General Motors is facing a proposed class action lawsuit over allegations that certain Buick and Chevrolet vehicles contain a defective engine that can fail without warning, potentially causing a sudden loss of power and increasing the risk of an engine fire. The claims have raised concerns among owners who say they were left stranded by unexpected breakdowns and costly repairs.
What is the problem?
The lawsuit involves certain 2024 and newer Chevrolet Trax and Trailblazer models, along with the Buick Encore GX and Buick Envista, equipped with a 1.2-liter turbocharged three-cylinder engine. According to the complaint, the engines may contain defects that can lead to catastrophic failure, fluid leaks, and in some cases, engine-compartment fires.
Plaintiffs claim the defect can cause vehicles to lose motive power unexpectedly, creating a particularly dangerous situation if it occurs at highway speeds or in heavy traffic. A sudden loss of acceleration or power can leave drivers with little time to react and may significantly increase the risk of a collision.
The lawsuit also alleges that GM was aware of the issue through consumer complaints and internal reports but failed to adequately disclose the alleged defect to buyers. According to the complaint, the manufacturer issued technical service bulletins to dealerships but has not provided a permanent solution for affected owners.
What owners should do
Drivers who experience warning lights, unusual engine noises, fluid leaks, or a sudden loss of power should arrange an inspection as soon as possible. Owners should also keep records of repair invoices, dealership visits, and any communications with GM in case problems persist.
Consumers may also wish to monitor developments in the proposed class action and stay informed about any future recalls, warranty extensions, or service campaigns related to the affected engines.
