The car continues to downshift two or three gears, i.e. from 5th to 3th or from 6th to 3th, when the I stop accelerating down the road and I touch the brake. Sometimes, I don't need to touch the brake and the car downshifts very hard. Recently I made a complaint at the dealer, and they asked me to bring the car for a test. They did the test (hopefully) and said it is good what was happening. No change was made.
