The following chart shows the 24 most common problems for Buick Lucerne cars. The number one most common problem is related to the vehicle's electrical system (390 problems). The second most common problem is related to the vehicle's fuel system, other (114 problems).
It would not be fair to compare the Buick Lucerne of an older model year to newer model years since older vehicles have been in service longer and thus are expected to have more problems. In order to compare the reliability across Lucerne model years, we use the PPMY index which is defined as the problems reported per thousand vehicles per Year. A smaller PPMY index indicates greater reliability of the given model year cars.
PPMY = P / S / Y * 1000,
where P = total problems reported during the life of a Buick Lucerne model year; S = total units sold of the model year; Y = years since the debut of the model year (the age of the vehicle).
The results are shown in Table 3.
Another way to measure the reliability across the model years of the Buick Lucerne is to use the total number of problems reported during the vehicle's first year in service, as shown in the Table 4.
