Keeping your truck in good condition is likely one of your greatest concerns as a GMC Sierra owner. After all, this full-size pickup truck has extensive towing capabilities and costs upwards of $37,000 and higher, which is a big expense. So, wanting to ensure its parts stay working for as long as possible is only natural. By knowing your warranty options and the extra perks you can get to support you and your vehicle during a mechanical breakdown, you can find a plan that suits your needs and budget and prevents high-cost repair bills down the road.
With a new GMC Sierra purchase, you automatically get coverage protection through the manufacturer’s original factory agreement. But once that contract expires, it’s up to you to pay out-of-pocket for any repairs you face unless you invest in another policy. Which extended Sierra GMC warranties will offer you the best protection for your needs and budget? Let’s look!
What Does the Factory GMC Sierra Warranty Offer?
The General Motors Company (GMC) prioritizes your peace of mind and designs its coverage and benefits to protect you from future unplanned mechanical breakdowns. When you buy a Sierra, you gain several standard but limited warranties and extra perks, including, but not limited to:
- A Bumper-to-Bumper Limited Warranty – For the first 3 years or 36,000 miles, you will receive complete vehicle coverage protection to correct any defect in materials or workmanship in your new GMC Sierra, including parts and labor. The coverage also protects against tire defects (excluding normal wear) and towing services to the closest allowed dealership for covered repair work.
- A Powertrain Limited Warranty – As a 5-year or 60,000-mile coverage plan, the Powertrain limited warranty will protect against materials and/or workmanship defects for engine components, transmission/transaxle, and transfer case parts drive systems of your GMC Sierra.
- Roadside Services – Every 2016 or newer GMC passenger car, light-duty truck, and EV model comes with roadside assistance for 5 years/60,000 miles, whichever comes first. EV models also get towing coverage for 8 years/100,000 miles.
- Courtesy Transportation – When your truck needs warranty-covered repair work during your contract period, GMC will provide you with alternative transportation or transportation expense reimbursements when applicable.
Complimentary Maintenance – GMC promises to cover your first service visit during the first year of owning or leasing a new GM vehicle. The routine services include an oil change, multi-point vehicle inspection, and a 4-tire rotation. However, you must take the car to a participating dealer.
Can I Get a GMC Extended Car Warranty?
Before your Sierra’s original policy expires, you can extend your coverage and buy a GMC Protection Plan from your local dealership. GMC offers three vehicle service contracts (VSCs), which include the following options:
The Powertrain Plan – Even though this choice provides the lowest coverage tier, it protects several critical car components—engine, transmission, drive axle, and hybrid/electric—in case of a breakdown.
The Silver Plan – Along with the parts listed in the Powertrain plan, you also receive protection for the front/rear suspension, climate control, electrical, steering, and brakes in this policy.
The Platinum Plan – This contract, available for up to 8 years or 100,000 miles, is the closest plan GMC offers to extended bumper-to-bumper coverage. It covers all vehicle parts besides the ones the terms and conditions explicitly exclude. In addition, the Platinum option includes everything in the Powertrain and Silver plan and many other parts relating to high tech, audio, and navigation.
Do I Get Extra Perks with My GMC Plan?
Besides the protection you get with an extended GMC Sierra warranty from the dealership, you also gain other add-ons like 24/7 roadside help, trip interruption services, rental car coverage, contract transferability, and a 30-day cancellation window. GMC also provides a “disappearing deductible” feature that waives the $100 deductible when you complete repair work with the same GMC dealer that sold you the agreement.
How Much Will a GMC Warranty Cost Me?
How much money you spend on a GMC Sierra warranty depends on your coverage level, where you buy the agreement, and the deductible amount. However, according to Consumer Affairs, Platinum coverage for Sierra 2500HD with 500 miles, which covers 7 years or 70,000 miles, sells for $3,700. A 7-year or 100,000-mile-term contract sells for $4,000. Further research by Consumer Affairs notes that the average extended auto warranty costs roughly $2,500, so the price for a GMC plan is much heftier than those you can get for other motor vehicles.
Is an Extended GMC Sierra Warranty Worth It?
Data from RepairPal shows that the average repair and maintenance costs for a GMC Sierra 1500 are $727 a year. The site also ranks the Sierra with an above-average reliability rating—3.5/5.0. Therefore, investing in extended coverage may benefit you if you can’t afford an unplanned repair bill or want peace of mind when facing future mechanical breakdowns. Still, your option for a vehicle protection plan is not just through the dealerships known to markup warranties to increase their profit margin and force you to use their services for repairs. Other options are available to you.
Can I Get an Auto Warranty Elsewhere?
Several respectable third-party companies like Endurance, Olive, and Everything Breaks offer affordable coverage plans, extra perks, and the option to choose your mechanic. Instead of being restricted to taking your car to the GMC dealership for all recommended maintenance, you can freely select your ASE-certified mechanic to complete the work.
