ENGINE AND ENGINE COOLING
The contact owns a 2019 Buick Encore. The contact stated that while driving at various speeds, the vehicle hesitated upon depressing the accelerator pedal. Additionally, the vehicle hesitated to start after multiple attempts. The vehicle was taken to the independent mechanic where it was purchased, and the mechanic replaced the oxygen sensor. Despite the repair, the failure recurred intermittently. The contact stated that the check engine warning light illuminated, and the vehicle was taken to a second independent mechanic. Diagnostic trouble codes retrieved via an OBD-II scanner indicated catalytic converter issues; however, the mechanic determined the failure was related to the flex plate. The contact was referred to a dealer, where the contact was informed that the repair was not covered under warranty. The manufacturer was notified of the failure and assigned a case number. The contact was referred to the NHTSA Hotline to file a complaint. The vehicle was not repaired. The failure mileage was approximately 30,000.

ENGINE, POWER TRAIN
Sequential powertrain and turbocharger failure on 1.4L Ecotec engine following $5,700 in prior engine repairs. Vehicle experienced sudden loss of motive power. Component is covered under GM Special Coverage/warranty. Authorized GM dealer (Mike Haggerty Buick GMC) and General Motors have engaged in warranty evasion, refusing repair authorization and unlawfully retaining the disabled vehicle on the dealership lot for over 70 days. Furthermore, the dealership transmitted a false completed repair record to national vehicle history databases (CARFAX) on August 28, 2026, while the vehicle remained disabled and unrepaired on the lot.

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.

ENGINE, FUEL/PROPULSION SYSTEM
Not long after I purchased my car, i noticed it was lacking power during takeoff and when driving uphill which forced my car to hit very high RPMs during normal use. There was also a P0299 code that appeared then disappeared frequently. I discovered a turbo special coverage N232395330 and took it to Williams GMC in Charlotte. After i told them very clearly what happened MULTIPLE times, confirming the underboost and the code, I even brought it in with the code, they told me the code wasnt "active" and that there no problems...even after i told them I didnt feel safe and couldnt pull out at intersections with fear of being rear-ended. I had videos, they refused to look at and told me to come back when the code was permanent. I drove the vehicle for the next year, 20k miles in order to get the code permanent, after a trip home, through the mountains, really tough without the turbo, my car was consistently pinging 4-5000 RPM under the speed limit on inclines...this happened every time I drove through, but this time the code was active the entire time. 2-3000 miles with the code, finally it was permanent. I brought the car back to Williams GMC, to get the turbo changed. I updated them on recent occurrences, flashing check engine light, the code active for 2-3k miles, and they performed a road test, and declared it wasn't a problem. I told them i recently spent 5k on repairing my cooling and AC system because the turbo, they said that wouldn't affect those components, meanwhile i know they have plastic parts that can melt and the engine being forced to push 4-5k RPM the extra heat could easily melt those parts. They said, nothing was wrong and the road test was good. sent me on my way. I called corporate, they told me to get a second opinion. I did [XXX] found the problem and changed the turbo per the special coverage N232395330. a week later, my engine overheated, i pulled over and it wouldnt start, engin won't hold compression. Car is tot now. Long story shrt INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORM

STRUCTURE:BODY
We noticed the paint bubbling on one of her doors on the car and took it to the dealership who took no accountability. Now the car is peeling in the back and we’ve also noticed the same car, same model and make on the road with the same paint peeling issues that there’s no formal recall as of yet and we are not getting any resolution with GM.

ENGINE
General Motors issued a Special Policy N202299080 covering 2014 Buick Encores. My 2018 Encore had the same issues and symptoms as this Policy. My concern is because of this known problem the crankcase can be pressurized causing oil leaks which could cause a fire. General Motors issued a Service Information Bulletin 19-NA-114 in May 2019 about involving 2013 to 2019 Buick Encores. This is a known issue for many models other than my vehicle. I have the old parts from the repair for inspection which includes the Intake Manifold and the Valve Cover for faulty PCV components that cause the engine to produce excess Engine Crankcase pressure possibly causing a fire. My vehicle had a check engine light code of P0171 and the odor of burning oil.

Weber road auto service replaced the engine using county PRC and out-of-pocket funds, and the newly installed used engine has an active engine oil cooler leak, creating an immediate vehicle fire and sudden engine stalling hazard. Also there’s a leak at the ac compressor, condenser and coupler valves. This was discovered by Buckeye Auto Service. No repairs have been made as first shop keeps brushing me off.

