In owners' own words
Vehicle is a 2006 Buick Lucerne cx with 40,000 miles. About 2 months ago it started to go dead without any warning.
Aluminum V8 engine leaking oil profusely. Now getting smoke and odor while driving. My concern is that oil is leaking on to the hot exhaust manifold and could possibly ignite.
Since about 60,000 miles, the car it stalls out. It can stall going 70 MPH down the interstate, stall at stop signs, stall pulling out of an intersection.

Recalls for the 2006 Buick Lucerne: 4
This defect can affect the safe operation of the airbag system. The key fob (if applicable), should also be removed from the key ring. If the key is not in the run position, the air bags may not deploy if the vehicle is involved in a crash, increasing the risk of injury.
However, there have been new reports of thermal incidents on hwfs modules after this improvement was installed. These incidents resulted from a new failure mode attributed to the device's thermal protection feature. It is possible for the heated washer module to ignite and a fire may occur.
A short circuit on the printed circuit board for the washer fluid heater may overheat the control-circuit ground wire. This may cause other electrical features to malfunction, create an odor, or cause smoke increasing the risk of a fire.
On certain vehicles equipped with a V8 engine,the power steering hose connectors may have been inadequately crimped which could result in a fluid leak. If this were to occur, power steering assist may be lost and increased steering effort would be required at low speeds. Also, if the power steering fluid were to contact hot engine parts, an engine compartment fire could occur.
A recall may cover only some cars of a model year; the campaign size counts every model and year it lists. Enter your VIN at nhtsa.gov/recalls: dealers fix open recalls free.
