2019 Buick Encore Complaints

FUEL/PROPULSION SYSTEM,LANE DEPARTURE — Filed 09/01/2025

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.

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.

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.

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.

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

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.
