Engine Coolant Leaking from rear of engine near Exhaust / turbocharger at Cylinder Head. No Warning Lights indicating problem until coolant level low causing overheating and fire risk. Rear Brakes not releasing completely from "City Mode" where brakes are kept close to rotor "to increase braking response in City driving" - causes premature brake wear, warped brake rotors (reoccurs within 10K miles from new / replaced rotors) Front Bumper Fascia keeps coming loose at clips near headlights on both Driver and passenger side. Had replaced at dealership 3 times, but continues. Bumper coming loose and can obstruct headlights while moving around at highway speeds

I have noticed cracks on both sides of the front bumper on my 2016 Mazda CX-9. Mazda has issued a TSB 09-022-20-3720, however, the cracks recently appeared and my car is no longer under the manufacturer's warranty.

Driver stopped vehicle in a driveway with minimal slope, shifted the vehicle in park, turned off the vehicle and exited. Driver proceeded to rear passenger door to retrieve 1 year old from car seat. After retrieving child from car seat, driver felt rear passenger door pushing into her leg, back and head. Vehicle proceeds to roll out of the driveway backward while in park. Driver and child escape vehicle's rear passenger side door, which is pushing them along in the vehicle's path toward residential street. Vehicle continues rolling in park backward down residential street, through a 3-way stop intersection, up a curb, through a yard and into a bush on a private property. A witness who helped retrieve the vehicle on behalf of the driver noted the vehicle was still in park when he tried to remove it from the bush. No one was severely injured but driver has sustained bruising on leg and severe emotional distress.
