LaCrosse 2.4 engine yellow light constantly illuminated indicates that there is a fault in the engine. This fault does not affect the normal operation of the engine, but it requires timely inspection and repair. The core part of a car is the engine, and the health status of the engine directly affects the driving safety of the entire vehicle. Once the engine malfunctions, the engine fault light on the vehicle's dashboard will remain lit. The LaCrosse is a new mid-to-high-end sedan launched by SAIC-GM, with body dimensions of 4902mm in length, 1863mm in width, and 1461mm in height, and a wheelbase of 2829mm. The LaCrosse is equipped with GM's 1.5T SIDI direct-injection turbocharged engine and a 9-speed HYDRAMATIC intelligent transmission, providing consumers with a richer selection of mid-to-high-end vehicles.