ENGINE, FUEL/PROPULSION SYSTEM
The factory-installed turbocharger assembly on my 2017 Buick Encore failed mechanically while operating the vehicle, creating an immediate and severe roadway safety hazard.The structural failure of the turbocharger causes the vehicle to experience a sudden, unpredictable, and extreme loss of engine propulsion while actively driving. This severe power degradation makes it incredibly dangerous to accelerate, merge into highway traffic, or clear busy intersections safely, as the vehicle fails to respond to throttle input and drops speed rapidly. The vehicle is displaying an active diagnostic trouble code P0299 (Turbocharger Underboost condition).The manufacturer, General Motors, is fully aware of this exact component defect and has issued corporate Special Coverage Adjustment Bulletin N232395330 to address cracked turbo housings and wastegate failures on this model. However, because my vehicle is over their arbitrary 120,000-mile corporate warranty limit, GM’s Executive Resolution Team (Case #103125607) has issued a final refusal to repair the component.The manufacturer's mileage limitation leaves a documented, highly dangerous engine propulsion defect completely uncorrected on an active vehicle, posing a continuing, severe safety risk to the occupants and other drivers on public roads.

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

FUEL/PROPULSION SYSTEM
Strong odor of gasoline, followed by a crack in the high pressure fuel line. Gasoline poured out under pressure from fuel line approximately 1 foot ahead of the right rear tire. Major amount of spillage - literally several gallons within a minute or so, that eventually faded as the system lost pressure. Could have been a significant safety issue and catastrophic loss if there had been an ignition source nearby. Overall repair required dropping the fuel tank and the replacement of GM Part Number 95080144, a plastic fuel pipe. Overall, a safety issue and expensive (~$900) repair.

TIRES, TIRES:PRESSURE MONITORING AND REGULATING SYSTEMS
The contact owns a 2017 Buick Encore. The contact stated that while the vehicle was parked and unattended in the driveway in front of the residence, the front passenger’s side tire suddenly blew out. The tire pressure warning light was illuminated. The vehicle was towed to a local dealer, who was unable to determine the cause of the failure. The vehicle was not diagnosed or repaired. The turbocharger had previously become inoperative. The vehicle was towed back to the residence. The vehicle was towed to another local dealer, Boyd's Chevrolet (1875 Spartanburg Highway, Hendersonville, NC 28792). After three weeks, the dealer made an unknown diagnosis and replaced the tire. The manufacturer was notified of the failure and opened a case. The failure mileage was approximately 129,000.

On XXX, at approximately 1:00 p.m., my 2019 Buick Encore unexpectedly caught fire while I was operating it in [XXX]. Prior to the fire, I experienced abnormal symptoms, including the vehicle failing to restart, a hissing sound, smoke coming from the engine compartment, and then visible flames. The smoke changed from black to white and then green before the fire intensified. I safely exited the vehicle before the fire spread. The exact component that failed is unknown. Based on my observations, the fire appeared to originate from the engine compartment or underneath the front of the vehicle. The vehicle was declared a total loss. This incident placed my safety at serious risk because the fire occurred without warning while I was using the vehicle. Had I not exited when I did, the outcome could have been much worse. The incident also created a hazard to nearby motorists and anyone in the surrounding area. The problem has not been reproduced because the vehicle was destroyed by the fire. The vehicle was inspected by General Motors after the incident as part of a product allegation investigation. General Motors later informed me that it found “no merit” to my product allegation but refused to disclose the basis for its conclusion, stating that its investigation materials are confidential and proprietary. As a result, I still have not been provided with an explanation for what caused my vehicle to catch fire. I am submitting this complaint because I believe an unexpected vehicle fire is a significant safety concern that should be documented and evaluated.

UNKNOWN OR OTHER
Car purchased new in Nov 2018. Within 3 years needed a turbocharger replacement. At this time this was covered under warranty. Recently had to undergo replacement for the turbocharger again. This time it was not covered under the warranty. In researching this problem I saw that in Feb of 2024, Buick extended the warranty on the Buick 2017-2018 Encores, due to a manufacturer defect in the turbocharger. This add'lwarranty covered the cost of the repair & was good for up to 120,000 miles. Since we purchased the car in 2018, the parts used to build it had to be the same as those used on 2018 Encores. Asking to see what we can do to see if this car, under these circumstances qualifies for the recall.
