Chevrolet Blazer owners have reported a total of 5,616 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 Chevrolet Blazer. The 1996 Chevrolet Blazer cars have the most problems reported (1,156 problems).
The following chart shows the 29 most common problems for Chevrolet Blazer cars. The number one most common problem is related to the vehicle's service brakes, hydraulic (787 problems). The second most common problem is related to the vehicle's engine and engine cooling (619 problems).
It would not be fair to compare the Chevrolet Blazer 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 Blazer 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 Chevrolet Blazer 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 Chevrolet Blazer is to use the total number of problems reported during the vehicle's first year in service, as shown in the Table 4.
