Mercury Mariner owners have reported a total of 1,674 problems for their cars built in the 7 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 Mercury Mariner. The 2008 Mercury Mariner cars have the most problems reported (549 problems).
| Model Year | Number of Problems |
|---|---|
| 2011 Mariner | |
| 2010 Mariner | |
| 2009 Mariner | |
| 2008 Mariner | |
| 2007 Mariner | |
| 2006 Mariner | |
| 2005 Mariner |
The following chart shows the 26 most common problems for Mercury Mariner cars. The number one most common problem is related to the vehicle's steering (557 problems). The second most common problem is related to the vehicle's power train (216 problems).
It would not be fair to compare the Mercury Mariner 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 Mariner 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 Mercury Mariner 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 Mercury Mariner is to use the total number of problems reported during the vehicle's first year in service, as shown in the Table 4.
