GMC Roadside Assistance: Towing and Emergency Help

GMC Roadside Assistance helps drivers request towing, battery jump-starts, vehicle lockout service, flat-tire assistance and emergency fuel delivery.

GMC now publishes a dedicated Roadside Assistance number that is different from its general Customer Assistance number. GMC electric vehicles also have a separate toll-free roadside number.

What Does GMC Roadside Assistance Include?

GMC currently lists the following roadside services:

• Towing to the nearest GMC dealer from a legal roadway
• Vehicle unlock service
• Flat-tire changes using the vehicle’s spare tire
• Battery jump-starts
• Emergency fuel delivery
• Telephone assistance from a roadside advisor

Coverage, limits and out-of-pocket charges can depend on:

• The vehicle’s model year
• Current mileage
• Warranty status
• An active OnStar or Connected Services plan
• A separately purchased protection plan
• The cause of the breakdown
• The vehicle’s location
• The type of service requested

Ask the advisor whether the service is covered before authorizing dispatch.

What Information Should You Give the Roadside Advisor?

Have ready:

• Your full name
• A callback telephone number
• The vehicle identification number when available
• Vehicle year, model, color and license plate
• Current mileage
• Your exact location
• Road name and direction of travel
• Nearby exit, mile marker or landmark
• Description of the vehicle problem
• Whether passengers, children or pets are inside
• Whether the vehicle is in a dangerous location
• The preferred GMC dealer when applicable

The myGMC app or an active OnStar connection may provide the vehicle’s location automatically.

When to Call 911 Instead of Roadside Assistance

Call 911 first when:

• Someone is injured.
• The vehicle is blocking an active traffic lane.
• The vehicle is on fire or smoking heavily.
• Fuel is leaking.
• The vehicle is in floodwater.
• You are stranded in a dangerous location.
• You feel threatened by another person.
• A child, vulnerable adult or animal is locked inside in dangerous temperatures.

Roadside Assistance is not a replacement for police, fire or emergency medical services.

If possible, turn on the hazard lights, move away from traffic and remain behind a guardrail or other protected area.

GMC Roadside Assistance Warranty Coverage

GMC currently states that Roadside Assistance is included for:

Five years or 60,000 miles, whichever comes first

on 2016-or-newer GMC:

• Passenger vehicles
• Light-duty trucks
• Electric vehicles

GMC electric vehicles currently receive tow coverage for:

Eight years or 100,000 miles, whichever comes first

Coverage can vary by model, model year and vehicle type. Heavy-duty trucks, commercial vehicles, older GMC vehicles and separately purchased protection plans may have different terms.

Check:

• The vehicle’s warranty booklet
• The owner’s manual
• The GMC account warranty page
• An authorized GMC dealer
• The roadside advisor

How to Check GMC Warranty Status

Sign in to the GMC or GM owner account and review the vehicle’s warranty information.

Have the VIN and current mileage available.

Ask the advisor or dealer to confirm:

• Whether Roadside Assistance remains active
• The expiration date
• The applicable mileage limit
• Whether the requested service is included
• Whether a protection plan provides additional coverage

Do not assume the powertrain warranty and Roadside Assistance expire on the same date.

Can You Use GMC Roadside Assistance After Coverage Expires?

GMC says roadside help can be requested whether the vehicle is under warranty or not.

When coverage has expired, the vehicle owner may be responsible for:

• Towing
• Unlock service
• Fuel
• Battery service
• Additional mileage
• Special recovery equipment

Ask for the estimated charge before dispatch.

Do not assume that merely calling GMC makes an out-of-warranty service free.

GMC Towing Assistance

Covered towing is generally directed to the nearest authorized GMC dealer.

Tell the advisor:

• Whether the vehicle can be shifted into neutral
• Whether the wheels will roll
• Whether it is four-wheel drive or all-wheel drive
• Whether the vehicle is an EV
• Whether a trailer is attached
• Whether the truck has been modified or lifted
• Whether it is in a parking garage
• Whether it is off-road or stuck

These details can affect the equipment required.

Can GMC Tow to a Different Dealer?

