2019 Buick Encore Complaint Log

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.

Car sputtered and slowed on expressway, turbo failed. Recalls issued 2016 and 2017, then reissued 2020 to 2023, same turbo, 2019 was exempted

The contact owns a 2019 Buick Encore. The contact stated that while driving at various speeds, the check engine warning light remained illuminated, with the odor of burning oil inside the cabin of the vehicle, before the vehicle stalled. The vehicle was taken to a dealer who diagnosed the vehicle and determined that the valve cover, intake manifold, and oxygen sensors were faulty and needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 63,360

The contact owns a 2019 Buick Encore. While driving at an undisclosed speed, the check engine warning light illuminated. The vehicle was taken to a private mechanic, who diagnosed the vehicle with a blown turbo charger caused by low oil pressure. The contact stated that the turbo charger was previously replaced due to the same failure. The contact stated there was a recall for the for 2017-2018 Buick Encore for the same issue; however, the 2019 model year was not included. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 63,500.

turbo charger and catalytic convertor both failed at 50k miles. the 2017 and 2018 buick encores have a safety recall for turbochargers but the 2019 was not included in that recall despite it having the exact same engine and turbocharger.

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.

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.

When I'm driving sometimes the car seems like it's about to cut off or something & the check engine light plus stabilizer track message bones on & I start losing power & it's happened more than 10 times ! I let the car sit for a few minutes & it works !

The contact owned a 2019 Buick Encore. The contact stated that while her daughter was driving at 35 MPH, another vehicle failed to yield at a left turn, driving northbound, and crashed into the contact's vehicle on the front driver's side. The air bags did not deploy upon impact. The contact's daughter and granddaughter were both injured and were later treated at the local hospital for soreness in various parts of their body. Both occupants sustained emotional trauma as a result of the accident. The other driver was also injured as a result of the accident and was transported to the hospital by ambulance; their injuries are unknown. A police report was filed. The vehicle was towed from the scene to an independent tow yard, where it was deemed a total loss. Neither the dealer nor the manufacturer was notified of the failure. The vehicle was destroyed. The failure mileage was approximately 135,000.

The contact owns a 2019 Buick Encore. The contact stated that after the vehicle was stopped, the gear shift lever was stuck in park(P). After several attempts, the contact was able to move the gear shifter lever. The contact stated that the drive back to the residence was rough. Two or three days later, the gear shift lever failed to function as intended. The service warning light was illuminated. The vehicle was taken to an independent mechanic who diagnosed and retrieved DTC: P171D (For transmission pressure issue and oil leak). The vehicle was not repaired. The vehicle was taken to the dealer, where the contact was provided with the same DTC and informed that the transmission had failed and was leaking fluid. The vehicle was not repaired due to the cost. Upon further investigation, the contact learned that the failure might be related to missing bolts on the transmission accumulator. The vehicle remained at the dealer unrepaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 77,000.

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.

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.

The contact owns a 2019 Buick Encore. The contact stated that while his daughter was driving approximately 35 MPH and following the roadway to the left, all the side air bags deployed unexpectedly. The contact stated that his daughter was not aware of any warning lights being illuminated during the failure. The contact had the vehicle towed to a local dealer; however, the vehicle was not yet diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 40,000.

•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???

The contact owns a 2019 Buick Encore. The contact stated that while her daughter was driving approximately 55 MPH, the vehicle was shaking and jerking abnormally. The contact stated her daughter reported there were several unknown warning lights illuminated on the instrument cluster. The driver exited the highway and pulled over and turned off the vehicle. The contact had the vehicle towed to a dealer. The dealer diagnosed the vehicle and determined that there was coolant intrusion into the cylinders, and the engine needed to be disassembled. The vehicle was not repaired. The manufacturer was informed of the failure. The failure mileage was approximately 103,000.

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.

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

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!!

