Hello. There are a few common causes of this on your vehicle. Most of the time it is caused by an issue with the transmission fluid being old or contaminated or it may be a problem with one of the speed sensors. Being that it has the CVT transmission it may also be that it is failing. I usually check the computer for codes first.

There are some pressure codes that commonly come up and those will pertain to a transmission failure. If those codes are not present, then I check the fluid. If the fluid is really dark, then the transmission may be failing.

If not then I check the signals from the sensors to see if they are reading correctly. If you want to have this shifting problem checked out, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose this shifting problem.
