Buick Century owners have reported a total of 1,374 problems for their cars built in the 10 model years listed in the chart below. The chart shows the number of problems reported across all service years for each given model year of the Buick Century. The 1999 Buick Century cars have the most problems reported (246 problems).

The following chart shows the 25 most common problems for Buick Century cars. The number one most common problem is related to the vehicle's engine and engine cooling (200 problems). The second most common problem is related to the vehicle's electrical system (153 problems).
It would not be fair to compare the Buick Century 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 Century 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 Century 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 Century is to use the total number of problems reported during the vehicle's first year in service, as shown in the Table 4.
