What Causes the Engine Warning Light to Illuminate in the Envision?

[StJace]

The reasons for the engine warning light illuminating in the Envision are: 1. Insufficient engine oil, leading to inadequate lubrication of cylinders and pistons, affecting their normal operation; 2. Overheating of the engine, causing it to operate under excessive load; 3. Engine misfire, preventing the engine from functioning properly; 4. Severe engine carbon buildup, clogging the vehicle's fuel system and preventing complete fuel combustion; 5. Low-quality fuel or the use of an incompatible fuel type. The Envision is a midsize SUV under SAIC-GM Buick, with dimensions of 4686mm in length, 1839mm in width, and 1686mm in height, and a wheelbase of 2750mm. The vehicle features a new winged chrome trim that runs through the LED winged headlights, broadening the horizontal visual effect. The rear also adopts a three-dimensional winged design, with chrome trim connected to the taillights, paired with integrated dual exhaust pipes to enhance the sporty feel.
