I bought my 2014 Maxima SV with sport package used a few months ago with 34,000 one owner dealer serviced miles from a Toyota dealer. Records showed a new CVT installed under warranty at Nissan in 2017 at 27,000 miles. After a few days of ownership, the car started loosing power on a take off from a dead stop. It was like the fuel was shutting off, transmission was slipping or something bad. Returned it to Toyota where I bought it, and they told me to take in to Nissan as it was still under factory warranty, and they owned both dealerships. Well after the car had been in the shop for over a month, they finally figured out what was wrong with a Nissan engineers help. The wiring harness to the crank sensor was installed to tight at the factory, and when the motor moved when gassing it hard, it had pulled the wiring apart inside of the wiring to the plug to the crank sensor. In records to car, it had also be in for a broken motor mount around the time the CVT was replaced. So this might have caused it too. Car now runs like new.
