CarComplaints.com Notes: The QX60 is the only Infiniti in North America that uses Nissan's Continuously Variable Transmission (CVT). This isn't necessarily a good thing.

I purchased the vehicle and it seemed that nothing was wrong with it at all, it drove great and I was assured no issues existed at the time of purchase. Approximately 2 1/2 weeks later (after barley driving it much at all), I noticed severe jerking/juddering - mainly after coming from a stop to go or turn situation as if it seemed to have problems shifting gears along with clunking and/or whistling noises while driving. The problem has rapidly increased and now out of nowhere, the RPM levels will shoot all the way up while the car cannot accelerate more than 10ish miles which causes me to have to pull over wherever I am, shut off my engine, restart, and drive until it happens again (usually in the next 5 - 10 minutes).

It appears driving at higher speeds such as on the highway, this happens less, but in areas where the speed limit is 50 or under, this is guaranteed to happen without warning. I took it to AutoZone as soon as the check engine light came on and it provided the code P1715 - Input Pulley Speed Signal related to Power Train System. Secondary DTCs were PO776 - Pressure control solenoid "B" performance/stuck off. Pressure control solenoid B function. This is a major safety issue as I cannot pullover due to the unexpected rate this happens. I have researched extensively and found that others with the same make/model are experiencing the exact same issue.
