There are 4 owner-reported tires & wheels complaints for the 2016 Mazda CX-9in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
The vehicle has tire pressure monitoring system malfunction warnings and parking brake malfunction warnings even after taking to dealership to be fixed. Was told it’s a known problem by Mazda, should be recalled, but there were not any current recalls for the issue.
Rear wheel trim partially detached from car while driving, safety risk of large plastic part being caught in rear wheel. Did not hit any debris but heard a loud noise as the part detached. Part is supposed to be held in place by 12 clips but multiple owners of Mazda CX-5 and CX-9 models report this problem. Mazda dealers deny there is a problem even when some new cars have only 3 clips installed. When I called Mazda USA to report, and asked them specifically for a federal government contact to report safety issues, they said calling them was the ONLY way to report an issue, which was not correct. Was told I would have to pay for the repair of this safety issue. See this website for the experience of other owners and a description of the problem: https://mazdas247.com/forum/t/2016-cx-9-wheel-well-trim-became-detached.123861160/ I also personally know another Mazda owner who had the same issue with the part falling off while driving.
I HEARD A PINGING SOUND COMING FROM ONE OF THE WHEELS. WHEN I GOT OUT AND LOOKED, I DISCOVERED THE WHEELS ARE BEGINNING TO FLAKE AND DEGRADE. I CONTACTED MAZDA CUSTOMER SERVICE AND WAS TOLD I WOULD HAVE TO COVER THE COST OF REPLACEMENT AS THE VEHICLE IS OUT OF WARRANTY.
P 255 / 50 R 20 104V M+S tread physically detached while driving at 70MPH Was able to steer and stop the vehicle and avoid a crash, partially due to fewer traffic on the road and the tire in question was on the rear driver side. Was able to replace the tire with my insurance. However no intimation about the failure was mentioned or no further action taken about safety of other tires previously on the vehicle The incident took place suddenly with a huge noise due to the broken tire hitting the wheel well and ripping off the fender.
