Buick Roadside Assistance provides 24-hour help for eligible Buick vehicles experiencing a breakdown, flat tire, dead battery, lockout, fuel shortage, accident, or towing need. Coverage, towing destinations, customer-paid costs, and available services depend on the vehicle, model year, warranty status, location, and circumstances.

Emergency warning: Call 911 or the appropriate local emergency service first if anyone is injured, the vehicle is on fire, the vehicle is blocking traffic, or the location presents an immediate danger. Roadside Assistance is not a substitute for police, fire, highway-patrol, or emergency medical services.

Is Buick Roadside Assistance Available 24 Hours?

Yes. Buick identifies Roadside Assistance as available 24 hours a day, seven days a week, 365 days a year.

Buick Customer Assistance is a separate non-emergency support channel. Its current published telephone hours are:

Monday–Saturday: 8:00 a.m.–9:00 p.m. Eastern Time
Sunday: Closed

Buick’s online support-request form is intended for non-emergency assistance. Buick says an advisor generally responds to a support request within one business day.

How to Request Buick Roadside Assistance

You may be able to request help through:

The U.S. Roadside Assistance number at 1-800-252-1112
The myBuick mobile app
An eligible vehicle’s infotainment system
The blue OnStar button when the vehicle has an applicable OnStar or connected-services plan

Owners without an active OnStar or connected-services plan should call Buick Roadside Assistance directly.

Information to Have Ready When Calling Buick

Your name and safe callback number
The vehicle identification number, or VIN
Buick model, model year, color, and license plate
Current odometer reading
The vehicle’s exact location
Road name, direction of travel, exit, mile marker, cross street, or nearby landmark

A description of the problem
Whether the vehicle is in an unsafe location
Whether the Buick has a usable spare tire
Whether anything is attached to or being towed by the vehicle
The preferred Buick dealer when towing may be required

Tell the advisor immediately when the vehicle is stopped in a travel lane, on a narrow shoulder, near moving traffic, or in another dangerous location.

What Services Does Buick Roadside Assistance Provide?

Depending on eligibility, vehicle equipment, location, and the nature of the disablement, Buick Roadside Assistance may provide or coordinate:

Towing from a legal public roadway
Flat-tire changes using the vehicle’s spare tire
Battery jump-start service
Vehicle lockout assistance
Emergency fuel delivery
Towing after a crash when the vehicle cannot be driven
Trip-interruption assistance following an eligible warranty event

Availability does not mean that every part, tire, key, repair, gallon of fuel, towing destination, or roadside expense is included. Ask whether the requested service is covered before authorizing additional work or agreeing to a charge.

How Long Is Buick Roadside Assistance Included?

Buick currently states that Roadside Assistance is included for five years or 60,000 miles, whichever occurs first, on 2020-or-newer Buick passenger vehicles.

Coverage generally follows the applicable powertrain-warranty period, but the exact expiration date can depend on the vehicle’s model year, original in-service date, mileage, purchase history, and applicable program.

Confirm the vehicle’s current status through:

The Buick warranty tracker in the owner account
The myBuick app
The vehicle’s Owner’s Manual and warranty booklet
An authorized Buick dealer
Buick Roadside Assistance using the VIN

A vehicle outside the included coverage period may still be able to request dispatch, but the owner may be responsible for the service charge.

Is Roadside Assistance Part of the Vehicle Warranty?

Buick describes Roadside Assistance as a separate customer-support program rather than part of the New Vehicle Limited Warranty. A tow may be eligible even when the resulting tire, battery, key, collision damage, or mechanical repair is not covered by the vehicle warranty.

Who Can Use Buick Roadside Assistance?

For an eligible U.S. vehicle, Roadside Assistance generally follows the covered Buick rather than applying only when the registered owner is driving.

The driver should be authorized to use the vehicle and may need to provide identification, vehicle information, and proof of access before lockout or other security-sensitive service is provided.

Buick Roadside Assistance Versus OnStar

Buick Roadside Assistance and OnStar are related but separate support routes.

Use Buick Roadside Assistance For

A tow
A flat tire
A dead battery
A vehicle lockout
Emergency fuel delivery
A disabled Buick
An active roadside dispatch problem

Use OnStar For

OnStar plan and subscription questions
OnStar billing or cancellation
The OnStar Guardian app
Connected-services problems
Remote vehicle commands
Automatic Crash Response questions
Stolen Vehicle Assistance
Roadside requests included in an applicable OnStar plan

Call OnStar at 1-888-466-7827 for plan, account, billing, or connected-services support. Press the blue OnStar button in an equipped vehicle when that option is available and safe to use.

