Buick Customer Care: An Expert Owner’s Guide

How to reach Buick Customer Care quickly

You’ll find the most up-to-date contact options on Buick’s official Support Center at https://www.buick.com/support. From there, owners can access live chat, open a support case, schedule service with a preferred dealer, and review warranty and recall information tied to their VIN. For account-based help (owner profile, connected services, remote commands), use the myBuick mobile app on iOS/Android and the owner portal linked from the Support site.

If your vehicle is equipped with OnStar, press the blue OnStar button in the vehicle for immediate connection to an advisor who can assist with emergencies, remote diagnostics, and roadside requests. When you’re away from the vehicle, you can also call OnStar at 1-888-4-ONSTAR (1-888-466-7827). For dealer-based service needs, use Buick’s dealer locator at https://www.buick.com/dealers to find addresses, hours, and online service schedulers near you.

Warranty coverage: what to expect by model year

Buick warranty terms vary by model year and market. Depending on when your Buick was first placed in service, bumper-to-bumper coverage may be 3 years/36,000 miles or 4 years/50,000 miles, while powertrain coverage on many model years has ranged from 5 years/60,000 miles to 6 years/70,000 miles. Always verify your exact terms in the Warranty and Owner Assistance Information booklet supplied with your vehicle or in your owner portal, because goodwill policies, special coverage adjustments, and service campaigns can extend coverage for specific components.

Federal Emissions Warranty coverage is standardized: major emissions components such as the catalytic converter and engine control module are covered for 8 years/80,000 miles in the United States, regardless of the general bumper-to-bumper term. States that follow California emissions regulations may provide additional protection for certain components; your warranty booklet specifies the parts and durations for your vehicle and registration state.

Recalls, service campaigns, and over-the-air updates

To check for open recalls or special coverage on your Buick, run your 17-character VIN at https://www.nhtsa.gov/recalls or at Buick’s recall lookup within https://www.buick.com/support. Recalls are safety-related and performed at no charge; “Special Coverages” and “Customer Satisfaction Programs” address known issues that may not be safety-related and often have time/mileage limits—review their expiration dates carefully.

Many late-model Buicks can receive software and calibration updates at the dealer, and some systems update over the air. If you’re experiencing intermittent infotainment, Bluetooth, camera, or driver-assistance glitches, ask your service advisor to check for the latest software bulletins and programming updates for your VIN. Keeping your myBuick app updated and allowing the vehicle to complete scheduled updates (when prompted) can reduce visits for software concerns.

Roadside assistance and towing

Roadside assistance provisions can differ by model year; new vehicles typically include roadside coverage that parallels or extends beyond the powertrain term. Coverage usually includes towing to the nearest Buick dealer, battery jump-starts, lockout assistance, fuel delivery, and flat-tire service. Confirm eligibility and limits in your warranty booklet or owner portal.

The fastest way to request help is through OnStar—press the blue button or call 1-888-466-7827. If OnStar is not active, your Buick dealer can still arrange a tow to their service department. Keep your VIN, current location, and preferred dealer name ready to accelerate dispatch.

What to prepare before contacting Customer Care

Arriving prepared shortens resolution time and reduces back-and-forth. Gather documentation and details that allow a Buick advisor or dealer to verify symptoms, timelines, and prior work. If you’re escalating a recurring issue, be specific about dates and outcomes—this is crucial for warranty coverage determinations and for any future arbitration.

• VIN (17 characters) and current odometer reading; ownership name and phone number exactly as on file.
• Concern summary with dates and mileage when symptoms occur; note frequency and conditions (cold start, highway speeds, rain, etc.).
• All repair orders and invoices, including those from independent shops; include RO numbers, dealer names, and dates.
• Diagnostic trouble codes (if available), photos/videos of the issue, and any warning messages displayed.
• Maintenance history (oil changes, coolant/brake fluid service, tires) and proof of intervals—especially if coverage could be affected.
• Recall or campaign IDs (if shown in your owner portal or on NHTSA) and any TSB numbers referenced by your dealer.
• Preferred dealer and your availability windows for drop-off, loaner needs, and authorizations.

Escalation paths, dispute resolution, and safety complaints

Start with your servicing dealer’s Service Advisor and escalate to the Service Manager or the dealership’s General Manager if the concern persists. Ask the dealer to open a case with Buick Customer Care after the first unsuccessful repair attempt or if parts are on extended backorder. When a case number is created, request an estimated timeline, next steps, and the name/extension of your case specialist for direct follow-up.

General Motors (Buick) participates in BBB AUTO LINE for dispute resolution in many states. If you cannot reach a satisfactory resolution with the dealer and Buick Customer Care, contact BBB AUTO LINE at 1-800-955-5100 or visit https://www.bbb.org/autoline to file a claim; you’ll need your VIN, repair orders, and case history. For safety-related defects (stalling, fire risk, airbag, braking, steering), file a complaint with the National Highway Traffic Safety Administration (NHTSA) at https://www.nhtsa.gov/report-a-safety-problem or call the Vehicle Safety Hotline at 1-888-327-4236. NHTSA complaints help trigger investigations and recalls.

State lemon laws vary. As examples: California’s “Song-Beverly” law presumes a vehicle is a lemon if, within 18 months or 18,000 miles, it has a substantial defect not repaired after a reasonable number of attempts; Florida’s law defines a 24-month “rights period.” Check your state attorney general’s website for exact criteria, required written notices, and timelines before seeking repurchase or replacement, and continue working with Buick Customer Care while you gather documentation.

Certified Pre-Owned (CPO) and out-of-warranty assistance

GM Certified Pre-Owned Buicks typically include a 6-year/100,000-mile limited powertrain warranty from the original in-service date and a 12-month/12,000-mile bumper-to-bumper limited warranty from the CPO delivery date, both with $0 deductible. Program benefits also often include courtesy maintenance, roadside assistance, and a 3-day/150-mile vehicle exchange policy. Verify your CPO contract for exact coverages and start/end dates.

If your vehicle is out of warranty, ask your dealer and Buick Customer Care whether a Special Coverage Adjustment applies, or whether goodwill participation is possible when there’s strong maintenance history and a known early component failure. Technical Service Bulletins (TSBs) can guide accurate diagnosis even when repairs are customer-pay; request that your advisor check for the latest TSBs by VIN before authorizing major work.

Digital tools: myBuick app and owner resources

The myBuick app consolidates connected services, maintenance records, and service scheduling. With an active subscription, you can remotely lock/unlock and start the vehicle, check fuel and tire pressures, and receive health alerts. Even without a paid plan, you can store your VIN, access the owner’s manual and how-to videos, and receive recall notifications. Keep the app updated to ensure compatibility with the latest vehicle software.
