Hyundai XG350 owners have reported a total of 396 problems for their cars built in the 6 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 Hyundai XG350. The 2005 Hyundai XG350 cars have the most problems reported (169 problems).
The following chart shows the 21 most common problems for Hyundai XG350 cars. The number one most common problem is related to the vehicle's air bags (117 problems). The second most common problem is related to the vehicle's vehicle speed control (72 problems).
|Problem Category||Number of Problems|
|Vehicle Speed Control|
|Engine And Engine Cooling|
|Gasoline Fuel System|
|Other Fuel System|
|Unknown Or Other|
It would not be fair to compare the Hyundai XG350 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 XG350 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 Hyundai XG350 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 Hyundai XG350 is to use the total number of problems reported during the vehicle's first year in service, as shown in the Table 4.
