2017 Buick Encore problems

“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…”

“While traveling at approximately 77 mph on the interstate, I was forced off the road by another vehicle, causing my car to collide with a cable barrier. The initial impact was to the front driver’s side corner, and the vehicle then scraped along the driver’s side against the barrier. Despite the high-speed impact, no airbags deployed. •Component or System That Failed: The frontal airbag system failed to deploy. •Safety Risk: The non-deployment of the airbags at this speed and impact angle posed a serious risk to my safety. The lack of airbag activation during a high-speed frontal crash greatly increased the likelihood of injury. •Has the Problem Been Reproduced or Confirmed by a Dealer or Independent Shop? No. The vehicle has not yet been inspected by a dealership or repair facility, and the issue has not been confirmed or diagnosed by a professional. •Has the Vehicle or Component Been Inspected by Manufacturer, Police, Insurance, or Others? No. The vehicle has not been inspected by the manufacturer, police, insurance representatives, or any other party as of this report. •Warning Lamps, Messages, or Symptoms Before the Incident: No warning lights or messages…”

“Formal Consumer Complaint Statement — GM / Crivelli Buick I am filing a formal consumer complaint against Crivelli Chevrolet Buick GMC and General Motors/Buick regarding what I believe was discriminatory and unfair treatment in connection with a warranty-covered vehicle repair. The customer is [XXX] , owner of a 2017 Buick Encore. The vehicle was serviced by Crivelli Chevrolet Buick GMC in Mt. Pleasant, Pennsylvania, on or about May 20, 2026, for a turbocharger failure covered under GM Special Coverage Bulletin N232395330. The vehicle had recently passed Pennsylvania safety and emissions inspection on April 30, 2026. The turbo-related diagnostic code appeared on or about [XXX]. Crivelli completed the minimum turbocharger warranty repair but then informed the customer that additional intake/manifold-related repairs were needed and would not be covered. The customer disputed this because the additional failure appeared during the same repair sequence and appears directly related to the covered turbocharger failure. A written request was faxed asking Crivelli to review the invoice, compare the repair to GM’s covered parts list, and submit the related…”

“I have went to the dealership for the past two years with this problem and they keep saying they are not getting any codes: when the air conditioner is on it’s pulling the power from the motor and makes it hard to go up hill. Hard To accelerate when going on to the freeway as well. The problem is only getting worse and worse.”

“THE VEHICLE STARTED MAKING NOISES AND THE INSTRUMENT PANEL AND SCREEN WENT OUT. THE VEHICLE WAS DRIVABLE, BUT THE ENTIRE INSTRUMENT PANEL WAS OUT.
