The reason for the fluttering sound when accelerating the LaCrosse is due to insufficient power steering fluid, or it may also occur when decelerating. In short, the sound changes with the throttle, and its volume varies accordingly. Damaged generator bearings, issues with the power steering pump, or water pump can all produce similar noises. The LaCrosse is a car launched by Shanghai GM, with dimensions of 5005mm in length, 1858mm in width, and 1500mm in height, and a wheelbase of 2837mm. In terms of appearance, this car adopts Buick's new family design language, featuring smooth and elegant body lines and a highly dynamic body proportion. The wing-type full LED automatic sensing headlights use advanced light curtain technology to create a more uniform and brilliant light curtain effect.

Can the wipers be adjusted to slow down if they are too fast?

Wipers that are too fast can be adjusted to slow down. Most household cars have wipers with three settings: standard, fast, and slow, which can be adjusted, usually via the control stalk on the right side of the steering wheel. Different car models may vary slightly. Before using them for the first time, it's advisable to spray windshield washer fluid to wet the glass to avoid dry wiping if the window lacks moisture. Below is some related information about wipers: 1. Wiper Classification: Wipers can be categorized by their driving mechanisms into mechanical, vacuum, pneumatic, hydraulic, and electric types. Modern cars typically use electric wipers due to their simple structure and ease of control. Generally, car wipers consist of a motor, crank, linkage, wiper arm, and blade. 2. Wiper Function: Wipers are devices used to remove raindrops and dust from the vehicle's windshield, improving the driver's visibility and enhancing road safety. Due to legal requirements, almost all cars worldwide are equipped with wipers. Rear windows of hatchbacks and SUVs also often feature wipers.
