Chevrolet Monte Carlo - Problems, Statistics, and Analysis

Chevrolet Monte Carlo owners have reported a total of 2,102 problems for their cars built in the
14 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 Monte Carlo.
The 2001 Chevrolet Monte Carlo cars have the most problems reported (303 problems).

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

The following chart shows the 26 most common problems for Chevrolet Monte Carlo cars.
The number one most common problem is related to the vehicle's electrical system
(545 problems).
The second most common problem is related to the vehicle's engine and engine cooling (419 problems).

Compare Reliability Across Model Years Using PPMY Index

It would not be fair to compare the Chevrolet Monte Carlo 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 Monte Carlo 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 Monte Carlo 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.

Table 3. Use PPMY Index to Compare Reliability Across Monte Carlo Model Years

Another way to measure the reliability across the model years of the Chevrolet Monte Carlo
is to use the total number of problems reported during the vehicle's first year in service, as shown in the Table 4.
