Bough a used 2015 RAV4 XLE a couple of weeks ago and love the car. I was cleaning it up and went to check the oil. The dipstick did NOT want to come out of the tube. I put some penetrating oil on it and finally gave it a good yank and I did get it out but it did not want to go back in very easily either. I solved this problem by using the wire brush from my pistol cleaning kit along with some WD40. A few twists once in the tube and now it slides in and out snugly and smoothly. Just an FYI.
