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.
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