What to Do If Buick Roadside Assistance Does Not Arrive

If the estimated arrival time passes and the assigned provider has not contacted you:

Call 1-800-252-1112 again.
Provide the existing roadside case or dispatch number.
Ask whether the provider accepted the assignment.
Request the provider’s name and updated estimated arrival time.
Ask whether the dispatch can be reassigned when the provider cannot respond.

Repeat that the vehicle is in an unsafe location when applicable.
Record the time of every call, ETA, provider name, and response.

Call police, highway patrol, or emergency services when the disabled vehicle presents a traffic hazard or the occupants cannot remain safely at the location.

How to File a Buick Roadside Assistance Complaint

While the roadside request remains active, call 1-800-252-1112 and ask the advisor to review or escalate the dispatch.

After the immediate incident, use:

Buick Customer Assistance: 1-800-521-7300
Online support request: Buick Contact Us
Dealership management: For an unresolved repair, warranty, vehicle-condition, or dealership problem
Customer Assistance mailing address: Buick Customer Assistance Center, P.O. Box 33172, Detroit, MI 48232-5172

Buick does not currently publish a dedicated general complaint or Roadside Assistance email address. Do not rely on an email address found only on an unofficial directory or social-media post.

Information to Include in a Roadside Complaint

Vehicle year, model, and mileage
A partial VIN for ordinary unsecured correspondence
Date, time, and general location of the incident
Roadside case or dispatch number
The service requested
The assigned towing or roadside provider
The original and revised arrival estimates
Actual arrival time or provider no-show
The towing destination
Any amount requested or paid
Photographs, receipts, and relevant messages
A chronological description of what occurred
The resolution requested

How to Escalate an Unresolved Complaint

Ask the Roadside Assistance advisor to review the active case.
Request a supervisor when the assigned provider is not responding or the dispatch information is incorrect.

Keep the roadside case number and provider details.
Open a Buick Customer Assistance case after the immediate incident.
Ask for the Buick case number and expected follow-up date.
Contact the dealership’s service manager or general manager when a warranty repair is involved.

Submit receipts, photographs, and prior correspondence.
Ask for a written explanation when coverage or reimbursement is denied.
Review the vehicle-specific warranty booklet before challenging a warranty decision.

A formal warranty dispute may qualify for the dispute-resolution procedure described in the applicable Buick warranty materials. A roadside provider delay by itself is not necessarily a vehicle-warranty dispute.

Where Will Buick Tow the Vehicle?

Covered emergency towing generally transports the vehicle from a legal public roadway to the nearest authorized Buick or appropriate GM dealer for warranty service. Towing may also be arranged after a crash when the Buick cannot be driven.

Before the tow begins, confirm:

The dealer name and address
Whether the dealer can accept the vehicle
Whether the service department is open
Where the keys will be left after hours
Whether the requested destination is covered
Whether any additional mileage or storage charge applies

A roadside tow does not guarantee immediate diagnosis, a same-day repair, warranty approval, a loaner vehicle, or parts availability.

Can You Choose a Different Repair Shop?

A customer-selected dealer or independent repair facility may not be included. Ask the advisor whether the alternative destination is permitted and whether the owner must pay an additional towing charge.

Buick Flat-Tire Assistance

Buick may provide a flat-tire change when the vehicle has a usable spare tire.

Tell the advisor:

Which tire is affected
Whether a spare tire is present
Whether the spare is properly inflated
Whether the wheel or suspension appears damaged
Whether locking wheel nuts or special equipment are involved
Whether the vehicle is stopped near moving traffic

The owner remains responsible for repair or replacement of the damaged tire unless another warranty or tire-protection agreement applies.

When the vehicle has no usable spare, ask whether towing to the nearest authorized dealer is available. Roadside Assistance does not promise mobile delivery of a replacement tire.

Buick Battery Jump-Start Assistance

Roadside Assistance may dispatch a provider to jump-start a discharged 12-volt battery.

Tell the advisor when:

The battery is leaking, swollen, overheated, or visibly damaged
There is smoke, fire, or a strong unusual odor
The Buick repeatedly loses power after being started
The dashboard displays an electrical-system warning
The vehicle is a hybrid or electric model

Do not touch exposed or damaged high-voltage components. Contact emergency services when there is smoke, fire, leaking fluid, or another immediate electrical danger.