The contact owns a 2019 Buick Encore. The contact stated that while attempting to accelerate from a stoplight, the engine revved up before accelerating. While the vehicle was accelerating, the check engine warning light illuminated. The vehicle was taken to a certified mechanic, who diagnosed that the wastegate for the turbocharger was stuck, causing the turbocharger to fail. The contact was informed that the turbocharger needed to be replaced. The vehicle was not repaired. The contact became aware of a TSB for 2017-2018 Buick Encore vehicles under TSB Number: N232395330; but the 2019 Buick Encore was not included. The manufacturer was not informed of the failure. The failure mileage was 68,000. The VIN was not available.

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.

Transmission whirring, vehicle is skipping while driving, gear/rpm not downshifting after acceleration

I've only had the car for under a month and twice this has happened. When I came to a stop, the start/stop system was activated (engine shuts off) and I put the car in P (parked). Then when I placed it into reverse and released the brake which started the engine, there was a huge jolt/jerk/buck. This happened twice and as far as I know this these are the only times I've committed this specific sequence of events.

The full type of this tire is Continental ContiProContact P215/55 R18 94H Also DOT is IP5 OF8PAO 5323. Note there are two letter "O". Either one or both of those could be the number 0. I cannot tell the difference on my tire. When I was driving in a parking lot I heard a loud noise and did not know what it was. I did not think to look at my instrumental panel so I drove around a half mile home. Then I noticed the TPMs warning and saw that the tire was completely flat. I saw sidewall damage that look like something cut into my side wall or perhaps that was the blowout. It was cut about a half inch or inch long in the outside sidewall of the tire. The tire only had about 821 miles on it. I check the pressure consistently and it always was the proper pressure as specified by the vehicle door jamb. Also my vehicle shows me the exact tire pressure when on the instrument panel. I checked it the morning before the blowout happened and the tire pressures were fine. Also I look at my tire pressure almost every time I drive (about every day) using the tire pressure indication on my instrument panel. I never hit any potholes or any curbs. The tire looked normal and felt fine when I was driving on it (until the blowout of course). Also according to the DOT it was manufactured late 2023 so it does not sound like dry rot. This seems like it could either be a manufacturing defect or installation defect of some sort. A blowout obviously is a safety risk since this could have happened on a busy highway. Luckily I got home safely. When I brought it in to the dealer for repair they thought maybe something hit the tire from the outside. I believe the dealer got rid of the tire so it would not be available for inspection. No warning before the failure occurred.

my car engine did not shut off i had to call on star to assist turn off my engine. there is problem with ANTI theft system and cruise control. i had to press cruise button numberous time to shut it off. on start customer advice me to take it to dealer to take look. they did on board diagnosit test they found these code

Rear Deferential Housing Cracked

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.

My radar to let me know i was going to hit something didn't go offer. It has never failed before and has been overactive actually which I appreciated before. I was doing 60 with my paraplegic wife (luckily not our 5 year old as well though) in the right lane because it's safer to go slower and be there. I was distracted by a strange machine being transported on a truck to my left. This was my fault. I hear the ultimate responsibility and the majority if not all of it. I saw the road construction trucks 400 feet ahead of me at most. Maybe less than 300 and luckily no one was to my right the truck distracting me was ahead so I had room to avoid hitting the construction truck with the sign saying move over. It was doing maybe 15. I almost killed my wife. It was my fault but still the $3000 safety package failed. Almost catastrophically.

Tire pressure warning came on on highway and FL tire went flat in seconds, pulled over to the shoulder. Tire had ruptured sidewall and apparent dry-rot. Tire shop checked all other 4 tires and all show clear signs of dry rot (cracked rubber) on side wall. ContiProContact P215/55 R18, failed tire DOT LMOA BN7 0718. Other tires 1x same DOT and 2x : LMOA BN7 0618. Tires are OEM, original with vehicle purchase. Vehicle mileage 44220. Replaced all 4 tires already but have pictures of all original.

On highway pressure warning come on and within seconds tire ran flat. AAA service said sidewall was split due to dry rot. Vehicle has 40k miles. Tires are OEM.

