Nissan 350Z owners have reported a total of 763 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 Nissan 350Z. The 2003 Nissan 350Z cars have the most problems reported (325 problems).
The following chart shows the 23 most common problems for Nissan 350Z cars. The number one most common problem is related to the vehicle's suspension (149 problems). The second most common problem is related to the vehicle's power train (139 problems).
|Problem Category||Number of Problems|
|Engine And Engine Cooling|
|Gasoline Fuel System|
|Other Fuel System|
|Vehicle Speed Control|
|Unknown Or Other|
|Electronic Stability Control|
|Diesel Fuel System|
It would not be fair to compare the Nissan 350Z 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 350Z 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 Nissan 350Z 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 Nissan 350Z is to use the total number of problems reported during the vehicle's first year in service, as shown in the Table 4.
