GMC Truck Warranty: Three Different Coverages, and the Fine Print That Separates Them

All New Vehicles

Ask three people about a GMC truck warranty and you will get three answers, because the phrase covers three genuinely different things: the factory coverage that comes with a new Sierra or Canyon, the optional protection plan you can add on top of it, and the limited warranty attached to a used truck. They overlap in name and almost nowhere else. Knowing which one you are actually holding decides what a repair costs you three years from now — and, less obviously, what your truck is worth when you sell it. Linus Buick GMC sits at 1401 US-1, Vero Beach, FL 32960, and you can see what is currently on the lot under All Vehicles.

What the Factory GMC Truck Warranty Actually Covers

Every new GMC arrives with two separate coverages running at once. The Bumper-to-Bumper New Vehicle Limited Warranty runs 3 years or 36,000 miles, whichever comes first, covering the complete vehicle — including tires and towing to your nearest GMC dealer. Underneath it, the Powertrain Limited Warranty runs longer at 5 years or 60,000 miles, covering the expensive core of engine, transmission and drive systems, with Roadside Assistance and Courtesy Transportation on that same 5-year/60,000-mile term. Rust-through corrosion is covered separately for 6 years or 100,000 miles. One exception matters more than any other on a truck lot: every 2016-and-newer Sierra HD 2500 or 3500 fitted with the 6.6L Duramax Turbo-Diesel carries a 5-year/100,000-mile Powertrain Limited Warranty and 5-year/100,000-mile Roadside Assistance instead — 40,000 miles of coverage a gasoline Sierra does not get. That gap belongs in any diesel-versus-gas comparison.

When an Extended Protection Plan Earns Its Place

Once the factory clock runs out, the GM Extended Protection Plan is the mechanism for keeping coverage in place. Endorsed by GMC and backed by General Motors, it comes in three tiers: Powertrain, Silver and Platinum. Silver adds suspension, climate control, electrical, steering and brakes on top of powertrain components. Platinum is the broadest, extending up to 8 years or 100,000 miles and covering up to 1,500 parts and components depending on the plan you choose. It carries Trip Interruption up to $200 per day for five days and rental car coverage at $40 per day for ten days, and is fully refundable within 30 days if you file no claims.

GMC Truck Warranty Transfers: the Fine Print on Resale

This is where the two coverages diverge, and it matters most when you sell. The Powertrain Limited Warranty is fully transferable with no fees and no deductibles, so whatever remains of that 5-year/60,000-mile term follows the truck to its next owner at no cost to either party. That is a real asset, worth stating in a private-sale listing. The extended plan does not behave the same way: private-party transfers are allowed within 30 days of resale or lease assumption and carry a $50 transfer fee, and a transfer to a dealership is not allowed at all. Neither rule is a problem once you know it — but a seller who assumes both work identically can lose the plan’s value by missing that 30-day window.

Used Trucks and the Coverage That Comes With Them

A used truck follows different rules again. Vehicles labeled CarBravo carry a 12-month/12,000-mile Bumper-to-Bumper Limited Warranty that is in addition to any remaining original factory warranty, beginning when that factory coverage expires — so the two stack rather than replace one another. Vehicles labeled BravoBudget carry a 30-day/1,000-mile Powertrain Limited Warranty instead, which is a very different promise, so always confirm which label a specific truck wears. CarBravo also brings a 10-day/500-mile vehicle exchange program, 24-hour roadside assistance, courtesy transportation and access to more than 3,800 Certified Service Centers nationwide.

Frequently Asked Questions

How long is the factory GMC truck warranty?

Two coverages run at the same time. The Bumper-to-Bumper New Vehicle Limited Warranty lasts 3 years or 36,000 miles, whichever comes first. The Powertrain Limited Warranty lasts 5 years or 60,000 miles, covering the engine, transmission and drive systems, and Roadside Assistance and Courtesy Transportation run on that same term. Rust-through corrosion is covered for 6 years or 100,000 miles. Note the diesel exception: a 2016-or-newer Sierra HD 2500 or 3500 with the 6.6L Duramax Turbo-Diesel gets 5 years or 100,000 miles of powertrain coverage and roadside assistance instead.

Does the GMC powertrain warranty transfer to a new owner?

Yes. The Powertrain Limited Warranty is fully transferable with no fees and no deductibles, so any remaining coverage follows the truck to its next owner at no cost. That makes it worth mentioning in a private-sale listing. The GM Extended Protection Plan works differently — private-party transfers are allowed within 30 days of resale and carry a $50 transfer fee, and transfers to a dealership are not permitted.

How long can an extended protection plan cover a GMC truck?

The GM Extended Protection Plan is offered in Powertrain, Silver and Platinum tiers. Platinum extends up to 8 years or 100,000 miles and covers up to 1,500 parts and components depending on the plan selected. It includes Trip Interruption up to $200 per day for a maximum of five days and rental car coverage at $40 per day for up to ten days, and it is fully refundable within 30 days if no claims have been filed.

What warranty comes with a used GMC truck?

It depends on the label. A CarBravo vehicle carries a 12-month/12,000-mile Bumper-to-Bumper Limited Warranty that is in addition to any remaining factory coverage and starts when that coverage ends. A BravoBudget vehicle carries a 30-day/1,000-mile Powertrain Limited Warranty. Confirm which applies to the specific truck before you buy — call (772) 217-5049 and the team will check it for you.
