My check engine light continues to turn on and the code is related to the wastegate actuator/turbo charger. My car is running rough and doesn't accelerate properly. It sometimes rocks back and forth when I try to accelerate. Which is a KNOWN PROBLEM WITH BUICK. GMC REFUSES TO RECALL THIS WELL DOCUMENTED ISSUE. And naturally, it becomes an issue after the warranty expires. Mileage: 67,067

3 leaks in oil cooler. When mech got in to do the repairs, they noticed the turbo was cracked. Replaced it with new turbo which also failed. After the second new turbo was installed the car ran fine for about a day and now the turbo continuously stalls while driving it.

Jacksonville, AL

ENGINE

SUV has ran hot and had it towed on 3 separate occasions when this happened. Had thermostat and water pump replaced. Not fixed. Coolant keeps running out if bottom of suv. It is at dealership and blown head gasket and probably much worse. Apparently these models have something wrong with cooling system. The engine cost will be about what I owe on it. Buick needs to pay for another engine for my SUV. I have a warranty but they won’t honor the engine replacement and I’m out of a vehicle.

Eagle River, AK

ENGINE

Driving down the road and car became sluggish to respond/accelerate and could barely operate at slow speeds or not be able to go. Thankfully at this time I was close to home and not on the highway but was leaving on a long trip with areas of no service and isolation and temps in the -20F could be a very dangerous situation. There were no warning lights on at all. But I own a code reader and hooked it up anyways and got code P0299. Took it to a small local repair shop and will include their report as a file because I don't understand all of it but this is a known issue/defect from the manufacturer with a technical bulletin out about it with a fix for it. Was never notified of this at purchase or since. Then took to the manufacturer dealership to try and get them to fix it but they won't and want more money than the small shop. Feel misled when headquarters said yea we should cover that move it to a dealership.

Chicago, IL

ENGINE

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!!

Wernersville, PA

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.

ENGINE

turbocharger failures, which can result in reduced acceleration, power loss causing problems while trying to merge onto traffic and also in hill climbing. My understanding this is a common problem with the Buick Encore and has not been recalled. My garage said they have repaired a "ton" of these turbo in Buick Encores. Why no recall???

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.

Columbus, NC

ENGINE

On Wednesday June 28th, 2023, I was returning home to Columbus, NC from Charlotte, NC. I was travelling on Hwy. 74 and on the west side of Shelby my 2019 Buick Encore started sputtering and did not have any pick up. I stopped at Friendly Chevrolet in Forest City, NC, just off Hwy. 74 and they tested and said I had a mis-firing engine and should not drive due to safety issues. They could not fix as it is under Buick warranty and they are not a Buick dealer. I slowly drove the 20 miles home and feared it would stop at any time. Fred Anderson Chevrolet, where I purchased the car in 2020, is located in Greer, SC. I am still under full warranty so it was towed there and is still there. This was a very scary situation, as I was in the middle of nowhere. I am an 80 year old female and was very anxious as to what was going on and I still owe $10,000, on the car and fear it may have more major problems before the warranty expires in November 2023. Please advise and help me with this. Thank you, [XXX]. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).