Standard covered towing is generally to the nearest GMC dealer.

A vehicle owner who requests:

• A more distant GMC dealer
• An independent repair shop
• A home address
• A body shop

may be responsible for additional charges.

Ask the roadside advisor to explain any mileage or destination charge before the tow begins.

Vehicle Is Not on a Legal Roadway

GMC describes standard towing as being available from a legal roadway.

Additional charges or separate recovery arrangements may apply when the vehicle is:

• Off-road
• On a trail
• In mud or sand
• Below an embankment
• In a restricted parking structure
• In a location inaccessible to a normal tow truck

Explain the location accurately so the correct equipment can be dispatched.

GMC Roadside Assistance for a Flat Tire

GMC’s roadside service installs the vehicle’s usable spare tire.

Before calling, determine whether:

• The vehicle has a spare tire.
• The spare is inflated.
• The wheel-lock key is present.
• The jack and tire tools are available.
• The vehicle has more than one damaged tire.
• The vehicle is in a safe location.

Some newer vehicles and EVs may not include a traditional spare tire.

If no usable spare is available, towing may be required.

Does GMC Roadside Assistance Repair the Tire?

Standard roadside service generally changes the damaged tire using the vehicle’s spare. It does not normally perform a permanent tire repair on the roadside.

After installing a temporary spare:

• Follow the spare tire’s speed restriction.
• Follow its distance limitation.
• Visit a tire or GMC service facility promptly.
• Do not tow a trailer unless the vehicle manufacturer permits it.

GMC Battery Jump-Start Assistance

Call roadside assistance when the vehicle will not start and a discharged 12-volt battery is suspected.

Tell the advisor:

• Whether lights or accessories work
• Whether the engine clicks or cranks
• Whether a battery warning appeared
• Whether the battery was recently replaced
• Whether the vehicle is an EV
• Whether the vehicle is parked in a garage

A successful jump-start does not prove that the battery is healthy.

Have the battery and charging system tested when the problem returns.

Repeated Dead GMC Battery

Possible causes include:

• An aging battery
• A charging-system problem
• An electrical draw
• A module that does not shut down
• Aftermarket equipment
• A loose or corroded connection
• Extended vehicle storage

Schedule dealer diagnosis when repeated jump-starts are needed.

Save each roadside case number and date because the pattern may help document an unresolved warranty concern.

GMC Vehicle Lockout Service

GMC Roadside Assistance may dispatch a provider to unlock the vehicle.

The vehicle owner may need to show:

• Photo identification
• Vehicle registration
• Proof of ownership or authorized use

GMC states that the cost of a replacement key and the labor required to create a new key are not included in roadside unlock coverage.

Try Remote Unlock First

An eligible vehicle with an active connected-services plan may support remote unlocking through:

• The myGMC app
• An OnStar Advisor
• The vehicle owner account

Remote features require compatible equipment, an eligible plan and account access.

Do not leave a child or animal inside while waiting for ordinary roadside service when temperatures or other conditions are dangerous. Call emergency services immediately.

GMC Emergency Fuel Delivery

Roadside Assistance may arrange emergency fuel delivery for a gas or diesel vehicle.

Ask:

• How much fuel will be delivered
• Whether the fuel itself is covered
• Whether a service charge applies
• Whether diesel fuel is available
• How long the provider should take

Provide the correct fuel type.

Putting gasoline into a diesel GMC or diesel fuel into a gasoline vehicle can cause significant damage.

Do not start the vehicle if the wrong fuel was added. Request towing to an authorized service facility.

GMC EV Roadside Assistance

Call the dedicated EV line:

1-844-515-1418

GMC currently states that EV tow coverage is included for eight years or 100,000 miles, whichever comes first.

Tell the advisor:

• The GMC EV model
• The remaining charge level
• Any warning messages
• Whether the vehicle can be shifted into neutral
• Whether the 12-volt system is operating
• Whether the high-voltage battery appears damaged
• Whether the vehicle is connected to a charger
• The nearest accessible charging location

Electric GMC vehicles can require specific towing and loading procedures. Do not allow an unqualified provider to tow the vehicle with drive wheels improperly contacting the road.

