The LaCrosse brand was introduced by Buick during the 2005 model-year. The LaCrosse replaced two vehicles in the Buick lineup: the Century and Regal. During the 2010 model-year, the Buick LaCrosse was in its third generation. All three generations have been equipped with a braking system that, although reliable, can be prone to typical brake problems.
A recall was issued by General Motors, the parent company of Buick, on Apr. 15, 2005 for all LaCrosses produced that year. The brake pedal would not engage the brakes, which could result in a crash. The recall was issued by the National Highway Traffic Safety Administration (NHTSA) as Campaign Number 05V156000.
If the brake pedal has little to no resistance and goes to the floor when depressed, this indicates either insufficient brake fluid in the system, a bad brake master cylinder or an air bubble in the braking system.
If the brake pedal feels soft, spongy or loose, this may be caused by loose bolts on the brake master cylinder mount, a bad brake master cylinder or an air bubble in the braking system.
If you hear a squealing or whining noise when engaging the brakes in your Buick LaCrosse, this is most likely caused by a worn brake pad. If the noise is audible while driving but goes away when the brakes are depressed, this may be caused by the buildup of brake dust.
If the Buick LaCrosse pulls to one side during braking, this may be caused by incorrect tire pressure, poor wheel alignment, restricted brake lines or a malfunctioning brake caliper.
Pulsations, during braking, can be caused by worn or warped brake rotors.
