The 2009 Buick Lucerne has crash-test scores that are decent—though not noteworthy in a positive sense—for such a large, overtly secure-feeling sedan. Feature-wise, to the editors of TheCarConnection.com, the Lucerne is hit and miss with respect to safety features. The base CX model, which stickers at more than $30,000, doesn’t include electronic stability control, an active safety feature that helps avoid accidents. However there are several high-tech active-safety options that help redeem top-of-the-line Lucernes.
Crash-test ratings are strictly middle-of-the-road for a big sedan. The 2009 Buick Lucerne got four- and five-star results in crash tests administered by National Highway Traffic Safety Administration (NHTSA), and “good" and "acceptable" ratings from the Insurance Institute for Highway Safety (IIHS) for frontal and side crash protection, respectively.
The Buick Lucerne's "Ultrasonic Rear Parking Assist and an electronic stability system are optional," reports Cars.com. "Six airbags are standard in all Buick Lucernes, including side-impact and side curtain airbags," along with "all-disc antilock brakes."
"Lane-departure warning and blind-spot detection systems" are "mildly useful,” says AutoWeek, also noting that "unlike the lane-departure system offered by Infiniti, the one Buick uses is not nearly as intrusive."
