The 2008 Cadillac STS-V scores reasonably well in crash tests and sports a long list of standard safety gear.
Crash-test data is solid, with the National Highway Traffic Safety Administration (NHTSA) reporting four stars, front impact protection; four stars, side impact protection, driver; and five stars, side impact protection, rear passenger. Insurance Institute for Highway Safety (IIHS) tests are similar, with the Cadillac 2008 STS-V scoring "good" in frontal offset tests and "acceptable" in side impact tests.
Edmunds observes "a limited-slip differential, antilock brakes, stability control and traction control are all standard on the STS-V," along with a full complement of airbags. They add, "Rear parking assist, a lane departure warning system and blind spot warning system are also standard."
Cars.com likes the STS-V’s Intellibeam headlights, "which adjust their intensity based on the oncoming or leading vehicles."
Visibility is aided by the blind-spot alert system on the Cadillac 2008 STS-V, as described by Car and Driver: "Side Blind Zone Alert is what Cadillac calls its version of Volvo's Blind Spot Information System, or BLIS." Cadillac employs Side Blind Zone Alerting (SBZA) to keep the driver from sideswiping punier traffic caught in the large Caddy's blind spots. The system uses radar and lights up small icons in the car's mirrors to alert the driver to a possible collision hazard. Car and Driver is not completely enamored with the system, complaining, "We had to look at the mirror so intently to see if the icon were illuminated, we might as well have just turned our heads a little farther and manually checked the blind spots." If consumers don't like the system either, Car and Driver has the solution: "Fortunately, both the blind-spot alert and the lane-departure warning are quickly and easily deactivated."
