2017 Buick Encore

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.

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.

There is a problem with the 2017 Buick Encore turbocharger. From speaking with the auto shop I took it to for a check they have seen many Buick Encore’s with the same turbocharger problems. He spoke to me about it prior to me dropping off the vehicle and then confirming the issue after inspecting the vehicle. The turbocharger inspection revealed a distinct structural crack at the wastegate flange, resulting in boost pressure loss. There is already a recall associated with this problem in other VIN’s with the same year and type of vehicle, recall needs to be expanded because this is a known and ongoing problem.

UNKNOWN. MY 2017 Buick Encore while parked in front of my home just blew up at 1 am. I have a video of this occuring. It was on the passengers side. My neighbor stated that he heard a loud bang and went outside. He said parts were flying off my car. I don't know how to send the video but I do have one when this occured. I have contacted Buick Corporate and now they are saying that they are sending my matter to the legal department. Buick corporate told me to have my vehicle towed to the Buick Dealer which I did because I wanted to know why that happened. I paid to have it towed and tomorrow I have to pay to have it towed back home until legal gets back in touch with me. The way that the vehicle exploded I am scared to even get back into the vehicle. I am so thankful that this occured at 1 am and my grandson was in bed This could have really hurt or killed someone. I thank God that I wasn't driving it. When the tow truck driver arrived he said oh your air bag exploded . I told him that I didn't know what caused it. The Buick dealer never inspected the vehicle. The Buick dealer stated that it was the tire that blew from his visual inspection.

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 intake/manifold issue to GM for collateral coverage, goodwill review, or warranty consideration. Crivelli did not respond to the fax notice and did not return the customer’s calls. When the customer attempted to follow up with the service department, Scott from the service department refused to review the concern, refused to provide further service, and refused to contact GM regarding the related warranty issue. Based on the conduct, tone, refusal to review the documentation, refusal to escalate to GM, and refusal to provide equal service, I believe the customer was denied fair consumer service because of race.The customer is not asking for special treatment. The customer is asking for equal treatment, proper review of GM’s own warranty/special coverage bulletin, and fair handling of a related mechanical INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION A
