Lincoln MKZ owners have reported a total of 1,040 problems for their cars built in the 12 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 Lincoln MKZ. The 2008 Lincoln MKZ cars have the most problems reported (233 problems).
The following chart shows the 22 most common problems for Lincoln MKZ cars. The number one most common problem is related to the vehicle's air bags (578 problems). The second most common problem is related to the vehicle's service brakes, hydraulic (57 problems).
|Problem Category||Number of Problems|
|Vehicle Speed Control|
|Engine And Engine Cooling|
|Other Fuel System|
|Electronic Stability Control|
|Gasoline Fuel System|
|Traction Control System|
It would not be fair to compare the Lincoln MKZ 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 MKZ 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 Lincoln MKZ 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 Lincoln MKZ is to use the total number of problems reported during the vehicle's first year in service, as shown in the Table 4.
