Note that the 3.8L engine did have some well-documented issues with intake gaskets and leaks thereof – so be sure to have the Lucerne you’re considering checked for signs of this problem by a GM mechanic.
If the Lucerne you’re considering exhibits sporadic power delivery, uneven acceleration, hesitation, or clumsy shifting, it may be suffering from one of several wiring or sensor-related problems. These may include bad battery grounds, chafed or corroded sensor wiring, or even just aged spark-plug wires. In many instances, drivability issues with the 3.8L V6 are electronic and not mechanical in nature.
Finally, check for signs of moisture or water damage in the trunk, ensure the keyless entry system works as expected, and have the underside of the 4.6L V8, if equipped, checked for signs of oil leakage.
The Verdict Of A Used Buick Lucerne: To maximize the potential for a trouble-free ownership experience, opt for as new a model as your budget will allow – sticking with the 3.8L engine where possible. A lower-mileage unit with a good portion of the factory warranty remaining will add further confidence.
