Buick Regal owners have reported a total of 2,173 problems for their cars built in the 21 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 Regal. The 1998 Buick Regal cars have the most problems reported (310 problems).
The following chart shows the 23 most common problems for Buick Regal cars. The number one most common problem is related to the vehicle's engine and engine cooling (581 problems). The second most common problem is related to the vehicle's electrical system (379 problems).
It would not be fair to compare the Buick Regal 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 Regal 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 Regal 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 Regal is to use the total number of problems reported during the vehicle's first year in service, as shown in the Table 4.
