Mazda CX-9 Problems by year

This model has a Company know defect with its cylinder block involving hairline cracks near the exhaust manifold .

They are trying to charge me $7500 for the fix after i asked for goodwill fix since i came to them before the problem was confirmed but...

We recently noticed a coolant smell upon cold start up of our 2019 Mazda CX-9 Signature. Upon further investigation, we found that there is a Service Bulletin (TSB-01-013/21) issued by Mazda for a manufacturer's defect in the cylinder head causing coolant leaks into and around the exhaust manifold. This is a known and widespread issue, but our car's warranty has lapsed due to mileage (187K miles).

The contact stated that the seller informed him that she and her fiancé had replaced the cluster gauge.

The front passenger seat heating element in my 2022 Mazda Model, CX-9 malfunctioned, failing to regulate temperature and creating an immediate thermal safety and fire hazard. While operating the vehicle normally with the passenger side seat heater turned on, the system rapidly reached temperatures far exceeding normal comfort parameters. The heat became intense enough to cause smoke to fill the car, a flame to appear on the seat, and a giant burned hole in the seat. To prevent an active vehicle fire, I had to...

2021 Mazda CX-9 (VIN: JM3TCBDY3M0538768 / 72,400 mi) Vehicle has suffered complete, sudden loss of motive power at high freeway speeds on four separate occasions. Without warning, the engine loses all propulsion, essentially stalling mid-traffic and forcing me to dangerously coast across active freeway lanes to the shoulder. This creates an extreme risk of a high-speed rear-end collision. No crash or injuries have occurred yet, but the car is entirely unsafe to drive. The authorized Mazda dealership has been...
