For enhanced safety, the front shoulder belts of the Chevrolet Impala are height-adjustable, and the rear seat shoulder belts have child comfort guides to move the belt to properly fit children. A better fit can prevent injuries and the increased comfort also encourages children to buckle up. The Volvo S90 has only front height-adjustable seat belts.

Both the Impala and the S90 have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, height-adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available crash mitigating brakes, lane departure warning systems, blind spot warning systems, rear parking sensors and rear cross-path warning.

Chevrolet's powertrain warranty covers the Impala 1 year and 10,000 miles longer than Volvo covers the S90. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the S90 ends after only 4 years or 50,000 miles.

There are over 10 times as many Chevrolet dealers as there are Volvo dealers, which makes it much easier should you ever need service under the Impala's warranty.

The Impala has a standard “limp home system” to keep drivers from being stranded if most or all of the engine's coolant is lost. The engine will run on only half of its cylinders at a time, reduce its power and light a warning lamp on the dashboard so the driver can get to a service station for repairs. The S90 doesn't offer a lost coolant limp home mode, so a coolant leak could strand you or seriously damage the car's engine.

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it's being repaired. Consumer Reports rates the Impala's reliability 63 points higher than the S90.
