 Edmunds asked me to update my remarks about my 2015 CX-9 Touring.  It now has about 21,000 miles.  The tires it came with were replaced as they wore out at about 20K miles.  There has always been excessive wind noise, I thought it was the first set of tires but now the wind noise has still not gone away.  The seats have a wrinkle issue that is getting worse and it really looks bad.  I finally got a Mazda dealer out of my area to replace the warped front rotors and fix a transmission oil leak.  My local dealer claimed they cold not find the leak that was dripping on my driveway and also refused to replace the front warped rotors under warranty.  This local dealer also refused to test drive my car for the front rotor issue unless I paid $193 - really insane as I bought a NEW car for the warranty never thinking getting it repaired would be such a hassle.  Gas mileage improved to 14 mpg, but it is still low compared to what Mazda states it should get.  After tests on the consumption level, Mazda claims this is within standards - I don't think so as this issue is addressed at numerous sites on the internet.  Engine is starting to burn oil.  Just added .5 quart after driving about 2,000 miles from the last oil change.  Driver's windows makes noise going down and Mazda refuses to fix.  The rear trunk door doesn't close correctly.  I had it adjusted just after I bought the car and it still is not closing correctly.  The dealer wants me to pay to fix it - really annoying!!!  Most recently the front seat belts would not retract and the buckle would get caught between the door and body causing damage when closing the door.  I took it to my local dealer who demanded $140 to just look at the issue.  To Mazda's credit, customer relations agreed to pay the dealer to fix this issue, however, it required almost one hour on the phone with Mazda to get the seat belt issue paid for.  If I had to do it over again, I would NOT have purchased this 2015 Mazda CX-9.  This is the first review:Issues that Mazda and its dealers have not corrected: Ongoing front brake judder that started before 12,000 miles and is still not resolved.  Brakes make a grinding noise and the steering wheel shakes when going down hill and now the dealer wants $193 to just test drive the car once it passed the 12K mark.  Three trips to a dealer to fix a transmission oil leak which is dripping and they state they can not find it but an independent shop found the leak in about 1 minute.  Driver side window makes noises when it goes down and the dealer wants $129 to look at it and the car is under warranty.  Both headlights were replaced when the clear coat came off.  The Ford engine gets about 13MPG and shakes at idle.  Dealer tried to put the blame on me for this stating I used the wrong kind of gas - it takes regular from the Chevron station down the street.  Finally dealer admitted that the Ford engine has known issues.  Rear door latch was fixed early on, then it is more or less broken again and dealer wants $125 to fix.  The leather seats began wrinkling early on and Mazda fought me long and hard to save it self some money.  Refused to fix the issue and gave me about a quarter of what it would cost to fix the seats as there is a suede like material in between the leather in the seats that wrinkled and could not be repaired without replacing the seats altogether.  Dealer insisted that the 2015 CX-9 model had to have synthetic oil or my warranty would be voided.  I called customer support at Mazda, told them that the manual states regular oil is OK.  Mazda called the dealer and dealer agreed to use regular oil.  Makes me wonder how many customers have paid for synthetic oil when they didn't need it as synthetic cost much more.  I now regret I bought this car.
