Safety Ratings

What do the Safety Ratings mean?

The National Highway Traffic Safety Administration (NHTSA) performs independent crash testing of new vehicles and then assigns them a score based on their performance. The overall crash test rating is based on how a vehicle performs in the following tests:

Driver Crash Grade:

Measures the chance of a serious injury to a crash test dummy that is placed in a driver's seat and driven into a fixed barrier at 35 MPH. A five-star rating means there is 10 percent or less chance of injury.

Passenger Crash Grade:

Similar to the driver crash grade, only now the focus is on the passenger.

Rollover Resistance:

Simulates an emergency lane change to measure the likelihood of a vehicle rolling over. A five-star rating means there is 10 percent or less risk of rollover.

Side Impact Crash Test - Front:

Focuses on the front side of a vehicle. It simulates crashes that can occur in intersections by striking a 3,015-pound weight against the side of a vehicle at 38.5 MPH. A five-star rating means there is 5 percent or less chance of injury.

Side Impact Crash Test - Rear:

Similar to the front side impact test only now the focus is on the rear passenger.

Original Warranty 

Original Warranty

An original warranty is the warranty associated with a vehicle when it is brand new. In addition to the original warranty, select items, like tires, are typically covered by respective manufacturers. Also, an act of Federal law sometimes provides protection for certain components, like emissions equipment.

The original warranty is often broken down into multiple sections, including:

Basic Warranty:

Typically covers everything except for parts that wear out through normal use of the vehicle. Examples of non-covered items are brake pads, wiper blades and filters.

Drivetrain Warranty:

This warranty covers items the basic warranty does not protect. Wear and tear items such as hoses will not be covered, but key items like the engine, transmission, drive axles and driveshaft often will be.

Roadside Assistance:

The level of service differs greatly with this warranty, but many manufacturers offer a toll-free number that helps provide assistance in case you run out of gas, get a flat tire or lock your keys in the car.

Corrosion Warranty:

This warranty focuses on protecting you from holes caused by rust or corrosion in your vehicle's sheet metal.

Please check the owner's manual, visit a local dealership or look at the manufacturer's website to learn more about the specifics of the warranties that apply to a vehicle.