Catastrophic control arm failure. The part is available for inspection. Problem confirmed by certified technician at Brake Master repair shop in Santa Fe NM. No visible damage to control arm prior to catastrophic part failure from apparent metal fatigue. Only 37,000 miles on this 2019 Encore. There were no indications of this problem prior to the part failure. The vehicle began making a loud clunking noise and heavy physical clunk when the brakes were applied. Because of the possible safety concerns I had the vehicle towed to the Brake Master facility. Upon inspection the control arm was seen to be broken in two. I took the problem part to the Octane GMC/Buick dealership in Santa Fe where the vehicle was purchased new and showed the part to one of the mechanics who informed me that he had seen this happen before. As this is a relatively small dealership I thought that it was significant that this mechanic had seen this failure previously. Got me wondering if GM is having this problem not only with the Buick Encore but possibly with its twin in the Chevrolet product line. Repair estimate from Brake Master [XXX], $634.91. Service advisor 3717-Caesar Sanchez Description of damage: Front Right control arm broken-ripped apart. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The airbags never deployed. I sustained a brain injury in the accident along with whiplash. I told the deputy on scene, that they did not deploy. My insurance looked at it. They totaled the car out. It is now sitting in a junk yard somewhere.

When I apply brakes the car accelerates instead of stopping. This occurs randomly and not all the time. It has occurred at traffic lights or when I am at a location to park the suv. I was in a accident in May which caused damages to another car. I reported this to GM back in May of this year and they stated that they sent a engineer to inspect the car and could not find anything wrong. at that time the car had been towed to the dealership. I went and picked the car up It drove fine for a while and now its back doing the same thing again. It will run thru red lights, stop signs and doesn't stop when I pull into parking spaces, this is very dangerous, I am getting the run around with General motors. I need some one's help before someone gets injured or killed with this vehicle. I hope its not me.

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.

Right Rear Wheel locked up (froze) while operating vehicle in cold conditions (mid 20's) - brake caliper froze - ruined rear tire

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

The contact owns a 2019 Buick Encore. The contact stated while driving at approximately 55 MPH, the power steering failed to function as needed. The contact pulled off the roadway into a parking lot, placed the vehicle in park, turned off, and restarted the vehicle. The contact stated that the power steering resumed normal functionality. The contact stated that the power steering warning light was illuminated. The contact had not taken the vehicle to a dealer or independent mechanic to be diagnosed or repaired. The contact stated that the failure had occurred only once. The manufacturer had been informed of the failure. The failure mileage was approximately 45,500. The VIN was not available.

For no apparent reason my air bag sensor light comes on intermittently while driving.

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.

10/26/2022 Dealer inspection of vehicle brake system. Owner concerned with pulsing sensation at higher speeds when braking. Dealer discovered 'uneven pad wear on front axle and rear rotors worn and have excessive thickness variation.' Dealer 'recommends front and rear brake job.' Vehicle has 23,600 miles. Brakes are wearing excessively for low mileage. Dealer verbally recommended future inspection of brake system at intervals of 15,000 miles. Vehicle has been owned for 40 months. Outside of warranty by 3 months. Average of 7900 miles driving per year.

When I pulled into a parking space at docs office, my car suddenly lurched forward very fast, over the curb and into rocks. I had foot on brake and put in reverse, only to have it reverse very fast and hit a parked car! I was shocked! It had a mind of its own! This has never happened before. I do recall that sometimes when I back out of garage at home, I keep foot on brake and it seems like it wants to “go”. I read on a website that another Encore had very similar incident as mine. My son found online “Transmission slipping” problems with Buicks. I am so thankful no one was walking in the parking lot at the time it happened. Problem has not been reproduced.. police officer didn’t know if there was any recalls for this either. I put a claim in with State Farm and they recommended an auto shop to go to, a few blocks from my condo. I went today (Carstar auto) and they looked at damage. They are trying to order parts for it. He said I can drive it, but honestly, I am afraid this will happen again. I have to go to work, so I’m hoping this doesn’t happen again. I don’t know what to do. The only warning I had on dashboard was to replace the battery in my key fob. I went to O’Reilly’s Auto Store and bought battery and My friends adult son replaced it for me. Most damage is to rear. Some in front underneath I can’t see. Man at Carstar auto saw it.

This auto has 34,000 on it. The problem is sudden acceleration. This would be the third time this happen for this auto. If there are any questions that you might have my email address is [XXX].
