2018 Buick Encore Complaints

  • Fuel/propulsion System 07/15/2026

    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.

    Request for Goodwill Assistance – Turbocharger Failure (Special Coverage XXX) Dear General Motors Customer Assistance, I am writing to request a one-time goodwill repair for my 2018 Buick Encore (VIN: [XXX]). Approximately two months after purchasing this vehicle, the check engine light illuminated and diagnostic testing identified code P0299, indicating turbocharger failure. This issue appears to align with General Motors' Special Coverage Program XXX, issued in February 2024 for certain 2017–2018 Buick Encore vehicles equipped with the 1.4L engine due to known turbocharger failures. Unfortunately, my local GM dealership has informed me that they are unable to perform the repair under the special coverage because the vehicle carries a Pennsylvania reconstructed (R) title. While I understand the vehicle's title status, I respectfully ask GM to consider the unique circumstances. In Pennsylvania, reconstructed vehicles must undergo a rigorous Enhanced Vehicle Inspection process befo...

  • Steering, electrical System, service Brakes 09/15/2025

    I am filing a formal safety complaint regarding a repeated dangerous defect in my 2018 Buick Encore. The vehicle intermittently locks up while driving without warning. When this happens: brakes become unresponsive or lock steering becomes difficult or locks gas pedal does not respond dashboard warning lights activate vehicle systems malfunction vehicle may not shut off normally This defect has occurred multiple times and creates a serious crash risk. The vehicle has now undergone three repair attempts at an authorized Buick dealership. During the second repair attempt, dealership staff personally experienced the same malfunction while test driving the vehicle. I paid approximately $2,078 cash for repairs after being told the issue was fixed, but the same dangerous defect happened again afterward.The vehicle has remained at the dealership for 15+ consecutive days, causing loss of transportation and work hardship. I am also concerned by inconsistent repair documentation and possib...

  • Power Train 03/23/2026

The warning light remained illuminated while driving. The vehicle was taken to the dealer several times, however, the vehicle was not yet repaired. The vehicle was taken to the dealer to be repaired, but the failure persisted. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was 85,000.

  • Air Bags 02/08/2026

    The front passenger air bag sensor turns off either before we begin driving or while the vehicle is in motion. The manual says that if you have a seat cushion or are not in the position for the sensor to "see" you, it may turn off. I have a bad back, and I need my 2-inch seat cushion for long trips, or I will be in pain. But when I use my seat cushion, the sensor turns the air bag off. So, if I use my seat cushion (or the sensor otherwise decides to turn the air bag off), I am not protected in the case of an accident. If I don't use my seat cushion, I am in pain from my back. The front passenger air bag should have a manual switch and have the ability to be kept on all of the time, that decision being made by the passenger and not a sensor that is not smart enough to adjust to an additional cushion or other situation.
