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 Traverse.
The 2010 Chevrolet Traverse cars have the most problems reported (749 problems).

Table 1. Total number of problems by model year for Chevrolet Traverse

The following chart shows the 24 most common problems for Chevrolet Traverse cars.
The number one most common problem is related to the vehicle's steering
(767 problems).
The second most common problem is related to the vehicle's engine and engine cooling (461 problems).

Compare Reliability Across Model Years Using PPMY Index

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