2009 Mazda CX-9 Transmission and drivetrain Problems

“I have maintained my 2009 Mazda cx9 to date and only have 48,000 miles. I started hearing a weird noise in the front wheel (humming) it got progressively worse . Now my mechanic tells me that the differential is going. This has to be a manufacturers defect due to the low mileage and the upkeep of this vehicle. Assistance with this would be greatly appreciated. In addition, I've looked online and see that other owners are experiencing the same issue.”

“Car dangerously shudders and hesitates when accelerating & at certain highway speeds increasingly for last two years due to faulty torque converter design per two transmission diagnostics done.

“The contact owns a 2009 Mazda CX-9. While driving approximately 45 MPH, the vehicle lost acceleration and a rattling noise was heard.

The vehicle was taken to an independent mechanic who determined that the transfer case was fractured and needed replacement. The vehicle was not taken to the dealer for diagnostic testing. The manufacturer was notified of the failure. The vehicle was not repaired. The approximate failure mileage was 125,000.”
