This is obvious, given that Infiniti cars are much more powerful.

The Q50 model can serve you between 250K and 300K miles. If you drive around 15K miles a year, you need to shell out excessive amounts for repairs and replacements only after 15 to 20 years. According to US News, the Infiniti Q50 2022 has overall reliability and quality score of 83/100. The basic warranty on these cars lasts for the first 60K miles or 4 years.

So, drivers cruising along for 15K miles on average each year can expect these cars to provide up to 20 years of service. Evidently, you can put on atleast 250,000 miles on your QX60.

Considering high mileage, one can settle for a QX60 with 120K miles on the odometer safely. The QX60 models have been in the US streets for two generations.

On the other hand, more than 24% of Infiniti G35 cars last over 150K miles. These figures are impressive enough to demonstrate the long lifeline of this particular model.
