My Nissan Altima is normally fine but after about 40 minutes to an hour of driving even in cool temperatures the car stops wanting to accelerate much and the RPM needle will jump from 1-2k to 5k almost instantly when applying more gas. I can be at 5k RPMs and barely climb 1 to 2 mph every few seconds in my car. This issue will persist till I turn the car off for a short while. Once The car has cooled down and been idle for a bit the car works fine again for 40 to 60 minutes.
I’m worried is the CVT. Any ideas? I also don’t want to take it in because I doubt they’ll get the problem to reproduce unless they drive it for up to an hour.
