Understanding New Car Warranties

All new cars come with several warranties, from bumper-to-bumper coverage to those that cover specific components like the powertrain, emissions system and rust perforation. A new car can come with 6 or more warranties which can be daunting for its new owner to wade through.

Bumper-to-bumper: Often called the basic warranty, a bumper-to-bumper policy covers virtually every component on a new car. Most exclude regular maintenance, like fluid top-offs and oil changes, but a few luxury brands — most notably BMW and Saab — have separate free-maintenance provisions. Bumper-to-bumper warranties usually expire faster than powertrain warranties. American and Japanese cars typically come with a 3 year/36,000 mile warranty while luxury and more upscale brands carry a 4 year/50,000 mile warranty.

Glossary of Extended Warranty Terms (Part 2)

ECU: Electronic control unit.
The heart of the engine management system of a modern car. Regulates fuel delivery, ignition timing, engine idle speed and on some vehicles the transmission shift points.

Emissions Warranties:
The Federal Emissions Warranty guidelines are based on federal regulations and apply to vehicles in all 50 states. Vehicles are covered by two types of emissions control system warranty, “Emission Defect Warranty” and “Emissions Performance Warranty”. Depending on the state you live in, the Performance Warranty is for 3 years/50,000 miles.

Guide to New Car Factory Warranties and Extended Warranties

A new car comes with several different warranties from the factory, each covering specific parts of your vehicle.

Manufacturer’s Warranties

Basic Warranty - The specific terms established by each manufacturer (typically 3 years/36,000 miles for domestic and Asian vehicles and 4 years/50,000 miles for luxury cars) to repair vehicles for a specific time and/or mileage period. All factory installed parts and some dealer installed accessories are covered for defects and workmanship. Consumable items (tires, wiper blades, battery) are not covered under the basic warranty, although some of these parts may have their own warranty. Commonly called the “bumper-to-bumper” warranty, it is the most comprehensive of all new car warranties.
