Looking at a used 2013 Pathfinder SL and trying to weed out possible issue before making decision
This type of question shows up here every other day it seems like. The vehicle is 7 years old and no one can predict what will go wrong with it . It could have had some problems taken care of in the past.
The standard reply is that you pay a trusted shop to look at what ever you want to purchase and hope for the best.
The Pathfinder has a CVT type of automatic transmission, there are a number of transmission complaints for this vehicle.
