2019 BUICK ENCORE Engine Problems

Turbocharger gasket failed resulting in leaking coolant and overheating of engine. Damages resulted turbocharge replacement and replacement of water outlet in $4463.43 repair bill.

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.

My suv dies while im driving it. The engine stalls the lights go off. Its very dangerous I had a semi truck behind me last night and my encore basically became invisible. No lights no power, nothing. He almost hit me. Ive had this encore to several mechanics and none of them knows what the problem is. There are no warning lights on and it does not show any codes when hooked up to a diagnostic machine. I have called Buick Corp.and she told me to take it to a mechanic.

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!!

•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.

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???

They sold me a car and 2 days later the check engine light came on I fixed it then a second time it came on I fixed again then a third time it came on I fixed it again now this is the 4th time that this light has come on and I called up there they tell me well we can see about putting you in another car. I go up there today and they tell me well the loan place you chose won’t do it because what’s on my credit so I ask if they can fix it for free because I can’t afford to pay 500$ 9’ car note and 500$ for car Insurance they said it’s nothing they could do to help me I asked for a manger Chelsea , she walked passed me 3 times and one of the times was to go smoke a cigarette didn’t even try to aknowlege me until I called my salesmen Veronica too say she walked passed me 3 times and didn’t say anything I don’t appreciate im working hard to try and pay for this car and. I felt as if no one cares I feel as if I was sold a lemon and they continue to say well we didn’t sale you a lemon how would you know if it’s a lemon or not prior to buying know one knows that

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.

I brung my car in due to a oil leak and a water pump (Coolant leak) amongst other things my check engine light stays on its the turbo charger, Oxygen sensor and exhaust manifold. this has been an ongoing issue since I purchased the vehicle.

I haven't drove my car in 2 years because the engine and a/c went out on a vehicle that only have 67,000 miles. I should not have to replace a whole engine and a/c when I got the car brand new off the lot. This is my second buick that has had serious problem GM IS SELLING LEMONS TO THERE CUSTOMERS AND IM LOOKING TO STARTING A CLASS ACTION LAWSUIT IF THIS IS NOT FIXED.

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).

On six occasions the vehicle stalled in moving traffic. The car had to be stopped, placed in park and restarted. Buick Service repair in Johnston, Rhode Island cannot repair. The car has been taken to them 6 times with no resolution.

I got my car from Buick of Long Island City I was giving the wrong key mess up battery the car will not start and I crashed

At approximately 1130am, pulling into parking space in a parking lot at very low speed, 50% of vehicle was in the parking space, when suddenly the car accelerated forward. This resulted in my vehicle jumping over a safety curb and crashing into a building resulting in damage to my vehicle.

MY CHECK ENGINE LIGHT CAME ON, AND THE BEHICLE HAS BEEN DRIVING ROUGHER. IT JOLTS FORWARD WHEN YOU TAKE YOUR FOOT OFF THE BRAKE FROM A FULL STOP, MORE THAN NORMAL.

WHILE DRIVING DOWN THE ROAD THE VEHICLE TURNS ITSELF OFF. HEADLIGHTS GO OFF AND THERE IS NO CONTROL OF THE VEHICLE. SOMETIMES THE VEHICLE WILL CRANK ITSELF WITHOUT TOUCHING THE START BUTTON. SOMETIMES SEVERAL TIMES BEFORE IT WILL REMAIN ON LONG ENOUGH TO START DRIVING AGAIN. IT IS VERY DANGEROUS TO DRIVE BECAUSE YOU HAVE NO CONTROL OVER THE VEHICLE AT THE TIME OF ENGINE SHUTDOWN. IT DOESN'T MATTER IF IT IS HIGHWAY SPEEDS OR IN TOWN. TONIGHT IT TOOK OVER 2 HOURS TO TRAVEL A NORMAL 20 MINUTE DRIVE. IT ALL STARTED 27 FEB 21 AND TODAY (28 FEB 21) IT IS PROGRESSIVELY GETTING WORSE. MOST OF THE TIMES THAT IT HAPPENS A BELL WILL DING 4 TIMES AND RIGHT AFTER THE BELL CHIMES THE ENGINE IMMEDIATELY SHUTS OFF. ALL LIGHTS EXTINGUISH, IT LOSES STEERING CONTROL AND BRAKES ARE MINIMIZED.