A jump-start service does not automatically include battery replacement, diagnosis, or repair.

Buick Lockout Assistance

Roadside Assistance may help unlock the vehicle. A remote unlock may also be available through an eligible OnStar or connected-services plan.

For security reasons, the driver may need to present identification and show authorization to access the vehicle.

Lockout service does not automatically cover:

A replacement key
A replacement key fob
Key programming
Broken-key extraction
Repair of damaged locks
Transportation to retrieve another key

Call emergency services immediately when a child, vulnerable person, or animal is locked inside and faces danger.

Buick Emergency Fuel Delivery

Emergency fuel delivery may provide enough fuel for the Buick to reach the nearest service station.

Before service is dispatched, confirm:

The required fuel type
Whether the vehicle is gasoline, diesel, hybrid, or electric
Whether the fuel itself is customer-paid
Whether the vehicle displays another mechanical warning

Emergency fuel delivery is not intended to provide a full tank. Do not attempt to add an incorrect fuel or operating fluid.

What to Do After a Buick Accident

Call emergency services when anyone is injured or the scene is unsafe.

Move away from traffic when it can be done safely and lawfully.
Contact police when required.
Call Buick Roadside Assistance at 1-800-252-1112 when the vehicle cannot be driven.
Photograph the vehicles, damage, road conditions, and surrounding area when safe.

Collect appropriate information from the other involved parties.
Keep the police-report or incident number.
Notify the automobile insurer when the incident may be a covered claim.

Do not assume that Buick Roadside Assistance pays for collision repairs, insurance deductibles, impound fees, storage, rental transportation, property damage, or every accident-related tow.

Buick Trip-Interruption Assistance

If a trip is interrupted by a qualifying warranty event during the applicable coverage period, certain incidental expenses may be considered for reimbursement.

Potentially considered expenses may include:

Reasonable hotel costs
Meals
A rental vehicle
Delivery of the repaired vehicle back to the customer, potentially up to the program’s distance limit

Eligibility and reimbursement are not automatic. Contact Buick Roadside Assistance at the time of disablement, ask whether the incident qualifies, follow the advisor’s instructions, and retain original detailed receipts and repair records.

Can You Arrange Your Own Tow?

Call Buick Roadside Assistance before hiring a towing company whenever official dispatch is available. Self-arranged service does not guarantee reimbursement.

If immediate circumstances require an independent provider:

Use a properly licensed and insured towing company.
Confirm that the equipment is appropriate for the Buick.
Obtain an itemized original receipt.
Keep proof of payment.
Record the pickup and destination locations.
Record the tow mileage.
Document why the official dispatch could not be used.
Contact Buick promptly and request written reimbursement instructions.

Do not assume that Buick will repay the full amount.

Services and Expenses Buick Roadside Assistance May Not Cover

Program terms can exclude or limit:

Impound towing resulting from a violation of law
Legal fines
Police-mandated towing reimbursement
Mounting or removing snow tires
Installing or removing snow chains and traction devices
Towing a boat, camper, trailer, cargo box, or other item attached to the vehicle
Off-road recovery
Vehicles stuck in sand, mud, or snow
Service on inaccessible or unmaintained roads
Service on certain restricted roads, tunnels, toll roads, or bridges

A replacement tire or wheel
Replacement keys and programming
Fuel, parts, fluids, or repairs
A customer-selected towing destination
Services outside the applicable coverage period

Buick and General Motors may also limit service or payment when claims are made unusually often or the same type of claim is repeatedly submitted.

Buick Factory Roadside Assistance Versus Other Plans

Several different products may provide roadside benefits:

Factory-included Buick Roadside Assistance
An active OnStar plan
A Buick Protection Plan
Tire and Wheel Protection
A certified-used vehicle program
An automobile insurance policy
A credit-card or membership roadside benefit

These programs may use different dispatch numbers, per-occurrence limits, service-event limits, reimbursement rules, administrators, and exclusions. Review the agreement that applies to the vehicle rather than assuming every roadside benefit uses Buick’s factory terms.

Buick Roadside Assistance Scam Warning

Fraudsters and misleading advertisements may display unofficial Buick roadside numbers or impersonate Buick, General Motors, OnStar, a dealership, or a towing provider.

Use 1-800-252-1112 for U.S. Buick Roadside Assistance.
Do not provide account passwords or one-time verification codes to an unsolicited caller.
Do not pay with gift cards or cryptocurrency.
Confirm the towing company assigned to the official case.
Ask for an itemized receipt for any customer-paid amount.
