2014 GMC Sierra 3500 Reviews

Vehicle Overview

Sharing much the same underpinnings with the Chevrolet Silverado HD pickup truck, the GMC Sierra HD provides truck buyers with a bit more style and luxury — especially in Denali trim. Its light-duty sibling, the 1500, was completely redesigned for 2014, but the heavy-duty 2500HD and 3500HD variants carry on. Updated versions are expected early in 2014 as 2015 models.
New for 2014
Gas trucks now have a standard 4.10 axle ratio; a 3.73 ratio is available. A spray-on bedliner is available and a bi-fuel version of the 2500HD crew cab can run on gasoline or compressed natural gas.

Warranties Explained

Bumper-to-Bumper

Often called a basic warranty or new-vehicle warranty, a bumper-to-bumper policy covers components like air conditioning, audio systems, vehicle sensors, fuel systems and major electrical components. Most policies exclude regular maintenance like fluid top offs and oil changes, but a few brands have separate free-maintenance provisions, and those that do offer them is slowly rising. Bumper-to-bumper warranties typically expire faster than powertrain warranties.

Powertrain

Don't be misled a 10-year or 100,000-mile powertrain warranty doesn't promise a decade of free repairs for your car. It typically covers just the engine and transmission, along with any other moving parts that lead to the wheels, like the driveshaft and constant velocity joints. Some automakers also bundle seat belts and airbags into their powertrain warranties. With a few exceptions, powertrain warranties don't cover regular maintenance like engine tuneups and tire rotations.

Roadside Assistance

Some automakers include roadside assistance with their bumper-to-bumper or powertrain warranties, while others have separate policies. These programs cover anything from flat-tire changes and locksmith services to jump-starts and towing. Few reimburse incidental costs like motel rooms (if you have to wait for repairs).

Free Scheduled Maintenance

Some automakers include free scheduled maintenance for items such as oil changes, air filters and tire rotations. Some include consumables including brake pads and windshield wipers; others do not. They are typically for the first couple of years of ownership of a new car.
