I noticed in the last almost year a strange vibration in the SUV when I turn, as time went on it got louder. I had couple other parts replaced throughout this time thinking that was the issue. I than find out recently it was the read repeller shaft and another part which connects to the engine also part of the drive shaft. Noise occurs with driving I noticed after searching it is common with this SUV

When driving vehicle a severe shuddering vibration and loud noise emanated from front end of vehicle, as if front axel was going to fall off. Happened three times so far. Once to my wife, once to me, and once to the mechanic. Very frightening each time, causing drivers to pull over and turn off vehicle. Then vehicle drives ok for a while. Happened while driving straight forward. Mechanic states it is a failed power transfer unit. Mechanic's research indicated it is a big problem in mazda cx-9 vehicles, and a class action lawsuit was filed and resulted in a settlement. As far as I can tell that settlement does not cover my vehicle year (2008), and is limited to vehicles manufactured after 2010, and which meet certain specifications. Mechanic estimates repair will run in the $1100-$1500 range. Wondering if I have any recourse with regard to this problem and the fact that it seems a manufacturing defect rather then normal wear and tear.

When accelerating after driving for a few minutes maybe 10-15 after the vehicle has had time to warm up, as I am applying pressure to the gas pedal and it is shifting into gears (usually into gears 3,4, & 5) the vehicle is showing that it is into the next gear but you feel it shift after the fact so it is delayed and as accelerating it feels as though it is lagging and trying to shift but can't fully right away. I am only submitting this complaint because I know a couple others with this make of vehicle but different years and they stated they have the same issue with their vehicle as well

Car make weird vibration noise in the back end . Went to different mechanics and it's a transfer case and driveshaft issue. . Looks the problem is in design. Mazda recalled the transfer case from 2010 model and later but not before. Since the same part is used in earlier models requesting recall on earlier models too. I went to 4 different transmission shops and everyone told me that each and every mazda cx-9 comes to them has same issue. Called dealership and they said the extended warranty is after 2010. They have same parts and I or other owners can't afford the repair and it's a manufacturing fault. Looking forward to get help from the federal safety agency

My wife was driving the kids and all of the sudden the car started to make loud noise could not move forward and forced her to stop. Next day we towed to the mechanic's and was told the differential was cracked and it has been several cases of this happening to this car. A week after getting that fixed, I still hear notices when I am driving below 30mils. Now the mechanics tells me the back axle is leaking oil right next to the back differential. This needs to be investigated before a lose of life. If my wife was driving in a highway, there would have been a major accident.
