I purchased this vehicle with 19K miles on July 31, 2020. I noticed on April 12, 2022, that there was a knocking noise coming from the left front suspension after leaving a Mazda dealership for an oil change. I called Mazda service and was told they only did an oil change. I have put 4 brand new tires and have replaced the front/back brakes, rotors and still hear noise going over uneven pavement. I brought it to my own mechanic twice and he hears the noise but informed me that he cannot order any suspension parts at all for Mazda CX9. He said Mazda are forcing Mazda customers to go to a Mazda dealership. He called 5 different places to purchase strut. suspension and was told they had none. He also said Mazda has a special wrench to work with having to do with suspension and he cannot get one. My mechanic had my vehicle for 3 days and said it's definitely a suspension issue. My Mazda only has 35K miles. In 2 years, I have only driven 16K (8K) per year. There is no way a suspension should go after only 35K miles. I am not off roading or abusing the vehicle. Can't NHSTA assist with this issue? This is very serious. I am afraid to drive this Mazda now.

I bought a used 2017 Mazda Cx-9 from West shore Honda in tampa in July of 2020. They screwed me financially and I'll handle that separately. There has been an ongoing issue since the first few days after buying the car. I've complained multiple times via email and phone. I've been trying the service department countless times. They keep stating it's a tire issue. To the point they have replaced the tires 3 times. After the second time I had already decided it's not tires. The car has a very rough ride when I'm motion. Once you got 80 it wobbles. After several weeks the wobble can be felt at lower speeds of 55/60. The check engine light comes on but I'm told there's no codes when they diagnostic the reading. I've expressed that when I pull into my garage within 30 seconds to a minute there's a loud pop it's when the car is not in motion when it's been parked and turned off is when I noticed it. I brought it to my personal mechanic just to look at and drive and he's pretty certain it's a powertrain bearing or something of those sorts. Brought it back to westshore and they put another set of tires on it. This is been going on now for 9 months and after doing research online and some of the NHTSA ids this is a problem and I do not feel safe. And it needs to be handled the amount of complaints in times that I visited that dealership to fix this problem and all they do is put new tires on it is asinine. I have tons of documentation the same documentation that's at the dealership I do everything via email for that reason.
