Based on a glance at the list of safety features offered on the 2009 Cadillac STS-V, you might expect only the best marks resulting from crash tests. Instead its results are a bit disappointing for such a large, expensive sedan.
The Insurance Institute for Highway Safety (IIHS) scored the 2009 Cadillac STS-V "good" in frontal offset tests, but "acceptable" in side-impact tests. 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.
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. "Side Blind Zone Alert is what Cadillac calls its version of Volvo's Blind Spot Information System, or BLIS,” reports Car and Driver. "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."
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."
