“Warranty,” “Vehicle Service Contract,” “Protection Plan,” and other similar terminology are often used interchangeably, but it’s important to know that they actually refer to different valuable coverages and benefits. GM’s Bumper-to-Bumper Limited Warranty covers specified vehicle repairs, including parts and labor, to correct defects in materials or workmanship. The Buick Protection Plan provides additional protection on top of the manufacturer’s limited warranty for your Buick’s engine, steering, and more. Ask your dealer about additional details and pricing.
