Bought '22 CX-9 Touring Plus 3 months ago. Love the car. Or should I say "loved"... Until recently....
When I bought it, the vehicle had 3 OEM Bridgestones and 1 brand new Goodyear installed. Bridgestones had about 6/32 on them, Goodyear - 10/32. Me, being the perfectionist, and knowing that substantial variance in tread wear can cause problems with AWD, decided to buy another 10/32 Goodyear to match the one already installed on it. That's when the problems started.....
I purchased an "used, driven once" Goodyear off of ebay and had it installed (by Mazda dealer). Also had the alignment and 4-wheel balancing done. Started to exprience pretty bad vibration at speeds 40+ mph, getting progressively worse after 70mph. Had the tires balanced five (5) times - twice by dealership, then Discount tire, Pep boys, some random shop... Nothing helped. Decided that the ebay Goodyear tire was probably defective. Had the two Goodeyars replaced with two Michelin Defenders (also used). No change. Vibration changed to where it only happens at 60mph+. But now I also started to experience a weird humming/growling noise coming from front axle. So, I thought it might be a wheel bearing. Or the stupid used Michelins... Or maybe the two remaining OEM Bridgestones (but they were fine when I bought the car). So, I decided f...k this.. and went to Discount tire and bought two new Michelines to replace the OEM Bridgetones. And also had them inspect the two other MIchelins (and they said everything was fine with them, they have about 10/32 tread left and no irregularities or abnormal wear).
After I installed the two new Michelins things got worse.... Vibration at 60mph is now so bad that I hate the car. The humming/growling noise from front axle is still there. Dealer had the wheel bearings checked - said everything is fine...
I'm at a loss... The dealer (Freeman Mazda in Dallas) is great... over the years I've owned two Miatas, two Mazda 3s, another CX-9, and now this '22 Touring Plus, and never had any problems with the dealer, they are always willing to help... but this time I don't really know what to do next. They already had the tires balanced twice at no cost, checked suspension, bearings, etc. and said everything looked fine. Vehicle has 17k miles on it... The humming/growling noise doesn't really change with speed (or when turning), but gets worse when the road gets worse, and is most noticeable when just cruising at around 50mph. Can also feel it on the gas pedal... Feels like something is rubbing... And then at 60mph the vibration kicks in....
Any suggestions will be much appreciated.
