Not sure if the issue is related but often times a Nissan having a difficult time accelerating from a dead stop is an issue in the CVT. These transmissions can be finicky and need to be serviced on time or else you're looking at a big repair bill if it's not under warranty. The transmission fluid should be flushed around every 50 to 60 thousand miles. If the fluid gets burnt then it will start to cause issues taking off from a stop, especially once the car gets hot. Take it to the dealership to be serviced to make sure you're getting the correct fluid.