GMC EV Ran Out of Charge

Call the EV roadside number and explain that the high-voltage battery is depleted.

The vehicle may need to be transported to:

• A compatible charging location
• An authorized GMC EV dealer
• Another destination approved by the roadside program

Confirm the towing destination and any cost before dispatch.

EV Charging Station Problem

A charging problem may involve:

• The vehicle
• The charging cable
• The home charger
• The public charging station
• The charging-network account
• Payment authorization

Record:

• The charging-network name
• Station number
• Error message
• Time and location
• Battery percentage
• Photographs of the charger display

Contact the charging-network operator when the station itself is malfunctioning.

Requesting Roadside Assistance Through OnStar

Drivers with an eligible active OnStar or Connected Services plan may request roadside assistance by:

• Pushing the blue OnStar button
• Using the myGMC app
• Selecting Roadside Assistance through the vehicle infotainment system when equipped
• Calling 1-888-466-7827

OnStar can use connected-vehicle information to help determine the vehicle’s location and condition.

Drivers without an active OnStar or Connected Services plan should call GMC Roadside Assistance directly at 1-888-881-3302.

OnStar Plan Is Not Active

Roadside assistance may still be requested by telephone.

However, the driver may not have access to:

• Automatic location transmission
• In-vehicle advisor contact
• Remote app features
• Roadside benefits included with a paid OnStar plan

Confirm whether vehicle warranty coverage applies and whether charges are expected.

GMC Roadside Provider Is Late or Did Not Arrive

Wait times depend on:

• Location
• Weather
• Traffic
• Provider availability
• Required equipment
• Whether the location is safe and accessible

If the provider is late:

1. Call the roadside number again.
2. Provide the existing case or dispatch number.
3. Confirm that your location and telephone number are correct.
4. Ask whether a provider accepted the request.
5. Request the provider’s name and estimated arrival time.
6. Ask for reassignment when the provider cannot respond.

Do not open several unrelated service requests for the same breakdown unless the advisor instructs you to do so.

Roadside Provider Canceled the Request

Ask GMC to confirm:

• Why the dispatch was canceled
• Whether another provider is being assigned
• Whether the location is outside standard service conditions
• Whether additional equipment is needed
• Whether any customer payment is required

Save text messages, app screenshots and the service-request number.

Unexpected Roadside Assistance Charge

Before paying a roadside provider, ask:

• Which service is not covered
• Whether the charge is for extra towing mileage
• Whether special recovery equipment is required
• Whether the vehicle’s coverage expired
• Whether the destination differs from the nearest dealer
• Whether fuel or replacement parts are being purchased

Request a written receipt showing:

• The provider’s name
• The service performed
• The vehicle information
• The date and location
• The amount paid

Contact GMC before paying an unexpected charge when it is safe and practical to do so.

Roadside Assistance Versus GMC Warranty Towing

Roadside Assistance can address common roadside situations, while warranty towing applies when a vehicle cannot be driven because of a potentially covered defect.

A dealer must diagnose the vehicle to determine whether the repair is covered by warranty.

Keep:

• The roadside case number
• The tow receipt
• The dealer repair order
• The diagnosis
• All communication with GMC

If a dealer determines the repair is not covered, diagnosis, towing or repair charges may become the owner’s responsibility.

How to Escalate a GMC Roadside Assistance Complaint

1. Contact Roadside Assistance again. Reference the original dispatch or case number.
2. Document the problem. Save texts, arrival estimates, provider names, receipts and photographs.
3. Request a roadside supervisor. Explain whether the issue involves delay, cancellation, damage, towing destination or an unexpected charge.
4. Contact GMC Customer Assistance. Call 1-800-462-8782.
5. Ask for a GMC case number. Record the representative and promised action.
6. Contact the servicing dealer. Do this when the breakdown or tow involves a warranty repair.
7. Submit a written complaint. Include the roadside and dealer case numbers.
8. Report provider-caused vehicle damage promptly. Photograph it before the vehicle is repaired or moved again.
