Chevrolet Uplander owners have reported a total of 692 problems for their cars built in the 6 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 Uplander. The 2005 Chevrolet Uplander cars have the most problems reported (216 problems).
The following chart shows the 25 most common problems for Chevrolet Uplander cars. The number one most common problem is related to the vehicle's electrical system (132 problems). The second most common problem is related to the vehicle's structure (78 problems).
|Problem Category||Number of Problems|

|Vehicle Speed Control|
|Unknown Or Other|
|Traction Control System|
It would not be fair to compare the Chevrolet Uplander 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 Uplander 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 Uplander 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 Uplander is to use the total number of problems reported during the vehicle's first year in service, as shown in the Table 4.
