Two problems related to power train have been reported for the 2013 Mazda CX9. The most recently reported issues are listed below.
Trans seems to slip going in and out of 4th gear. Just bought this car 3 days ago and it has been a consistent problem that didn't start until an hour after the purchase once it warmed up. Looks like it's the transfer case, this SUV only has 106k on it ! this is absolutely ridiculous, Mazda needs to offer a recall for this issue so those who have the issue don't have to fork out more money for an issue that Mazda is well aware of with their vehicles.
I bought my cx-9 new in 2013, car now has 102,000 miles. Car started to shutter when getting off the exit from a major highway. The problem was discovered with the power transfer unit. Picture indicates heavy spline wear and corrosion. Transmission spline also has corrosion and wear. This was a very dangerous situation. There's no maintenance required by Mazda for the ptu or the transmission. Mazda should issue a recall on both the ptu and the transmission. This is a known issue with Mazda and discussed on many internet forums.
