No dashboard warnings, no overheat messages, no visible symptoms before that. That's what makes this failure mode dangerous: it loses coolant silently, and you find out from a puddle or from an overheat, not from the car telling you.  A Mazda dealership confirmed the failure during a multi-point inspection by one of their master technicians (September 2026): coolant leaking from the back of the cylinder head, no signs of coolant and oil mixing, and a scan showing no history of overheating. Their recommendation is cylinder head replacement. The vehicle is available for inspection on request.  This exact failure mode is a known design defect on 2016-2020 CX-9s with the 2.5T engine. Mazda itself acknowledged it -- special service program CSP11 (\"Coolant Leaks at Cylinder Head Warranty Extension,\" NHTSA doc MC-11011136-0001, issued October 2024). That program extended the powertrain warranty to 10 years / 120,000 miles for precisely this failure, covering vehicles produced before June 2020 -- which includes this one.  Here's the part that gets me: my vehicle is in the CSP11 VIN range, and the defect was diagnosed inside the program's 10-year date window. But the odometer is past 120,000 miles, so coverage was denied. The owner notification for CSP11 didn't go out until November 2024 -- to original owners. I bought this vehicle used, and never received that notice, so the extension was effectively invisible to the person actually driving the car as it crossed the mileage threshold. A manufacturer-documented design defect shouldn't lose all coverage on a technicality for used owners.  Cause: UNKNOWN. The crack is at the cylinder head stud bolt hole area, matching Mazda's own documentation (TSB 01-002/23). No maintenance schedule prevents a casting crack.","products":[{"type":"Vehicle","productYear":"2016","productMake":"MAZDA","productModel":"CX-9","manufacturer":"Mazda Motor Corp."}]}]}
