1 Answers
The first scenario is a vacuum booster pump leak or malfunction, while the second scenario occurs when the brake is pressed after the engine is turned off, which is also related to the brake booster pump. Below is some relevant information about the Envision: 1. Design: The Chinese name for the Buick ENVISION is 'Angkewei' (Envision). As a new-generation strategic model under General Motors, the Buick Envision inherits the design essence of the ENVISION concept car, featuring a dynamic, elegant, and sophisticated overall styling. 2. Exterior: The front end adopts the brand's signature waterfall-style chrome grille, complemented by wing-shaped intelligent xenon headlights, boomerang-shaped LED daytime running lights, and streamlined exterior mirrors, creating a sharp and sporty visual effect. The body features a fully-framed chrome window design, along with roof-line-following aluminum roof rails, paired with class-leading 19-inch oversized alloy wheels, delivering a striking visual impact.