I STARTED TO PULL INTO THE INTERSECTION. A GIRL TRAVELING EAST TO WEST DIDN'T STOP AT HER STOP SIGN. WHEN I GOT IN THE MIDDLE OF THE INTERSECTION, SHE HIT ME. THE SPEED LIMIT WAS 45 MPH COMING FROM HER DIRECTION, BUT I DO NOT KNOW HOW FAST SHE WAS TRAVELING. SHE HIT MY CAR AND IT SPUN MY CAR. I REMEMBER HITTING MY HEAD 2 TIMES ON THE SIDE WINDOW AND MY BODY TWICE AGAINST THE DOOR. MY AIRBAGS DIDN'T DEPLOY. MY CAR FACED THE AIRPORT WHEN IT CAME TO A STOP AND WAS FACING WEST.

I WAS STOPPED IN A DRIVE THRU TACO BELL AND THE CLERK DROPPED MY CHANGE DOLLARS FROM MY PURCHASE SO I REACTED BY OPENING THE DOOR TO PICK UP THE MONEY BY TAKING MY FOOT OFF THE BRAKE WITHOUT PUTTING IT IN PARK BECAUSE IT WAS A REACTION. THE CAR'S STOP START FEATURE SURGED THE CAR FORWARD PINNING MY LEGS BETWEEN THE CAR AND THE BUILDING. I COULDN'T PUT THE CAR IN PARK BECAUSE MY LEGS WERE PINNED AND THE VEHICLE SHIFT WOULD NOT GO INTO PARK. I SCREAMED AND THE CLERK HAD TO TAKE MY SHOES OFF SO I COULD PULL MY LEGS IN THE CAR. I WENT DIRECTLY TO URGENT CARE. MY LEGS WERE SEVERELY BRUISED. THIS IS A MAJOR SAFETY ISSUE. THE CAR SHOULD NOT SURGE FORWARD LIKE THAT. I'VE HAD THE CAR FOR 1 MONTH AND IT SCRAPED THE DRIVER SIDE DOOR AND FRONT TIRE/RIM. $1500 DAMAGE BUT LOST A DAYS WORK AND SEVERAL WEEKS OF RECOVERY. THE SAME THING COULD HAPPEN AT AN ATM. I USED TO WORK FOR GM AND TEST DRIVE VEHICLES THIS ENGINE STOP/START FEATURE SHOULD HAVE AN ELECTRIC FEATURE SIMILAR TO WHAT FORD HAS THAT ONCE THE DOOR OPENS, THE DRIVE GOES AUTOMATICALLY TO PARK. THIS SHOULD BE A SAFETY RECALL!!! 10/8/19.

I WAS STOPPING TO PARK THE CAR AND TOOK MY FOOT OF THE BRAKE BEFORE I PUT THE CAR IN PARK, THE CAR SURGED FORWARD OVER THE CURB, A SIDE WALK AND INTO A ROCK GARDEN, (I WAS PARKING AT A NURSERY) I HAVE NEVER EXPERIENCED ANYTHING LIKE THAT BEFORE. I THINK IT HAS SOMETHING TO DO WITH THE 1.4L SIDI TURBO ENGINE WITH ITS START-STOP TECHNOLOGY. I THINK IT IS EXTREMELY DANGEROUS AS THE ENGINE SURGE WAS STRONG ENOUGH TO PROPEL THE CAR OVER THE CURB, A SIDE WALK AND INTO A GARDEN. I BELIEVE THAT THIS TECHNOLOGY WILL CAUSE A LOT OF REAR END COLLISIONS. ALTHOUGH NO OTHER CAR WAS INVOLVED IN MY CASE AND I WAS NOT HURT BUT IT DID ABOUT $ 9000 WORTH OF DAMAGE TO THE UNDERSIDE OF MY CAR BECAUSE OF THE ROCKS THAT THE CAR TRAVELED OVER BEFORE I STEPPED ON THE BRAKE. THE DISTANCE IT TRAVELED WAS PROBABLY 6 TO 8 FEET BUT IT SCARED THE DELIGHT OUT OF ME!. I DON'T KNOW IF THE ENGINE CAN BE MODIFIED SO THAT THE SURGE IS NOT THAT STRONG SO THAT IT PROPELS A CAR FORWARD AT SUCH A HIGH SPEED. I ALSO DON'T KNOW IF YOU HAVE RECEIVED ANY OTHER COMPLAINTS OF THIS NATURE BUT WOULD LOVE TO KNOW. I HAVE HAD THIS CAR ONLY A FEW MONTHS AND AM AN EXTREMELY CAREFUL DRIVER. I HAVE ONLY HAD ONE OTHER ACCIDENT IN THE 40 PLUS YEARS THAT I HAVE BEEN DRIVING AND THAT WAS NOT MY FAULT. HOPE TO GET A RESPONSE AND THANK YOU FOR LETTING ME VENT.
