Certified Service for every road ahead

Consult your vehicle Owner’s Manual for the manufacturer’s suggested oil-change interval. Engine oil breaks down over time; so even if the specified mileage has not been reached, auto manufacturers recommend changing the oil regularly. If your vehicle is equipped with an oil-change monitor, you’ll see a “Change Engine Oil Soon” message in the driver information center, alerting you that you should have the engine oil changed within the next 600 miles. The engine oil and filter must be changed at least once a year, even if the “Change Engine Oil Soon” message is not activated within a year.

If your vehicle requires service, we recommend that you call your preferred dealership or visit your dealership’s website to schedule an appointment for Buick Certified Service. Warranty repairs must be performed at a Buick dealership. Our Certified Service technicians are trained in performing Buick-specific service and repair, and have GM-essential service tools and diagnostics information available to them.

If your vehicle requires warranty repairs during the defined warranty period, alternate transportation and/or reimbursement of certain transportation expenses may be available under the Courtesy Transportation Program.* Several transportation options are available. A loaner vehicle may be an option, but it is best to consult with your dealer for available options.

A vehicle’s wiper blades, brake pads, fluids and tires are just a few of the items that should be maintained on a regular basis. Certified Service experts can recommend your vehicle’s optimum maintenance schedule. Your vehicle Owner’s Manual also is a resource to help you understand your vehicle’s maintenance needs. You can sign in to your GM Account to track your service history, view your vehicle Owner’s Manual, watch how-to videos, check your warranty status and more.
