When you drive a new vehicle home from Central Chevrolet in West Springfield, MA, it comes backed by a collection of distinct factory warranties from General Motors (GM). Rather than a single blanket policy, your vehicle is covered by several individual warranties that protect different components based on how they function.
To help you understand exactly how your ride is protected, here is a straightforward breakdown of each factory warranty and what it means for your vehicle.
The Bumper-to-Bumper Limited Warranty
- Standard Coverage: 3 Years or 36,000 Miles (whichever comes first)
- Deductible: $0
This is your baseline new-vehicle protection. It covers repairs, including both parts and labor, to correct any factory defect in materials or workmanship for almost every component on the vehicle.
- What it covers: Interior electronics, touchscreens, climate control units, power window motors, lighting assemblies, and suspension components.
- Added perks: It includes warranty protection on your original factory tires against manufacturing defects (excluding normal wear) and covers complimentary towing to the nearest authorized Chevrolet dealership if a warrantable issue leaves you stranded.
The Powertrain Limited Warranty
- Standard Coverage: 5 Years or 60,000 Miles (whichever comes first)
- Duramax® Diesel Coverage: 5 Years or 100,000 Miles (whichever comes first)
The Powertrain warranty takes over where the bumper-to-bumper coverage ends, focusing specifically on the heavy, mechanical systems that generate and deliver power to move the vehicle.
- What it covers: The engine block, cylinder heads, oil pumps, timing gears, valvetrain, internal electrical components, oil pans, the transmission case, torque converters, transfer cases, and drive axle assemblies.
- The Diesel Upgrade: For heavy-duty trucks equipped with a 3.0L or 6.6L Duramax® Turbo-Diesel engine, GM extends this coverage to 100,000 miles to accommodate the heavy-duty workloads these trucks endure. This version explicitly covers diesel-specific components like fuel injection pumps, injectors, glow plugs, and turbochargers.
The EV Propulsion Battery Warranty
- Standard Coverage: 8 Years or 100,000 Miles (whichever comes first)
Electric vehicles do not have traditional mechanical engines or transmissions, meaning they do not carry a conventional "powertrain" warranty. Instead, GM implements a highly specialized Electric Vehicle Propulsion Warranty.
- What it covers: The high-voltage battery pack, internal battery cells, thermal management systems, onboard charging modules, and the electric drive motors that spin the wheels.
- Battery Degradation Protection: Because electric vehicle batteries naturally lose a minor amount of energy capacity over years of charging cycles, this warranty specifically outlines protection against abnormal, severe capacity loss to ensure your driving range remains stable.
- Extended Towing: Roadside towing to an EV-certified dealer is extended to match the full 8-year or 100,000-mile duration of the battery.
Corrosion & Rust-Through Protection
- Corrosion Coverage: 3 Years or 36,000 Miles
- Rust-Through Perforation: 6 Years or 100,000 Miles
Designed to handle external environmental factors like road salt and moisture, this protection is split into two categories. Standard corrosion covers surface rust on body panels. Rust-Through protection specifically covers you if rust completely eats a physical hole through a sheet metal panel from the inside out.
