Buick and GMC Services

Brakes
Pads, rotors and calipers will need to be repaired or replaced as part of regular brake service. Brake pad life depends on driving habits, vehicle usage and operating environment. Buick and GMC vehicle’s brakes will alert you when there’s trouble. Whistling noises, chirping sounds, and grinding are indications that brake service is required. Here are some common causes of brake pedal pulsation and/or noise:
- Worn brake pads
- Heat-cracked or worn rotors
- Loose-fitting brake pads in the caliper
- Missing or damaged noise insulators
- Uneven torque of lug nuts or caliper hardware

Oil Change
For routine oil changes, consult your Buick or GMC Owner’s Manual to find the recommended oil change intervals for your specific vehicle. Many Buick and GMC models feature an advanced Engine Oil Life System (OLS), designed to take the guesswork out of maintenance. This intelligent system tracks your vehicle’s speed, engine temperature, and operating conditions to determine precisely when an oil change is needed. It even adapts to your driving habits and local climate, ensuring that oil changes are timed perfectly. The OLS not only simplifies vehicle maintenance but also helps save money and reduce oil waste, making it a smart and sustainable solution.

Engine/Transmission
The engine and transmission are the core of your Buick or GMC, delivering the power that drives your vehicle forward. When it comes to repairs or replacement parts, trust our GM Certified Service professionals to provide Genuine Buick and GMC parts designed for optimal performance and reliability.

Extreme winter cold and scorching summer heat can take a toll on your car's battery over time. That’s why it’s a smart move to visit our service center for a quick battery inspection. If a replacement is needed, our experts will help you find the perfect battery for your vehicle.
