- Buick vehicles come from the factory with a 48 month/50,000 mile bumper to bumper warranty. The bumper to bumper warranty is known as the vehicle's comprehensive warranty; it guarantees all factory-installed equipment to be free from defect or the defect will be repaired, at no cost to the consumer. Maintenance items such as oil changes or alignments are not covered under the warranty, but defects such as electrical or engine problems are. The warranty coverage begins immediately after the vehicle is initially purchased.
- Buick vehicles come with a 60 month or 100,000 mile powertrain warranty in conjunction with the bumper to bumper warranty. The 60-month term begins when the vehicle is initially purchased, not at the expiration of the bumper to bumper warranty. The powertrain warranty covers all major internal engine, transmission and drive axle components.
- Buick vehicles offer roadside assistance for a term of 60 months or 100,000 miles, whichever comes first. Buick roadside assistance covers emergency towing, lock-out relief, fuel delivery and flat tire changes. The roadside assistance service is available 24 hours a day/seven days a week.
- Buick vehicles are guaranteed to be free from rust and corrosion for 72 months or 100,000 miles. If the vehicle does have rust or corrosion, Buick warranty will pay for the necessary repairs. All body components are protected during this warranty term.
- Buick factory warranty does not protect against damage caused by abuse or neglect, damage from accidents or if the problem is caused by harm from aftermarket components. Aftermarket options installed will not be covered by Buick under any of the warranty terms.
