Buick Enclave - Problems, Statistics, and Analysis

Buick Enclave owners have reported a total of 1,651 problems for their cars built in the
11 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 Enclave.
The 2008 Buick Enclave cars have the most problems reported (626 problems).

Table 1. Total number of problems by model year for Buick Enclave

The following chart shows the 26 most common problems for Buick Enclave cars.
The number one most common problem is related to the vehicle's steering
(357 problems).
The second most common problem is related to the vehicle's power train (226 problems).

Compare Reliability Across Model Years Using PPMY Index

It would not be fair to compare the Buick Enclave 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 Enclave 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 Enclave 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 Enclave
is to use the total number of problems reported during the vehicle's first year in service, as shown in the Table 4.
